Shockwave and Cryoflow for Shoulder Pain After Stroke

This study aims to find out whether combining two physical therapy treatments - Extracorporeal Shockwave Therapy and Cryoflow Therapy - can help reduce shoulder pain and improve function in patients who have developed rotator cuff tendonitis after a stroke. Participants will be divided into groups to receive either one therapy alone or both therapies together. Researchers will measure pain levels, shoulder movement, and daily function before and after treatment to see which approach works best. The goal is to find a more effective, non-drug way to manage shoulder pain in stroke survivors and help them regain better use of their arm.

This study will test whether combining Extracorporeal Shockwave Therapy (ESWT) and Cryoflow Therapy with traditional physical therapy is more effective than traditional therapy alone for reducing shoulder pain and improving arm function in stroke patients with rotator cuff tendonitis. Thirty stroke patients (ages 50-70) with moderate-to-severe shoulder spasticity (MAS grade 3) will be randomly assigned to one of two groups: Group 1 (Control): Receives traditional physical therapy (stretching, strengthening, PNF, hand function training) + placebo ESWT/Cryoflow. Group 2 (Experimental): Receives the same traditional therapy + real ESWT (7Hz, 15 min) and Cryoflow (14°C, 15 min). All patients will be treated 3 times per week for 8 weeks. Before and after treatment, researchers will measure: shoulder muscle tone (Modified Ashworth Scale), range of motion (digital goniometer), muscle strength (tensiometer), hand dexterity (Purdue Pegboard), and muscle activity (electromyography). The goal is to find a better, non-drug way to relieve shoulder pain and restore function after stroke.
