Low Level Laser Versus Neural Mobilization of Brachial Plexus on Shoulder Dysfunction Post Liver Donation

The first experimental will receive LLLT using the Fisioline Lumix 2 (Italy). Participants will be placed in a comfortable, supported sitting position and will wear protective eyeglasses to prevent retinal damage. The LLLT (GaAs type, 1-10 mW, 904 nm) will be applied to the most painful points on the deltoid and/or upper trapezius muscles. Treatment will target a minimum of two and a maximum of four painful points, with each point irradiated for 3-4 minutes, for a total session duration of up to 15 minutes.

The second experimental will receive Neural Mobilization Therapy (NMT). The procedure will begin by positioning the patient in a sitting position. The initial positioning will involve placing the patient's arm at their side with the elbow bent at 90 degrees. The therapist will gently extend the patient's shoulder (moving the arm backward) while keeping the elbow bent, creating tension on the axillary nerve. This tension will be held for a few seconds, ensuring it remains within the patient's tolerance and does not cause discomfort or pain. The shoulder will then be slowly returned to the initial position, releasing the tension on the nerve. This sequence of tension and release will be repeated, gradually increasing the range of motion as tolerated. The treatment will consist of three sets of 10 repetitions, with a one-minute rest between sets, performed three times per week for a total of 12 sessions over four weeks.

The following exercises will be performed by the patients of three groups. Pendulum exercise, Isometric Scapular Retraction, Rotator cuff exercise, Wall creeping exercise, Active assisted ROM exercises, Codman exercises. Each exercise will be performed for all movements namely flexion extension and abduction-adduction, one sets of each 10-15 repetitions within pain-free range and instructed to carry out their activities of daily living.
