Purpose: Despite panoramic ultrasound imaging (US) is a promising advance for the morphological and histological assessment of large musculature which cannot be entirely assessed using B-mode, there is no evidence assessing if this technology produces muscle deformation during imaging acquisition. We aimed to analyze differences in size, shape and brightness descriptors between B-mode and panoramic US images and to assess the concordance between both methods. Methods We analyzed size (cross-sectional area and perimeter), shape (circularity, aspect ratio and roundness) and brightness (mean echo-intensity) features of cervical multifidus (CM) and short rotators (SR) in 46 healthy volunteers. Images were acquired in B-mode and extended field-of-view mode. For validity analysis, mean differences between methods were calculated. For agreement analysis, intraclass correlation coefficients (ICCs), standard error of measurements (SEM), minimal detectable changes (MDC) and coefficient of variation (CV%) were calculated. Results: All parameters showed no significant differences between both methods for either CM or SR (P > 0.05). Panoramic US showed excellent concordance with B-mode for assessing all CM parameters (all ICCs > 0.9), while for SR the agreement ranged from good-to-excellent (ICC from 0.861 to 0.978). Conclusion: Panoramic US seems to be a valid tool for assessment of muscle size, shape and brightness as no deformation in comparison with B-mode images was seen. Further research is needed to corroborate these findings comparing panoramic US imaging with Gold Standard methods.
Ultrasound-guided percutaneous electrical nerve stimulation versus surgery for women with unilateral carpal tunnel syndrome: A randomized parallel-group trial

ObjectiveThe aim of this clinical trial was to compare the outcomes of the application of ultrasound-guided percutaneous nerve stimulation (PENS) targeting the median nerve versus surgery for improving pain and function in women with CTS.MethodsIn this randomized parallel-group trial (ClinicalTrials.gov, NCT04246216), 70 women with CTS were randomly allocated to either PENS (n = 35) or surgery (n = 35) group. Hand pain intensity (mean pain and the worst pain experienced) was the primary outcome. Functional status and symptoms severity (Boston Carpal Tunnel Questionnaire, BCTQ) and self-perceived improvement (Global Rating of Change, GROC) were the secondary outcomes. Outcomes were assessed at baseline and 1, 3, 6 and 12 months after each intervention. Analysis was performed with intention to treat with mixed ANCOVAs adjusted for baseline outcomes.ResultsAnalyses showed an adjusted advantage for PENS at 1 (Δ −2.0, 95% CI −2.9 to −1.1) and 3 (Δ −1.4, 95% CI −2.3 to −0.5) months for mean pain, at 1 (Δ −2.2, 95% CI −3.3 to −1.1), 3 (Δ −1.75, 95% CI −2.9 to −0.6) and 6 (Δ −1.7, 95% CI −2.8 to −0.6) months in the worst pain intensity, and at 1 (Δ −0.95, 95% CI −1.1 to −0.8), 3 (Δ −0.55, 95% CI −0.8 to −0.3) and 6 (Δ −0.4, 95% CI −0.6 to −0.8) months in function. Both groups exhibited similar changes in symptom severity. Both groups reported similar improvement at 12 months in all outcomes. Symptoms and function improved in both groups, with PENS leading to better short-term outcomes than surgery.ConclusionThis clinical trial confirms that PENS applied with current understanding of pain mechanisms in CTS is as useful as surgery in women with CTS without denervation. The potential placebo effect of both interventions should not be ignored.SignificanceThe application of percutaneous nerve stimulation was more effective at short-term, but similar effective at mid and long-term, than surgery in women with carpal tunnel syndrome.
