摘要
背景:研究表明,桡侧腕屈肌和尺侧腕屈肌弹性的大小与手握力的大小相关,其张力和刚度直接影响着拇指侧捏力和掌心抓握的能力。体外冲击波对于缓解脑卒中后肢体痉挛有明确的疗效。目的:观察体外冲击波对脑卒中患者桡侧腕屈肌和尺侧腕屈肌的肌肉张力、刚度及弹性的即刻影响。方法:选取20例符合入选标准的脑卒中偏瘫患者,对其桡侧腕屈肌和尺侧腕屈肌进行单次体外冲击波治疗。在治疗前及单次体外冲击波治疗结束后5 min,应用Myonton-3肌肉张力检测仪测得患侧桡侧腕屈肌及尺侧腕屈肌的阻尼振动频率(体现肌肉张力)、对数衰减值(反映肌肉弹性)、动态刚度(体现肌肉刚度),同时结合改良Tardieu量表(MTS)评估腕屈肌肌张力。研究方案的实施符合广东药科大学附属第一医院的相关伦理要求,参与试验的患病个体及其家属对试验过程完全知情同意。结果与结论:①干预后,20例患者桡侧腕屈肌及尺侧腕屈肌的阻尼振动频率、对数衰减值、动态刚度、肌肉反应的质量均较治疗前下降(P<0.01);②患侧腕关节被动背伸角度、最快速度下的腕背伸卡住角度均较治疗前增加(P<0.01);③结果说明,单次体外冲击波能有效降低脑卒中患者桡侧腕屈肌和尺侧腕屈肌的肌张力及刚度,改善其弹性,并可增大腕背伸被动活动范围。
BACKGROUND:Studies have shown that the elasticity of the radial wrist flexor and ulnar wrist flexor muscles is related to the power of gripping,and the tension and stiffness directly affect the pinching force on the thumb side and the palm gripping ability.Extracorporeal shock waves have a definite effect on alleviating post-stroke limb spasm.OBJECTIVE:To observe the immediate effect of extracorporeal shock wave therapy on muscle tone,stiffness,and elasticity of flexor carpi radialis and flexor carpi ulnaris in stroke patients.METHODS:Twenty stroke patients with hemiplegia who met the inclusion criteria were given a single session of extracorporeal shock wave therapy on flexor carpi radialis and flexor carpi ulnaris.The oscillation frequency,logarithmic decrement,dynamic stiffness of flexor carpi radialis and flexor carpi ulnaris were detected using a muscle tone measurement device Myoton-3 before treatment and 5 minutes after treatment.At the same time,the Modified Tardieu Scale was used to evaluate spasticity of wrist flexor before and after treatment.The study protocol was implemented in accordance with the relevant ethical requirements of the First Affiliated Hospital of Guangdong Pharmaceutical University,and the enrolled patients and their families were fully informed of the whole trial.RESULTS AND CONCLUSION:After treatment,the oscillation frequency,logarithmic decrement,dynamic stiffness,and quality of muscle response of flexor carpi radialis and flexor carpi ulnaris were significantly reduced in all the patients(P<0.01).The maximum passive range of motion of wrist extension and angle of catch following a fast velocity stretch wrist flexor were significantly higher than those before(P<0.01).In conclusion,a single session of extracorporeal shock wave therapy can effectively reduce muscle tone and stiffness,and improve elasticity of flexor carpi radialis and flexor carpi ulnaris in stroke patients.And it can also improve the maximum passive range of motion of wrist extension.
