旋提手法智能教学机器人系统在颈椎手法教学中的应用

Application of intelligent robot system in teaching cervical spine manipulation

目的探讨旋提手法智能教学机器人系统在颈椎手法教学中的应用效果。方法将60名初学颈椎旋提手法的医师随机分为对照组(n=30)和试验组(n=30)。对照组通过一名具有合格证的主任医师采用"PPT讲解+视频播放+操作演示"教学,各部分均为5 min;试验组通过旋提手法智能教学机器人系统教学,两组教学时间均为15 min。2次教学结束后,2组在不同体质量指数(BMI)下通过该系统训练5次后进行考核。比较2组在不同BMI下的预牵引力、提扳力、最大作用力、预牵引时间、提扳时间、旋转幅度和俯仰幅度的合格率。结果在正常人群中,2组的预牵引力、提扳力、最大作用力、预牵引时间、提扳时间、旋转幅度和俯仰幅度的合格率比较差异均有统计学意义(均P<0.05);在超重人群中,2组的预牵引力、提扳力、最大作用力及旋转幅度的合格率比较差异均有统计学意义(均P<0.05),预牵引时间、提扳时间及俯仰幅度的合格率比较差异均无统计学意义(均P>0.05);在肥胖人群中,2组的预牵引力、提扳力、最大作用力及俯仰幅度的合格率比较差异均有统计学意义(均P<0.05),预牵引时间、提扳时间及旋转幅度的合格率比较差异均无统计学意义(均P>0.05)。结论旋提手法智能教学机器人系统能够提高初学医师旋提手法操作的合格率,尤其能够有效地掌控预牵引力、提扳力及最大作用力。

Objective To explore the application effect of an intelligent teaching robot system of lifting manipulation in cervical spine manipulation teaching.Methods 60 doctors were randomly divided into an experimental group(n=30)and a control group(n=30).The control group was taught by a certified chief physician using a combination of"PowerPoint presentations,video demonstrations,and operation demonstrations".Each part is 5 min.The experimental group was taught by the intelligent teaching robot system with a spinning technique.The teaching time is 15 min for both groups.At the end of the two teaching sessions,the two groups were trained five times under different BMIs and passed the system assessment.The qualified rates of pre-traction force,lifting and pulling force,maximum force,pre-traction time,lifting and pulling time,rotation amplitude,and pitch amplitude were compared between the two groups.Results In normal,there was significant differences between the qualified rates of pre-traction force,lifting and pulling force,maximum force,pre-traction time,lifting and pulling time,rotation amplitude,and pitch amplitude in two groups(all P<0.05).For overweight people,there were significant differences in pre-traction force,pulling force,maximum force,and rotation amplitude(all P<0.05),while there were no significant differences in pre-traction time,pulling time,or pitching amplitude(all P>0.05).In obesity,there were significant differences in pre-traction force,lifting and pulling force,maximum force,and pitch amplitude(all P<0.05),but no significant differences in pre-traction time,lifting and pulling time,or rotation amplitude(all P>0.05).Conclusions The proposed system can improve the pass rate of spinning manipulation,especially by effectively controlling the pre-traction force,pulling force,and maximum force.
