There has been varied success of behaviour change interventions in promoting physical activity behaviour in people who have RA .
Research has shown that people who have rheumatoid arthritis ( RA ) do not usually participate in enough physical activity to obtain the benefits of optimal physical activity levels , including quality of life , aerobic fitness and disease-related characteristics .

The value of a continuous ambulatory activity monitor to quantify the amount and intensity of daily activity in patients with rheumatoid arthritis.
OBJECTIVE To examine the reliability , validity , and responsiveness of a continuous ambulatory activity monitor in patients with rheumatoid arthritis ( RA ) . METHODS Forty-one patients with RA , participating in a r and omized controlled trial examining the effect of an intensive exercise program  , were assessed by means of the  Dynaport ADL ( activities of daily living ) monitor ( AM ) .  The time spent on activities ( locomotion , st and ing , and active sitting ) during 24 hours and the intensity of trunk movement during these activities were recorded . To determine test-retest reliability 20 patients were reassessed with the AM one week after the first assessment . Construct validity of the AM was determined by comparing the AM results with physical fitness measures ( muscle strength , endurance , joint mobility ) , disease activity , and functional status . As well , 37 patients were assessed 18 months after the first assessment to determine responsiveness . RESULTS All AM measurements showed satisfactory test-retest reliability ( ICC 0.63 - 0.76 ) . AM measures were significantly associated with physical fitness , functional status , and disease activity , indicating construct validity of the AM . The AM could discriminate between patients with improvement and deterioration in physical fitness , indicating sufficient responsiveness of AM variables . CONCLUSION This study shows the value of an ambulatory activity monitor to quantify both the amount and intensity of physical activity of patients with RA during a day in their own environment . The ambulatory activity monitor seems to be a promising instrument for research into rehabilitation of patients with RA
