Khella Khella (Ammi visnaga) is an ancient medicinal plant native to the Mediterranean region order genuine tadalafil online erectile dysfunction foundation, where it has been used in the treatment of angina and other heart ailments for thousands of years order tadalafil discount erectile dysfunction video. Several of its components have demonstrated effects in dilating the coronary arteries. Its mechanism of action appears to be similar to that of the calcium-channel-blocking drugs. Since the late 1940s, there have been numerous scientiﬁc studies on the clinical effect of khella extracts in the treatment of angina. The concluding statement in a 1952 study reads: “The high proportion of favorable results, together with the striking degree of improvement frequently observed, has led us to the conclusion that khellin, properly used, is a safe and effective drug for the treatment of angina pectoris. Although most clinical studies used high dosages, several studies show that as little as 30 mg khellin per day appears to offer equally good results with fewer side effects. In a series of 283 patients treated by Clarke and his colleagues from 1956 to 1960, 87% showed improvements in their symptoms. Heart patients improved, and patients with blocked arteries in the legs, particularly those with diabetes, avoided amputation. However, it now seems more related to chelating out excess iron and copper, minerals that, in the presence of oxygen, stimulate free radicals. Free radicals damage the cells in the artery and are a primary reason for atherosclerosis. The conclusion from a Cochrane review summarizes the situation well: “At present, there is insufﬁcient evidence to decide on the effectiveness or ineffectiveness of chelation therapy in improving clinical outcomes of patients with atherosclerotic cardiovascular disease. Once angina has developed, restoring proper blood supply to the heart and enhancing energy production within the heart are necessary. Particularly important nutrients for accomplishing these results are vitamins C and E, carnitine, pantethine, CoQ10, magnesium, and arginine. Magnesium is of additional beneﬁt because of its ability to relax spastic coronary arteries and improve heart function. Hawthorn berries or extracts offer a number of beneﬁts to individuals with angina, including coronary artery dilation and improved heart muscle metabolism. Individuals with unstable angina pectoris (characterized by a progressive increase in the frequency and severity of pain, increased sensitivity to precipitating factors, progression of symptoms over several days, and prolonged coronary pain) require immediate medical attention. Diet The dietary guidelines given in the chapter “A Health-Promoting Diet,” as well as in the chapter “Heart and Cardiovascular Health,” are appropriate here. Onions and garlic (both raw and cooked), vegetables, and ﬁsh should also be increased, while the consumption of saturated fats, cholesterol, sugar, and animal proteins should be reduced. Patients with reactive hypoglycemia should eat regular meals and carefully avoid simple carbohydrates of all forms (e. Stress should be decreased by the use of stress management techniques such as progressive relaxation, meditation, and guided imagery. A carefully graded, progressive aerobic exercise program (30 minutes three times per week) is a necessity. Anxiety differs from fear in that while fear is a rational response to a real danger, anxiety usually lacks a clear or realistic cause. Though some anxiety is normal and even healthy, higher levels of anxiety not only are uncomfortable but also can lead to significant problems. The most common symptoms relate to the chest, such as heart palpitations (awareness of a more forceful or faster heart beat), throbbing or stabbing pains, a feeling of tightness or inability to take in enough air, and a tendency to sigh or hyperventilate. Tension in the muscles of the back and neck often leads to headaches, back pains, and muscle spasms. Other symptoms can include excessive sweating, dryness of the mouth, dizziness, digestive disturbances, and the constant need to urinate or defecate. Anxious individuals usually have a constant feeling that something bad is going to happen. They may fear that they have a chronic or dangerous illness—a belief that is reinforced by the symptoms of anxiety. Inability to relax may lead to difficulty in getting to sleep and constant waking in the night. Panic Attacks Severe anxiety will often produce what are known as “panic attacks”—intense feelings of fear. Panic attacks may occur independently of anxiety but are most often associated with generalized anxiety or agoraphobia. Causes Clinical anxiety, including panic attacks, can be produced by psychological problems as well as by biochemical factors such as caffeine, certain other drugs, and the infusion of lactate into the blood. The fact that these compounds can produce anxiety and panic attacks can be put to good use in understanding the underlying biochemical features of anxiety. Perhaps the most signiﬁcant biochemical disturbance noted in people with anxiety and panic attacks is an elevated blood lactic acid level and an increased ratio of lactic acid to pyruvic acid. Lactate (the soluble form of lactic acid) is the ﬁnal product in the breakdown of blood sugar (glucose) when there is a lack of oxygen. To illustrate how lactic acid is produced, let’s take the classic example of the exercising muscle. Muscles prefer to use fat as their energy source, but when you exercise vigorously there isn’t enough oxygen, so the muscle must burn glucose. Without oxygen, there is a buildup of lactic acid within the muscle; this is what causes muscle fatigue and soreness after exercise. Lactic Acid Conversion to Pyruvic Acid or Glucose The ﬁrst few steps of normal glucose breakdown can occur without oxygen, until pyruvic acid is produced. The next steps require oxygen and end in the complete breakdown of pyruvic acid to carbon dioxide and water. Because the exercising muscle needs energy, the muscle cells continue to convert glucose to pyruvic acid in a process referred to as anaerobic metabolism. With good circulation, the lactic acid is removed from the muscle and transported to the liver, where it can be turned back into pyruvic acid or even glucose if needed. All of this biochemistry plays a role in anxiety, because individuals with anxiety have elevated blood levels of lactate and a higher ratio of lactic acid to pyruvic acid when compared with normal controls. Furthermore, if people who get panic attacks are injected with lactate, severe panic attacks are produced. Reducing the level of lactate is a critical goal in the treatment of anxiety and panic attacks. Therapeutic Considerations The natural approach to anxiety builds upon the recommendations given for stress in the chapter “Stress Management. If you suffer from mild anxiety, follow all of the recommendations given in that chapter for diet, exercise, nutritional supplementation, calming the mind and body, and taking an adrenal adaptogen. If you suffer from moderate to severe anxiety, follow all of the recommendations in that chapter as well as those discussed below; substitute kava for the adrenal adaptogen. Lactate Levels As pointed out previously, increased lactic acid levels may be an underlying factor in panic attacks and anxiety. The goal is to prevent the conversion of pyruvic acid to lactic acid and to improve the conversion of lactic acid back to pyruvic acid. There are at least six nutritional factors that may be responsible for elevated lactate levels or ratios of lactic acid to pyruvic acid:1 1.

We determined the capacity of putative antidiabetic plants used by the Eastern James Bay Cree (Canada) to modulate key enzymes of gluconeogenesis and glycogen synthesis and key regulating kinases. Seven of the seventeen plant extracts signifcantly decreased G6Pase activity, Abies balsamea and Picea glauca, exerting an efect similar to insulin. In summary, three Cree plants stand out for marked efects on hepatic glucose homeostasis. Our studies thus confrm that the reduction of hepatic glucose production likely contributes to the therapeutic potential of several antidiabetic Cree traditional medicines. Type 1 diabetes afects mostly Approximately 370 million people in the world are young people and is due to an autoimmune destruction afected by diabetes. Te risk to develop Type 2 diabetes characterized by decreased insulin sensitivity in major target in Aboriginal population is three to fve times higher than the organs such as liver, muscle, and adipose tissues, in addition general Canadian population [4, 5].

Indeed, insulin, a hormone secreted by the increases catabolic pathways (increase of muscle glucose beta pancreatic cells, works by decreasing glucose production uptake,increaseofthefattyacidoxidation,andincreaseof in the liver, stimulating its uptake by skeletal muscle and the glycolysis).
Our present thinking generic tadalafil 10 mg without prescription erectile dysfunction girlfriend, our present mental habits buy tadalafil amex erectile dysfunction treatment natural medicine, our attitudes toward past experiences, and our attitudes to- ward the future—all have an influence upon old recorded engrams. Old Recordings Can Be Changed Another interesting finding is that the more a given en- gram is activated, or "replayed," the more potent it be- comes. Eccles and Sherrington tell us that the permanence of engrams is derived from synaptic efficacy (the effi- ciency and ease of connections between the individual neurons that make up the chain) and further, that synaptic efficiency improves with use and diminishes with disuse. Here again, we have good scientific ground for forgetting and ignoring those unhappy experiences from the past and concentrating upon the happy and pleasant. These concepts have developed not from wild specula- tion, a weird mumbo-jumbo about mentally constructed straw men such as the "Id," "Super-Ego" and the like, but from sound scientific research into brain physiology. They go a long way toward restoring the dignity of man as a responsible child of God, able to cope with his past and plan his future, as opposed to the image of man as helpless, victim of his past experiences. No longer can you derive sickly comfort from blaming your parents, society, your early experiences, or the in- justices of "others" for your present troubles. Blaming them, or even yourself for the past mis- takes, however, will not solve your problem, or improve your present or your future. Like a broken phonograph, you can keep on play- ing the same old "broken record" of the past; reliving past injustices; pitying yourself for past mistakes; all of which reactivates failure patterns and failure feelings which color your present and your future. Or, if you choose, you can put on a new record, and reactivate success patterns and "that winning feeling" which help you do better in the present and promise a more enjoyable future. Use the same technique on the "music" that comes out of your own internal machine. But it is not only possible, but I believe practical, to draw certain conclusions and implications from what is already known. In this chapter I would like to tell you some of the things that I believe and which have been of practical value to me. William James once said that everyone, scientists in- cluded, develops his own "over-beliefs" concerning (known facts, which the facts themselves do not justify. As a practical measure, these "over-beliefs" are not only [permissible, but necessary. Our assumption of a future goal, which sometimes we cannot see, is what dictates our present actions, and our "practical conduct. Otherwise he would not have sailed at all—or having sailed, would not have known whether to set his course to the south, east, north or west. Research experiments are not helter-skelter or aimless, but directed and goal oriented. In this last chapter I want to share with you some of my own over-beliefs, hypotheses, and philosophy, not as an M. Hans Selye has said, there are certain "truths" which cannot be used by medicine, but can be used by the patient. Life Force—The Secret of Healing and the Secret of Youth I believe that the physical body, including the physical brain and nervous system, is a machine, composed of numerous smaller mechanisms, all purposeful, or goal directed. Man him- self is not the machine, any more than electricity is the wire over which it flows, or the motor which it turns. Rhine calls "extra-physical"—his life, or vitality; his conscious- ness; his intelligence and sense of identity; that which he calls "I. It was also fairly obvious that the source of this basic energy—• whatever it might be—was something other than the "sur- face energy" we obtain from the food we eat. Hadfield wrote, "It is true that we do store up a certain amount of energy derived physiologically, from the nutriment of food and air. Whether we are to look upon this impulse as cosmic energy, as a life force, or what may be its relation to the Divine immanence in Nature, it is for other investigators to say. Selye has proved the existence bf a basic life force which he calls "adaptation energy. Selye has found that the human body contains various defense mechanisms (local adaptation syndromes or L. Selye, "has been coined for that which is consumed during contin- ued adaptive work, to indicate that it is something differ- ent from the caloric energy we receive from food, but this is only a name, and we still have no precise con- cept of what this energy might be. Further research along these lines would seem to hold great promise, since here we appear to touch upon the fundamentals of aging. Selye has written twelve books and hundreds of articles explaining his clinical studies and his "stress con- cept" of health and disease. Suffice it to say that his findings are recognized by medical experts the world over. And if you wish to learn more of the work which led to his findings, I suggest that you read Dr. Selye has proved is that the body itself is equipped to maintain it- self in health; to cure itself of disease, and to remain youthful by successfully coping with those factors which bring about what we call "old age. This elan vital, life force, or adaptation energy—call it whatever you will—manifests itself in many ways. The energy which heals a wound is the same energy which keeps all our other body organs functioning. When this energy is at an optimum all our organs function better, we "feel good," wounds heal faster, we are more "resis- tant" to disease, we recover from any sort of stress faster, ; we feel and act "younger," and in fact biologically we are younger. It is thus possible to correlate the various mani- festations of this life force, and to assume that whatever works to make more of this life force available to us; whatever opens to us a greater influx of "life stuff"; what- ever helps us utilize it better—literally helps us "all over. Whatever nonspecific therapy helps us over- come aches and pains, might, for example, improve eye- i sight. And this is precisely the direction which medical research is now taking and which appears most promis- ing. These "new" and "young" cells are then made into a tissue extract and injected into the patient. If the liver is malfunctioning, embryonic animal liver cells are used; if the kidneys are ailing, kidney tissue is used, etc. Although no one knows just why, there can be no doubt that some rather startling cures have been obtained. The theory is that these "young" cells somehow bring new life to the ailing human organ. Selye describes con- nective tissue as the "cement" which holds the body cells together and connects the various cells of the body with each other. Such an approach would, indeed, serve as a check against the aging process itself, keeping the individual at a younger age level by checking the rate of loss of his general resistance. It has been found to be much more active, for ex- ample, during infection, when the body needs additional defense. It has long been known that the body reacts rather violently, and quite often death results, from the injection of foreign pro- teins.

Oropharyngeal tumors may be painful, ulcerative and infiltrative but rarely metastasize. Clinical signs may include dysphagia, regurgitation, vomiting, diarrhea, tenesmus and cloacal prolapse. Prognosis depends on the location of the tumor, the degree of tissue infiltration and the occurence of metastasis. Many connective tissue tumors in gallinaceous birds may be caused by the leucosis sarcoma group of viral infections. Intestinal tumors must be differentiated from metastatic oviductal or ovarian tumors by demonstrating that no primary tumors of these organs exist and that the tumor originates from intestinal mucosal epithelium or glands, rather than growing inward from the serosal surface. In the emu and cassowary, a yolk sac can be palpated for at least one week, but it should be reduced in size.

If blankets, warm fuids, forced air blanket not used, patients cardiac rhythm changes to ventricular fbrillation that does not respond to medications and/ or defbrillation c. Aggressive rewarm- ing is necessary as well as early intubation for airway protection. It is critical to recognize the potential for hypothermia in cold-water immersion cases. Critical early actions include airway management, complete undressing of patient to avoid immersion syndrome, placement of rectal probe for constant temperature monitoring, aggressive rewarming techniques. Because the circumstances are unclear, the candidate should consider potential head and neck injury. In hypothermic patients, axillary and tympanic temperatures are often unreli- able. Rectal probe should be used for constant and accurate temperature moni- toring in these patients. Moderate hypothermia (between 30˚C and 34˚C) can present with loss of the shivering refex, mild alteration in consciousness, bradycardia, and atrial fbrillation. Patients with severe hypothermia (at temperatures below 30˚C) can present with fxed, dilated pupils, diminished refexes, coma, ventricular fbrillation, asytole. Attempts at defbrillation are usually unsuccessful at temperatures less than 30˚C. Core rewarming (dialysis, cardiopulmonary bypass, thoracic cavity lavage) should be reserved for patients with severe cardiovascular instability (cardiac arrest, ventricular fbrillation). In milder cases of hypothermia, warm blankets, forced air blankets (such as Bair Hugger), and warm fuids are usually suffcient to safely rewarm the patient.

This is a condition where there is an abnormal development of the aorta, the large vessel supplying blood to the body from the heart, which results in decreased blood fow to the lower body. In our patient the symptoms have become more prominent in the sec- ond week of life as the ductus arteriosus closes. Labs generally are not helpful in the diagnosis of aortic coarc- tation, but can be used to rule out sepsis and to see if the patient is acidotic. Cyanosis, dyspnea, or diaphoresis during feeding can be a sign of a congenital heart defect.

Viruses most commonly cause gastroenteritis leading to diarrhea but in this patient because the diarrhea. However, the bloody diarrhea in this case is suggestive of an inva- sive bacterial etiology. History of travel, antibiotic use, known sick contacts, or ingestion of contaminated food during an outbreak are also suggestive of bacterial infection. Infectious diarrhea is usually self-limiting and does not require antimicrobial therapy except in severe cases, including bloody diarrhea or duration greater than 3 days. Culture should also be sent in children, toxic patients, immunocompromised patients, or patients with history of travel. Typical viruses causing diarrhea are rotavirus, adenovirus, calicivirus, astro- virus, and Norwalk virus. Viruses typically affect the small intestine and do not present with bloody diarrhea. Thrombotic-thrombocytopenic purpura and hemolytic-urenic syndrome is a complication of infectious diarrhea, usually caused by E coli 0157:H7, and should be considered in children presenting with grossly bloody stool and olig- uria or anuria. In a patient presenting with bloody diarrhea, other conditions that should be considered include diverticulitis, mesenteric ischemia, gastrointestinal hemor- rhage, and infammatory bowel disease.
The insulin response to carbohydrate-containing foods is similar to the rise in blood sugar cheap tadalafil online visa erectile dysfunction caused by lack of sleep. The glycemic index is often used as a guideline for dietary recommendations for people with either diabetes or hypoglycemia discount 10 mg tadalafil with amex erectile dysfunction doctor in patna. In addition, eating foods with a lower glycemic index is associated with a reduced risk for obesity and diabetes. Obviously, quantity matters too, but the measurement of a food’s glycemic index is not related to portion size. The glycemic load takes the glycemic index into account but provides much more accurate information than the glycemic index alone. The glycemic load is calculated by multiplying the amount of carbohydrate in a serving of food by that food’s glycemic index, then dividing it by 100. In Appendix B, we provide the glycemic index and glycemic load for many common foods. Research studies are just starting to use glycemic load as a more sensitive marker for the role of diet in chronic diseases such as diabetes and heart disease. Preliminary results are showing that the glycemic load of a person’s food intake is a stronger predictor of diabetes than glycemic index. The Importance of Dietary Fiber in Reducing the Risk of Diabetes Population studies, as well as clinical and experimental data, show diabetes to be one of the diseases most clearly related to inadequate dietary ﬁber intake. The type of ﬁber that exerts the most beneﬁcial effects on blood sugar control is the soluble form. Included in this class are hemicelluloses, mucilages, gums, and pectin substances. These are capable of slowing down the digestion and absorption of carbohydrates, thereby preventing rapid rises in blood sugar. They are also associated with increasing the sensitivity of tissues to insulin and improving the uptake of glucose by the muscles, liver, and other tissues, thereby preventing a sustained elevation of blood sugar. Although even the simple change from white-ﬂour products to whole-grain versions is associated with a reduced risk for type 2,56,57 our recommendation is to consume at least 35 g ﬁber a day from various food sources, especially vegetables. Fiber supplements can also be taken to help lower the glycemic load of a food or meal. The Wrong Types of Fats Dietary fat plays a central role in the likelihood of developing type 2. Large controlled trials have shown that a reduction of fat intake as part of a healthful lifestyle, combined with weight reduction and exercise, reduces the risk of type 2. One of the key factors behind this linkage is the fact that dietary fat determines cell membrane composition. High consumption of saturated and trans fats leads to reduced membrane ﬂuidity, which in turn decreases the binding of insulin to receptors on cellular membranes, decreases insulin action, or both. Trans-fatty acids, found in margarine, shortening, and other foods that are made with partially hydrogenated vegetable oils, are particularly problematic, as they interfere with the body’s ability to use important essential fatty acids. One study estimated that substituting polyunsaturated vegetable oils for margarine would reduce the likelihood of developing type 2 by 40%. Studies have shown that consumption of nuts is inversely associated with risk of type 2, independent of known risk factors for type 2 such as age, obesity, family history of diabetes, physical activity, smoking, and other dietary factors. Higher intakes of ﬁber, magnesium, and foods with a low glycemic index have been associated with reduced risk of type 2 in several population-based studies. Low Intake of Antioxidant Nutrients Cumulative free radical damage leads to cellular aging and is a major factor contributing to type 2, as well as many other chronic degenerative diseases. Several large population-based studies have shown that the higher the intake of fruit and vegetables, the better blood glucose levels are controlled and the lower the risk for type 2. Fruits and vegetables are good sources of ﬁber, have a high nutrient content, and contain high levels of antioxidants. Even something as simple as regular salad consumption is associated with a reduced risk for type 2. What researchers found was that a low vitamin E concentration was associated with a 390% increase in risk of type 2. In addition to their ability to directly inﬂict damage on these structures, reactive oxygen and nitrogen species indirectly induce damage to tissues by activating a number of inﬂammatory compounds that ultimately lead to both insulin resistance and impaired insulin secretion. That fact has not dissuaded drug companies from developing drugs to do the same thing. However, the degree of prevention available from drugs pales in comparison with the effectiveness of diet and lifestyle. For example, in one of the most celebrated studies 3,234 subjects with impaired glucose tolerance (prediabetes) were randomly assigned to either a placebo, the blood-glucose- lowering drug metformin (850 mg twice per day), or a lifestyle modiﬁcation program, with the goals of at least a 7% weight loss and at least 150 minutes of physical activity per week. Compared with the placebo, the lifestyle intervention reduced the incidence of diabetes by 58%, and metformin reduced it by 31%. Clearly the lifestyle intervention was significantly more effective than metformin—a drug with sometimes serious side effects. Reducing chemical exposure by choosing organic food when possible, by using natural cleaners at home, and by not using chemical pesticides is a valid step to help prevent environmental toxins from negatively affecting insulin regulation in the body. Clinical Monitoring Knowledge and awareness are the greatest allies for people with diabetes. An individual with diabetes who makes a strong commitment to learning about his or her condition and who accepts the lead role in a carefully supervised monitoring program greatly improves the likelihood of living a long and healthy life. On the other hand, individuals who remain blissfully ignorant about their disease and who refuse to undergo regular testing or self-monitoring are far more likely to face years of unnecessary suffering and, more often than not, catastrophic health problems. Diabetes can be viewed as a state of biochemical and hormonal anarchy that, unless properly managed and supervised, will lead to organ injury and accelerated aging. Many of the complex control systems that faithfully govern and protect the body are damaged in the diabetic. In order to regain control, a diabetic must learn how to maintain intimate awareness of blood sugar levels, risk factors for atherosclerosis (hardening of the arteries), blood pressure, body mass index, level of ﬁtness, and other factors that determine the risk of developing diabetic complications and eroding quality of life. Fortunately, diabetics who do pay attention to these risk factors through regular testing and a properly supervised self-monitoring program are also those who are much more likely to beneﬁt from changes in lifestyle and diet, supplements, and, when necessary, medications. Self-Monitoring of Blood Glucose Levels Since its introduction, self-monitoring of blood glucose has revolutionized the management of diabetes. Diabetics who do not remain aware of their blood glucose and who do not make every effort to keep their blood sugar under tight control can expect a signiﬁcant increase in their risk of serious health problems such as eye, kidney, and heart disease, as well as a number of other problems such as depression, fatigue, impotence, and chronic infections. Self-monitoring of blood glucose is important for various reasons:79 • Modifications of treatment to achieve appropriate blood glucose control • Detection and diagnosis of hypoglycemia • The ability to adjust care in response to shifts in daily life circumstances (e. In the absence of diabetes, the pancreas monitors blood glucose continuously and adjusts its insulin output moment by moment in response to changes in blood glucose. In order to achieve blood glucose levels that are consistently as close to normal as possible, type 1 diabetics must replicate this natural function as closely as possible. This means that they need to monitor their blood glucose frequently, and they must learn to use this information to make ongoing adjustments to their insulin injections, diet, and exercise. Intensive insulin therapy allows a diabetic to achieve near-normal levels of blood glucose while enjoying improved lifestyle ﬂexibility. With conventional, infrequent insulin injections, the diabetic must structure meals and other aspects of lifestyle around these injections or face serious abnormalities of blood glucose.
The first is non- specific and can be applied for any product designed for routine use purchase tadalafil now erectile dysfunction zoloft, irrespective of the context order on line tadalafil erectile dysfunction killing me. The second approach is more spe- cific, evaluating individual devices in a particular context of use in order to focus on user-related and context-related ele- ments (2). For the purposes of this discus- sion, we shall use the term assistive devices to include a broad spectrum of medical de- vices, e. We shall not consider devices specifically used for reha- bilitation or retraining purposes (although evaluation of such devices shares common features with that of assistive devices, their use is direct- ly related to the recovery process). For interventions affecting the envi- ronment interacting with the disabled person, we shall limit our discus- sion to medical devices. Theoretically, the procedures used to evaluate assistive technology de- vices should be the same as those used to evaluate drugs, considering medical devices and drugs as members of a common family of medical in- terventions. In practice however, the specific features of assistive devices, particularly the important component of subjective appreciation, require specific evaluation protocols. The first phase occurs during development and early trials; at this level, the aim is to obtain administrative approval and determine optimal prescrip- tion. Once the device has been marketed, continuing surveillance is es- sential to watch for unexpected adverse effects and if needed to re-exam- ine initial indications. The main purpose of this second phase of evalua- tion is to verify the pertinence of individual prescriptions and assist deci- sion making. These evaluations can concern either the device itself or its use by a given individual or group of individuals. As for any manufactured product, an assistive device must meet pre-established production stan- dards. Certain standards result from mandatory regulatory criteria de- signed to protect users; others are established by the designer and the manufacturer and depend on the functional objectives assigned to the de- vice. It use depends on indications, contraindications and precautions, describing the rules and limitations of use. Technical specifications Compliance with regulatory standards, promulgated by the official authorities of the country of use, must be verified (4). Complementary specifications, particularly industrial protection spec- ifications, may be applicable in distinct geographical areas. The device and/or its constitutive elements are submitted to tests conducted by au- thorized laboratories to determine physical properties (resistance, ro- bustness…) and compliance with standard or chosen specifications. Cer- tain countries have mandatory approval procedures and some medical de- vices, depending on their potential class of use, require approval by inde- pendent organisms1 for marketing or reimbursement eligibility. Device watch programs, which register incidents or accidents occurring during use, constitute an a posteriori evaluation. Satellite services A specific environment, which may have an impact on user accep- tance, can be described for each assistive technology device. Product de- sign, industrial production, distribution networks, product diffusion, at- tribution services, product appearance, all contribute to this environment (5, 6). They affect the conditions of maintenance and repair (distribution network), product robustness, capacity for evolution, modularity and uni- versality, design and esthetic, as well as modalities of use, and have an im- pact on the lifespan of the product. Assistive technology services (coun- seling, consumer-directed personal assistance device, agency-directed personal assistance device, rehabilitation center, trial center…) (7) con- tribute to device acceptance and proper use. This subjective judgment affects the evaluation process, which must determine the ability of the assistive device-user cou- ple to perform tasks which otherwise could not have been achieved (de- vice efficacy or efficiency), assess modalities of task execution (operative quality), and examine use of the assistive device in real-life situations (ac- ceptability). Irrespective of its technological proper- ties, the device must first and foremost provide real assistance for activi- ties of daily life. If this crucial condition is not fulfilled, the device will be abandoned rapidly, a situation which is not exceptional and which can be a useful evaluation parameter (8, 9). Comparison between expected and real perfor- mance is the best way to evaluate functional efficacy. Since performance depends both on the device itself and on the user, the goal is to achieve con- cordance between device performance and user expectations. Evaluating a given device employed by a given user in a given clinical situation enables distinction between individual-related and context-related parameters. Difficulties en- countered during use, and the corresponding circumstances or specific limitations, particularly discomfort or problems with associated tasks, can be recognized. The second objective is to establish formal indications, con- traindications, precautions for use, risks, surveillance procedures, and lim- its of device efficacy. This requires a collective approach where individual trials are considered together. Data acquired from individual and collective trials are mandatory to obtain marketing approval and determine appro- priate prescription (10) as well as eligibility for institutional or organiza- tional funding. The way a device is used must be carefully analyzed so as to ensure that the energy output or specific movements or postures re- quired to use the device do not have short- or long-term pathogenic effects. Even if appropriate, an assistive device will not be used regularly for a prolonged period if it is not accepted by the user. Acceptability, a mea- surement of the way technical assistance is employed in everyday life, is re- lated to how well the user tolerates the constraints and discomfort imposed by the device. Ease-of-use (after appropriate learning and/or training, which implies accessibility to the learning process), ergonomics (3, 11) (en- ergy output and fatigue (12, 13), weight, volume, simplicity, command in- terface…), and device availability (anywhere, any time), reliability, and in- tercompatibility (combined use with other assistive technologies) as well as appropriation by the user and family or caregivers, are essential factors. The esthetic aspect of the device vehicles a specific image of technological assistance affecting both the user’s self-image and the regard of others. The device should not focus attention on the user’s disability (principle of trans- parence) and should have a favorable effect on the user’s image (e. The way a user personalizes the device, adapting it to changing body morphology, physical capacity (disease progression, aging), and lifestyle, greatly affects compliance and acceptability. In other words, the question is whether the “device compensates for the initial disability”. Is there adequate correspondence between the assistive device and user’s capacities and activity project in the context(s) in which the project is to be accomplished? Another domain to evaluate is the user’s self-assessment of the quali- ty of the compensation, i. The efficiency of a given device may in itself generate effects having a neg- ative impact on its acceptability. The user’s early enthusiasm may wear off, sometimes rapidly, particularly when the device compensates for an artificial activity. Like the placebo effect, it takes at least three months for this effect to dissipate. Determined by the user who has re- ceived appropriate counseling and information, the activity project must be realistic. Likewise, the proposed technical assistance (one or more devices, possible adaptation of the environment) must be rea- sonably expected to be effective. The level of the user’s motivation must also be assessed to determine the degree of impli- cation. It is thus desirable to conduct trials in real-life or simulated situations (15) in order to as- sess the impact on the activities requiring compensation. They involve anthropo- logical features (body integrity, pain, mobility, sensorial status, func- tional abilities, installation and positioning in bed or wheel chair), cognitive features (intellectual capacity, schooling, occupational ac- tivity), and behavioral and lifestyle features (personal appearance, so- ciability, role, familial and social activities).
