[Exercise and physical therapy in osteoporosis].

Initial studies demonstrated that an adequate amount of continuous exercise such as weight-bearing and aerobic training slow down bone loss, maintain bone mineral density, or even increase bone density in the young adulthood though the magnitude of mechanical loading of the bone. However, it remains unclear whether physical activity is also beneficial for bone health in postmenopausal and elderly women with osteoporosis whose exercise endurance capacity is commonly decreased. Recent longitudinal studies showed that 1-2 years of moderate to intensive exercise can increase postmenopausal bone mass, although the amounts of bone gain are relatively modest and site-specific. Thus, weightbearing exercise should be recommended not only to inhibit loss of bone mass but also to increase muscle strength in the elderly, which definitely lead to prevention of falls and decrease the incidence of new fractures.

Rheumatologist-patient communication about exercise and physical therapy in the management of rheumatoid arthritis.

OBJECTIVE: Little is known about the features and role of exercise discussions between rheumatologists and patients. The goals of this study were to: 1) describe rheumatologists' and patients' attitudes and beliefs regarding exercise and physical therapy for rheumatoid arthritis (RA); 2) describe frequency and length of exercise discussions; 3) determine the accuracy of recall for exercise discussions; and 4) assess the influence of attitudes regarding exercise on communication about exercise. METHODS: Goals 1-3 were addressed with analysis of baseline questionnaires and audiotaped encounters. The influence of attitudes and beliefs regarding exercise on the frequency and length of exercise discussions was assessed prospectively. Patients and rheumatologists were enrolled from a large tertiary care institution. Clinical encounters were audiotaped, transcribed, coded, and analyzed to identify specific characteristics of the exercise discussions. RESULTS: One hundred thirty-two patients and 25 rheumatologists participated in the study. Rheumatologists and patients discussed exercise in 53% of the encounters. Rheumatologists' beliefs regarding the usefulness of exercise for RA varied, with the least positive beliefs being reported for aerobic exercise. Exercise discussions were more likely to occur if the patient was currently exercising, odds ratio (OR) = 2.4; 95% confidence interval (CI) (1.2-4.9), and when the rheumatologist believed aerobic exercises were useful in managing RA, OR = 1.4; 95% CI (1.1-1.9). Current exercise behavior was associated with patients' positive attitude toward exercise (chi 2 1 = 8.4; P = 0.004) and perceived social support for exercise (chi 2 1 = 4.5; P = 0.04). When rheumatologists initiated exercise discussions, there was nearly twice as much discussion (beta = -8.4; P = 0.001). CONCLUSIONS: Exercise talk was influenced by patients' and rheumatologists' beliefs and attitudes regarding the effectiveness of exercise and physical therapy in managing RA, patient experience with exercise, and by characteristics of the rheumatologist.

Medical assessment for health advocacy and practical strategies for exercise initiation.

The universal caution to consult your family doctor before beginning an exercise program creates an image of exercise as potentially harmful. Moreover, insistence on extensive screening prior to exercise is both unrealistic and often inappropriate for the older adult. Recasting the role of the physician as a physical activity advocate rather than as a gatekeeper is recommended for incorporation into guidelines for exercise screening. A geriatric assessment focusing on identification of specific parameters predictive of disablement risk can be incorporated into the exercise prescription as a guide for initiating exercise. The purpose of this article is to: (1). review the role of the primary care physician in screening and advocating exercise; (2). examine objectively the risk of exercise among older adults and place these risks in context with current screening guidelines with a particular emphasis on the exercise test; and (3). examine how key concepts derived from epidemiologic studies of disability can be distilled into practical guidelines for exercise therapy. We provide an overview of relevant literature related to screening and initiating exercise. Key challenges are highlighted and discussed. Suggestions for changes in policy are recommended. Given the apparent discordance between screening guidelines for the older adult and risk of adverse events, and between existing recommendations for physical activity and epidemiologic studies of disability, an evidence-based approach is recommended to review and revise screening and prescribing practices.

Relationship between estimated body fat and some respiratory function indices.

OBJECTIVE: To find the relationship between estimated body fat and respiratory function indices. DESIGN: Cross sectional study of volunteers in the physiotherapy department. SUBJECTS: Physiotherapy patients with no respiratory or neuromascular diseases. MAIN OUTCOME MEASURES: Quetelet index (as measure of body fat), vital capacity and breath holding time. RESULTS: Their ages ranged from 20 year to 60 years with a mean 24.20 +/- 6.59 years and 29.72 +/- 14.18 years in males and females respectively. Subjects whose quetelet index was about 30 kg/m2 and above were classified as obese. None of the male subjects fell into the obese category, while six of the 50 female subjects fell into the obese category. Significant differences were observed in the mean of the Quetelet index, percent predicted vital capacity and the breath holding time between the normal female and the obese female subjects. A high but inverse relationship was found between estimated body fat and each percent predicted vital capacity and breath holding time in subjects whose Quetelet index was above 30 kg/m2. There was also a high and positive correlation between percent predicted vital capacity and breath holding time in subjects with Quetelet index above 30 kg/m2. CONCLUSION: These findings were attributed to the restrictive effect of excess adipose tissue located around the thorax and the abdomen. It was concluded that adequate caution should be taken during exercise therapy for patients with a Quetelet index value above 30 kg/m2 to enable them exercise safely and with respiratory efficiency.

The metabolically obese, normal-weight individual revisited.

Nearly 20 years ago, it was suggested that individuals exist who are not obese on the basis of height and weight, but who, like people with overt obesity, are hyperinsulinemic, insulin-resistant, and predisposed to type 2 diabetes, hypertriglyceridemia, and premature coronary heart disease. Since then it has become increasingly clear that such metabolically obese, normal-weight (MONW) individuals are very common in the general population and that they probably represent one end of the spectrum of people with the insulin resistance syndrome. Available evidence also suggests that MONW individuals could account for the higher prevalence of type 2 diabetes, cardiovascular disease, and other disorders in people with a BMI in the 20-27 kg/m2 range who have gained modest amounts of weight (2-10 kg of adipose mass) in adult life. Specific factors that appear to predispose MONW, as well as more obese individuals, to insulin resistance include central fat distribution, inactivity, and a low VO2max. Because these factors are potentially reversible and because insulin resistance may contribute to the pathogenesis of many diseases, it is our premise that a compelling argument can be made for identifying MONW individuals and treating them with diet, exercise, and possibly pharmacological agents before these diseases become overt, or at least early after their onset. One reason for doing so is that disorders such as type 2 diabetes may be accompanied by irreversible consequences, e.g., ischemic heart disease and nephropathy, at the time of diagnosis or shortly thereafter. Another is that MONW individuals in general should be younger and more amenable and responsive to diet and exercise therapy than are obese patients with established disease. That long-term diet and exercise can work is suggested by two large studies in which, over 5-6 years, the incidence of diabetes was diminished in nonobese and minimally obese patients with impaired glucose tolerance. Based on these considerations and the emerging worldwide epidemic of type 2 diabetes, we believe that studies to assess whether therapies aimed at young MONW individuals can prevent the development of type 2 diabetes and other diseases, including perhaps obesity itself, are urgently needed.

Testosterone therapy and the pathogenesis of Kennedy's disease (X-linked bulbospinal muscular atrophy).

The mutation in X-linked bulbospinal muscular atrophy (XBSMA) is an increased CAG triplet repeat coding for a polyglutamine domain in the gene for the androgen receptor. This might impair the effect of testosterone on motor neurons, leading to their progressive degeneration. We report a trial of high-dose oral testosterone therapy in two brothers with XBSMA. Patient 1 received 37.5 mg of testosterone daily for more than 18 months, and Patient 2 received 25 mg per day for six months, both in combination with exercise therapy. Patient 1 showed improvement of up to 300% in muscle work output. Patient 2, who did less exercise, had no symptomatic improvement. These results indicate that exogenous testosterone therapy is not harmful, and may produce functional improvement when combined with exercise. We hypothesize that high-dose testosterone may reduce a toxic gain of function that the mutation produces, perhaps by inhibiting glutamate neurotoxicity.

Progressive resistance exercise in physical therapy: a summary of systematic reviews.

Progressive resistance exercise (PRE) is a method of increasing the ability of muscles to generate force. However, the effectiveness and safety of PRE for clients of physical therapists are not well known. The purpose of this article is to review the evidence on positive and negative effects of PRE as a physical therapy intervention. Electronic databases were searched for systematic reviews on PRE and any relevant randomized trials published after the last available review. The search yielded 18 systematic reviews under major areas of physical therapy: cardiopulmonary, musculoskeletal, neuromuscular, and gerontology. Across conditions, PRE was shown to improve the ability to generate force, with moderate to large effect sizes that may carry over into an improved ability to perform daily activities. Further research is needed to determine the potential negative effects of PRE, how to maximize carryover into everyday activities, and what effect, if any, PRE has on societal participation.

Exercise testing in patients with musculoskeletal handicaps.

To determine safe and effective exercise testing techniques for musculoskeletally handicapped individuals, 20 patients (mean age, 61 years) were studied. Types of handicaps included various degrees of paralysis of arms and legs, and leg amputations. Seventeen of the 20 patients had concurrent cardiovascular problems. All were currently hospitalized, engaged in various physical therapy exercises, and referred for exercise testing to increase rehabilitation therapy or for cardiovascular evaluation. Of 20 tests, arm ergometry was used in 15, leg or combination arm-leg ergometry in four, and treadmill in one. All patients completed testing with mean increases in heart rate (82 to 106 bpm arm, 88 to 125 other) and systolic blood pressure (114 to 127 mmHg arm, 118 to 146 other). Low-grade atrial and ventricular ectopy occurred in eight patients, decrease or plateauing of systolic blood pressure in three, increased diastolic blood pressure in two, and significant (greater than or equal to 1mm) ECG S-T segment displacement in one. With the use of appropriate equipment for each patient, exercise testing can be done safely and effectively in musculoskeletally handicapped individuals.

Nitrate tolerance.

The organic nitrates are the most widely used agents in the management of patients with angina pectoris. When initially administered by the oral route, the nitrates produce profound changes in systemic hemodynamics and significant and prolonged improvement in exercise duration. It has been shown that during short periods of regular oral nitrate administration, the hemodynamic, antiischemic and antianginal effects of the nitrates are greatly reduced. Thus, when initially administered, oral isosorbide dinitrate prolongs exercise duration for a period of several hours, but during sustained 4-times-daily therapy, exercise tolerance is improved for only 2 hours after administration. Studies with transdermal preparations of isosorbide dinitrate and nitroglycerin also show improvement during short-term administration for up to 8 hours, but after several days of once-daily therapy, the effects of these agents are similar to placebo. It is apparent that nitrate tolerance is a clinically relevant problem. Although tolerance develops rapidly during nitrate therapy, it is reversed promptly during nitrate-free periods. Oral nitrates maintain their antianginal effects when given 2 or 3 times daily with provision of a nitrate-free period. Studies are currently underway to investigate the effects of intermittent administration schedules with transdermal nitrate preparations.

[Effect of exercise as a therapy for osteoporosis on bone metabolism].

Exercise affects bone mass most effectively in adolescence depending its property. For postmenopausal women, resistance or high-impact loading training are suggested as preventative exercise against bone loss at the femoral neck. Physical exercise affects the balance of bone turnover. However, there is the discrepancy between studies on bone metabolic markers at present. In my opinion, the proper evaluation of exercise for osteoporosis should focus on prevention of falls.

Manual physical therapy interventions and exercise for patients with temporomandibular disorders.

The purpose of this study was to investigate the outcome of a series of consecutive patients with temporomandibular disorder (TMD) who were treated with manual physical therapy interventions and exercise. Consecutive patients with the clinical presentation of TMD completed several self-report measures and underwent a standardized historical and physical examination. Following the examination, patients received a multimodal treatment approach incorporating manual physical therapy and exercise. All self-report questionnaires were completed at a 2-week follow-up. Paired t-tests were performed between the baseline and 2-week follow-up scores. The mean TMD Disability Index scores were 32.1% (15.4%) at baseline and 18.3% (12.5%) at the 2-week follow-up, representing an improvement of 13.9% (CI: 8.2%, 19.5%) (p < 0.05). Patient Specific Functional Scale (PSFS) scores improved 3.1 points (CI: 2.3, 3.9) (p < 0.05). These results suggest that patients with TMD who are treated with a rehabilitation program including manual physical therapy interventions plus exercise, with or without iontophoresis with dexamethasone, can demonstrate clinically meaningful improvements in disability and overall perceived change in a relatively short period of time.

Exercise and the treatment of clinical depression in adults: recent findings and future directions.

This article critically reviews the evidence that exercise is effective in treating depression in adults. Depression is recognised as a mood state, clinical syndrome and psychiatric condition, and traditional methods for assessing depression (e.g. standard interviews, questionnaires) are described. In order to place exercise therapy into context, more established methods for treating clinical depression are discussed. Observational (e.g. cross-sectional and correlational) and interventional studies of exercise are reviewed in healthy adults, those with comorbid medical conditions, and patients with major depression. Potential mechanisms by which exercise may reduce depression are described, and directions for future research in the area are suggested. The available evidence provides considerable support for the value of exercise in reducing depressive symptoms in both healthy and clinical populations. However, many studies have significant methodological limitations. Thus, more data from carefully conducted clinical trials are needed before exercise can be recommended as an alternative to more traditional, empirically validated pharmacological and behavioural therapies.

Post-Polio Syndrome.

Post-polio syndrome (PPS) is the term used for the new late manifestations that occur in patients 30 to 40 years after the occurrence of acute poliomyelitis. PPS has been recognized for over 100 years, but is more common at the present time because of the large epidemics of poliomyelitis in the 1940s and 1950s. PPS is manifested by neurologic, musculoskeletal, and general manifestations. Neurologic manifestations include new weakness, muscle atrophy, dysphagia, dysphonia, and respiratory failure. Musculoskeletal manifestations include muscle pain, joint pain, spinal spondylosis and scoliosis, and secondary root and peripheral nerve compression. General manifestations include generalized fatigue and cold intolerance. New muscle weakness of a mild-to-moderate degree responds well to a nonfatiguing exercise program and pacing of activity with rest periods to avoid muscle overuse. Generalized fatigue may be treated with energy conservation and weight loss programs and lower extremity orthoses. Pharmacologic agents also may be helpful, but have not been beneficial in controlled trials. Bulbar muscle weakness includes dysphagia, dysphonia, sleep disorders, and chronic respiratory failure. Dysphagia may be improved with instruction on compensatory swallowing techniques. Dysphonia is treated with voice exercise therapy and voice amplification devices. Sleep disorders are treated similarly to sleep disorders in non-PPS patients. Respiratory failure may be treated with continuous positive airway pressure, bilevel positive airway pressure, and nasal ventilation, or tracheotomy and permanent ventilation if necessary. Musculoskeletal (muscle and joint) pain is treated with weight loss, pacing of activities, use of assistive devices, and prescribing anti-inflammatory medications and physical therapy techniques. Cardiopulmonary conditioning can be improved without muscle overuse with cycle or arm ergometer exercise or dynamic aquatic exercise.

Complementary therapy use among older cancer patients.

PURPOSE: The purpose of this study was to assess the use of complementary therapies among older cancer patients, to report patterns of use, and to understand who is more likely to use complementary therapies. DESCRIPTION OF STUDY: A survey was conducted of 699 older cancer patients at 4 weeks and 6 weeks into cancer treatment. All participants were 64 years of age or older, had received a diagnosis of breast, colorectal, prostate, or lung cancer, and were recruited from community cancer treatment centers throughout Michigan. Measures of interest included self-reported physical symptoms, depressive symptomatology, optimism, spirituality, and use of conventional and complementary health services. RESULTS: Approximately 33% of older cancer patients reported using complementary therapies. These individuals were more likely to be women, to be breast cancer patients, and to have a higher level of education. The three most frequently used therapies were exercise, herbal therapy, and spiritual healing. Complementary therapy users were significantly more optimistic than nonusers. Also, there were significant differences between users and nonusers on types of physical symptoms experienced, but no differences on reported depressive symptomatology or spirituality. CLINICAL IMPLICATIONS: Oncology providers need to be aware that one third of their older patients are likely to supplement conventional care with complementary therapies. Therefore, providers should be knowledgeable about the safety and efficacy, in particular, of various exercise programs, herbal and vitamin therapies, and spiritual healing. It would be beneficial to develop a system within cancer centers by which patients could easily report on their use of complementary therapies, allowing providers to work in partnership with their patients.

Control of acceleration during sudden ankle supination in people with unstable ankles.

STUDY DESIGN: Comparative study of differences in functional control during ankle supination in the standing position in matched stable and unstable ankles (ex post facto design). OBJECTIVES: To document acceleration and deceleration during ankle supination in the standing position and to determine differences in control of supination perturbation between stable and unstable ankles. BACKGROUND: Repetitive ankle sprain can be explained by mechanical instability only in a minority of cases. Exercise therapy for ankle instability is based on clinical experience. Joint stability has not yet been measured in dynamic situations that are similar to the situations leading to a traumatic sprain. The process of motor control during accelerating ankle supination has not been adequately addressed in the literature. METHODS AND MEASURES: Patients with complaints of ankle instability (16 unstable ankles) and nonimpaired controls (18 stable ankles) were examined (N = 17 subjects, 10 women and 7 men). The average age was 23.7 +/- 5.0 years (range, 20-41 y). Control of supination speed was studied during 50 degrees of ankle supination in the standing position using accelerometry (total supination time and deceleration times) and electromyography (latency time). Timing of motor response was estimated by measuring electromechanical delay. RESULTS: The presence of an early, sudden, and presumably passive slowdown of ankle supination in the standing position was observed. Peroneal muscle motor response was detected before the end of the supination. Unstable ankles showed significantly shorter total supination time (109.3 ms versus 124.1 ms) and significantly longer latency time (58.9 ms versus 47.7 ms). CONCLUSIONS: Functional control in unstable ankles is less efficient in decelerating the ankle during the supination test procedures used in our study. Our conclusions are based on significantly faster total supination and significantly slower electromyogram response in unstable ankles. The results support the hypothesis that both decelerating the total supination movement during balance disturbance and enhancing the speed of evertor activation through exercise can be specific therapy goals.

Exercise and diabetes.

As rates of diabetes mellitus and obesity continue to increase, physical activity continues to be a fundamental form of therapy. Exercise influences several aspects of diabetes, including blood glucose concentrations, insulin action and cardiovascular risk factors. Blood glucose concentrations reflect the balance between skeletal muscle uptake and ambient concentrations of both insulin and counterinsulin hormones. Difficulties in predicting the relative impact of these factors can result in either hypoglycemia or hyperglycemia. Despite the variable impact of exercise on blood glucose, exercise consistently improves insulin action and several cardiovascular risk factors. Beyond the acute impact of physical activity, long-term exercise behaviors have been repeatedly associated with decreased rates of type 2 diabetes. While exercise produces many benefits, it is not without risks for patients with diabetes mellitus. In addition to hyperglycemia, from increased hepatic glucose production, insufficient insulin levels can foster ketogenesis from excess concentrations of fatty acids. At the opposite end of the glucose spectrum, hypoglycemia can result from excess glucose uptake due to either increased insulin concentrations, enhanced insulin action or impaired carbohydrate absorption. To decrease the risk for hypoglycemia, insulin doses should be reduced prior to exercise, although some insulin is typically still needed. Although precise risks of exercise on existing diabetic complications have not been well studied, it seems prudent to consider the potential to worsen nephropathy or retinopathy, or to precipitate musculoskeletal injuries. There is more substantive evidence that autonomic neuropathy may predispose patients to arrhythmias. Of clear concern, increased physical activity can precipitate a cardiac event in those with underlying CAD. Recognizing these risks can prompt actions to minimize their impact. Positive actions that are part of exercise programs for diabetic patients emphasize SMBG, foot care and cardiovascular functional assessment. SMBG provides critical information on the impact of exercise and is recommended for all patients before, during and after exercise. More frequent monitoring (and for longer periods following exercise) is recommended for those with hypoglycemia unawareness or those performing high-intensity exercise. Preventing the sequelae of an exercise-induced severe hypoglycemic reaction can be as simple as carrying glucose tablets or gel, a diabetic identification bracelet or card, or exercising with an individual who is aware of the circumstances. In addition to blood glucose concentrations, proper foot care is critical to people with diabetes who exercise and includes considering type of shoe, type of exercise, inspection of skin surfaces and appropriate evaluation and treatment of lesions (calluses and others). Those with severe neuropathy can consider alternatives to weight-bearing exercises. Precipitation of clinical CAD is of great concern for all diabetic patients participating in exercise activities. Although a sufficiently sensitive and specific screening test for coronary disease has not been identified, those planning an exercise program of moderate intensity or greater should be evaluated. Initial cardiac assessment should include exercise testing as well as identifying risk for autonomic neuropathy. In addition to noting maximal heart rate and blood pressure as well as ischemic changes, exercise tolerance testing can identify anginal thresholds and patients with asymptomatic ischemia. Those without symptoms should be counseled regarding target pulse rates to avoid inducing ischemia. Ischemic changes need to be evaluated for either further diagnostic testing or pharmacological intervention. For patients with diabetes mellitus, the overall benefits of exercise are clearly significant. Clinicians and patients must work together to maximize these benefits while minimizing risks for negative consequences. Identifying and preventing potential problems beforehand can reduce adverse outcomes and promote this important approach to healthy living.

[The use of thermal vibromassage of the chest cavity in patients with chronic obstructive bronchitis for improving their tolerance for physical loads].

According to the bicycle ergometry data the greater part of patients with chronic obstructive bronchitis are characterized by reduced physical work fitness. The latter one was found to rise under the effect of thermal vibromassage of the chest at a frequency of 30 Hz. The method has been elaborated and the advisability of its use has been theoretically based. The given method can be applied to the rehabilitation treatment of patients, particularly before exercise therapy.
