Electromyography (EMG) measures muscle electricity. It depends on muscle contraction and central motor control. Muscles react very sensitive on external signals (e. g. bleeding), The resulting changes can be shown in EMG.
PATIENTS, METHODS: A first study included 51 children and young adults from Costa Rica. They underwent a clinical examination and EMG of the hip, knee and ankle joints. Resting muscle tone, maximal isometric contraction and three typical isotonic movements of the joints were measured. First step of analysis was to characterize typical pathogenic changes in the muscles and to find a corresponding physical therapy to minimize these changes.
It showed that EMG is a good marker for muscle condition. It helps to individualize therapy and improve effectivity of physical and physiotherapeutic treatment of the locomotive system of children and young adults with hemophilia. It can help to recognize early subclinical changes and to control the outcome of therapeutic modalities.
肌电图（EMG）测量肌肉电活动。它取决于肌肉收缩和中枢运动控制。肌肉对外界信号（如出血）反应非常敏感，由此产生的变化可在肌电图中显示出来。
患者、方法：第一项研究纳入了51名来自哥斯达黎加的儿童和年轻人。他们接受了髋关节、膝关节和踝关节的临床检查及肌电图检查。测量了静息肌张力、最大等长收缩以及关节的三种典型等张运动。分析的第一步是确定肌肉中典型的致病变化，并找到相应的物理治疗方法以尽量减少这些变化。
结果表明，肌电图是肌肉状况的良好指标。它有助于使治疗个体化，并提高对血友病儿童和年轻人运动系统进行物理和物理治疗的有效性。它有助于识别早期亚临床变化并控制治疗方式的效果。
