Abstract
[Purpose] We investigated the effects of individual strengthening exercises for subdivisions of the gluteus medius in a patient with sacroiliac joint pain. [Subject] A 32 year-old female who complained of pain in the posterior area of the left iliac crest and sacroiliac joints over a period of 6 months was the subject of this study. [Methods] She performed individual strengthening exercises for subdivisions of the gluteus medius over 3 weeks. Pain-provocation tests and VAS scores were evaluated before and after the intervention. [Results] After individual strengthening exercises for subdivisions of the gluteus medius, the subject showed no pain in the Gaenslen, Patrick, or REAB tests for the left sacroiliac joint. The VAS score was less the 3/10, compared with 7/10 initially. [Conclusion] Individual strengthening exercises for the subdivisions of the gluteus medius were effective at reducing SI joint pain for this patient.
