Eccentric Contraction Exercise For Shoulder Pain Syndrome

Short-term Effect of Eccentric Contraction Exercises in the Treatment of Patients With Shoulder Pain Syndrome: A Randomized Controlled Trial

The current study will help to determine the efficacy of a rehabilitation protocol that involves the use of eccentric contraction for patients with shoulder pain syndrome. This approach aims to improve recovery in terms of pain and function based on scientific evidence.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Eccentric Exercise Group; Patients in this group will receive a supervised rehabilitation protocol focusing on eccentric contractions of the shoulder muscles.	Other: Eccentric Training Protocol; A 6-week rehabilitation program, conducted for two sessions per week. Patients will receive specialized eccentric contraction exercises for the shoulder muscles, administered in addition to a standard physical therapy protocol.; Other: Traditional Physical Therapy Only; A 6-week standard rehabilitation program, conducted for two sessions per week. Patients will receive Traditional physical therapy interventions only, which include ultrasound, range of motion (ROM) exercises, postural training and general strengthening routinely prescribed."
Active Comparator: Traditional Physical Therapy Group; Patients in this group will receive traditional physical therapy interventions commonly used for shoulder pain syndrome	Other: Traditional Physical Therapy Only; A 6-week standard rehabilitation program, conducted for two sessions per week. Patients will receive Traditional physical therapy interventions only, which include ultrasound, range of motion (ROM) exercises, postural training and general strengthening routinely prescribed."

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Change from Baseline in Pain Intensity using the Visual Analog Scale (VAS)	Baseline and at the end of the 6-week intervention period.
Change from Baseline in Shoulder Pain and Disability using the Shoulder Pain and Disability Index (SPADI)	Baseline and at the end of the 6-week intervention period.

Secondary Outcome Measures

Outcome Measure	Time Frame
Change from Baseline in Functional Independence using the Functional Independence Measure (FIM)	Baseline and at the end of the 6-week intervention period.
