PROBLEM TO BE SOLVED: To provide an arm cover of an artificial arm which can surely measure myogenic potential, has flexibility enough to follow the movement of the body, and prevents wiring to be connected to a detection electrode portion from diverting from a prescribed position and getting exposed.SOLUTION: The arm cover 10 of an artificial arm for measuring myogenic potential includes at least the detection electrode portion 3 measuring myogenic potential, the wiring 2 transmitting signals from the detection electrode portion 3 and a textile 1 into which the wiring 2 is woven.COPYRIGHT: (C)2011,JPO&INPIT【課題】筋電位を確実に測定することができ、身体の動きに追従する柔軟性を有すると共に、検出電極部に接続する配線が所定の位置から離脱して露出するようなことがない筋電位測定義手用アームカバーの提供。【解決手段】筋電位を測定する検出電極部3と、該検出電極部3からの信号を伝送する配線2と、該配線2を織り込んだテキスタイル1とが少なくとも備えられたことを特徴とする筋電位測定義手用アームカバー10。【選択図】図1
