Changes in gait symmetry, gait velocity and self-reported function following total hip replacement.

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.

Design: Longitudinal with test occasions pre-surgery and 3, 6 and 12 months post-surgery.

Subjects: Thirty-four patients with hip osteoarthritis (mean age 63 years, standard deviation 11 years).

Criteria of gait asymmetry in patients with hip osteoarthritis.

Gait symmetry is often a goal for physiotherapy in patients with hip osteoarthritis and after total hip replacement. However, there is no agreement on criteria for pathological gait asymmetry. In this study we investigated discriminative abilities of trunk and footfall gait symmetry measures, and thereafter assessed whether a 10% cutoff value is valid as a general criterion of pathological gait asymmetry across measures.

Gait variability measures may represent different constructs.

Many measures of gait variability have been reported, but the degree to which such measures are associated and thus represent a common construct is inconclusive. The purpose of this paper is to establish construct validity of commonly used spatio-temporal footfall variability and trunk variability measures taking into account the effect of measurement error. Twenty-three older individuals, aged 80+/-5 years performed four repeated walks at preferred speed, 0.

Gait patterns in subjects with rheumatoid arthritis cannot be explained by reduced speed alone.

The aim of this study was to investigate the characteristics of gait in subjects with rheumatoid arthritis (RA) by comparing gait parameters obtained from these subjects and controls. Seventeen subjects with RA in functional class II (mean age 51.1 years, S.
