title: Ambulatory activity as an objective and quantifiable measure of nonsteroidal therapy.
abstract: OBJECTIVE
  To quantify any increase in short term spontaneous ambulatory activity resulting from the use of nonsteroidal antiinflammatory drugs (NSAID) in patients with rheumatoid arthritis (RA).
  
  
  METHODS
  Double blind placebo controlled crossover study of 8 women with RA using conventional assessments and the Numact activity monitor.
  
  
  RESULTS
  Patients' ambulatory activity was 50% greater during NSAID treatment compared to placebo treatment. Effect size calculated at 0.62, suggesting good sensitivity to change. The increased activity occurred late morning.
  
  
  CONCLUSIONS
  Spontaneous ambulatory activity is an objective and relevant measure of disability.
