OBJECTIVE: To assess the reliability and responsiveness of gait speed,
cadence and stride length at two self-selected speeds (SSS) in subjects
with rheumatoid arthritis (RA). METHODS: Thirty-one subjects with RA were
assessed on three occasions. At each assessment session, subjects were
asked to self-report walk pain on visual analogue scales, rate physical
function using the Health Assessment Questionnaire, and walk five times at
both a normal SSS and a fast SSS along an 8 m electric footswitch walkway.
RESULTS: Despite stability of pain and physical function, there were
significant gait changes from the first to the second assessment session at
the normal SSS, although this 'learning' effect was not evident at either
SSS between the second and the third assessment session. CONCLUSION: If the
recommended protocol is followed, quantitative gait variables can provide
reliable and responsive outcome measures in this population for use in
evaluating therapeutic interventions.
