Range of Hip Joint Motion and Weight of Lower Limb Function under 3D Dy-namic Marker / 法医学杂志

ABSTRACT

Objective To explore the range of reasonable weight coefficient of hip joint in lower limb function. Methods When the hip joints of healthy volunteers under normal conditions or fixed at three different positions including functional, flexed and extension positions, the movements of lower limbs were recorded by LUKOtronic motion capture and analysis system. The degree of lower limb function loss was calculated using Fugl-Meyer lower limb function assessment form when the hip joints were fixed at the aforementioned positions. One-way analysis of variance and Tamhane's T2 method were used to proceed statistics analysis and calculate the range of reasonable weight coefficient of hip joint. Results There were significant differences between the degree of lower limb function loss when the hip joints fixed at flexed and extension positions and at functional position. While the differences between the degree of lower limb function loss when the hip joints fixed at flexed position and extension posi-tion had no statistical significance. In 95％ confidence interval, the reasonable weight coefficient of hip joint in lower limb function was between 61.05％ and 73.34％. Conclusion Expect confirming the rea-sonable weight coefficient, the effects of functional and non-functional positions on the degree of lower limb function loss should also be considered for the assessment of hip joint function loss.
