Using magnetic resonance imaging to measure the depth of acupotomy points in the lumbar spine: A retrospective study

Simultaneous monitoring of the human brain, spinal cord, and cauda equina activity for movement control: An fNIRS approach

Brain‒spinal cord‒cauda equina interactions are essential for controlling lower body movement. However, current monitoring approaches for spinal and caudal activity are limited to use without body movement and to processing via batches of data. Here, we present a novel optical method based on functional near-infrared spectroscopy that enables simultaneous tracking of human brain-spinal cord-cauda equina hemodynamics during body movement. We first developed a support frame for positioning optical emitters and receivers along the spinal canal to maximize spatial resolution and identify the optimal distance between them. We tested the methodology at this optimal emitter-detector distance by assessing the spatiotemporal activation of the motor clusters associated with human ankle extension-flexion movement in the brain, spinal cord, and cauda equina. These brain and spinal clusters are shown to be functionally connected and comparable to those identified by invasive methods during surgical operations. These findings suggest that hemodynamic responses reflect synchronous neural activity in the human brain-spinal cord-cauda equina system for hindlimb movement control.

A case report on hemopneumothorax caused by acupuncture at Huatuo-Jiaji points

Acupuncture is generally safe; however, severe side effects, such as syncope and pneumothorax (PTX), have sometimes been reported. No cases of hemopneumothorax following acupuncture have been reported in Korea. This study reports a case of progression and prognosis of hemopneumothorax after acupuncture in a patient who visited a hospital for digestive disorders and underwent acupuncture treatment at the Huatuo-Jiaji points to control the autonomic nerves. The patient complained of shortness of breath and chest pain after acupuncture. However, neither the patient nor the doctor suspected PTX. Chest radiography, conducted after a day, confirmed hemopneumothorax of the right lung, and the patient was immediately hospitalized. During hospitalization, oxygen therapy and medication were administered, and the patient was discharged 6 days later. However, PTX recurred, and the patient was rehospitalized. The patient was discharged after 4 days, and it was confirmed that he was completely cured, as evident from both radiation findings and patient symptoms on day 20. This study demonstrates that physicians should pay more attention to and be aware of PTX and its symptoms when performing acupuncture on the thoracic chest.

Effectiveness of Acupotomy Combined with Epidural Steroid Injection for Lumbosacral Radiculopathy: A Randomized Controlled Pragmatic Pilot Study

Background and Objectives: This pilot study aimed to evaluate the clinical effectiveness, cost-effectiveness, and safety of acupotomy combined with epidural steroid injection (ESI) in lumbosacral radiculopathy and examine its feasibility for the main study. Materials and Methods: This randomized, controlled, two-arm, parallel, assessor-blinded, pragmatic study included 50 patients with severe lumbosacral radiculopathy who had insufficient improvement after an ESI. Patients were randomized (1:1 ratio) into a combined treatment (acupotomy + ESI, experimental) and an ESI single treatment (control) group. Both groups underwent a total of two ESIs once every 2 weeks; the experimental group received eight additional acupotomy treatments twice a week for 4 weeks. Types of ESI included interlaminar, transforaminal, and caudal approaches. Drugs used in ESI comprised a 5-10 mL mixture of dexamethasone sodium phosphate (2.5 mg), mepivacaine (0.3%), and hyaluronidase (1500 IU). The primary outcome was the difference in changes from baseline in the Oswestry Disability Index (ODI) scores between the groups at weeks 4 and 8. The incremental cost-utility ratio (ICUR) was calculated to evaluate the cost-effectiveness between the groups. Adverse events (AEs) were assessed at all visits. Results: Mean ODI scores for the experimental and control groups were -9.44 (95% confidence interval [CI]: -12.71, -6.17) and -2.16 (95% CI: -5.01, 0.69) at week 4, and -9.04 (95% CI: -12.09, -5.99) and -4.76 (95% CI: -7.68, -1.84) at week 8, respectively. The difference in ODI score changes was significant between the groups at week 4 (p = 0.0021). The ICUR of the experimental group versus the control group was as economical as 18,267,754 won/quality-adjusted life years. No serious AEs were observed. Conclusions: These results demonstrate the potential clinical effectiveness and cost-effectiveness of acupotomy combined with ESI for lumbosacral radiculopathy and its feasibility for a full-scale study. Larger, long-term follow-up clinical trials are needed to confirm these findings.

Implementation of Objective Structured Clinical Examination on Diagnostic Musculoskeletal Ultrasonography Training in Undergraduate Traditional Korean Medicine Education: An Action Research

This study aimed to report the specific methods and investigate the educational effects of diagnostic musculoskeletal ultrasound training and the Objective Structured Clinical Examination (OSCE) for traditional medicine students. Scanning volar wrist and diagnosing carpal tunnel syndrome were selected for musculoskeletal ultrasound to train students to use the basic functions of the ultrasound device and scan various structures including tendons, nerves, and arteries. The students were divided into two groups: one group had 8 weeks of training with mock OSCE experience and received feedback about their scan images, and the other group had 3 weeks of training with flipped learning. The OSCE was implemented on the last day of the training. The subjective learning outcomes were analyzed as students’ evaluation with a 5-point scale, and the objective learning outcomes were analyzed using OSCE scores evaluated with a pre-validated checklist. Of the 111 students, 60 (54.1%) responded to the questionnaire. Overall satisfaction with this ultrasound training was high (4.5 ± 0.60). The average OSCE score in the 8-week group was significantly higher than that in the 3-week group. The students’ self-assessment showed no significant differences between the two groups. Proficiency in using ultrasound is affected by the practice time and feedback. Ultrasound training should be further expanded as a required curriculum to meet students’ needs and achieve learning objectives in the clinical skills education of Korean medicine colleges. Further studies are needed on ultrasound education, especially guided interventions for traditional medicine students.

Development of an Objective Structured Clinical Examination Checklist and a Post-Education Questionnaire for Musculoskeletal Ultrasound Training Focusing on Volar Wrist and Carpal Tunnel Syndrome

Background: The objective structured clinical examination (OSCE) is used in the colleges of Korean Medicine, but few studies have validated the OSCE evaluation criteria or post-education questionnaires. Diagnostic ultrasound is used in Korean medicine treatment including acupuncture, acupotomy, and pharmacopuncture to increase the safety and efficacy of treatment. We aimed to develop and validate a OSCE checklist and questionnaire for diagnostic musculoskeletal ultrasound training.Methods: A OSCE checklist and rubric for diagnostic ultrasound training, and questionnaire was developed using literature research. Eight expert panelists verified each draft item in a single-round survey. Items with a content validity ratio (CVR) < 0.75 were excluded or modified to reflect the experts’ opinions.Results: The OSCE checklist and rubric for diagnostic ultrasound training focusing on volar wrist and carpal tunnel syndrome included: 15 items revised according to CVR and expert opinions, the pre-examination procedure, structures to be identified by ultrasound, scans with 2 diagnostic criteria for carpal tunnel syndrome, an explanation of the exam results, and the post exam procedure. The questionnaire consisted of 15 items, including the overall evaluation of training, the effect of the OSCE, and the perception of the ultrasound. All 6 self-evaluation items were not revised, as they had a CVR of ≥ 0.75.Conclusion: An ultrasound OSCE for scanning the volar wrist and diagnosing carpal tunnel syndrome was developed using 15 validated tasks, 15 survey questions about ultrasound training, and 6 questions for selfevaluation. These results may be used in the future for education in diagnostic ultrasound.
