Objective: The purpose of this study was to clarify the characteristic of pain catastrophizing and the relationship between pain catastrophizing and related factors in preoperative patients with lumbar spinal stenosis.
Methods: This cross-sectional study included 45 preoperative patients (25 males, 20 females; mean age 68.4 years) with lumbar spinal stenosis. Demographic data, leg pain, back pain, the scores on the Pain Catastrophizing Scale (PCS) and the Timed Up and Go test, walking velocity, grip strength, muscle mass, and walking distance were assessed. Patients were divided into two groups based on their PCS score: the higher PCS group (PCS score ≥ 30) and the lower PCS group (PCS score < 30).
Results: The mean PCS score was 34.7. In the multivariate analysis adjusted for confounding factors, walking velocity was a significant relevant factor for PCS in these patients (OR = 0.036; 95% CI, 0.001– 0.937; p = 0.046).
Conclusions: These findings suggested that walking velocity may be related to pain catastrophizing in preoperative patients with lumbar spinal stenosis.
