摘要
目的:探讨健康人肩胛部潜在扳机点对肌力的影响。方法:将优势侧肩胛部存在潜在扳机点的27例健康志愿者纳入观察组,将双侧肩胛部均不存在潜在扳机点的23例健康志愿者纳入对照组。测定受检者双侧肩胛部前屈肌力和外展肌力。结果:2组受检者优势侧和非优势侧肩胛部前屈肌力及外展肌力比较,差异均无统计学意义[(14.75±5.10)kg·cm-2,(14.35±4.70)kg·cm-2,t=0.688,P=0.344;(17.82±4.90)kg·cm-2,(17.43±4.40)kg·cm-2,t=0.642,P=0.254;(15.13±5.10)kg·cm-2,(14.97±4.90)kg·cm-2,t=0.671,P=0.552;(18.45±4.40)kg·cm-2,(18.11±4.70)kg·cm-2,t=0.691,P=0.350];对照组优势侧和非优势侧肩胛部前屈肌力及外展肌力均大于观察组(t=2.125,P=0.037;t=2.369,P=0.021;t=2.417,P=0.019;t=2.178,P=0.026)。结论:存在潜在扳机点的受检者,其优势侧和非优势侧的肩胛部肌力无明显差别,但均低于不存在潜在扳机点的受检者。
Objective：To explore the effect of potential trigger points（PTP） in scapular region on scapular muscle strength in healthy people.Methods：Twenty-seven healthy volunteers with PTP in their dominant side scapular region were recruited into observation group,while 23 healthy volunteers without PTP in both of their scapular region were recruited into control group.Forward bending muscle strength and abduction muscle strength were measured in both of the scapular region of volunteers.Results：There were no statistical differences in forward bending muscle strength and abduction muscle strength between dominant and none-dominant side scapular in the 2 groups （14.75 ＋/-5.10 vs 14.35 ＋/-4.70 kg/cm（2）,t =0.688,P =0.344;17.82 ＋/-4.90 vs 17.43 ＋/-4.40 kg/cm（2）,t =0.642,P =0.254; 15.13 ＋/-5.10 vs 14.97 ＋/-4.90 kg/cm（2）,t =0.671,P =0.552;18.45 ＋/-4.40 vs 18.11 ＋/-4.70 kg/cm（2）,t =0.691,P =0.350）,while the forward bending muscle strength and abduction muscle strength in both scapular of control group were all greater than those of observation group （t =2.125,P =0.037 ; t =2.369,P =0.021 ; t =2.417,P =0.019 ; t =2.178,P =0.026）.Conclusion：There is no significant difference in scapular muscle strength between both scapular in the subjects with PTP,however,the scapular muscle strength of subjects with PTP is lower than that of subjects without PTP.
