【目的】 采集林氏挤压调整手法的动力学参数值，对其力学特性进行分析，以期制定相应合理的挤压调整手法的规范 化操作方案，指导该手法的临床教学。【方法】 选择10名年龄为20 ~ 30岁，在广东省中医院推拿科实习或进修的健康男性， 通过多点薄膜压力测试系统采集操作者在运用林氏挤压调整手法时的相关力学参数，对其力学特性进行分析，构建时间-力 学曲线数学模型。【结果】（1）林氏挤压调整手法预加载力平均值为（279.45 ± 19.36）N；持续时间平均值为（0.98 ± 0.03）s；谷 值平均值为（137.45 ± 3.59）N；最大冲击力平均值为（495.56 ± 7.33）N；冲击时间平均值为（0.15 ± 0.01）s；冲击速度平均 值为（3 183.96 ± 94.76）N/s；冲量平均值为（57.16 ± 1.82）N/s。（2）冲击力拟合函数上升和下降的斜率的绝对值都较大，且上升 的斜率远大于下降的斜率绝对值，说明林氏挤压调整手法的发力关键为快速短促的发力和收力。（3）单因素方差分析结果显 示，不同受试者的力学参数值预加载力、持续时间、谷值、按压最大冲击力和冲击时间比较，差异均无统计学意义（P＞ 0.05）。【结论】 不同受试者的力学参数值分析表明，林氏正骨推拿操作熟练者在进行挤压调整手法操作时，其力学参数维持 在一个相对稳定的水平；该研究从数字化角度初步分析了林氏正骨手法“骨错缝，筋出槽”的手法力作用特点，为林氏手 法的操作提供了客观的评价指标。

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 timemechanics 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.
