林氏颈椎定点旋转斜扳法所致咔哒声时的推扳力研究

A study on thumb manipulative forces of cervical rotatory and local manipulation during cracking sounds

目的:测量林氏颈椎定点旋转斜扳法所致咔哒声时的推扳力的大小,为林氏手法的传承、教学、推广、基础研究提供量化依据。方法:使用多点薄膜压力测试系统,记录林氏颈椎定点旋转扳法及传统颈椎旋转手法操作中产生咔哒声时的拇指推扳力大小。结果:两种手法左旋时利手拇指推扳力和右旋时非利手拇指最大推扳力比较差异具有统计学意义(P<0.05)。同侧林氏颈椎定点旋转斜扳法所用的最大推扳力小于传统颈椎旋转手法,差异具有统计学意义(P<0.05)。结论:无论是传统颈椎旋转手法还是林氏颈椎定点旋转斜扳法利手拇指最大推扳力都大于非利手;两种手法比较提示,林氏颈椎定点旋转斜扳法更符合人体生物力学特点、更低耗能、更安全。

Objective To measure the thumb manipulative forces of Lin cervical rotation manipulation during cracking sounds, and provide quantitative basis for its inheritance, teaching and learning, promotion and basic research of the manipulation. Methods The thumb manipulative force of Lin cervical rotation manipulation and traditional cervical rotation manipulation during cracking sounds were tested and recorded with a multi-film pressure measurement system. Result There was statistically significant difference between the maximum thumb manipulative force of the hand used frequently and the hand used infrequently （P 〈 0.05）. The maximum thumb manipulative force of Lin cervical rotational manipulation is lower than the traditional cervical rotation manipulation （P 〈 0.05）. Conclusion Whether inIN traditional or Lin cervical rotation manipulation, the maximum thumb manipulative force of the hand used frequently is more than the hand used infrequently. Lin cervical rotation manipulation has better ergonomic characteristics of biological engineering, safer, more low energy consumption practices.
