Effect of whole-body vibration exercise in the pelvic floor muscles of healthy and unhealthy individuals: a narrative review

Abstract

The aim of this narrative review was to determine effects of whole body vibration exercises (WBVE) on the pelvic floor muscle (PFM) of healthy and unhealthy individuals. Searches were performed in the databases PubMed, Scopus, Science Direct and PEDRo. The level of evidence and methodological quality of the selected papers were determined. It was included six studies with a total of 189 participants (95.76% women) with ages ranging from 18 to 68 years. It was reported that WBVE: (I) improves the PFMs strength and quality of life (QOL) in individuals with urinary incontinence; (II) does not cause (PFM) fatigue in nulliparous continent women; (III) leads to higher (PFM) activation in subjects with weakened (PFM) and achieves higher pelvic floor (PF) activation than maximum voluntary contraction alone; (IV) in an individual with postprostatectomy stress urinary incontinence (SUI), over a period of 6 weeks after starting treatment, the patient regained continence (usage of 1 safety pad) and (V) has a significant effect on the electromyographic response and additionality and the rating of perceived exertion (RPE) significantly increased with increased frequency of the mechanical vibration. Relevant findings are presented and demonstrated that the WBVE might be highly relevant to the management of clinical disorders of the (PFM). Nevertheless, this intervention must be more understood and known to be used in the management of individuals with impairment of the (PFM) and there is the necessity of more research in this area.
