Gait Parameters In Patients With Knee Osteoarthritis Before High Tibial Osteotomy
Proceedings of the 3rd World Congress of the International Society of Physical and Rehabilitation Medicine ISPRM(2005)
摘要
Ten female patients aged 45-63 years before high tibial osteotomy and ten age- and gender-matched controls participated in the study. Twenty passive reflective markers on the standard points of the trunk and lower extremities as viewed by the six opto-electronic cameras were digitized by the ELITE motion analyzer (BTS, Italy) during "free" and fast walking. The temporal and distance parameters of gait were analyzed. There was noted a prolongation (p < 0.001) of stance time in the involved leg of patients with knee OA as compared with the uninvolved leg (11.0%) and to controls (9.7 and 11.2% for right and left leg, respectively) during "free" walking. The double support time in patients was significantly shorter (P < 0.05) in the involved leg as compared with the uninvolved leg (1.2%) and to controls (1.8 and 1.5% for right and left leg, respectively). Patients demonstrated a prolongation (p < 0.05) of stride time for both legs and lengthening of step width (38.4%, p < 0.01) and a decrease of walking speed in comparison to controls during fast walking.
