Fall-related injuries are a leading cause of morbidity and mortality in older adults worldwide.
While the use of exercise interventions to address this issue has been extensively studied, exercise variables have not sufficiently been reported. Moreover, the application of these variables in balance training has been based on expert opinion rather than research evidence.
Ninety-five eligible trials were extracted from previous systematic reviews, of which eighty were used for meta-regressions. Eligible studies reported at least one end-intervention balance outcome measurement that was consistent with the five subgroups of balance exercise identified.
Risk of bias was assessed using the Physiotherapy Evidence Database (PEDro) scale. The risk of systematic bias in the outcomes related to study quality was low.
