Motor deficits are common following stroke. Approximately 43% to 69% of people suffering from a stroke have upper-extremity impairment,1,2 and 4 years after a stroke, 67% still experience non-use of the affected arm as a major problem.1 One of the features of motor deficits after a stroke is spasticity. Spasticity develops slowly, peaking 1 to 4 months after onset of stroke.3 Watkins et al.4 found that 1 year after stroke, 38% of patients demonstrated spasticity.
