Abstract:
[Purpose] This study developed a reciprocal hip exercise using Thera-Band for those with flat lumbar spines and observed changes in standing and movement angles during sit-to-stand. [Participants and Methods] Eleven females participated in this study. The participants performed the reciprocal hip exercise using Thera-Band. [Results] The trunk flexion angle increased significantly after reciprocal hip exercise. The sit-to-stand time after reciprocal hip exercise was significantly faster than that before exercise. [Conclusion] The reciprocal hip exercise would useful for patients with flat back who can then sit and work for long periods.
