There is very limited evidence for the effectiveness of IDIs on PA and HRQoL in RA and JIA and no evidence for their effectiveness in PsA or AS
The aim of this systematic review was to evaluate the evidence from r and omised controlled trials ( RCTs ) evaluating the effectiveness of interactive digital interventions ( IDIs ) for physical activity ( PA )  and  health related quality of life ( HRQoL )  in people with Inflammatory Arthritis [ rheumatoid arthritis ( RA ) , juvenile idiopathic arthritis ( JIA ) axial Spondyloarthritis ( AS ) and psoriatic arthritis ( PsA ) ] .
Principles of evidence-based medicine.
Evidence -based medicine integrates clinical expertise , patients ' values and preferences , and the best available evidence from the medical literature . Evidence -based orthopedics is a model to assist surgeons to improve the process of asking questions , obtaining relevant information efficiently , and making informed decisions with patients . With an increasing appreciation for higher levels of evidence , orthopedic surgeons should move away from lower forms of evidence . The adoption of r and omized trials and high- quality prospect i ve studies to guide patient care requires 2 prerequisites : ( 1 ) greater appreciation for the conduct of r and omized trials in orthopedics and ( 2 ) improved education and training in evidence -based method ologies in surgery
