[Purpose] To evaluate the incidence of pain originating from the sacrotuberous ligament after sacroiliac joint treatment, and to determine effective physical therapeutic options for sacrotuberous ligament pain. [Participants and Methods] Among 303 patients with sacroiliac joint dysfunction, 57 patients (20 males, 37 females) with persistent lower-buttock pain after sacroiliac joint injections were included in the study. The incidence of sacrotuberous ligament pain and the physical findings from the first evaluation were investigated by physical therapists. [Results] Diagnostic sacrotuberous ligament injections identified lower-buttock pain originating from the sacrotuberous ligament in 57.9% of the patients (33 out of 57 patients) after treatment of sacroiliac joint dysfunction. Of these, 11 patients experienced relief after sacrotuberous ligament injection alone; the others required physical therapy. Sacrotuberous ligament relaxation alone was effective in eight patients; biceps femoris relaxation was required in eight patients; and gluteus maximus contraction exercise was required in six patients. [Conclusion] After sacroiliac joint treatment, the incidence of residual sacrotuberous ligament pain in the persisting lower-buttock pain was 57.9%. In addition to sacrotuberous ligament relaxation, biceps femoris relaxation was effective in patients who showed both higher differences in the straight leg raising test and biceps femoris tenderness, while gluteus maximus contraction exercises were effective in patients with gluteus maximus weakness.
