Abstract:
Objective The kinetic parameters of Lin's squeezing-pressing adjustment manipulation were collected for the analysis of its mechanical characteristics,thus to establish a standardized operating procedure to guide clinical teaching of this technique.Methods Ten healthy male trainees(aged 20-30 years)from the Tuina Department of Guangdong Provincial of Chinese Medicine were selected as the subjects.A multi-point thin-film pressure testing system was used to collect mechanical parameters during the operation of Lin's squeezing-pressing adjustment manipulation.The mechanical characteristics were analyzed,and then a mathematical model of time-mechanics curve was constructed.Results(1)The kinetic parameters of Lin's squeezing-pressing adjustment manipulation were as follows:preload force averaged(279.45±19.36)N with a duration of(0.98±0.03)s,the valley value of preload force averaged(137.45±3.59)N,the maximum impact force was(495.56±7.33)N,the impact duration averaged(0.15±0.01)s,the impact velocity averaged(3 183.96±94.76)N/s,and the impulse was(57.16±1.82)N/s.(2)The fitting function of impact force showed large absolute values for both ascending and descending slopes,and the ascending slope was significantly greater than the descending slope,indicating that the Lin's manipulation stressed on rapid outburst of the strength and withdrawal of the strength.(3)One-way ANOVA revealed no statistically significant differences in the preload force and its duration and valley value,the maximum impact force,and impact time among different operators(P＞0.05).Conclusion The analysis of kinetic parameters demonstrates that skilled operators maintain relatively stable mechanical parameters when performing Lin's squeezing-pressing adjustment manipulation.This study provides a preliminary digital analysis of the mechanical characteristics of Lin's bone-setting manipulation in addressing"bone misalignment and tendon displacement",which supplies objective evaluation criteria for the technique.
