A recent study investigated the effects of spinal manipulation of the lumbar and sacroiliac joints in twenty patients with lumbar disk herniation combined with lack of sacroiliac motion (hypomobility). The patients received five spinal manipulations over a two-week period, which led to significant improvements in back and leg pain that persisted up to one month following their final treatment. The results show that spinal manipulation can be beneficial in the management of pain and functional disability in patients with lumbar disk herniation and concomitant SIJ hypomobility.
