[Sustainable increase of physical activity by rehabilitation].

Patients with musculoskeletal diseases are much less physically active than healthy individuals. They could benefit from an increase in physical activity and a sustainable change in lifestyle in many ways, to which inpatient rehabilitation can make a substantial contribution. In this prospective observational study (pre-post design), physical activity (using the Freiburg physical activity questionnaire) and depressiveness (using the Beck depression inventory, BDI) were assessed in 202 rehabilitation patients (124 female, 77 male) with musculoskeletal disorders (ICD diagnoses M) at different catamnestic points in time (at the beginning of rehabilitation, after 3, 6, 9, and 12 months). The increase in activity was analyzed as a function of the activity level at the beginning as well as depressiveness. At 3 months after rehabilitation activity levels were 47.8% higher than at the beginning, corresponding to an increase in median activity from 5 to 7.2 h per week. Of the participants 78.6% showed a positive difference to the starting level after 3 months. The mean BDI score decreased during the rehabilitation intervention; a correlation between decreasing BDI and increasing physical activity could not be shown. A single intervention (3-week rehabilitation) succeeded in increasing physical activity over 12 months, whereby the increase in physical activity did not correlate with the initial activity level, concluding that even previously inactive patients benefit from rehabilitation.
