PURPOSE: The current study determined the immediate and one year follow-up effects of a multifunctional osteoporosis orthosis, manufactured without rigid elements. MATERIALS AND METHODS: The study evaluated 54 osteoporosis patients before and after a 12 months time interval. Patients were randomly assigned to two study groups. The participants of the test group were asked to wear the orthosis throughout the one year test period. Patients of the control group carried no specific device. First and second measurements evaluated the thoracic kyphosis as well as the spinal curvature during upright standing. The study also investigated the experienced pain level and the number of falls. During the second examination the spinal posture of twelve randomized selected subjects were evaluated before and after a three hours orthosis wearing period. RESULTS: The immediate effects, obtained during the first examination, demonstrated a substantial amount of spine straightening facilitated by orthosis wearing. During the orthosis condition the subjects accomplished at least 60% of their maximum active thoracic erection. Almost 80% to 90% of all participants experienced an increase in spinal erection and trunk stability. Subjects were able to maintain the straightened position over extended time periods. CONCLUSIONS: The results point to a direct use of the examined orthosis. Facilitating sensomotor effects are achieved without rigid elements. The effects induced by air pads improve the relief of pain by gate control mechanisms. Erect posture, pain inhibition, enhanced activity along with improved coordination and more effective physiotherapy should reduce the frequency of falls and the fracture incidence.
