[Objective]Esthesia and algesthia quantitative analyzers (PainVision®) are instruments that enables us to objectively assess the pain intensity. By applying an electrical current we can measure the intensity of pre-existing pain (pain equivalent current) and the minimum electrical stimulation that can be sensed by the patient (minimum perceptible current). In this study, we used PainVision®to evaluate the effectiveness of acupuncture treatment in patients with chronic pain and compared pain-related parameters with the Visual analogue scale (VAS).
[Methods]Twenty-three patients (4 males, 19 females;median age of 68) with chronic pain were studied. Pain degree was evaluated by the following equation;
Pain degree = 100 x (pain equivalent current -minimum perceptible current)/minimum perceptible current.
Pain degree was compared with VAS at pre-and post-acupuncture treatment.
[Results]VAS, pain degree and pain equivalent current by PainVision®decreased significantly after acupuncture treatment (p < 0.0001, p < 0.0001 and p < 0.01, respectively). Minimum perceptible current did not change significantly (p > 0.05). Pain degree and VAS had relatively high correlation coefficients at pre-and post-treatment (r = 0.52, p < 0.05 and 0.47, p < 0.05;respectively). Changes in VAS and pain degree agreed in 87%of the cases.
[Conclusions]PainVision®is a useful tool to assess pain intensity objectively, and parameters derived from it correlated well with VAS. In patients with chronic pain, acupuncture treatment can be evaluated by PainVision®.

[Objective]To evaluate the effects of acupuncture treatment for refractory urinary urgency and incontinence after radical prostatectomy.
[Methods]Three patients who had urinary urgency and/or urinary incontinence four months after radical prostatectomy received acupuncture at the BL33(Zhongliao) point. Acupuncture was performed once per week for four weeks. Symptoms were assessed by the International Prostate Symptom Score, IPSS QOL index for subjective evaluation and Frequency-Volume chart for objective evaluation.
[Results]After acupuncture treatment, urinary urgency and urge incontinence were improved, however stress urinary incontinence persisted. The scores for IPSS and IPSS QOL index were improved. Frequency-Volume charts showed that voided volume was increased and frequency of urination decreased after acupuncture treatment.
[Conclusions]Acupuncture at the BL33point might be a useful treatment option for urinary urgency and urge incontinence after radical prostatectomy.

Background: Complementary medicine and alternative medicine have been included in the curricula of many medical schools and colleges; however, teaching methods have not been standardized. We gave lectures and practical instruction on acupuncture and moxibustion medicine to medical students during their clinical clerkship in anesthesiology. We used a questionnaire to evaluate the usefulness of small-group teaching.
Methods: The subjects were 93 fifth-year medical students doing clinical clerkships in anesthesiology. The clinical clerkship consists of small-group learning with 2 or 3 students per group. After a lecture and practical instruction on acupuncture and moxibustion were given, students were asked to fill out a questionnaire about their interest in and basic knowledge of acupuncture and moxibustion and whether they would like to master the technique.
Results: All 93 students answered the questionnaire （response rate, 100%）. After the small-group teaching, students became more interested in acupuncture and moxibustion and learned that the costs of treatment were covered by health insurance. Most students were interested mastering acupuncture and moxibustion in the future.
Discussion: Our results suggest that lectures and practical instruction during clinical clerkship are useful for getting medical students interested in acupuncture and moxibustion medicine.

In 2021, the Clinical Practice Guidelines (CPG) for the Management of Chronic Pain was published, and included a section on acupuncture treatment for integrated medicine and chronic headaches. The purpose of this symposium was to discuss the current understanding of the evidence for acupuncture treatment for chronic pain and the expansion of guidelines. As a working group member of the CPG, Dr. Namba Toshimune introduced the process of including acupuncture in the CPG and discussed not only each field of specialty but also the outlook for developing unique CPG for acupuncture. Dr. Kubo presented the status of basic research on acupuncture treatment for pain in recent years, introduced about the effects of acupuncture stimulation on adenosine, orexin, and oxytocin in mice and rats, as well as the specific reactions of acupuncture points to acupuncture stimulation, and emphasized the importance of basic research to establish the effectiveness of acupuncture for chronic pain. Dr. Udo Yukihiro provided a detailed review of clinical research on acupuncture treatment for chronic pain, reporting on the current status of acupuncture treatment methods, stimulation sites, and stimulation methods. Minakawa described the current situation where systematic education for acupuncturists has not been sufficiently implemented and discussed their own acupuncture treatments for patients with chronic pain. We hope that the contents of this symposium will be helpful in clinical practice, research, and education.
