[Purpose] This study investigated changes in the activation of the main elbow muscle while performing tasks similar to activities of daily living (ADL) with and without a cock-up splint. [Methods] Sixteen participants performed a simulated feeding task and picked up light and heavy cans in the Jebsen-Taylor hand function test. The activation of the biceps brachii, the triceps brachii, and the brachioradialis with and without the cock-up splint was measured using a BTS FreeEMG 300 wireless electromyography system (BTS, Inc., Milan, Italy). [Results] The activation of the biceps brachii and the brachioradialis was significantly higher while performing the simulated feeding task with the cock-up splint than without the splint. While picking up the light and heavy cans, the activation of the brachioradialis was significantly decreased by wearing the cock-up splint. In the heavy cans task, the activation of the triceps brachii was significantly higher with the cock-up splint than without the splint. [Conclusion] This study showed that diverse muscles' activation was increased or decreased when wearing the cock-up splint while performing tasks similar to ADL. The results of this study can be used as an educational resource for therapists teaching patients about splint application and splint compliance in ADL.
[目的]本研究调查了在佩戴和不佩戴伸腕夹板进行类似于日常生活活动（ADL）的任务时，主要肘部肌肉激活情况的变化。[方法]16名参与者在Jebsen-Taylor手功能测试中执行模拟进食任务并拿起轻、重两种罐头。使用BTS FreeEMG 300无线肌电图系统（BTS公司，意大利米兰）测量佩戴和不佩戴伸腕夹板时肱二头肌、肱三头肌和桡侧腕长伸肌的激活情况。[结果]在佩戴伸腕夹板执行模拟进食任务时，肱二头肌和桡侧腕长伸肌的激活明显高于不佩戴夹板时。在拿起轻、重两种罐头时，佩戴伸腕夹板使桡侧腕长伸肌的激活显著降低。在重罐头任务中，佩戴伸腕夹板时肱三头肌的激活明显高于不佩戴夹板时。[结论]本研究表明，在执行类似于ADL的任务时，佩戴伸腕夹板会使不同肌肉的激活增加或减少。本研究结果可作为治疗师向患者传授ADL中夹板应用和夹板依从性的教育资源。
