Sacroiliac Joint Mobilization Immediate Improved Clinical Features of Non-Specific Low Back Pain with Sacroiliac Joint Dysfunction

The sacroiliac joint (SIJ) is an important primary source of low back pain (LBP). Sacroiliac joint dysfunction (SIJD) can be found in both symptomatic and asymptomatic adults, resulting in pain and limitation of degrees of lumbar spinal, and SIJ movement. SIJ mobilization is another method of physical therapy treatment supported by studies in several aspects, namely reducing pain and promoting the movement of SIJ. However, no previous study has evaluated the immediate effect of the SIJ mobilization on the lumbar spinal flexibility improvement. The purpose of this study was to investigate the immediate effects of SIJ mobilization on lumbar spinal flexibility, pain perception, and pressure pain threshold (PPT) in patients with non-specific low back pain (NSLBP) associated with SIJD. Sixteen participants (8 males and 8 females with a mean age of 39.3 ± 12.7 years) were randomly assigned into two groups. Experimental group was treated with SIJ mobilization 30 oscillations / set, 3 sets / one side (total within 4 minutes). The control group was instructed the same starting position (rest in side lying for 2 minutes / side) as of the experimental group but just with the sham method. Both groups were immediately pre and post-treatmen
