There has been extensive literature examining the efficacy of exercise interventions in the treatment of depression over the past few decades. However, there is ongoing debate regarding the optimal dosage, and the implications of utilising physiotherapists for the management of clinically depressed adults using exercise has not been examined.
OBJECTIVES:
This review aimed to examine the effectiveness of exercise as a treatment for depression (without comorbidities) and to determine the most effective dosage/mode to treat this population. This review strived to appraise the literature for a potential role for physiotherapists in depression management.
METHODS:
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, a search for randomized controlled trials was conducted on the nine databases. All studies were appraised for quality using the Physiotherapy Evidence Database (PEDro) scale and Cochrane Risk of Bias Tool (RoB). Data was manually extracted, and pre- and post-intervention depression scores and program variables were analysed.
RESULTS:
Of the 5036 papers retrieved, 7 papers met this review’s inclusion criteria. The results of the meta-analysis reveal that exercise as a sole treatment and as an add-on is significantly effective in reducing depressive symptoms. The findings support the use of moderate intensity aerobic exercise for three sessions per week.
CONCLUSIONS:
Exercise was shown to significantly improve depressive symptoms in depressed adults. This review adds to the growing body of evidence regarding the important role of physiotherapists in the treatment of psychiatric disorders in the design and implementation of exercise interventions.
