Non-pharmacological and non-surgical interventions for tremor: a systematic review

Tremor is a frequent disabling consequence of many neurological conditions. We performed a search of MEDLINE, CINAHL, EMBASE and the Cochrane Library to identify all primary research studies published up to November 2010 which investigated non-pharmacological and non-surgical treatments for tremor in humans. Neuromuscular physiotherapy, strength training and functional electrical stimulation show promise in their applicability and adaptability. Limb cooling may not be feasible for continuous management, but may be appropriate for specific tasks. Tremor-suppressing orthoses based on viscous materials, weighted splints and vibration therapies need further evaluation especially in the domiciliary setting and applied to improving personal activities of daily living. The evidence base for many rehabilitation interventions in tremor is poor. Future research should focus on high quality randomized controlled trials of non-pharmacological and non-surgical interventions which show promise.
