Impairment of arm function is more common than lower limb impairment in stroke patients and is also more resistant to treatment. Several clinical trials with stroke patients have produced statistically significant gains in upper limb function when using instrumental playing and treatments where rhythm supports the priming and timing of movements. Based on the positive results from controlled and non-controlled trials, the Cochrane review of music therapy for acquired brain injury (Bradt, et al., 2010) recommends further investigation into rhythm based techniques to treat hemiparesis in stroke patients, and that future studies need to examine the relationship between the frequency and duration of interventions and treatment effects.
