ABSTRACT
OBJECTIVE@#To conduct a pilot trial to explore the effectiveness and safety of moxibustion robots in treating primary dysmenorrhea (PD) and evaluate its feasibility in clinic.@*METHODS@#A total of 70 participants with PD were allocated to either moxibustion robot (MR) group (35 cases) or manual moxibustion (MM) group (35 cases) using computer-generated randomization. One acupoint Guanyuan (CV 4) was selected to receive moxa heat stimulation. Two groups of participants were given 3 menstrual cycles of MM and MR treatment respectively (once a day, 5 days a session) and received another 3 menstrual cycles follow-up. The degree of pain was evaluated by short-form McGill pain questionnaire (SF-MPQ) and the symptoms of dysmenorrhea were evaluated by Cox Menstrual Symptom Scale (CMSS). The safety was measured by the occurrence rate of adverse events (AEs), including burns (blisters, red and swollen), itching, bowel changes, menstrual cycle disorder, menorrhagia and fatigue, etc. RESULTS: A total of 62 patients completed the trial, 32 in MR group and 30 in MM group. Compared with baseline, scores of SF-MPQ and CMSS significantly decreased in both groups (P0.05). The total occurrence rate of AEs in MR group was 2.1%, which was significantly lower than MM group (7.2%, P<0.05).@*CONCLUSIONS@#MR has the same effect as MM at SF-MPQ and CMSS in patients with PD. However, MR is safer than MM (Trial registration No. ChiCTR1800018236).
ABSTRACT
In view of the limitations of the existing moxibustion instruments, i.e. possible accidental injury when using moxibustion instruments, the negative effects of products from moxibustion instruments on treatment efficacy and health of medical staff and patients, a moxibustion instrument with multi-jointed manipulator is designed. This moxibustion instrument could accurately control the temperature, maintain a safe moxibustion distance, automatically process the burning ashes of moxa and selectively handle moxa smoke. The experimental results shows that this instrument could maintain the constant temperature of target acupoint, reduce the risk of empyrosis, and reasonably deal with the products of moxibustion. The purification rate of moxa smoke is 44.9%, which not only ensures the therapeutic effect of moxa smoke, but also reduces the negative effects of high-concentration moxa smoke on the health of medical staff and patients.

Traditional moxibustion treatment mainly relies on doctors using specific techniques to stimulate the patient's acupoints with ignited moxa sticks. In view of the poor reproducibility, and different methods of different doctors, difficult to carry out quantitative and qualitative research work in clinical research, a moxibustion mechanical arm was designed. The hardware modules of the mechanical arm are composed of power, micro controller STM32, position servos, moxibustion strip thruster, human-computer interaction panel and sensors; the software parts are composed of main control program and interrupt service program. The use of this moxibustion mechanical arm will enhance the system's multi-task adaptability and could perform a variety of moxibustion methods including circling moxibustion and sparrow-pecking moxibustion. The data collected in real time will be transmitted to PC through bluetooth, displayed on OLED, and the system operation modes could be switched by button. Clinical trials showed that moxibustion mechanical arm had the same treatment effects with traditional moxibustion. Meanwhile, its convenience of ope-ration, repeatability of treatment, doctors and patients's treatment experience are all better than those of traditional moxibustion.
