This study was to compare the effects of joint mobilization, treadmill with insole, and joint mobilization and treadmill with insole on pain, pelvic angle, and foot pressure in patients with sacroiliac joint pain. 24 patients randomly assigned to joint mobilization group(n=8), treadmill with insole group(n=8), or joint mobilization and treadmill with insole group(n=8). Each groups were conducted 30 minutes a day, two days a week for four weeks. Pain was evaluated using visual analogue scale and pelvic angle was measured using palpation meter and foot pressure(fore/rear ratio) was measured using Gateview AFA-50 before intervention and after 4 weeks. All groups were significant differences pain in intragroup(p<.01). In pelvic angle, the joint mobilization group was statistically significant in the anterior tilt only, the joint mobilization and treadmill with insole group showed statistically significant improvement in both anterior and posterior tilt(p<.01), and the treadmill with insole group did not show any statistically significant change(p>.05). Also the joint mobilization and treadmill with insole group were significant differences in foot pressure(p<.01). All the interventions reduce sacroiliac joint pain and joint mobilization and treadmill with insole training are most effective changes in pelvic angle and foot pressure. This study can be used as a basic data for prevention of injury, posture correction and gait training in patients with sacroiliac joint pain, as well as chronic low back pain and plantar pressure problem.

Dysfunctional sacroiliac joint (SIJ) was considered as a source of the lower back pain. Several researchers investigated anatomy and biomechanics of the SIJ to understand the relationship between the lower back pain and the SIJ. Many studies concluded the SIJ has little movement. However, some of the studies using spinopelvic parameters mentioned high pelvic incidence (PI) change. Moreover, with the development of imaging techniques such as EOS system and vertical CT / MR, interest in sacroiliac joint movement and sagittal balance is increasing. Therefore, in this study, the movement characteristics of the sacroiliac joint were investigated by constructing an environment that could be measured and controlled more precisely than in past experiments. We used six fresh cadavers (male 1, female 5). The mean age was 85.25 (81~92) years and the mean height was 152.47 (142~161) cm. The pelvis was harvested by dissection. The hip bone, sacrum, coccyx, and ligaments between hip bone and sacrum were preserved. Patient-specific spacer blocks for fixation of the sacrum were designed by CT images and printed by a 3D printer. 3D printed patient-specific spacer blocks were fixated at the anterior and posterior surface of the sacrum, and the sacrum with the spacer blocks was fully fixated. The external load was applied in superior (+) and inferior (-) directions at pubic symphysis. Hip bone tilt angle, the movement of the pubic symphysis, and posterior superior iliac spine were measured with applied load. For these measurements, 13 optical markers and 4 motion capture cameras were used. We observed the remarkable SIJ movements in the female pelvis in 5 of 6 samples. However, only small movements were observed (-1.25 degrees and 1.90 degrees at +/- 200N, respectively). In the sample where the movement was observed, the hip bone tilt angle was 3.93 ± 0.49° under +100N and 4.86 ± 0.39° when applied with +200N. The tilt angle was 3.27 ± 1.42° when -100N was applied and 5.76 ± 1.63º applied with -200N (Fig. 2). The movement of the pubic symphysis was small (within 0.35 mm) in all cases, and the movement of the PSIS was 0.69 ± 0.52 mm, 0.70 ± 0.72 mm, 0.54 ± 0.02 mm, 0.79 ± 0.02 mm at +100N, +200N, -100N, and -200N respectively. Regardless of the loading direction, it showed an outward-opening behavior. The SIJ is a joint in which +/- 5 degrees of movement can occur due to weight bearing or muscle action, and this behavior should be considered in biomechanics studies. In particular, it mainly occurred in the pelvis of women, and studies on more samples are needed.

Purpose: The aim of this study is to confirm effects of different type of exercise on range of motion (ROM), visual analogue scale (VAS) and myofunction in patients with sacroiliac joint dysfunction (SID). Method: Twenty patients with SID participated in this study. They were allocated to two different exercise groups according to the order of enrollment; muscle energy technique group (MEG, n=10) and pelvic stabilization exercise group (PSG, n=10). The exercise program was conducted with 3 times per week, 1 hour for 12 week. ROM of external rotation (ER) and internal rotation (IR), VAS, and myofunction in hip joint was evaluated before and after exercise intervention. Result: In ROM of ER, there was a significant increase in MEG and PSG but PSG showed more increase. A significant increase in IR showed in MEG and PSG. VAS was a significant increase in MEG and PSG but PSG showed more increase. In change of myofunction, all variable showed a significant difference. Independent t test results for ROM, VAS, and myofunction showed more significant changes in PSG than MEG. Conclusion: This study demostrated that MEG and PSG showed a positive result to improve ROM, VAS, and myofunction and pelvic stabilization exercise is more beneficial exercise intervention than muscle energy technique in patients with SID. Further study with large sample is needed to confirm the result of this study.
