Randomized Controlled Trial Comparative StudyAdductor Canal Block Versus Femoral Nerve Block for Analgesia After Total Knee Arthroplasty: A Randomized, Double-blind Study.
Quadriceps strength is better preserved after adductor canal block for total knee arthroplasty than femoral nerve block with similar analgesic effect.

ReviewA Scoping Review of the Evidence for Teaching Ultrasound-Guided Regional Anesthesia.
A scoping review was performed to assess published evidence regarding how best to teach ultrasound-guided regional anesthesia (UGRA). The literature search yielded 205 articles, of which 35 met the inclusion criteria. Current literature on the topic can be divided into 3 main themes: the development of motor skills, learning and teaching sonoanatomy, and understanding of the requirements for establishing a UGRA education program and evaluation. We discuss the current status and future direction of research on UGRA training.

ReviewMusculoskeletal Pain, Fear Avoidance Behaviors, and Functional Decline in Obesity: Potential Interventions to Manage Pain and Maintain Function.
Individuals with musculoskeletal pain exhibit abnormal movement patterns, including antalgic gait, postural dysfunction, increased thoracolumbar stiffness, decreased proprioception, and altered activation of abdominal and extensor muscles. Additionally, aberrant or increased biomechanical forces over time produce joint or structural damage that results in pain. A large body habitus resulting from excessive weight can accelerate these musculoskeletal complaints. ⋯ Morbid obesity is a medical condition that alters biomechanical forces on the tissues of the body. This condition provides the opportunity to examine accelerated development of musculoskeletal pain syndromes and etiology. The proposed therapeutic interventions can have multiple benefits in the obese population including weight loss, improved psychological outlook and self-efficacy, reduced kinesiophobia levels, reduced risk of functional dependence, and improved quality of life.

Randomized Controlled Trial Comparative StudyA Dose-Ranging Study of 0.5% Bupivacaine or Ropivacaine on the Success and Duration of the Ultrasound-Guided, Nerve-Stimulator-Assisted Sciatic Nerve Block: A Double-Blind, Randomized Clinical Trial.
Before bifurcation, the sciatic nerve is composed of 2 component nerves encased in a common investing extraneural layer (CIEL). We examined the effect of various volumes injected beneath the CIEL on the success and duration of sciatic nerve block. ⋯ Injecting 10 mL of 0.5% bupivacaine or ropivacaine below the CIEL produces comparable onset and duration of sensory and motor blockade as volumes as large as 30 mL.

Observational StudyValidation of the English Language Pain Sensitivity Questionnaire.
The Pain Sensitivity Questionnaire (PSQ) is predictive of pain-related responses to experimental stimuli in German-speaking individuals. Here, we explored the validation of the English translation of the PSQ (PSQ-E). ⋯ The study demonstrated that a significant correlation exists between the PSQ-E and clinically relevant pain ratings. This study validates the PSQ-E both in terms of measuring pain sensitivity and as possible means of recognizing patients with high pain sensitivity. Defining this subset of patients may have clinical utility in the future.
