To observe the features of acupuncture needle twirling manipulations in order to promote the development of objective and quantitative performance standards of acupuncture manipulation. Twelve expert acupuncturists and 12 novices were enrolled in this study. Everyone of them was instructed to perform 10 trials of the uniform reinforcing and reducing technique of acupuncture on an artificial skin-pad that was mounted to a six-axis force transducer and each subject had his or her dominant hand index finger affixed with an infrared light emitting diode for acquiring parameters of acupuncture needle manipulation. The force transducer was used to measure the force the participant applied as they held an acupuncture needle to stimulate the skin-pad, and at the mean time, an optoelectric camera was employed to measure the position of the diode. In comparison with the expert acupuncturist group, the straggling coefficient of needle-twirling frequency was significantly bigger in the novice group (P < 0.01), suggesting a higher consistency in the trial-by-trial needle-twirling operation of the expert acupuncturists. Comparison of the needle-twirling force showed that the force values of the Z-axis in both expert group and novice group were considerably higher than those of the X-axis and Y-axis in the same one group (P < 0.01). The time of pre-needle-twirling of the novice group was markedly longer than that of the expert group (P < 0.01), suggesting a skilled operation technique of the expert acupuncturists. No significant differences were found between the expert acupuncturist group and novice group in the needle-twirling amplitude, frequency, force and total operation time (P > 0.05). Movement frequency consistency and temporal efficiency are the action features of expert acupuncturists in performing the uniform reducing-reinforcing twirling skill, which differentiates the performances of experts from novices. The assessment and training of this acupuncture skill should focus on these kinematic features. Source

Acupuncture manipulation skills are the core of acupuncture therapy. Traditional acupuncture skills evaluation is based on experts' subjective assessment which is deficient in reliability and validity. Certain progresses on the quantitative research on acupuncture skills have been made in China, while there is still a long way to go before the formation of the consummate standardization evaluation system on acupuncture skills. Actually, quantitative appraisal on surgical skills has been developed for a long time in Europe and North America. Since acupuncture could be considered as a kind of skills of minimally invasive surgery because small wounds would be generated by needles, the theories and methods in surgical quantitative appraisal could be utilized. For instance, scales could be designed to evaluate the operation modes in acupuncture skills and precise instruments could be used in the measurement of acupuncture skills. Then standard databases on common acupuncture manipulations would be built. Moreover, in terms of the characteristics of acupuncture skills, high-fidelity simulators should be designed or standardized patients should be trained for the assessment of "Deqi" (arrival of qi)feelings. Thereby, an appropriate standardization evaluation system for acupuncture skills would be created gradually. Source

To observe the effect of clinical acupuncture practice on practitioners finger fine touch, so as to analyze the perceptive procedure of the arrival of qi and to explore its key factors. Fifteen healthy acupuncturists and 15 healthy non-acupuncturists volunteers were recruited in the present study. All the participants were ordered to take a sitting position in a quiet room and to have their eyes covered with two eyeshades first. Then, they were asked to receive two general sensory-perceptual acuity tests: the von Frey hair tests for measuring their cutaneous sensation threshold and two-point discrimination tests of the thumb, index and middle fingers of both hands. In acupuncturists, the average cutaneous sensation thresholds of the thumb and index finger of the handedness and the average two-point discrimination thresholds of the thumb, index finger and the middle finger of the handedness were lower than those of the handedness in non-acupuncturists in spite of no significant differences (P > 0.05). In addition, in acupuncturists, the average cutaneous sensation thresholds of the thumb and index finger and the average two-point discrimination thresholds of the thumb, index finger and the middle finger of the handedness were also slightly lower than those of their non-handedness. While in the non-acupuncturists, both the average cutaneous sensation thresholds and the average two-point discrimination thresholds of the thumb, index finger and the middle finger of the handedness and non-handedness were comparable. The acupuncturists' finger fine touch of the handedness is relatively more sensitive than that of non-acupuncturists, suggesting an increase of the sensitivity of fingers in perceiving "Deqi" through long-term acupuncture clinical practice.

Background: Children's health and health behaviour are essential for their development and it is important to obtain abundant and accurate information to understand young people's health and health behaviour. The Health Behaviour in School-aged Children (HBSC) study is among the first large-scale international surveys on adolescent health through self-report questionnaires. So far, more than 40 countries in Europe and North America have been involved in the HBSC study. The purpose of this study is to assess the test-retest reliability of selected items in the Chinese version of the HBSC survey questionnaire in a sample of adolescents in Beijing, China. Methods: A sample of 95 male and female students aged 11 or 15 years old participated in a test and retest with a three weeks interval. Student Identity numbers of respondents were utilized to permit matching of test-retest questionnaires. 23 items concerning physical activity, sedentary behaviour, sleep and substance use were evaluated by using the percentage of response shifts and the single measure Intraclass Correlation Coefficients (ICC) with 95% confidence interval (CI) for all respondents and stratified by gender and age. Items on substance use were only evaluated for school children aged 15 years old. Results: The percentage of no response shift between test and retest varied from 32% for the item on computer use at weekends to 92% for the three items on smoking. Of all the 23 items evaluated, 6 items (26%) showed a moderate reliability, 12 items (52%) displayed a substantial reliability and 4 items (17%) indicated almost perfect reliability. No gender and age group difference of the test-retest reliability was found except for a few items on sedentary behaviour. Conclusions: The overall findings of this study suggest that most selected indicators in the HBSC survey questionnaire have satisfactory test-retest reliability for the students in Beijing. Further test-retest studies in a large and diverse sample, as well as validity studies, should be considered for the future Chinese HBSC study. © 2010 Liu et al; licensee BioMed Central Ltd. Source

China puts more and more attentions to social public sports facility construction, studying on China social public sports facility utilization status has important significances in guiding national sports investment. The paper analyzes China social public sports facility utilization status by literature searching method and data statistical analysis method, it discovers Chinese sports facility cannot meet people demands, and has imbalanced utilization ratio status. To balance the status, the paper utilizes analytic hierarchy process, establishes factor analysis model, and by virtue of MATLAB software, it analyzes consideration factors that people select sports facilities, and gets each kind of influence factors weight. It is clear that factors of people mainly consideration are whether facility has fitness efficiency, equipment is complete or not, and whether it has losing weight efficiency. According to consideration factors, it makes suggestions on country as following: remove lower utilization ratio sports facilities to densely populated housing estates, parks; lay particular stress on housing estates’ old people sports facilities and district level national fitness activity center construction; focus on old sports facilities maintenance. © Jianguo Zhu; Licensee Bentham Open.
