Purpose: The purpose of this study was to investigate the analgesic effect of infrared rays on the patients with musculoskeletal pain during the treatment session.
Materials and Methods: The subjects were 8 patients with shoulder pain. Before applying the infrared rays, we assessed subject’s pain with visual analogue scale, Korean version of critical care pain observation tool (CPOT-K) and measure the passive range of motion of the shoulder. 10 minutes and 20 minutes after applying infrared rays, we assessed the subjects with the tools mentioned above. As a sham treatment we applied sham laser on the same subjects and assess them with the same method.
Results: After applying infrared rays, visual analogue scale decreased significantly, and passive range of motion of shoulder seemed to improve but scores of CPOT-K did not change significantly. Visual analogue scale decreased in 10 minutes and decreased again in another 10 minutes.
Conclusion: This study demonstrated that the infrared therapy can relieve pain on subjects with musculoskeletal diseases and seem to increase the passive range of motion of the target joints. Findings also showed that the analgesic effect of the treatment starts in 10 minutes, so infrared therapy can be used as a quick modality for ameliorating musculoskeletal pains.
