Randomized Controlled Trial
Effects of Clinic-Based and Telerehabilitation-Based Motor Control Exercises in Individuals with Chronic Low Back Pain - A Randomized Controlled Trial with 3-Month Follow-Up.
To evaluate the effectiveness of clinic-based and telerehabilitation-based motor control exercises in individuals with chronic low-back pain 3 months posttreatment. ⋯ Telerehabilitation-based motor control exercises proved as effective as clinic-based methods in treating chronic low-back pain, offering a viable alternative tailored to individual needs and circumstances.

Recovery quality of transversus abdominis plane block with liposomal bupivacaine after cesarean delivery: A randomized trial.
This study aimed to investigate the effect of liposomal bupivacaine in transversus abdominis plane block (TAP) on recovery quality after cesarean delivery. ⋯ TAP block using either liposomal bupivacaine or a mixture of plain bupivacaine and liposomal bupivacaine provided superior quality of recovery at 24 h after cesarean delivery compared to using plain bupivacaine alone.

Randomized Controlled Trial
Studying the effect of expectations on high-frequency electrical stimulation-induced pain and pinprick hypersensitivity.
Negative expectations can increase pain, but can they promote the development of central sensitization? This study used an inert treatment and verbal suggestions to induce expectations of increased high-frequency electrical stimulation (HFS)-induced pain and assessed their effects on pain ratings during HFS and HFS-induced pinprick hypersensitivity. Fifty healthy volunteers were randomly allocated to either a control group (N = 25) or a nocebo group (N = 25). Participants in both groups received a patch containing water on the right forearm. ⋯ HFS increased pinprick sensitivity but no group differences were found. Because of the lack of differences in expected pain and pain intensity ratings for HFS between groups, no firm conclusions can be drawn regarding their effect on pinprick hypersensitivity. PERSPECTIVE: This study shows that sham treatment combined with verbal suggestions induces a nocebo effect but does not necessarily change expectations and experience of upcoming pain.

Comparative Study
Comparison of Measures of Pain Intensity during Sickle Cell Disease Vaso-Occlusive Episodes.
We aimed to determine the minimal clinically important difference (MCID) in pain severity and agreement between the visual analog scale (VAS) and the verbal numeric rating scale (NRS) in people with sickle cell disease (SCD) experiencing an acute vaso-occlusive episode in the emergency department. In the COMPARE-VOE trial (NCT03933397), participants were administered the VAS (0-100), NRS (0-100), and descriptor scale (a lot better, a little better, same, a little worse, much worse) every 30 minutes while in the emergency department. We analyzed data from 100 participants (mean age 30.2 years; 61% female). ⋯ Despite high correlation, there was considerable variability of agreement between the VAS and NRS scales, indicating that these scales are not interchangeable to assess pain during a vaso-occlusive event. PERSPECTIVE: The MCID in pain severity for individuals with a SCD vaso-occlusive episode using the VAS (8.77 mm) is lower than previously reported, and the MCID for NRS was 8.29. The agreement between the VAS and NRS was determined and the scales cannot be used interchangeably to measure SCD pain intensity.

Targeted muscle reinnervation (TMR) is an effective surgical treatment for neuropathic pain in amputees. Qualitative descriptions of pain, depicted by pain sketches, could enhance the understanding of symptomatic improvement after surgery. Our aim is to assess whether preoperative pain sketches, drawn by lower extremity (LE) amputees, can predict surgical outcomes after secondary TMR surgery. ⋯ In LE amputees who underwent secondary TMR, preoperative pain sketches could serve as a helpful tool in predicting pain outcomes. RP sketches seemed to be associated with worse outcomes and FP sketches with the most improvement.
