Glenohumeral Subluxation

This study will examine infants with a birth-related nerve injury called neonatal brachial plexus palsy, which can affect movement in the arm and sometimes cause the shoulder joint to shift out of its normal position (subluxation). Researchers will use ultrasound imaging to measure the shoulder joint and will compare these measurements with findings from a physical examination, to determine which clinical signs can help predict whether a baby's shoulder will develop this problem. The goal is to help doctors detect shoulder problems earlier, so that treatment can start sooner.

The aim of this single-blind randomized controlled trial is to compare the effects of two therapies-neuromuscular electrical stimulation (NMES) and electromyographic (EMG) biofeedback-in stroke patients with shoulder (glenohumeral) subluxation. The study will evaluate changes in shoulder structure and function by measuring the acromion-greater tuberosity distance, supraspinatus and posterior deltoid muscle thickness, shoulder range of motion, and Brunnstrom stage of the upper extremity and hand. Clinical outcomes such as shoulder pain, stroke-specific quality of life, and the Shoulder Pain and Disability Index (SPADI) will also be assessed. This trial is designed to provide evidence on which therapy may be more effective for improving shoulder stability, reducing pain, and enhancing quality of life in stroke survivors with shoulder subluxation.
