Secondary prevention after distal radius fracture: a prospective observational study of the effect of an exercise intervention
(English)Manuscript (Other academic)
This prospective observational study evaluated the effect of a four-week educational and exercise program, entitled the osteoporosis school. Two hundred and thirteen women with a distal radius fracture (mean age 66 years) were invited and 41 of them (mean age 64 years) accepted to join an exercise group (exercisers), 172 (mean age 66 years) declined and became a control group (non-exercisers). The intervention was followed by a one-year self-administrated exercise program. Bone mineral density (BMD), functional tests of dynamic and static balance, and leg strength were evaluated before and after the one-year intervention period and falls were registered in a fall diary. No statistically significant mean difference was found in dynamic or static balance between the exercisers and the non-exercisers. However, both groups showed improved balance (walking backwards and standing on one leg with eyes open over the study time (p<0.01). After the intervention, no significant difference was found between the groups in the one-leg rise test (p=0.494). The mean T-score was -1.859 at the baseline and -1.951 after intervention for the exercisers, and -2.0 and -2.064 for the non-exercises. There was no statistically significant difference in prospective falls between the exercisers and the non-exercisers (p= 0.272). Twelve of 41 exercisers (29.3%) and 37 of 172 non-exercisers (21.5%) reported one or more falls. Conclusion: Only 19% of the patients with a recent radius fracture accepted to participate in the osteoporosis school. The osteoporosis school with a 12-month home-based exercise program had no established effect on BMD, balance, leg strength or falls. This lack of proven efficacy for the secondary prevention of distal radius fractures, highlights the need for further research on better and more controlled interventions and for long-term randomised controlled follow-up studies.
