A microstimulator assembly for rehabilitation is applicable to different rehabilitation target zones according to requirements. The microstimulator assembly for rehabilitation includes a plurality of microstimulators and a second coil is provided. The microstimulators are structurally independently separated from one another and adapted to be disposed in a human body. Each of the microstimulators includes a main body, an electrode and a connection line. The main body includes a processing circuit and a first coil. The processing circuit is electrically coupled to the first coil. The electrode is electrically coupled to the processing circuit through the connection line. The second coil is adapted to be disposed on the human body and located outside the human body. When the second coil is disposed on the human body and the microstimulators are disposed in the human body, the electrodes are arbitrarily distributed in the human body and the second coil is adapted to induce at least one of the first coils such that the processing circuit corresponding to the induced first coil transmits an electrical signal to the corresponding electrode through the corresponding connection line.一種復健用微型刺激裝置組件,可依需求適用於不同的復健目標區。復健用微型刺激裝置組件包括多個微型刺激裝置與一第二線圈。這些微型刺激裝置結構上彼此獨立地分離且適於配置於一人體內。各個微型刺激裝置包括一主體、一電極與一連接線。主體包括一處理電路與一第一線圈,處理電路電性耦接至第一線圈,且電極藉由連接線電性耦接至處理電路。第二線圈適於配置於人體上且位於人體外。當第二線圈配置於人體上且這些微型刺激裝置配置於人體內時,這些電極以任意方式分佈於人體內,第二線圈適於感應這些第一線圈之至少一,使得對應於被感應之第一線圈之處理電路經由對應之連接線傳輸一電性訊號於對應之電極。
