Modulation of stretch reflexes of the finger flexors by sensory feedback from the proximal upper limb poststroke.
Neural coupling of proximal and distal upper limb segments may have functional implications in the recovery of hemiparesis after stroke. The goal of the present study was to investigate whether the stretch reflex response magnitude of spastic finger flexor muscles poststroke is influenced by sensory input from the shoulder and the elbow and whether reflex coupling of muscles throughout the uppe...

Background and Aim: Spasticity is a velocity-dependent increase in tonic stretch reflexes (muscle tone) with exaggerated tendon jerks, resulting from hyperexcitability of the stretch reflex. The measurement of spasticity is necessary to determine the effect of treatments. The Modified Ashworth Scale is the most widely used method for assessing muscle spasticity in clinical practice and research...
متن کاملEffect of sensory feedback from the proximal upper limb on voluntary isometric finger flexion and extension in hemiparetic stroke subjects.
This study investigated the potential influence of proximal sensory feedback on voluntary distal motor activity in the paretic upper limb of hemiparetic stroke survivors and the potential effect of voluntary distal motor activity on proximal muscle activity. Ten stroke subjects and 10 neurologically intact control subjects performed maximum voluntary isometric flexion and extension, respectivel...

Background and Objective: Stroke results in increased sensory disorder, motor impairment and functional deficit. Sensory stimulation is the basis for beginning of the process of brain plasticity and recovery of sensory motor function in the affected limbs. The objective of this study was to investigate the effect of sensory retraining on functional recovery of upper limbs in patients with ische...
متن کاملFour weeks of daily stretch has little or no effect on wrist contracture after stroke: a randomised controlled trial.
QUESTIONS In adults undergoing rehabilitation after stroke, does 30 minutes of daily stretch of the wrist and finger flexors for four weeks prevent or reverse contracture, decrease pain, or improve upper-limb activity? Are any gains maintained one week and five weeks after the cessation of stretching? DESIGN Randomised controlled trial with concealed randomisation, assessor blinding, and inte...
