A double-blinded and placebo-controlled clinical trial with 19 participants was conducted. The participants were >30 years of age, had suffered a stroke between 1 and 6 months prior to the study, and had been diagnosed with having hemiplegic shoulder pain for over 1 month.
All participants received treatment once a day for 5 consecutive days and over the course of 4 weeks. The treatment group received electrical therapy, taping and exercise therapy. The purpose of taping was to support neuromuscular function and (according to the authors) to help mechanically support the shoulder.
Exercises consisted of passive and active assisted exercises. Active range of motion exercises were kept to less than 90 degrees of flexion and abduction to avoid impingement of the shoulder. Shoulder exercises were given for 20 minutes, and an additional 40 minutes of exercise for the trunk and lower limbs was provided.
