Pain Catastrophizing Associated With Quality of Life in Hip Osteoarthritis
Study participants were assessed for pain intensity, pain catastrophizing, range of hip motion, gait speed, and quality of life.
Pre-surgical pain catastrophizing may be independently associated with quality of life in patients with severe hip osteoarthritis, according to a study published in Pain Medicine.
A total of 70 patients (median age, 68; 89% women) with severe hip osteoarthritis consecutively enrolled at a tertiary clinic and scheduled for primary unilateral total hip arthroplasty were included in this cross-sectional study. Study participants were assessed for pain intensity, pain catastrophizing, range of hip motion, gait speed, and quality of life, using the EuroQOL-5 Dimensions questionnaire, the Japanese Orthopedic Association Hip Disease Evaluation Questionnaire, and a dissatisfaction visual analog scale.
The median score on the Pain Catastrophizing Scale was 26 out of 52 points. Each quality of life scale evaluated in this study was found to be independently associated with pain catastrophizing scores (correlation coefficient, >0.4). Results of the EuroQOL-5 Dimensions questionnaire were found to be associated with extension of the unaffected side, pain intensity on both sides, pain catastrophizing score, and 10-meter gait speed, in a multiple regression analysis.
Results on the Japanese Orthopedic Association Hip Disease Evaluation Questionnaire were found to be associated with pain levels on both sides, pain catastrophizing score, and 10-meter gait speed. Levels of dissatisfaction evaluated using a visual analog scale were associated with age, flexion and extension of both hips, pain intensity on the affected side, and pain catastrophizing score.
Study limitations include its small sample size.
“[I]t is important to assess pain catastrophizing in patients with chronic pain and severe osteoarthritis, and … pain-related psychological constructs need to be considered when treating patients with severe osteoarthritis,” noted the study authors.
