Suprascapular Nerve Block and Proprioception in Hemiplegic Shoulder Pain: A Randomized Controlled Study

Recruiting now · Not applicable

Conditions studied: Hemiplegic Shoulder Pain, Proprioception, Suprascapular Nerve Block

In brief

The purpose of this prospective randomized controlled clinical trial is to evaluate the effect of suprascapular nerve block on shoulder joint proprioception in stroke patients with hemiplegic shoulder pain. Fourteen patients aged 18-80 years with hemiplegic shoulder pain will be randomized into two groups. One group will receive suprascapular nerve block followed by a standardized physical therapy program, while the control group will receive the same physical therapy program alone. The primary outcome is shoulder joint proprioception. Secondary outcomes include pain intensity, shoulder range of motion, motor recovery, stroke-specific quality of life, and upper extremity functional outcomes. The results of this study are expected to clarify the role of suprascapular nerve block on proprioception and rehabilitation outcomes in patients with hemiplegic shoulder pain.
