Pain coping skills training and lifestyle behavioral weight management in patients with knee osteoarthritis: A randomized controlled study
Somers TJ et al. – Interventions teaching overweight and obese osteoarthritis (OA) patients pain coping skills and weight management simultaneously may provide the more comprehensive long–term benefits.Methods
- This study examined the long–term efficacy of a combined pain coping skills training (PCST) and lifestyle behavioral weight management (BWM) intervention in overweight and obese OA patients.
- Patients (n=232) were randomized to a 6–month program of:
- Or standard care control.
- Assessments of pain, physical disability (Arthritis Impact Measurement Scales [AIMS] physical disability, stiffness, activity, and gait), psychological disability (AIMS psychological disability, pain catastrophizing, arthritis self–efficacy, weight self–efficacy), and body weight were collected at 4 time points (pretreatment, posttreatment, and 6months and 12months after the completion of treatment).
- Patients randomized to PCST+BWM demonstrated significantly better treatment outcomes (average of all 3 posttreatment values) in terms of pain, physical disability, stiffness, activity, arthritis self–efficacy, weight self–efficacy, and weight when compared to the other 3 conditions (Ps<0.05).
- PCST+BWM also did significantly better than at least one of the other conditions (ie, PCST–only, BWM–only, or standard care) in terms of psychological disability and pain catastrophizing.
