Vibration has become of increasing interest to health professionals, primarily owing to reports that vibration can increase tissue blood flow. The aim of this review was to investigate the available scientific evidence on the effects of exogenous vibration on skeletal muscle perfusion. The databases searched from inception to December 2010 included Ovid MEDLINE, EMBASE, CINAHL via EbscoHost and CENTRAL. Experimental and observational studies, where exogenous vibration was an intervention, were included in this review. The main outcomes of interest were muscle blood volume, blood flow, blood flow velocity, arterial diameter and muscle temperature. One reviewer selected studies for inclusion, extracted data and assessed the quality of the eligible studies. Percentage change in muscle perfusion outcome was the measure of treatment effect, and regression analysis was used to investigate associations …
