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.

Individual understanding of and expectations for chronic pain treatment can influence treatment adherence and thus success, but little is known about these critical factors in parents and children presenting with pain-predominant functional gastrointestinal disorders. The aim of this study was to identify parent and patient understanding of pain-predominant functional gastrointestinal disorders, expectations for treatment, and interventions utilized before presenting to a multidisciplinary clinic. ⋯ Participants were knowledgeable regarding chronic pain, but still indicated that receiving a definite diagnosis would be the most helpful intervention. Most had tried multiple interventions and did not believe that further medication, testing, or surgery would solve their pain. Instead, parents presenting at this Functional Abdominal Pain Program appeared most hopeful about the benefits of multidisciplinary treatment approaches including psychological interventions, a focus on activity and functioning, and complementary and alternative medicine interventions.

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.

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.
