Pain coping skills training and lifestyle behavioral weight management in patients with knee osteoarthritis: A randomized controlled study

Pain, 04/18/2012

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:
    • PCST+BWM;
    • PCST–only;
    • BWM–only;
    • 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).

Results

  • 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.
