No benefit of bracing on the early outcome after anterior cruciate ligament reconstruction.

Forty patients were prospectively investigated to evaluate the effects of bandaging after reconstructive surgery of the anterior cruciate ligament (ACL). For the 6 weeks of the postoperative course, the operated knee was bandaged in 20 patients (group A) and braced in the other 20 patients (group B). The isokinetic torque for extension and flexion (Cybex) and the range of motion (ROM) were investigated after 6, 12, 24 and 52 weeks postoperatively. At 24 weeks and 1 year postoperatively the stability of the knee joint (KT-1000) as well as the clinical outcome ('Orthopädische Arbeitsgemeinschaft Knie') were evaluated. No statistically significant differences between the two groups were found for the extension and flexion strengths. Free ROM was achieved significantly earlier in group A than in group B. No statistically significant differences regarding the stability of the operated knee joint nor the early outcome were found between the two groups. This study demonstrated that the renunciation of using a brace had no adverse effect on the early outcome with respect to stability and function. On the contrary, bracing seems not to be mandatory after ACL reconstruction when the central third of the patellar tendon is used.

Exercise therapy for osteoporosis: results of a randomised controlled trial.

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.

Forearm bone density and grip strength in women after menopause, with and without estrogen replacement therapy.

Peaking in young adulthood, both bone mass and muscle strength decrease with ageing, but bone loss may accelerate after the menopause and can be delayed by estrogen replacement therapy (ERT). This study was designed to evaluate whether, like bone density, the muscle strength was affected by the onset of menopause and/or ERT. First grip strength (GS) of young female adults (group III; n = 18; age (+/- S.E.M.) 21.8 +/- 0.4 years) was compared to that of postmenopausal women, who were divided into two groups. Group I (n = 22; age 59.6 +/- 1.6 years) was 12.5 +/- 1.7 years after the menopause and received no ERT, and group II (n = 21; age 59.5 +/- 1.1 years) was 8.3 +/- 1.2 years after the menopause and had received ERT for 3.9 +/- 2.3 years at the time of the study. GS of the postmenopausal women was significantly (P < 0.005) lower than that of the young female adults. GS did not differ significantly between both postmenopausal groups. Further analysis revealed a weak negative correlation of years since menopause with forearm bone density (r = -0.37, P < or = 0.023 for group II and III together), but not with GS. It is concluded that the later onset of menopause and estrogen replacement therapy do not seem to have a noticeable influence on muscle strength.

[Nutrition and osteoporosis: a nutritional analysis of women in postmenopause].

In a cross-sectional study the effects of several nutritional factors on the manifestations of osteoporosis were investigated in 23 postmenopausal women aged 50 to 70 years. Twelve women (group 1) with osteoporosis and eleven healthy control subjects (group 2) were instructed to keep a seven-day nutritional record. Body mass index (BMI) was recorded, and radiological and bone mineral density investigations were undertaken. The daily total energy, protein, fat, carbohydrate, fiber, oxalic acid, calcium, magnesium, phosphorus, sodium, fluoride, zinc, copper, manganese, vitamin C, D, and K intake were analysed within the framework of a nutritional science program. No intergroup differences were observed with regard to total energy intake, nutritional components and BMI; however, age and years since the menopause differed significantly (p < 0.05). The results suggest that the manifestation of osteoporosis in women is influenced to a greater extent by age and years since the menopause than by the distribution of nutritional factors in a normal mixed diet. However, further studies are essential to evaluate the role of dietary composition on the manifestations of osteoporosis.

Functional impact of unvarying exercise program in women after menopause.

Low bone mass, functional impairment, low muscle strength, and postural instability are predictors of the risk of fracture in an elderly person. The purpose of this study was to investigate the functional impact of an unvarying long-term exercise program to be carried out at home. The exercises had been shown to delay bone loss in an elderly population. At the Department of Physical Medicine and Rehabilitation, University of Vienna, postmenopausal women who had been stratified into exercise or control groups 5 to 10 yr ago were called in for a follow-up examination. Frequency of training, habits, and pain causing disability in activities of daily living were recorded. Walking velocity, muscle strength, and postural stability were measured. Functional assessment, blood analysis, and x-rays of the spine were performed additionally. One hundred twenty-four women aged 68.3 +/- 6.8 yr (mean +/- SD) underwent a follow-up investigation at the outpatient clinic. After 7.7 +/- 1.1 yr the compliance of the training group was still 36%. Self-chosen gait velocity was slightly higher in the regular exercisers than in the controls. No intergroup differences were found for pain induced disability, muscle strength, body sway, and fracture rate. The pain disability index was significantly associated with corrected self-chosen gait velocity. The results suggest that an unvarying home-based exercise program may support general agility but does not yield enough force to improve muscle strength and postural stability in healthy, nondisabled, postmenopausal women who start exercising at the age of 60 yr. Further studies are needed to define more appropriate exercise programs for a comprehensive improvement of functional outcome in a population at high risk for osteoporosis.

Therapeutic exercise in the prevention of bone loss. A controlled trial with women after menopause.

To evaluate the efficacy of therapeutic exercises in the prevention of bone loss, 146 untrained healthy postmenopausal women were prospectively controlled for (mean +/- SD) 3.0 +/- 1.3 yr. Eighty-two subjects aged (mean +/- SD) 61.5 +/- 6.1 yr participated in an exercise program (group 1) and sixty-four aged (mean +/- SD) 59.1 +/- 7.4 yr served as controls (group 2). Periodically during the study period, we measured women's bone density at two forearm sites and recorded their physical activities. Because bone loss differed insignificantly between the groups, group 1 was retrospectively subdivided into group 1a (regular exercise) and group 1b (nonregular exercise). The results showed that only 39 women (48 percent) of group 1 (group 1a) performed the exercise program regularly for the prescribed time. Regression slopes of forearm bone density (distal and proximal scans) v time were significantly less negative (P < 0.05) in group 1a (distal, -0.3 percent and proximal, -0.7 percent per year) than in group 1b (distal, -1.8 percent and proximal -1.6 percent per year) or group 2 (distal, -1.7 percent and proximal, -1.9 percent per year). We conclude that in untrained elderly women, poor compliance with regular physical activities is a main factor, explaining the lack of response to exercise treatment in prevention of osteoporosis.
