Measurement of LL, SS, Fs, and SS-Fs for patient in standing and sitting position. Patients in the control group (upper A and B) had 54.4° (change in LL from 60.1° to 5.7°) lumbar spine flexion and 53.9° (change in SS-Fs from 36.2° to − 17.7°) hip flexion from standing (A) to sitting (B). The pelvis rotated 36.5° (change in SS from 46.0° to 9.5°). Patients in the LDD group (Lower, C and D) demonstrated 8.7° (38.6° to 29.9°) lumbar spine flexion and 71° (58.9° to − 12.1°) hip flexion, from standing (C) to sitting (D). The pelvis rotated 5.8° (21.7° to 15.9°)
