Pressure Pain Tolerance Predicts the Success of Emotional Awareness and Expression Therapy in Patients with Fibromyalgia.
Quantitative sensory testing may help predict treatment responses in individuals with chronic pain. Our objective was to determine whether evoked pain sensitivity at baseline predicted preferential treatment responses to either emotional awareness and expression therapy (EAET) or cognitive behavioral therapy (CBT) in individuals with fibromyalgia (FM). ⋯ Normal levels of pressure pain tolerance at baseline predicted greater improvement in clinical pain severity after EAET than CBT. Quantitative sensory testing may provide insights about individual responses to psychologically based therapies for individuals with chronic pain.

Randomized Controlled Trial
Comparison of Adductor Canal Block and Femoral Triangle Block for Total Knee Arthroplasty.
Adductor canal block (ACB) could provide effective postoperative pain control for patients after total knee arthroplasty (TKA). However, some authors pointed out that the ACB as originally described may be more similar to a femoral triangle block (FTB). Recent neuroanatomic evidences made the authors conjecture that the "true" ACB would provide superior analgesia compared with FTB. Therefore, the study was designed to determine the hypothesis that postoperative analgesia after TKA could be improved by a "true" ACB compared with FTB. ⋯ ACB can provide superior analgesia and preserve more quadriceps strength than FTB. ACB facilitates functional recovery in the early stages and is compatible with the highly recognized concept of rapid rehabilitation, which should be promoted in the clinic.

This study aimed to develop a method that objectively measures the clinical benefits of ketamine infusions to treat complex regional pain syndrome (CRPS), thus making it possible, for the first time, to determine the optimal dosing of ketamine and duration of treatment to treat CRPS. ⋯ Our findings suggest that 4 days of treatment are sufficient for the treatment of CRPS of the lower extremities. For the upper extremities, >4 days may be required. Our study is the first to utilize quantitative sensory testing to direct the treatment of a chronic pain disorder.

The current study assessed the role of hypervigilance for bodily sensations in the back in long-term low back pain problems. ⋯ The current study confirmed that individuals preparing a movement attended more toward somatosensory stimuli at the lower back when anticipating back pain during the movement, as measured by the N96 SEP. However, no differences were found between participants with chronic low back pain or recurrent low back pain, or the pain-free controls.

The original Letter to the Editor prepared by Jones et al was based on the initial electronic version then contained several important procedural errors that resulted in erroneous conclusions as noted by Jones et al in their original Letter. Subsequently, the authors of the Letter to the Editor were notified of the corrections and they then prepared the revised Letter to the Editor published here. Jones et al did note a remaining error in Table 5 of their corrected manuscript. Based on Jones et al's observation, Lenoir et al were notified of an error on Table 5 and have addressed this in the current version of their paper published in this issue. We appreciate the input of the authors of the letter and the positive response of the author(s) of this article. Dennis C. Turk, PhD Editor-in-Chief OBJECTIVE:: Acupuncture is a common modality in the therapy of musculoskeletal disorders. The evidence for acupuncture has been examined frequently, but a clear synthesis of previous research is currently lacking. This meta-analysis aimed to summarize the evidence for nonimmediate effects of acupuncture on pain, functionality, and quality of life in patients with musculoskeletal disorders, when compared with sham acupuncture. ⋯ A significant difference in therapy effect, favoring acupuncture, was found for pain at <1 month, 1 to 3 months, and 3 to 6 months, as well as on quality of life at <1 month, and on functionality at <1 month and 1 to 3 months.
