Provided is a user-centered biofeedback belly band in which a patient having back pain wears on belly to induce active contraction of deep abdominal muscle, wherein the belly band (1) of the present invention comprises: a detecting means (4) which is installed in a band unit (2) to detect a contraction and relaxation of abdominal muscle by a stretching and contraction of the band unit (2)； and a hearing notice means (5) which is configured to notify a relaxation of the abdominal muscle with hearing by a detection of the detecting means (4). More specifically, the detecting means (4) comprises a casing (7) having one end of the band unit (2) fixed thereto, a plurality of fixing detecting pieces (10) sequentially installed in the casing (7), and an operation detecting piece (11) selectively concatenated to the fixing detecting pieces and installed in the end of the band unit (2) having the other end connected to an elastic member (9) fixed into the casing (7) to connect electrical contacts. The belly band of the present invention audibly or vibrationally realizes a biofeedback technology, thereby continuously and effectively supplying an exercise effect for deep abdominal muscle regardless of time and place. In addition, the belly band has a high utilization value as an active rehabilitation instrument which allows a user to exercise for oneself, an obesity prevention effect through deep abdominal muscle strengthening exercise, and an improved backbone stability actively obtained by a self-contraction, whereby original reasons of back pain can be solved.본 발명은 허리 통증이 있는 환자가 복부에 착용하여 심부 복부근을 능동적으로 수축을 유도할 수 있는 사용자 중심의 바이오 피드백 복대를 제공코자 하는 것이다.즉, 본 발명의 복대(1)는 밴드부(2)에 복부근의 수축 및 이완을 밴드부(2)의 신장, 수축으로 감지하기 위해 설치되는 감지수단(4)과； 상기 감지수단(4)의 감지작동에 의해 복부근이 이완 시 청각으로 이를 고지할 수 있도록 청각고지수단(5)과； 상기 감지수단(4)은 밴드부(2) 일단이 고정되는 케이싱(7)과, 상기 케이싱(7) 내부에 순차적으로 설치되는 복수개의 고정감지편(10)과, 상기 고정감지편(10)에 선택적으로 연접되어 전기적인 접점을 연결할 수 있도록 케이싱(7) 내부에 고정된 신축부재(9)와 타단이 연결된 밴드부(2) 단부에 설치되는 가동감지편(11)으로 이루어지는 것을 특
