Abstract: Study explored potential relationships among the mechanisms responsible for hand impairment following stroke. Ninety-five stroke survivors with severe, chronic hand impairment were evaluated. Custom instrumentation created precise perturbations and measured kinematic responses. Muscle activation was recorded through electromyography. Strength, spasticity, muscle relaxation time, and muscle coactivation were quantified. Maximum grip strength in the paretic hand was only 12 percent of that achieved by the nonparetic hand, and only 6 of 95 participants were able to produce any net extension force. Despite force deficits, spastic reflex response of the finger flexor evoked by imposed stretch averaged 90.1 percent of maximum voluntary activation, relaxation time averaged 3.8 seconds, and coactivation during voluntary extension exceeded 30 percent of maximum contraction, thereby resulting in substantial net flexion. Surprisingly, these hypertonicity measures were not significantly correlated with each other. Survivors of severe, chronic hemiparetic stroke experience profound weakness of both flexion and extension that arises from increased involuntary antagonist activation and decreased voluntary activation. The lack of correlation amongst hypertonicity measures suggests that these phenomena may arise from multiple, potentially independent mechanisms that could require different treatments.
