Lumbopelvic motion during seated hip flexion in subjects with low-back pain accompanying limited hip flexion

Abstract

Purpose Limited hip flexion may lead to a poor lumbopelvic motion during seated active hip flexion in people with low-back pain (LBP). The purpose of this study was to compare lumbopelvic motion during seated hip flexion between subjects with and without LBP accompanying limited hip flexion. Methods Fifteen patients with LBP accompanying limited hip flexion and 16 healthy subjects were recruited. The subjects performed seated hip flexion with the dominant leg three times. A three-dimensional motion-analysis system was used to measure lumbopelvic motion during seated hip flexion. Results During seated active hip flexion, the angle of hip flexion was significantly lower in patients with LBP accompanying limited hip flexion (17.4 ± 4.4 in the LBP group, 20.8 ± 2.6 in the healthy group; t = 2.63, p = 0.014). The angle of the lumbar flexion (4.8 ± 2.2 in the LBP group, 2.6 ± 2.0 in the healthy group; t = -2.96, p = 0.006) and posterior pelvic tilting (5.0 ± 2.6 in the LBP group, 2.9 ± 2.0 in the healthy group; t = 2.48 p = 0.019), however, were significantly greater in patients with this condition. Conclusions The results of this study suggest that limited hip flexion in LBP can contribute to excessive lumbar flexion and posterior pelvic tilting during hip flexion in the sitting position. Further studies are required to confirm whether improving the hip flexion range of motion can reduce excessive lumbar flexion in patients with LBP accompanying limited hip flexion.

The effect of abdominal drawing-in exercise and myofascial release on pain, flexibility, and balance of elderly females

“…MFR was effective for the treatment of neck pain patients21 ) . According to another study, when MFR was applied to neck pain patients, their extension angle significantly increased and when it was applied to patients with a shortened iliopsoas muscle, their waist flexion angle increased9, 22 ) . In the present study as well, when MFR was applied to elderly females with low back pain, their pain significantly decreased and their flexibility significantly improved.…”

“…When MFR was applied to the iliopsoas muscle of chronic low back pain patients, their low back pain decreased and their lumbar flexion increased. MFR is one of the therapeutic exercises that may heighten flexibility of the muscles and mobility of the joints9 ) .…”

Effects of Taping the Lower Back on the Lumbopelvic Region and Hip Joint Kinematics During Sit-to-Stand

“…Excessive lumbar flexion could be a risk factor for lower back pain (Kang et al, 2013;Kim et al, 2014;Sahrmann 2002). This study therefore aimed to assess the effect of taping the lower back on the kinematics of the lumbopelvic region and hip joint during STS.…”

“…Sixteen reflective markers were attached bilaterally on the posterior superior iliac spine, anterior superior iliac spine, lateral thigh, knee joint, tibia, lateral malleolus, second metatasal head, and calcaneous (Kim et al, 2014). Four reflective markers were attached on the spinous process of the twelfth thorax, first lumbar spine, and 3 ㎝ to the left and right sides of the spinous process of the first lumbar spine (Kim et al, 2014). One marker was attached on the spinous process of the first thoracic spine (T1).…”

“…Frequent increased motion of the lumbar spine with insufficient hip motion may aggravate lower back pain, and restoring coordination of the lumbar spine and hip joint movement could alleviate lower back pain and prevent recurrent lower back pain (Esola et al, 1996;Kim et al, 2014;McClure et al, 1997;Sahrmann, 2002). Although it is important to prevent excessive and frequent flexion of the lumbar spine during STS, no study of methods of preventing excessive flexion of the lumbar spine during STS have been published.…”
