Hemiplegic shoulder pain (HSP) is a common complication that occurs after stroke and has been reported in up to 84% of hemiplegic patients. One of the recommended treatment options for shoulder pain is high-intensity laser therapy (HILT). This study aimed to determine the effectiveness of high-intensity laser therapy on pain, function and hand grip strength in patients with hemiplegic shoulder dysfunction. Forty-four hemiplegic patients were randomly divided into two groups: Group 1 (study group, n = 22) received 3 HILT sessions a week for three weeks in combination with three sessions of therapeutic exercise per week for three weeks, and Group 2 (control group, n = 22) received a conventional exercise program for HSP three times a week for three weeks. Shoulder pain was evaluated using the McGill pain questionnaire (MPQ), the functional outcome of the shoulder was evaluated with the University of California-Los Angeles functional scale (UCLA), and handgrip strength was evaluated with a hydraulic hand dynamometer. The increase in the UCLA scores and the decrease in the MPQ scores after treatment were significant in the study group (p < 0.001) as well as in the control group (p < 0.05) in comparison with the pretreatment between-group comparison. Additionally, the increase in hand grip strength was significant in both groups after treatment (p < 0.001). The study group showed significant improvement over the control group with respect to the UCLA score, handgrip strength, and MPQ score (p < 0.001). HILT combined with therapeutic exercise provides greater improvement than therapeutic exercise alone in terms of hemiplegic shoulder pain, dysfunction, and handgrip strength.
