A literature review was conducted to compare placebo responses in a recent trial-which implemented an accurate pain reporting (APR) and placebo response reduction (PRR) training program-with placebo responses in similar previous trials in chronic lower back pain (CLBP) that did not use such training. ⋯ These findings are consistent with results from other studies showing that neutralizing subject and study staff expectations of therapeutic benefit can decrease the placebo response in clinical trials. The results of this study suggest training participants and staff to improve pain reporting accuracy, neutralize expectations, and decrease external cues that may bias participants' pain ratings in clinical trials may effectively decrease the placebo response leading to increased assay sensitivity.

The objective of this study was to conduct an updated systematic review of diagnostic criteria for myofascial trigger points (MTrPs) used in clinical trials of physical therapy interventions from 2007 to 2019. ⋯ This systematic review was registered under the Centre for Reviews and Dissemination, PROSPERO number: CRD42018087420.

The objective of this study was to identify and describe long-term trajectories of bothersome pain and activity-limiting pain in a population-based sample of older adults. ⋯ Approximately one half of older adults had a high or increasing probability of long-term bothersome pain, and over one quarter had a high or increasing probability of long-term activity-limiting pain.

Loss-adjusting: Young People's Constructions of a Future Living with Complex Regional Pain Syndrome.
Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that can present specific difficulties when occurring in adolescence. There is limited work exploring future narratives of healthy adolescents, and how these may differ for those who have chronic health conditions, but there is no research on the future narratives of adolescents who have CRPS. ⋯ CRPS may damage the future plans of adolescents. However, being or learning how to be flexible about these goals, may help them to build more positive future narratives.
