If the hip joint continues to internal rotation, the knee joint may occur genu valgus deformity and the foot arches may collapse to flat, as resulting decrease functional activity like gait. The purpose of this study was investigated to the effect of a newly designed hip joint angle adjuster orthosis to correct the abnormal internal rotational of the hip joint and the abnormal alignment of the lower limb. Twenty five patients who had internal rotation angle of the hip joint greater than the normal angle of hip joint were applied to this research. Gait factors were used by the GaitRite device and the alignment of the lower limb were measured using a ABW-mapper device before and after intervetion, respectively. The statistical analysis was performed by a paired t-test. As a result, the gait velocity (28.70±19.90 m/sec)(p=.000) and cadence (7.45±12.71 m/sec)(p=.017) were significantly improved than before the intervention in the gait factors. The maximum rotation angle of the femur (20.08±5.54)(p=.000) has significantly improved than before the intervention in the lower limb alignment. This research suggest that newly designed hip joint angle adjuster orthosis may be effective gait velocity and the cadence in gait, and rotation angle of the femur on the lower limb symmetry.
