Effect of vibration foam rolling on the range of motion in healthy adults : a systematic review and meta-analysis

Professionals use foam rollers to improve range of motion (ROM). Re-cently, a vibrating foam roller (VFR) that combines the vibration function with a foam roller (FR) has been used. The purpose of this systematic review and meta-analysis was to determine the effects of a VFR on the improvement of ROM in healthy individuals. A systematic literature search was carried out in five international databases: PubMed, Em-base, PEDro, Cochrane Library, and Google Scholar. Eight clinical stud-ies, composed of six randomized controlled trials and two randomized crossover trials that involved 230 healthy participants were selected for analysis. Methodological quality was identified using the PEDro scale. The mean scores, 4.75±0.71, of the eight included studies, were classi-fied as fair. The results demonstrated that the VFR achieved better gains than the FR in improving ROM (standardized mean difference [SMD], 0.53; 95% confidence intervals [CIs], 0.29–0.77; I 2=55%). The VFR was more effective in improving the ROM than the FR in the hip and knee joints (hip: SMD, 0.56; 95% CI, 0.28–0.85; I 2=0%; knee: SMD, 0.86; 95% CI, 0.42–1.30; I 2=79%). The VFR may be an additional option to improve the ROM in healthy adults and athletes.
