Abstract:
BACKGROUND:Total hip arthroplasty is known to be a successful surgical procedure to al eviate hip pain and to regain gait ability, but there are many debates on whether patients’ gait could reach a normal level several years later. OBJECTIVE:To investigate spatiotemporal parameter characters of lower extremities in patients during walking in sequela period fol owing unilateral total hip arthroplasty, and to probe into patients’ walking abilities.
METHODS:In accordance with the method of Case Database Data Analysis detected by Motion Reconstruction Laboratory, 14 patients at 5-10 years after total hip arthroplasty served as the experimental group, and 14 matched healthy persons served as the control group. Gait parameters of lower extremities during walking were col ected by Vicon Nexus. Spatiotemporal parameter characters of lower extremities during gait cycle were analyzed by using Polygon.
RESULTS AND CONCLUSION:Compared with the control group, walking speed, cadence, stride length and step length decreased, but double support and opposite foot off increased on both affected and unaffected sides in the experimental group (P<0.05). Both stride time and step time of the operated lower extremities increased (P<0.05). Foot off of non-operated lower extremities increased (P<0.05). There was no significant difference in al spatiotemporal parameters between operated and non-operated lower extremities (P>0.05). The results suggested that gaits of patients showed good gait symmetry at 5-10 years after surgery. However, they do not reach the level that observed in healthy subjects, and walking ability was poorer than normal persons. Systematic rehabilitation training is needed to improve walking ability.
