Abstract
Purpose of the study and background
Physical activity and exercise therapy are among the guideline recommendations for the rehabilitation of people with chronic low back pain (CLBP ≥ 3 months); however, patient adherence is often poor. CONNECT is a theory-based communication skills training programme designed to enhance physiotherapists' support of their CLBP patients' psychological needs in order to increase adherence to their home-based rehabilitation programme.
Methods and results
The CONNECT trial [Current Controlled Trials ISRCTN63723433] included six Dublin-area public clinics and their physiotherapists (n = 24) who received eight hours of communication skills training from a psychologist [experimental group] and physiotherapists (n = 26) from six equivalent clinics who formed a treatment as usual pragmatic control condition. New patients (n = 255, 54% female) diagnosed with CLBP and receiving physiotherapy at one of these clinics completed ratings of home-based adherence at 1, 4, 12, and 24 weeks after their initial treatment session; 24 weeks was the primary endpoint. Due to the nature of the intervention, physiotherapists were aware of treatment allocation; patients and assessors were blinded. Intention to treat analysis using a linear mixed model approach indicated that patients in the experimental group rated their home-based adherence significantly higher than patients in the control condition across time-points (P = .01), but the difference was not significant at the 24-week follow-up (P > .05).
Conclusions
The CONNECT intervention had a positive effect on patients' self-rated adherence to home-based rehabilitation for CLBP, but the impact was not maintained over 24 weeks. Further analysis from the CONNECT trial will investigate its effects on pain and function, as well as hypothesised mediators of change.
