背景:清华大学材料学院"新型陶瓷与精细工艺"国家重点实验室研制出的远红外陶瓷微珠产品,应用陶瓷胶态注射成型工艺制造而成,是运动康复以及日常保健领域中的一种新型理疗材料,以其独特的颗粒细小圆形结构能够完整覆盖敷于脚部、腰部、大腿等损伤部位进行全面刺激干预。目的:探讨远红外陶瓷微珠对肌肉损伤后疼痛程度的影响。方法:选择18-21岁各体育专业符合股后肌群损伤诊断标准的在校学生30名,均对试验方案知情同意。随机分为3组,每组10名,按摩组进行按摩治疗,远红外仪组进行普通远红外治疗仪治疗,陶瓷微珠组进行远红外陶瓷微珠治疗,连续干预2周,治疗前与治疗后第3,7,14天测定McGill疼痛量表评分(包括疼痛分级指数、目测类比评分和现有疼痛程度),并进行组内、组间比较。结果与结论:①疼痛分级指数(感觉分、情绪分和总分)、目测类比评分和现有疼痛程度3组治疗前相比,差异无显著性意义(P>0.05),具有可比性;②陶瓷微珠组治疗3 d后各项疼痛评分均显著低于按摩组、远红外仪组(P<0.05);治疗7,14 d后,陶瓷微珠组各项指标均显著低于按摩组、远红外仪组(P<0.01);③陶瓷微珠组治疗3 d后,各项疼痛评分显著低于治疗前(P<0.05);与同时相其他2组相比也显著降低(P<0.05);④陶瓷微珠组治疗7 d后,各项疼痛评分显著低于治疗前(P<0.01);与同时相其他2组相比也显著降低(P<0.05);⑤治疗14 d后,按摩组、远红外仪组各项疼痛评分显著低于治疗前(P<0.05);而陶瓷微珠组各项疼痛评分也显著低于治疗前(P<0.01),与同时相其他2组相比也显著降低(P<0.01);⑥提示远红外陶瓷微珠可有效减轻股后肌群受伤肌肉的疼痛程度,有效促进肌肉损伤的恢复。

BACKGROUND: The far-infrared ceramic microspheres developed by the State Key Laboratory of "new ceramics and fine technology" of School of Materials, Tsinghua University, are made with ceramic colloidal injection molding technology. It is a new type of p hysical therapy material in the field of sports rehabilitation and daily health care. With its unique small circular structure, it can completely cover the damaged parts such as feet, waist, thigh, etc. to achieve comprehensive stimulation intervention. OBJECTIVE: To investigate the effect of far-infrared ceramic microspheres on pain intensity after muscle injury. METHODS: Thirty college students aged 18-21 years who met the diagnosis standard of posterior femoral muscle group injury were included in this study. All of them provided informed consent. They were randomly divided into three groups, with 10 students per group. Students in the massage group underwent massage therapy. Students in the far-infrared instrument group were treated with ordinary far-infrared therapeutic apparatus. Students in the far-infrared ceramic microsphere intervention group underwent far-infrared ceramic microsphere intervention. All treatments lasted 2 successive weeks. Before and 3, 7, and 14 days after treatment, McGill pain scale score(including pain rating index, visual analogue score and present pain intensity) was measured and compared within and between groups. RESULTS AND CONCLUSION:(1) Before treatment, there were no significant differences in pain rating index(sensory, affective, and total pain rating index scores), visual analogue score and present pain intensity between three groups(P > 0.05).(2) At 3 days of treatment, pain rating index, visual analogue score and present pain intensity score in the far-infrared ceramic microsphere intervention group were significantly lower compared with the massage and far-infrared instrument groups(P < 0.05). After 7 and 14 days of treatment, each studied indicator in the far-infrared ceramic microsphere intervention group was highly significantly lower compared with the other two groups(P < 0.01).(3) At 3 days of treatment, score of each pain indicator in the far-infrared ceramic microsphere intervention group was significantly lower compared with before treatment(P < 0.05), and it was significantly decreased compared with that measured concurrently in the other two groups(P < 0.05).(4) At 7 days of treatment, score of each pain indicator in the far-infrared ceramic microsphere intervention group was significantly lower compared with before treatment(P < 0.01), and it was significantly decreased compared with that measured concurrently in the other two groups(P < 0.05).(5) After 14 days of treatment, score of each pain indicator in the massage and far-infrared instrument groups was significantly lower compared with before treatment(P < 0.05). After 14 days of treatment, score of each pain indicator in the far-infrared ceramic microsphere intervention group was highly significantly lower compared with before treatment(P < 0.01). After 14 days of treatment, score of each pain indicator in the far-infrared ceramic microsphere intervention group was significantly lower compared with the other two groups. These findings suggest that far-infrared ceramic microsphere intervention can effectively reduce the degree of posterior femoral muscle group injury and effectively promote the recovery of muscle injury.
