Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Stroke is a leading cause of balance impairment and trunk muscle weakness, which restricts independence in daily activities. Neuromuscular electrical stimulation (NMES) is a safe rehabilitation method to activate muscles. This study will evaluate the effects of NMES applied to the abdominal muscles on balance and ultrasound-measured muscle thickness in stroke patients. The findings may provide evidence for new treatment strategies to enhance trunk function and improve quality of life after stroke.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Stroke is a leading cause of long-term disability and frequently results in impaired balance and trunk muscle weakness, limiting independence in daily life. Abdominal muscles are essential for postural stability, and their weakness may adversely affect mobility and functional outcomes in stroke patients. Neuromuscular electrical stimulation (NMES) is a safe rehabilitation method used to promote muscle contraction and improve strength. While NMES has shown positive effects on limb muscles, its impact on abdominal muscles and balance remains insufficiently studied.

In this prospective randomized controlled trial, participants will be randomly allocated into two groups. The control group will perform core stabilization exercises, while the intervention group will receive core stabilization exercises combined with abdominal NMES. Balance will be assessed using validated clinical scales, and abdominal muscle thickness will be measured by ultrasound. The study aims to determine the additional effects of abdominal NMES on balance, trunk control, and functional recovery in stroke patients.

Intervention Model

PARALLEL

This study is a prospective, randomized, parallel-group trial. Stroke patients will be randomly assigned to one of two groups: (1) an intervention group receiving neuromuscular electrical stimulation (NMES) applied to the abdominal muscles in addition to core stabilization exercises, or (2) a control group performing only core stabilization exercises.
