Effectiveness of a high-intensity laser for improving hemiplegic shoulder dysfunction: a randomized controlled trial.

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.
