Abstract
OBJECTIVE: The aim of this study was to examine the effects of platelet-rich plasma (PRP) on pain and functional outcomes in patients with hemiplegic shoulder pain. We compared the effects of PRP against saline solution by designing a double blind, randomized, prospective study. DESIGN:Forty-four patients with hemiplegia were included in this study. All patients received a total of 3 injections, 1 week apart. The first group received PRP injections while the second group received placebo injections. After 3 months of follow-up, 40 patients completed the trial. Primary outcome measure was movement-induced pain score (VAS), and secondary outcome measures were spontaneous pain score, shoulder passive range of motion (ROM), functional independence measure score, and the amount of paracetamol used. All subjects were evaluated at baseline, 1 week, 1 month, and 3 months after the completion of the last injection. RESULTS: Both groups showed an improvement in spontaneous and movement-related pain scores and shoulder passive ROM values on 1st and 3rd month visits (p < 0.05). No significance difference was detected between groups (p > 0.05). Similarly, FIM scores improved significantly in both groups (p < 0.05) but no difference was found between groups. Paracetamol use did not differ significantly between groups. CONCLUSION: The PRP injections were found not to be superior to placebo. Improvements in both groups can be attributed to the use of rehabilitation techniques and exercises in all patients. There is still need for further research to show whether PRP is a treatment option in the course of hemiplegic shoulder pain. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03931824.
