OBJECTIVE: To investigate the magnitude of change at different time points in
measures of gait symmetry, gait velocity and self-reported function following
total hip replacement. Longitudinal with test occasions pre-surgery and
3, 6 and 12 months post-surgery.
Thirty-four patients with hip
osteoarthritis (mean age 63 years, standard deviation 11 years). METHODS:
Subjects walked back and forth along a 7-m walkway at slow, preferred and fast
speed. Anteroposterior, vertical and mediolateral trunk symmetry was assessed by
accelerometry, while single support symmetry, step-length symmetry and gait
velocity was simultaneously assessed by an electronic walkway. Self-reported
function was assessed by Hip disability and Osteoarthritis Outcome Score. Gait
symmetry data were normalized for gait velocity. Changes between test occasions
were reported as effect size. RESULTS: All measures showed effect sizes > 0.30
from pre-operative to 12-months postoperative assessments
