Efficacy of Physical Activity Promoting Interventions in Physical Therapy and Exercise Therapy for Persons With Noncommunicable Diseases: An Overview of Systematic Reviews.

ABSTRACT

OBJECTIVE: The objective of this study was to synthesize the evidence from systematic reviews on the efficacy of physical therapy and exercise therapy, including interventional elements explicitly aiming at physical activity promotion (PAP) in patients with noncommunicable diseases (NCDs). METHODS: PubMed, Scopus, PsycINFO, and Cochrane Database of Systematic Reviews were searched from inception to February 28, 2023. Two independent reviewers screened the literature to identify systematic reviews that evaluated the effects of physical therapy and exercise therapy, including PAP interventions. Patient-reported and device-based measures of physical activity (PA) outcomes were included. Qualitative and quantitative data from systematic reviews were extracted by 2 independent reviewers. Assessment of the methodological quality of the included systematic reviews was performed using A Measurement Tool to Assess Systematic Reviews (AMSTAR 2). We assessed primary study overlap by calculating the corrected covered area and conducted the evidence synthesis in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: Fourteen systematic reviews were included in the present overview, including patients with a variety of NCDs. Most included systematic reviews had critically low (n = 5) to low (n = 7) methodological quality. Most meta-analyses (67%; 8/12) provided evidence supporting the short- and long-term efficacy of PAP interventions, but not all pooled estimates were clinically relevant. Only three of the systematic reviews with meta-analysis included an assessment of the certainty of the evidence. The evidence from systematic reviews without meta-analysis was inconclusive. CONCLUSIONS: The results of the present overview suggest that PAP interventions in physical therapy or exercise therapy may be effective in improving PA for patients with NCDs in the short and long term. The results should be interpreted with caution due to the limited certainty of evidence and critically low-to-low methodological quality of the included systematic reviews. Both high-quality primary studies and systematic reviews are required to confirm these results. IMPACT There is limited evidence that PAP interventions in physical therapy and exercise therapy may be effective in improving PA for patients with NCDs.
