Abstract

Rheumatoid arthritis patients alter their gait pattern to compensate for painful foot symptoms. The centre of pressure may be a useful indicator of these altered loading patterns. Our purpose was to undertake a comparison of the regionalised duration and velocity of the centre of pressure between rheumatoid arthritis patients with foot impairments and healthy able-bodied adults. The progression of the centre of pressure through the foot, heel, midfoot, forefoot and toe regions was measured using an EMED-ST pressure platform. Patients walked at self selected cadence. Variables analysed were the average and maximum velocity and the duration of the centre of pressure (as % stance). Alteration of the foot loading patterns in patients with rheumatoid arthritis can be characterised by changes to the centre of pressure patterns. Off-loading the painful and deformed forefoot was a characteristic feature in this patient cohort.
