OBJECTIVE: To assess the effectiveness of a six week cognitive-behavioural group
intervention in patients with knee osteoarthritis pain.
DESIGN: Single-blinded
randomized controlled trial. STUDY SETTING:
Primary care providers in a
medium-sized city in Finland. PATIENTS: A total of 111 participants aged from 35
to 75 with clinical symptoms and radiographic grading (Kellgren-Lawrence 2-4) of
knee osteoarthritis were included. INTERVENTIONS:
In the intervention group, 55
participants attended a cognitive-behavioural training programme for pain
management with six weekly group sessions supervised by a psychologist and a
physiotherapist. Concurrently, they and the 56 participants of the control group
continued in ordinary GP care that was not altered by the study. MAIN MEASURES:
The primary outcome on three-month and 12-month follow-up was the Western Ontario
and McMaster Universities (WOMAC) Osteoarthritis index pain subscale. Secondary
outcome measures included self-reports of pain and physical function,
health-related quality of life, and a comprehensive set of psychological
questionnaires. RESULTS:
Mixed model results showed no significant differences
between the intervention and control group for any measures of pain or function.
A significant difference between the groups was found in the Pain Self-Efficacy
Questionnaire (Pr = 0.022) in favour of the control group, and in the RAND-36
emotional well-being subscale in favour of the intervention group (Pr = 0.038).
Conventional group comparisons of mean follow-up values showed no significant
differences in any of the outcome variables. CONCLUSION: This trial could not
confirm the hypothesized advantage of a cognitive-behavioural training programme
over ordinary GP care in knee osteoarthritis pain patients. TRIAL REGISTRATION:
