PROBLEM TO BE SOLVED: To obtain a nerve adjustment effect by an afferent input to the central nerve system through the sensorial branch while carrying out training of contracting a tongue, a group of suprahyoid muscles, a pharyngeal muscle and a laryngeal muscle by stimulating the hypoglossal nerve and the vagus nerve related to functions of the oral cavity, the pharynx and the larynx, the motor branch of the glossoepiglottic nerve and the sensorial branch using a device including a surface electrode array for stimulating a specified site of the cervical part.SOLUTION: A device 1 which includes the surface electrode array for stimulating the specified site of the cervical part is disposed and outputs a low-frequency bipolar rectangular wave of 10 Hz or below and a bipolar incremental/decremental wave having a sine wave from 2 kHz to 5 kHz as a carrier (containing triangular wave) as a stimulation wave for the preventive treatment of functional disorders of the oral cavity, the pharynx and the larynx or outputs a stimulation wave as a sin wave from 2 kHz to 5 kHz turned on for several seconds. or off for several seconds. while outputting a stimulation voltage in a range of 0 V to 40 V.COPYRIGHT: (C)2007,JPO&INPIT【課題】頸部の特定部位を刺激するための表面電極アレイを具備した装具を用い、口腔、咽頭、喉頭機能に関連した舌下神経および迷走神経、舌咽神経の運動枝、知覚枝を刺激し、舌、舌骨上筋群、咽頭筋、喉頭筋を収縮訓練を行うと共に、知覚枝を介した中枢神経系への求心性入力による神経調節効果を得る。【解決手段】頸部の特定部位を刺激するための表面電極アレイを具備した装具1を配置し、口腔、咽頭、喉頭機能障害予防治療の刺激波として10Hz以下の低周波双極性矩形波、2kHzから5kHzの正弦波を搬送波とした双極性漸増漸減波(三角派も含む)、もしくは2kHzから5kHzの正弦波を数秒ON、数秒OFFさせる刺激波を出力し、かつ刺激電圧を0Vから40Vの範囲で出力する。【選択図】図2
