Objectives: This study aimed to investigate the safety and efficacy of high-definition transcranial alternating current stimulation (HD-tACS) to the left primary motor cortex (M1) in the treatment of fibromyalgia (FM) patients. Methods: In this randomized, double-blind, sham-controlled clinical trial, patients with FM were recruited in a teaching hospital. Thirty-eight patients were randomized to active HD-tACS (n = 19) or sham stimulation (n = 19). Active stimulation included a daily session of 20-min stimulation of 1 mA HD-tACS over the left M1 for ten sessions in two weeks. The primary outcome was the change in pain intensity and quality of life, assessed using the numeric rating scale (NRS) and the fibromyalgia impact questionnaire (FIQ) at baseline and after two weeks of treatment. Secondary outcomes included other core symptoms of FM (psychological distress, sleep quality, hyperalgesia measured by pressure pain threshold) and changes in biomarkers’ total Tau and Aβ1-42. All analyses were based on intention-to-treat for a significance level of p < 0.05. Results: Of the 38 randomized patients, 35 completed the study. After two weeks, HD-tACS induced a significant reduction in FIQ score post-treatment. However, there were no significant differences in NRS and FIQ scores compared to sham stimulation. Most adverse events were mild in severity. Nevertheless, one patient receiving HD-tACS attempted suicide during the trial. Conclusions: These results suggest that HD-tACS may effectively reduce pain, psychological distress, and symptom impacts in FM patients. However, we found no significant differences between the two groups. Future studies investigating HD-tACS in FM are warranted.
Objectives: Competency-based public communication skills are not systematically taught in most medical curricula, reflecting a gap between medical knowledge and holistic patient care as trainees transition into clinicians. We sought to investigate the efficacy of technology, entertainment, and design (TED) talks in postgraduate year (PGY) training programs. Methods:The authors organized an official internal TEDx event in which six PGY trainees volunteered as speakers. Two experienced physicians and two administrators also participated as speakers to provide trainees a didactic shadow learning experience. The remaining PGY trainees, along with clerks, physicians, nurses, pharmacists, and administrators, attended the conference. Before the event, speakers undertook individual training sessions and learned the principles of the presentation structure and storytelling mode. At the end of the event, a survey evaluating overall satisfaction in communication skills and professionalism was administered to all of the attendees.Results: Survey participants totaled 104, with a response rate of 97.2%. TEDx talks improved trainees' levels of patient care, communication, and professionalism. Speakers reported the high level of satisfaction with the event (mean 4.96 on a 5-point Likert scale; standard deviation 0.20). Participants agreed that the shadowing experience was useful and that the event encouraged them to pursue interests outside the medical field.Conclusions: This study highlights that TED is successful in terms of participant satisfaction and training in communication and professionalism. Engaging and training PGY trainees through TED-style events could bridge the gap between acquired knowledge and professional competencies. The authors recommend the implementation of TED-style events in medical training programs.
