Neue Aspekte der physikalischen Therapie der Osteoporose

Fractures due to osteoporosis are among the leading causes of functional limitation, chronic pain, and greater morbidity in advanced age. Apart from bone, risk factors for osteoporotic fractures include non-osseous causes such as falls or reduced neuromuscular capacity. Muscle and coordination exercises enhance the patient’s abilities in daily life and prevent falls. In view of recent conclusions drawn from competitive sports, which stress the significance of muscles of the trunk with regard to reducing back pain and optimizing posture, we used sling exercises to determine whether they benefit patients with osteoporosis and are more useful than traditional physiotherapy. A stable ceiling construction was installed for sling exercise; slings were suspended from this construction. Fifty patients were randomized into two groups. Group A received traditional physiotherapy while group B was given sling exercises, in each case twice a week for a period of three months. The exercises were similar in the two groups. Both performed chair-rising exercises and pelvic lift in supine position; the sling exercise group used the slings for this purpose. The results of treatment (pre-post) were analyzed in terms of pain levels, mobility, trunk strength, and the shape of the back. For the latter we used the spine scanner Diers®Formetric 4D to measure the spine surface of the patients with low radiation. After a further three months with no specific exercise treatment, we re-tested the patients to establish the long-term effects of the two types of exercises. Forty-four patients (88 %) completed the study. Patients were assigned to small groups for the exercises (a maximum of 5 patients each), and thus received individual attention and motivation. Positive training effects were achieved in both groups. Significantly better results in regard of improved mobility (8.2 ± 1.9 vs. 6.7 ± 1.4; p = 0.005) and pain at rest (3.1 ± 1.7 vs. 1.9 ± 1.4; p = 0.011) were registered in the sling exercise group. A comparison of the baseline values for these parameters to those reported at follow-up, without specific stabilization or strengthening exercises, it was found that the effect lasted for a minimum period of 3 months (p
