The results showed that short-term adherence to wearable activity trackers was high in this population (92 percent at ten weeks). Regarding the effect on increasing physical activity levels, results showed an interesting increase of 1,520 steps per day between groups using the tracker and groups without the tracker. An effect was also observed on the time spent in moderate to vigorous physical activity with a 16 min daily difference between groups.
However, no significant results were found for the main outcomes in prolonged follow-up after the end of the intervention period. Increase in physical activity was not correlated with an increase in short-term symptoms, although pain increased during long-term interventions.
Wearable activity trackers appear to be a promising strategy to improve physical activity for patients with rheumatic and musculoskeletal diseases.
