摘　　要：背景:目前对侧卧定点踩跷法的研究较少,缺少对手法力学特征的分析,亦无关于快扳法及缓扳法的相关研究。目的:利用数字化方式分析不同扳动方式下侧卧定点踩跷法的各项力学参数异同。方法:选择2020年6月在广东省中医院大德路总院推拿科就诊的腰椎间盘突出症患者40例,随机分为2组,分别进行快扳方式下的侧卧定点踩跷治疗与缓扳方式下的侧卧定点踩跷治疗,每组20例,通过多点薄膜压力测试系统采集操作者在两种扳动方式下运用侧卧定点踩跷法时的手法轨迹图及相关力学参数。评估治疗前后患者的目测类比评分。结果与结论:(1)两种扳动方式均存在预加载相、助跑相及冲击相,快扳组预加载力、谷值、峰值、扳动速度及冲量均大于缓扳组(P<0.05),两组间加载时间、冲击时间比较差异无显著性意义(P>0.05);(2)两组治疗后的目测类比评分均低于治疗前(P<0.05),快扳组治疗后的目测类比评分低于缓扳组(P<0.05);(3)Pearson及Spearman相关性分析显示,治疗前后的目测类比评分差值与预加载力、峰值(即冲击力)的大小存在显著相关性(r=0.536,P<0.001;r=0.740,P<0.001);(4)结果显示,两种扳动方式下侧卧定点踩跷法单次治疗后腰椎间盘突出症患者的腰痛症状均得到明显改善,其中以快扳方式下的镇痛效果更佳;治疗前后的目测类比评分差值与预加载力及峰值大小存在显著相关性。BACKGROUND:There is a lack of analysis on the mechanical chara cteristics of the stepping lumbus of fixed-point at late ral decubitus position,and there is no relevant research on the fast-pushing method and the slow-pushing method.OBJECTIVE:To conduct a digital analysis on the simila rities and differences of various mechanical parameters of the stepping lumbus of fixed-point at lateral decubitus position under different pushing methods.METHODS:A total of 40 patients with lumbar intervertebral disc herniation who were treated in the Department of Massage of Dade Road General Hos pital of Guangdong Provincial Hospital of Chinese Medicine in June 2020 were selected and randomly divided into fast-pushing and slow-pushing groups(n-20).The manual trajecto ry and related mechanical paramete rs of the operator using the stepping lumbus of fixed-point at lateral decubitus position under two pushing modes were collected and compared thro ugh the multi-point membrane pressure test system.The visual analogue scale scores of the two groups were analyzed befo re and after treatment.RESULTS AND CONCLUSION:(1)There were preload force,run-up phase and impact phase in both pushing methods.Preload force,valley value,peak value,pushing speed,and impulse were larger in the fast-pushing group than those in the slow-pushing group(P<0.05).Duration and impact time were not significantly different between the two groups(P>0.05).(2)The visual analogue scale scores of the two groups were lower after treatment than those before treatment(P<0.05).Above score was lower in the fast-pushing group than that in the slow-pushing group(P<0.05).(3)Pearson and Spearman correlation analysis showed that there was a significant correlation between the visual analogue score difference before and after treatment,and the magnitude of preload force and peak value(i.e.impact fo rce)(r=0.536,P<0.001;r=0.740,P<0.001).(4)The low back pain symptoms of patients with lumbar intervertebral disc herniation were significantly improved after a single treatment of the
