观察膝关节功能锻炼、膝关节功能锻炼结合肌内效贴对膝骨关节炎的治疗效果,选取患有膝骨关节炎的患者30例,随机分配:对照组15例,进行常规的膝关节功能锻炼;观察组15例,进行膝关节功能锻炼的同时,并给予贴扎治疗.实验周期为6周,分别在实验周期的前后各一天评估.使用疼痛视觉模拟评分量表(VAS)和Lequesne评分表来评估临床疗效.疗程结束后,观察组患者的VAS评分和Lequesne评分较对照组均有更明显的改善(P<0.05).得出结论如下:出现膝骨关节炎伤病后,进行膝关节功能锻炼和膝关节功能锻炼结合肌内效贴两种方法都有很好的治疗效果,但膝关节功能锻炼结合肌内效贴治疗对于改善KOA患者关节疼痛、僵硬以及日常活动障碍作用效果更加明显. 相似文献

目的主要运用生物力学的方法研究不同踝关节保护措施对足球运动员侧切时支撑腿力学特征的影响。方法运用红外光点运动捕捉系统同步三维测力台,对足球运动员在不采取踝关节保护措施、贴扎和佩带护具3种状态下侧切过程中支撑腿有关力学参数进行分析。结果在侧切过程中,贴扎缩短了受试者从接触地面到达首次垂直地面反作用力峰值的时间,减小了足最大背屈角度、最大内翻角度和最大内翻角速度;护具显著减小了足最大背屈角度,明显增加了最大内翻角度和踝关节最大外翻力矩。结论贴扎能有效地减小踝关节活动度,但使人体侧切着地初期缓冲能力下降;贴扎能为人体保护机制提供更多的时间来应对踝内翻,也许会减少踝关节潜在的损伤。护具能有效地限制了踝的屈伸活动度。二者的使用并未对膝关节带来消极影响。 相似文献

肌内效贴作为一种临床辅助治疗手段,在运动损伤后的止痛和消肿等方面具有良好的作用效果。近年来,人们在关注肌内效贴对运动损伤的预防和治疗的同时,也在探寻其在改善人体运动能力和提高运动表现等方面的作用效应。已有研究表明,肌内效贴对改善人体的静态平衡能力、本体感觉机能以及受损关节的活动范围是有效的,大多研究证据也支持肌内效贴对预防和改善运动性疲劳具有积极效应。而肌内效贴对健康人的关节活动范围和动态平衡能力的改善作用未得到证明,对肌内效贴是否能够改善人体肌肉力量和跳跃能力争议也较大。尽管有证据支持肌内效贴对人体某些运动能力有一定的促进作用,但仍存在矛盾性结论,其作用功效未得到医学和体育领域的广泛认可,所以有进一步的研究价值和应用前景。在后续的研究中,要综合性考虑因肌内效贴扎方式上不同而造成的作用效能间的差异;引入医学研究技术和方法,来探讨肌内效贴的作用功效和作用机理;研究对象要注意运动员群体的选择;研究的试验设计要更为科学,以确保方法学上的质量控制。 相似文献

为探索肌内效贴贴扎小腿腓肠肌对纵跳动力学特征及小腿其他肌肉活动的影响,本文对10名国家二级及以上水平运动员进行无、有贴扎纵跳实验,每组5人随机进行纵跳实验,重复3次,选择最佳测试成绩进行对比分析。结果表明,肌内效贴能够提高纵跳高度（P＜0.01）,增加最大蹬伸力和最大缓冲力（P＜0.05）,对蹬伸时间和最大蹬伸力梯度也有影响（P＜0.05）;同时,在蹬伸阶段,肌内效贴贴扎使双腿内侧腓肠肌积分肌电（iEMG）和均方根振幅（RMS）增加（P＜0.05）,使一侧胫骨前肌iEMG和RMS减少（P＜0.05）。但在缓冲阶段,对小腿各肌肉IEMG和RMS均无显著性差异（P＞0.05）。可见,肌内效贴使部分纵跳动力学特征发生改变,对小腿内侧腓肠肌肌肉活动也有促进作用。 相似文献

Although patellar taping has been shown to reduce pain in participants with patellofemoral pain syndrome, the mechanisms of pain reduction have not completely been established following its application. The purpose of this study was to evaluate EMG activity of vastus medialis and vastus lateralis following the application of patellar taping during a functional single leg squat. Both vastus medialis obliquus-vastus lateralis onset and vastus medialis obliquus/vastus lateralis amplitude of 18 participants with patellofemoral pain syndrome and 18 healthy participants as controls were measured using an EMG unit. This procedure was performed on the affected knee of participants with patellofemoral pain syndrome, before, during, and after patellar taping during unilateral squatting. The same procedure was also performed on the unaffected knees of both groups. The mean values of vastus medialis obliquus-vastus lateralis onset prior to taping (2.54 ms, s = 4.35) were decreased significantly following an immediate application of tape (-3.22 ms, s = 3.45) and after a prolonged period of taping (-6.00 ms, s = 3.40 s) (P < 0.05). There was also a significant difference between the mean values of vastus medialis obliquus-vastus lateralis onset among controls (-2.03 ms, s = 6.04) and participants with patellofemoral pain syndrome prior to taping (P < 0.05). However, there were no significant difference between the ranked values of vastus medialis obliquus/vastus lateralis amplitude of the affected and unaffected knees of participants with patellofemoral pain syndrome and controls during different conditions of taping (P > 0.05). Decreased values of vastus medialis obliquus-vastus lateralis onset may contribute to patellar realignment and explain the mechanism of pain reduction following patellar taping in participants with patellofemoral pain syndrome. 相似文献

AbstractLateral ankle sprains (LAS) are one of the most common musculoskeletal injuries and as a response, clinicians often use external ankle taping prophylactically to reduce the prevalence of injuries. External ankle taping techniques have been shown to significantly reduce passive ankle range of motion; however, there is limited research on the effects of external ankle taping on lower extremity kinematics or kinetics during sport specific tasks. Therefore, our objective was to compare the effects of external ankle taping on ankle, knee and hip kinematics and kinetics compared to no taping during an anticipated sidestep cutting task and a straight sprint task. We conducted a cross-over laboratory study with 16 healthy males. Three-dimensional kinematics and kinetics were collected with a motion capture system and in-ground force plate during 5 trials of a sprint and anticipated side-step cut with or without external ankle taping. Group means and associated 90% confidence intervals were plotted across 100 data points for each task, significance being identified when the confidence intervals did not overlap for three consecutive data points. No significant kinetic or kinematic differences were identified between conditions for the tasks. External ankle taping does not influence lower extremity biomechanics during a control cutting task. 相似文献

The latency of the peroneus longus may be a key factor in the prevention of lateral ankle sprains (LASs). In addition, ankle taping is often applied to help prevent LASs. The purpose of this study was to determine the effects of a previous LAS and ankle taping on the latency of the peroneus longus after an inversion perturbation. Twenty-six participants, including 13 participants with no previous history of a LAS and 13 participants with a history of a single LAS completed the testing. Ankle taping was applied in a closed basket weave technique on one of the two testing days. The latency of the peroneus longus was determined by the onset of muscle activity exceeding 10 SD from baseline activity, after initiation of the 25 degrees inversion perturbation. A significant main effect (p < 0.05) was present for the ankle support condition, with ankle taping causing a significant reduction in latency of the peroneus longus (65.04 +/- 10.81 to 57.70 +/- 9.39 ms). There was no difference (p > 0.05) in latency between the injury groups. Ankle taping, immediately after application, reduces the latency of the peroneus longus among participants with and without a history of a LAS. 相似文献

Ankle taping is commonly used to prevent ankle sprains. However, kinematic assessments investigating the biomechanical effects of ankle taping have provided inconclusive results. This study aimed to determine the effect of ankle taping on the external ankle joint moments during a drop landing on a tilted surface at 25°. Twenty-five participants performed landings on a tilted force platform that caused ankle inversion with and without ankle taping. Landing kinematics were captured using a motion capture system. External ankle inversion moment, the angular impulse due to the medio-lateral and vertical components of ground reaction force (GRF) and their moment arm lengths about the ankle joint were analysed. The foot plantar inclination relative to the ground was assessed. In the taping condition, the foot plantar inclination and ankle inversion angular impulse were reduced significantly compared to that of the control. The only component of the external inversion moment to change significantly in the taped condition was a shortened medio-lateral GRF moment arm length. It can be assumed that the ankle taping altered the foot plantar inclination relative to the ground, thereby shortening the moment arm of medio-lateral GRF that resulted in the reduced ankle inversion angular impulse. 相似文献

When the ankle is forced into inversion, the speed at which this movement occurs may affect the extent of injury. The purpose of this investigation was to develop a fulcrum device to mimic the mechanism of a lateral ankle sprain and to determine the reliability and validity of the temporal variables produced by this device. Additionally, this device was used to determine if a single previous lateral ankle sprain or ankle taping effected the time to maximum inversion and/or mean inversion speed. Twenty-six participants (13 with history of a single lateral ankle sprain and 13 with no history of injury) completed the testing. The participants completed testing on three separate days, performing 10 trials with the fulcrum per leg on each testing day, and tape was applied to both ankles on one testing day. No significant interactions or main effects were found for either previous injury or ankle taping, but good reliability was found for time to maximum inversion (ICC = .81) and mean inversion speed (ICC = .79). The findings suggest that although neither variable was influenced by the history of a single previous lateral ankle sprain or ankle taping, both variables demonstrated good reliability and construct validity, but not discriminative validity. 相似文献
