The aim of this study was to evaluate the oxygen cost of gait and measure physical activity profiles, including time spent sedentary, in people with rheumatoid arthritis (RA) and matched controls. We recruited 19 people with RA and 19 controls matched for age, sex, and body mass index (BMI). Demographic details and clinical characteristics of the RA population were recorded. Oxygen uptake per metre walked (oxygen cost) was measured in the laboratory using a portable gas analyser.
