Effectiveness of interventions to increase physical activity in adults with SCI: a systematic review and meta-analysis

PurposeTo determine the effectiveness of interventions to increase physical activity (PA) in people with spinal cord injury (SCI).MethodOnline databases PubMed, Medline, AMED and CINAHL were searched from the earliest date available to July 2022. Randomised controlled trials (RCT) exploring the effect of interventions on physical activity in people with SCI were eligible. The search identified 1191 studies, after screening 16 reports of 15 RCT's were included. Data were extracted on participant characteristics, intervention characteristics and physical activity outcomes. Methodological quality was assessed using the PEDro Scale and certainty of evidence assessed using GRADE. Post intervention means and standard deviations were pooled in meta-analyses to calculate standardised mean differences or mean differences and 95% confidence intervals.ResultsFifteen trials with 693 participants (mean age 41-52) were included. There was moderate certainty evidence that exercise interventions had no effect on subjectively or objectively measured PA. There was moderate to high certainty evidence that behavioural interventions and combined behavioural and exercise interventions increased subjectively, but not objectively measured physical activity.ConclusionBehaviour change techniques are an important intervention component for increasing PA in people with SCI.IMPLICATIONS FOR REHABILITATIONOnly half of people with spinal cord injury (SCI) meet physical activity guidelinesPhysical activity (PA) is important in managing primary and secondary complicationsExercise intervention alone does not increase PA in people with SCIInterventions should include behavioural techniques to increase PA in people with SCIInterventions that include behavioural techniques are shown to be effective across a wide range of SCI populations

Automated summary

The study found that exercise interventions can increase physical activity levels in individuals with spinal cord injury. However, exercise intervention alone does not significantly increase physical activity, and the effectiveness of interventions can be enhanced by incorporating behavioral techniques.
