Changes in three physical indicators of the muscle after far-infrared ceramic microsphere intervention

背景:远红外光波治疗可促进血液快速流动、强化各组织间物质能量交换和促进骨骼肌微损伤快速恢复等能力,其中远红外陶瓷微珠为近年来运动理疗、康复领域一种崭新的功能康复材料。目的:以远红外陶瓷微珠为干预手段,验证其对骨骼肌损伤后肌肉伸展性、肌肉硬度和肌肉弹性物理3特性指标的影响。方法:选择年龄18-21岁各体育专业确诊为股后肌群损伤的男性在校学生为试验对象,通过筛选最终纳入20名受试者,随机数字表法分为2组,分别进行普通远红外治疗仪(对照组)与远红外陶瓷微珠干预治疗(试验组),每组10名受试者,连续干预2周。利用无创肌肉检测系统采集治疗前与治疗后第3,7,14天的股后肌肉伸展性、肌肉硬度和肌肉弹性数据。结果与结论:①试验组治疗后3,7,14 d的肌肉伸展性大于治疗前(P<0.05,P<0.01),且治疗后14 d已恢复至健侧水平(P>0.05);对照组仅治疗后14d的肌肉伸展性大于治疗前(P<0.05),但仍低于健侧(P<0.05);试验组治疗后不同时间点的肌肉伸展性大于对照组(P<0.05,P<0.01);②试验组治疗后3,7,14 d的肌肉硬度大于治疗前(P<0.05,P<0.01),且治疗后14 d已恢复至健侧水平(P>0.05);对照组仅治疗后14 d的肌肉硬度大于治疗前(P<0.05),但仍低于健侧(P<0.05);试验组治疗后不同时间点的肌肉硬度大于对照组(P<0.05,P<0.01);③试验组治疗后3,7,14 d的肌肉弹性大于治疗前(P<0.05,P<0.01),且治疗后14 d已恢复至健侧水平(P>0.05);对照组仅治疗后14 d的肌肉弹性大于治疗前(P<0.05),但仍低于健侧(P<0.05);试验组治疗后不同时间点的肌肉弹性大于对照组(P<0.05,P<0.01);④结果表明,远红外陶瓷微珠干预可提高肌肉的伸展性、弹性,降低肌肉硬度,促进损伤肌肉的恢复。

BACKGROUND:Far-infrared wave therapy can accelerate blood flow rapidly,strengthen the exchange of substance and energy among tissues,and promote the rapid recovery of musculoskeletal micro-injury.The far-infrared ceramic microsphere is a new functional rehabilitation material in the field of physical therapy and rehabilitation in recent years.OBJECTIVE:To verify the therapeutic effectiveness of far-infrared ceramic microsphere intervention on muscle extensibility,stiffness,and elasticity after musculoskeletal injury.METHODS:Male students aged 18-21 years who were diagnosed with posterior femoral muscle injury in each sports specialty were selected as test subjects.Twenty subjects were selected and randomly divided into two groups(n=10/group),and then underwent far-infrared therapeutic apparatus(control group)and far-infrared ceramic microsphere intervention treatment(trial group)for 2 consecutive weeks.A non-invasive muscle detection system was used to collect muscle extensibility,muscle stiffness,and muscle elasticity data before and 3,7,and 14 days after treatment.RESULTS AND CONCLUSION:(1)The muscle extensibility in the trial group at 3,7,and 14 days after treatment was higher than that before treatment(P<0.05,P<0.01),and it had returned to the level of the healthy side at 14 days after treatment(P>0.05).In the control group,the muscle extensibility at 14 days after treatment was higher than that before treatment(P<0.05),but it was still lower than that of the healthy side(P<0.05).The muscle extensibility at different time points in the trial group was higher than that in the control group(P<0.05,P<0.01).(2)The muscle stiffness in the trial group at 3,7,and 14 days after treatment was higher than that before treatment(P<0.05,P<0.01),and at 14 days after treatment,it had returned to the level of the healthy side(P>0.05).In the control group,the muscle stiffness at 14 days after treatment was higher than that before treatment(P<0.05),but it was still lower than that of the healthy side(P<0.05).The muscle stiffness at different time points in the trial group was higher than that in the control group(P<0.05,P<0.01).(3)The muscle elasticity in the trial group at 3,7,and 14 days after treatment was higher than that before treatment(P<0.05,P<0.01),and at 14 days after treatment it had returned to the level of the healthy side(P>0.05).In the control group,the muscle elasticity at 14 days after treatment was higher than that before treatment(P<0.05),but it was still lower than that of the healthy side(P<0.05).The muscle elasticity at different time points in the trial group was higher than that in the control group(P<0.05,P<0.01).(4)In summary,far-infrared ceramic microspheres can improve muscle extensibility and elasticity,reduce muscle stiffness and promote the recovery of muscle damage.
