RESUMO
[Objectives]The purpose of this study is to clarify the effect of acupuncture sensation on the body sway during a one-legged stance.[Methods] The study participants were 16 healthy adults (mean age 21.8±1.6 years). The study design was a crossover method, wherein the same individuals participated in the acupuncture stimulation condition and the control condition at intervals of more than one week. Evaluation was performed before and after each intervention by holding a one-legged stance for 40 seconds on a force plate. A total of six items of body sway were measured, including: circumferential area, rectangular area, effective value area, total trajectory length, unit trajectory length, and unit area trajectory length. In addition, Visual analog scale (VAS) was used to evaluate the ease with which the lower leg was subjected to force during measurement. In the acupuncture stimulation condition, single acupuncture was performed on the lower limb muscle group of the measuring leg, and the VAS of the acupuncture sensation was evaluated at the time of stimulation and at the end of measurement. Stainless steel disposable acupuncture needles (length: 50 mm, diameter: 0.20 mm.) were used for stimulation. The stimulation sites were the ST32, ST37, BL37, BL57, and GB37 of the test leg, and acupuncture needles were inserted to the desired depth and removed when sensation was felt. The control condition was the supine position for five minutes. Comparisons were made between the pre- and post-acupuncture stimulation conditions and the pre- and post-control conditions(body sway, lower leg VAS, acupuncture sensation VAS). [Results] There was no significant difference between the two conditions in terms of body sway. However, the VAS of lower limb effort was significantly lower, from 78.0±14.9 mm to 63.1±17.0 mm before and after the intervention (p<0.05). On the other hand, in the control condition, there was no significant difference from 79.5±12.3 mm to 75.2±12.7 mm before and after rest. The VAS of acupuncture sensation was 50.4±14.3 mm during stimulation and 9.8±9.0 mm at the end of measurement, which was significantly lower (p<0.05). [Conclusion] Acupuncture sensation did not affect the body sway before and after acupuncture stimulation. However, the subjective sensation of weakness appeared, suggesting that acupuncture stimulation may cause a transient sensation of weakness.
RESUMO
[Objective] This study aimed to investigate the awareness and perceptions of cosmetic acupuncture among ordinary women.[Method] A questionnaire method was adopted, with a target population of 1,000 ordinary women living in Shizuoka prefecture, which is considered a suitable location for test marketing in Japan.Questionnaires were distributed through the Chambers of Commerce in the prefecture by age group, according to the population ratio, and responses were obtained. The items included (1) basic information; (2) presence and type of facial cosmetic concerns; (3) experience of acupuncture, awareness of cosmetic acupuncture, the medium through which they learned of it, perception of effects, and experience of cosmetic acupuncture; (4) effects and types of cosmetic acupuncture, presence or absence of adverse effects, current treatment status, desired treatment outcomes and reasons for seeking treatment, wishes from treatment clinics, and wishes from practitioners; and (5) 1 month's investment in beauty.[Result] The response rate was 56.2%, and 91.8% of the participants perceived that they had facial cosmetic concerns; 28.8% had experience with acupuncture, whereas 42.0% had knowledge regarding cosmetic acupuncture. Television (45.3%) was the primary source of information regarding this. The most prevalent perception of the effects of cosmetic acupuncture was lifting (44.8%), and 43.2% of the 521 participants inexperienced with cosmetic acupuncture consented to treatment. Participants mostly reported being somewhat interested in the procedure as their reason for wanting to receive treatment (45.3%). The most common reason for opting out of treatment was due to pain (52.6%). Of those who experienced cosmetic acupuncture, 60.0% said they experienced positive effects, and lifting (62.5%) is the most frequently perceived outcome, which matched the commonly held perception. However, among the participants, 45.0% reported negative effects, while 47.5% received the treatment two or more times in the past but did not continue. Participants mainly wanted clean treatment centers and skilled practitioners. The most common monthly investment in beauty was between 3,000 yen and 5,000 yen (28.5%).[Discussion/Conclusion] The results suggest that many women have cosmetic concerns regarding their faces and expect lifting from cosmetic acupuncture. The low treatment rate among women and their reasons for not seeking re-treatment were elucidated in this study, despite their degree of awareness. Further, the problems associated with the development of cosmetic acupuncture were clarified.
