In a prospective, randomised study, 30 patients with osteoporosis were led through systematic training over 4 months. Group A (n=10) did the ‘back school’ training programme, Group B (n=10) did normal device training and Group C (n=10) only took part in whole body EMS training. Concomitant medication was not altered during the training. At the end of the experiment, there were improvements in bone density measurement and physical capacity (initial examination – original investigation), but only group C (EMS training) exceeded the threshold of significance.
