Abstract
BackgroundThe promotion of physical activity is a major field in rehabilitation and health promotion but evidence is lacking on what method or strategy works best. Ensuing from this research gap, the present study compared the effectiveness of a comprehensive theory based multicomponent intervention (Movement Coaching) to a low intensity intervention in low back pain patients.MethodsA monocenter randomized controlled trial with three measuring points (T0 = baseline, T1 = six month follow-up, T2 = twelve month follow-up) was conducted. N = 412 chronic low back pain patients participated. The Movement Coaching group (n = 201) received a comprehensive multicomponent intervention with small-group intervention, phone- and web 2.0-intervention. The low intensity control (n = 211) received two oral presentations that were available for download afterwards. Main outcome was total physical activity measured by Global Physical Activity Questionnaire at 12 month follow-up. Additionally, workplace, leisure time and transportation activities were compared. A split-plot anova was conducted for evaluating repeated measure effects and between group effects.ResultsAt six and twelve month follow-up there were no statistically significant between group differences in total (T1: p = 0.79; T2: p = 0.30) as well as domain-specific physical activity (workplace (T1: p = 0.16; T2: p = 0.65), leisure time (T1: p = 0.54; T2: p = 0.89), transportation (T1: p = 0.29; T2: p = 0.77) between Movement Coaching and the control group. In both groups, workplace physical activity showed the highest proportion of total physical activity. From baseline to twelve month follow-up the results showed a decline in total physical activity (Movement Coaching: p = 0.04; control group: p = 0.50).ConclusionsThe comprehensive Movement Coaching intervention was not found to be more effective than a low intensity intervention in promoting total and domain-specific physical activity in chronic low back pain patients.Trial registrationThis study is registered at German Clinical Trials Register (DRKS)-ID: DRKS00004878.
Highlights
The promotion of physical activity is a major field in rehabilitation and health promotion but evidence is lacking on what method or strategy works best
Theory based and tailored interventions are more effective at promoting physical activity than standard interventions [9], the aim of the present study was to compare two different interventions: A theory-based multicomponent intervention (Movement Coaching) comprising three different components and a low-intensity and low cost intervention merely comprising two general presentations on physical activity without theoretical foundation
Study design The study was conducted as a single centre randomised controlled trial with three measuring points: T0 = start of inpatient rehabilitation, T1 = six month follow-up, T2 = twelve month follow-up
Summary
The promotion of physical activity is a major field in rehabilitation and health promotion but evidence is lacking on what method or strategy works best. Ensuing from this research gap, the present study compared the effectiveness of a comprehensive theory based multicomponent intervention (Movement Coaching) to a low intensity intervention in low back pain patients. The promotion of physical activity is a major field in rehabilitation and health promotion. The literature shows that comprehensive and highquality interventions achieve the most significant long-term increases in physical activity behaviour [9]. Though face-to-face interventions are considered the most effective approach [11], long-term interventions such as telephone-based interventions, internet-based interventions and mailed support are considered to increase sustainability [9, 11]. Whether individually tailored interventions are more effective than standard interventions [12, 13]
