OBJECTIVE: Fear of falling (FOF) contributes to activity restriction and institutionalization among older adults, and exercise interventions are linked to reduction in FOF. Adhering to exercise principles and adapting optimal exercise parameters are fundamental to optimizing the effectiveness of exercise interventions. The purpose of this review was to describe FOF exercise interventions in community-dwelling older adults, evaluate the extent to which these interventions followed the exercise principles and reported exercise parameters, and quantify the effect of these interventions on reducing FOF. METHODS: Randomized controlled trials (RCTs) of FOF exercise interventions in older adults (>= 65 years) were identified from 4 databases. The methodological quality of RCTs was assessed using the PEDro scale. A random-effect model was used in the meta-analysis. RESULTS: Seventy-five RCTs were included in this review. With regard to reporting exercise principles, specificity was reported in 92% of trials, progression in 72%, reversibility in 32%, overload in 31%, diminished return in 21%, and initial value in 8%. For exercise parameters, 97% of RCTs reported exercise type; 89%, frequency; and 85%, time. Only 25% reported the intensity. The pooled effect of exercise interventions on FOF among all included studies was a standard mean difference of -0.34 (95% CI 0.44 to 0.23). CONCLUSIONS: This study showed a significant small-to-moderate effect size of exercise interventions in reducing FOF among community-dwelling older adults. Most exercise principles and intensity of exercises were not adequately reported in included trials.
