Temporal relationships between pain, functioning, and human assumed central sensitization in patients with chronic low back pain; a single-case design.

Background: Interdisciplinary pain rehabilitation (IPR) aims to improve functioning in people with chronic low back pain (CLBP), and is not primary aimed at pain reduction. Many patients however also report a decrease in pain. An explanation could be that IPR results in a decrease in Central Sensitization (CS).

Maximal cardiopulmonary exercise test in patients with chronic low back pain: feasibility, tolerance and relation with central sensitization. An observational study.

Purpose: To analyze the feasibility of and pain-related tolerance to a maximal cardiopulmonary exercise test (CPET), and the relationship between the aerobic capacity and central sensitization (CS) in patients with chronic low back pain (CLBP).

Methods: An observational study, combining a cross-sectional and a prospective 24-hour follow-up was performed. Participants underwent a maximal CPET on a cycle ergometer and were assessed with three measures of CS (CS Inventory, quantitative sensory testing and heart rate variability).

Early termination in interdisciplinary pain rehabilitation: numbers, timing, and reasons. A mixed method study.

Purpose: To analyse the number of, timing of, and reasons for early termination of interdisciplinary pain rehabilitation (IPR).

Methods: A multicentre study in two Dutch rehabilitation centres with a mixed method design. Quantitative part: retrospective patient file review of all IPR patients.

Differences in the relationship between psychosocial distress and self-reported disability in patients with chronic low back pain in six pain rehabilitation centers in the Netherlands.

Study Design: A cross sectional multicenter study in six outpatient Rehabilitation Centers (RCs) in the Netherlands.

Objective: This study aims to confirm or refute the finding that a strong relationship exists between psychosocial distress and self-reported disability in patients with nonspecific chronic low back pain (CLBP) by analyzing this relationship in patients with CLBP admitted for treatment in six RCs.

Summary Of Background Data: A strong relationship between psychosocial distress and self-reported disability in patients with CLBP is suggested.
