Quantitative gait analysis of patients with bilateral hip osteoarthritis excluding the influence of walking speed.

Background: The purpose of this study was to investigate gait characteristics of patients with bilateral hip osteoarthritis (BHO) independent of walking speed.

Methods: We measured gait parameters in 12 BHO patients during free walking activities and in 12 normal adults during both free walking and slow walking activities using a three-dimensional computerized gait analysis system.

Results: Patients with BHO had a lower walking speed, step length, and cadence than normal subjects during free walking.

Effects of disease severity on response to lateral wedged shoe insole for medial compartment knee osteoarthritis.

Objective: To determine the effects of lateral wedged insoles on knee kinetics and kinematics during walking, according to radiographic severity of medial compartment knee osteoarthritis (OA).

Design: A prospective case control study of patients with medial compartment OA of the knee.

Setting: Gait analysis laboratory in a university hospital.
