BackgroundChronic shoulder pain following cerebrovascular stroke (CVS) is a major problem that persists after maximum recovery of motor functions. Such pain has been attributed to altered shoulder joint kinematics causing soft tissue damage.AimEvaluation of shoulder proprioception in the ipsilateral paretic arm and contralateral unaffected side 6 months following cerebrovascular event.Subject and methodThirty adult patients (G1) with ischemic strokes ranging from 6 months to 1 year and 30 healthy control (G2) were assessed for shoulder proprioception. Angular displacement error was measured during active and passive repositioning of shoulder external and internal rotation in both patients’ shoulders and in control’s dominant upper limb.ResultsStatistically significant increase in angular displacement error was found in all tests in the affected shoulder compared to the unaffected contralateral shoulder and dominant arm of control subjects. The contralateral unaffected shoulder of patients showed within normal values and no differences with control values. Passive external and internal rotations showed statistically higher errors in patients with cortical lesions compared to those with subcortical lesions.ConclusionSix months following the CVS, shoulder proprioception deficit in the affected hemiparetic side persists. Contralateral side shows no abnormalities. Cortical lesions might be associated with late shoulder proprioception recovery compared to subcortical lesions. The side of the lesion does not seem to affect the severity of proprioception deficit.
