ADP and collagen induced platelet aggregation (PA) was studied in 18 patients suffering from arterial occlusive disease (stage II Fontaine) before and after a standardized treadmill test before and after 24 days of exercise training. At the beginning of this therapy collagen induced PA after treadmill testing was increased (amplitude +11.29%, p less than 0.05, maximal slope +18.57%, p less than 0.05, integrated area +15.23%, p less than 0.05), whereas ADP induced PA showed no consistent alteration. After the 24-day treatment period increase in collagen induced PA was considerably smaller (amplitude +7.48%, n.s., maximal slope +7.35%, n.s., integrated area +11.99%, p less than 0.05), whereas ADP induced PA again showed no consistent changes. Since the treadmill exercise induced PA showed a negative linear correlation with the claudication provoking walking distance the smaller increase in PA after treatment was considered to be due to the improved metabolic situation following exercise therapy.
BACKGROUND: 'Vestibular rehabilitation' (VR) is an increasingly popular treatment option for patients with persistent dizziness. Previous clinical trials have only evaluated the effects of specialist therapy programmes in small, selective, or uncontrolled patient samples. AIM: To determine the benefits of VR compared with standard medical care, using a brief intervention for dizzy patients in primary care. METHOD: Adults consulting their general practitioner (GP) with dizziness or vertigo were randomly assigned to treatment or control groups. Patients in both groups received the same evaluation at baseline, six-week follow-up, and six-month follow-up, comprising examination of nystagmus, postural control, and movement-provoked dizziness, and a questionnaire assessment of subjective status, symptoms, handicap, anxiety, and depression. At baseline and six weeks later, the treatment group also received an individualized 30-minute therapy session, in which they were taught head, eye, and body exercises designed to promote vestibular compensation and enhance skill and confidence in balance. RESULTS: The treatment group (n = 67) improved on all measures, whereas the control group (n = 76) showed no improvement, resulting in a significant difference between the two groups on physical indices of balance and subjective indices of symptoms and distress. Odds ratios for improvement in treated patients relative to untreated patients were 3.1:1 at six weeks (95% CI = 1.4-6.8) and 3.8:1 at six months (95% CI = 1.6-8.7). CONCLUSION: VR is a simple, inexpensive, and beneficial treatment, and may be an appropriate first stage of management for many dizzy patients in primary care.
OBJECTIVE: To define the effects of therapeutic exercise on bone density and back complaints. METHODS: A randomised controlled trial with parallel groups was conducted in an outpatient clinic, Medical School, University of Vienna. Ninety two sedentary post-menopausal women with back problems were randomly allocated to either exercise (groups 1 and 2) or control (group 3, no exercise, n = 31); the exercise group was retrospectively subdivided into compliant (group 1, n = 27) and not fully compliant patients (group 2, n = 34). Regular, initially supervised therapeutic exercise aimed at restoring biomechanical function was performed for four years. Bone density in the forearm was measured by single photon absorptiometry at entry and after four years; subjective back complaints were documented. RESULTS: A significant decrease in bone density was observed in groups 2 and 3; no change was noted in group 1; back complaints decreased in group 1 only. CONCLUSIONS: Sedentary postmenopausal women may benefit from regular long term therapeutic exercise in terms of subjective back complaints and slowed loss of bone mass.

Our experimental and clinical studies lead to the following conclusions: 1. The amount of exercise that has a favorable effect on bone tissue differs between males and females among individuals. 2. An appropriate amount of exercise has a favorable influence not only on weight-bearing bone but also on non-weight-bearing bone, provided there is a sufficient intake of calcium. 3. Exercise may prevent the bone loss in osteoporosis, but an increase in bone mass cannot be expected. The major aim is to increase bone mass before the achievement of peak bone mass in order to prevent osteoporosis. However, suitable weight-bearing exercise in osteoporosis is useful for the prevention of falls which may result in fractures, to increase muscle strength, to improve walking balance and coordination, and to prevent orthostatic hypotension.
Direct and remote effects of therapeutic exercises on the low-back pain syndrome in cotton-industry workers have been estimated. The treatment was applied to fifty-five patients aged from 30 to 58 (mean age--45) with chronic pain-syndrome, who were submitted to a series of exercises and everyday gymnastics. In the course of treatment the following results were obtained: retreatment of low-back pains, increasing of spines mobility (activity), increasing of abdomen-muscle strength. One-year follow-up demonstrated sickness absenteeism decrease by 66%, as compared to a period of the same duration prior to treatment.
