ABSTRACT
Due to the positive effects of rehabilitation declining over time, the aim of this study was to investigate the long-term physical activity level (PAL) following inpatient rehabilitation in relation to the use of a smartphone-based after-care program. 202 patients (mean Body Mass Index (BMI): 30,8 kg/m2; 61% female) with chronic diseases (e.g., diabetes mellitus, obesity, chronic low back pain, depression) were recruited between 08/2020 and 08/2021 in this single-arm observational study. All patients underwent a 3-week inpatient rehabilitation program. PAL (in total activity minutes/week) was measured with a validated (online) questionnaire (Freiburger Questionnaire on PA) after 3, 6, 9, and 12 months. App usage (online time, completion of a course) was recorded automatically and used to evaluate the app user behavior (adherence). A variety of socio-economic factors (age, sex, education level, income etc.) were collected to identify possible barriers of app use. Except for sex, no significant difference was observed for socio-economic factors regarding app usage behavior. Median PAL significantly increased after rehabilitation in the total cohort from 360 min/week (before rehabilitation) to 460 min/week 6 months after rehabilitation, then declined to 420 min/week 9 months after rehabilitation before falling below baseline level after 12 months. There was no significant difference in PAL between app users (45%, 91/202) and non-users (55%, 111/202), although app users tended to retain higher activity levels after 3 and 6 months, respectively. Overall, our study emphasizes the effectiveness of a 3-week rehabilitation program on PAL and the acceptance and usability of a smartphone-based after-care program in this patient group. The adherence to this 3-months after-care app program was acceptable (30%), with modest evidence supporting the effectiveness of app use to sustain PAL in the short term.
ABSTRACT
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 7.2â¯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.
