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.

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 evaluate the long-term predictive value of the Danish Whiplash Group Risk Assessment Score (DWGRAS) with 7 risk strata. ⋯ Internal and long-term validation of DWGRAS was performed, but a low response rate indicates that results should be interpreted with caution. Furthermore, external validation needs to be done in long-term studies. An receiver operating characteristics curve of 0.73 (95% confidence interval 0.67; 0.79) predicting daily or weekly whiplash-related disability after 12 to 14 years was found using the DWGRAS risk score.

High risks of falls have been reported in older adults with chronic pain but chronic pain similarly affects adults of all ages. This cross-sectional study aimed to determine the prevalence of falls and associated risk factors in adults of all ages living with chronic pain. ⋯ A high prevalence of falls was found independent of age for adults with chronic pain. Although the risk of falls may increase with age, lower physical function and more pain sites are better indicators for falls. A better understanding of circumstances and consequences of falls in all adults with chronic pain is warranted.
