Interventions with a clear focus on achieving behaviour change are important for maintaining training-related gains in people with chronic obstructive pulmonary disease: a systematic review.

Questions: In people with chronic obstructive pulmonary disease (COPD) who complete an exercise training program (ETP) offered at a sufficient dose to result in training-related gains, to what extent are these gains maintained 12 months after program completion? Do variables such as the application of behaviour change techniques moderate the maintenance of these training-related gains?

Design: Systematic review, meta-analysis and meta-regression of randomised controlled trials.

Participants: People with stable COPD.

Intervention: Trials were included if they applied ≥ 4 weeks of a whole-body ETP and reported outcome data immediately following program completion and 12 months after initial program completion.

Tactile acuity improves during acute experimental pain of the limb.

Introduction: Chronic pain is associated with poor tactile acuity, commonly measured with the 2-point discrimination (TPD) test. Although poor tactile acuity across chronic pain conditions is well established, less is known in acute pain.

Objective: Recent conflicting findings in experimentally induced neck and back pain led us to conduct a TPD investigation in experimentally induced limb pain.
