Abstract
ABSTRACT Background Hemiplegic shoulder pain (HSP) is a prevalent clinical manifestation following stroke, often causing considerable discomfort and disability. Various therapeutic approaches have been developed to address HSP. Objectives This study aimed to compare the effectiveness of HILT versus US therapy in alleviating HSP in stroke patients. Methods A double-blind randomized controlled trial enrolled stroke patients with HSP within one year post-onset. Participants were randomly assigned to HILT (with sham US) or US therapy (with sham HILT). Both groups received 10-minute sessions of their assigned therapy modality along with daily shoulder range of motion (ROM) exercises 5 times per week over two consecutive weeks. Pain reduction was the primary outcome, with shoulder ROM as secondary outcomes. Results Thirty patients (11 women, 19 men; mean age: 60.80 ± 11.51 years) were included. After the two-week intervention, significant improvements were observed in pain reduction at rest and during motion in the HILT group, and in pain reduction during motion and shoulder internal rotation in the US group compared to pre-treatment values within each group. However, there was no significant difference between the HILT and US therapy groups in any evaluated parameter. Conclusions Comparable efficacy was found between HILT and US therapy in reducing pain and improving shoulder ROM for HSP in stroke patients. Both modalities, when combined with shoulder ROM exercises, offer viable options for managing HSP in this population. Further research with larger sample sizes is needed to validate these findings and explore long-term outcomes.
