[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.

[Aim] We compared the effects of acupuncture and press tuck needle (PTN) acupuncture in office workers with physical and psychological fatigue.[Design] A randomized, open-label, parallel-group, comparison study.[Setting] An acupuncture room in the A Clinic within the Kanto Metropolitan Area.[Patients] Clinic workers. The inclusion criteria were 20-45 years of age and awareness of physical and psychological fatigue. The exclusion criteria were fatigue-related diseases and symptoms, medical abnormalities, and history.[Intervention] The subjects were randomly allocated to either the acupuncture treatment group (ACP group) or PTN acupuncture treatment group (PTN group). The interventions were based on acupoints for fatigue symptoms as per previous reports and individualized treatment for physical symptoms, including neck and lower back pain, among others, and were performed twice a week for one month.[Evaluation methods] The visual analog scale (VAS) scores were the primary method for evaluating for physical and psychological fatigue at four weeks post-treatment. Other forms of measurement used were the VAS scores within groups immediately after treatment and to evaluate physical health, the Health Perceptions Questionnaire, General Health Questionnaire-12, and Short Form-36 responses; and salivary amylase levels were used.[Results] Thirteen of 14 subjects in the ACP group and 13 of 15 in the PTN group were included in the analysis. There was no significant difference between the groups for VAS scores. Evaluation, immediately before and after the intervention showed a significant decrease in VAS scores for physical fatigue in both groups. The ACP group showed a greater immediate change than the PTN group. In a comparison within each group, the VAS of psychological fatigue in the PTN group showed significant decrease after the eighth treatment.[Conclusions] Acupuncture may immediately improve physical fatigue in office workers. Moreover, the frequency of using PTN acupuncture may eventually decrease physical fatigue. Therefore, acupuncture and PTN acupuncture can help office workers' health.

Objective: Neck pain is a very common complaint in the general population. However, little is known about the characteristics of this complaint. The aim of this study was to clarify the psychological and physical characteristics of neck pain. Method: The subjects were 13 adult men with complaints of neck pain (NP group, mean age 20.2±0.7 years) and 10 healthy volunteers (CON group, mean age 21.2±1.5 years). This study used findings of neck tenderness and muscle stiffness for evaluation of neck pain, and employed the visual analog scale (VAS) to record the subjects’ assessment of their pain. State-Trait Anxiety Inventory (STAI), MOS 36-Item Short-Form Health Survey (SF-36), VAS for evaluation of perceived stress, and measurements of salivary cortisol density levels were utilized to measure stress. The salivary cortisol density was measured by the enzyme immunity method of measurement (the ELISA method). In addition, saliva samples were collected between 9 AM to 10 AM. Results: The mean VAS score for neck pain in the NP group was 56.9±17.3. There was no significant difference in muscle stiffness between the groups. Tenderness of the upper trapezius fibers and right splenius capitis muscle were significantly higher in the NP group (p<0.05). The VAS score of perceived stress and the state anxiety of STAI were significantly higher in the NP group (p<0.05). The SF-36 score was significantly lower in the CON group (p<0.05). The trait anxiety of STAI and the salivary cortisol density were not significantly different. Conclusion: There was no significant difference in the salivary cortisol density levels between the two groups. The degrees of perceived stress and uneasiness were reported as higher in the NP group, while the degrees of psychological and physical health were lower. These findings suggest the role of psychosociological factors in neck pain.

 Forty-one patients with periarthritis with no evident articular contracture at the start of acupuncture (at the first presentation) were divided into 13 subjects who developed articular contracture during acupuncture (transition group) and 28 subjects who did not (non-transition group), and the clinical characteristics of the two groups were compared.  The following results were obtained. (1) The mean age of the subjects was significantly higher in the transition group than in the non-transition group (58.5±6.8 years vs. 52.1±9.6 years). (2) The percentage of subjects in the transition group was significantly higher in the subjects not clearly diagnosed as having no contracture at the first presentation than clearly diagnosed as no contracture (57% vs. 19%). (3) The percentage of subjects in the transition group was significantly higher in the subjects in whom the lesion site was enlarged or could not be identified than independent (50% vs. 17%). (4) The percentage of subjects in the transition group was significantly higher in the subjects with nocturnal pain than without (64% vs. 15%). (5) The transition group was unlikely to show improvement of pain or restriction of the range of motion with acupuncture as compared to the non-transition group.  The possibility of developing articular contracture should be considered while providing treatment by acupuncture and guidance to patients showing the above tendencies.
