【Purpose】We investigated the relationship between the maximum hip flexion, the pelvis, and the lumbar vertebrae on the sagittal plane.
【Methods】The study enrolled 30 healthy volunteers:13 females(18.5±2.1 age, Group-1:G-1), 17 females(45.0±3.1 age:G-2). The Hip Flexion Angle(HFA)were measured in two pelvic positions. (1)the Regular Position:RP(specified JOA and Rehabilitation Medical Association), and(2)the Limited Position(LP)of the posterior pelvic tilt by placing a 500ml PET bottle filled with water under the subject’s low back. The HFA of RP and LP in individual joints was assessed by Paired t-test(p<0.05). The HFA of RP and LP in two groups was compared in the coefficient of correlation. The HFA of RP, LP and(RP-LP)in two groups was assessed by Student’s t-test in two groups(p<0.05). All data were handled using R(3.1.1)software. We measured a 44 year-old female about the Lumbo Sacral Angle(LSA), the Lumbo Lordotic Angle(LLA)and the Sacral Slope Angle(SSA)by X-ray in 4 positions.
【Results】The HFA in G-1 and 2 decreased in LP by 17.9 degrees and 19.5 degrees on average, compared with RP(p<0.01). The coefficient of correlation of G-1 and 2 was 0.91 and 0.52, respectively. There was no significant difference of HFA of RP, LP and(RP-LP)in two groups. In the difference between the X-rays of the RP and LP, the SSA was 20.6°and the LLA was 13.6°. The LSA was nearly equal.
【Discussion】The HFA and the movement of the pelvic-lumbar vertebrae in the maximum hip flexion between the young females and in their 40’s show no significant differences.
