hi! my self mukul.PT. well i have seen this type of patients daily it is simply the inflamation of ligament over the SIJ. in this patient usually complain the pain in lower back sometimes it rediate to the lower limb and pt. fell crump in the lower back (i m telling u that what i seen and what my pt. complain to me) the pt. with this type of prob. has to avoid taking weight.wearing high heeled sandels,and has to sleep on hard bed try to sleep in pron. position.
THE BEST TREATMENT FOR THIS IS S.W.D.:- 15 SITTINGS(VARY WITH PATIENT AND CONDITION) so go for it ...........
