Objective : This systematic review aimed to investigate the effect of focal muscle vibration in
patients with post-stroke spastic hemiplegia.
Methods : We searched literature published between April 2009 and October 2017 using
PubMed and RISS databases. The main search terms were Vibration therapy, Focal vibration,
Somatosensory, Upper limb, and Spasticity after stroke. Based on inclusion/exclusion
criteria, 6 articles were selected.
Results : Articles on focal muscle vibration intervention ranged from evaluation of application-
only vibration to muscle vibration with task-oriented activity. Intervention effects on
upper extremity spasticity and function and activities of daily living were assessed. There
were significant effects on upper extremity spasticity, function, and cortical excitability.
Conclusions : This study can provide information on focal muscle vibration for use by clinical
therapists. However, further studies are needed to identify the optimal stimulation site
and frequency/amplitude of application to maximize the effects of focal muscle vibration.
