A method and a device for diagnosing brain injury (e.g. concussion) based on analysis of electromyogram (EMG) signals and presence of neurological modulation impairment of motor activity are described. The method consists of recording specific EMG signals under defined conditions, processing the acquired EMG signals, extracting the relevant information, and making diagnosis of brain injury and disorders that are associated with brain pathology. Specifically, the steps and device involved in the method include placing an EMG electrode set on the subject’s body area, acquiring EMG signals from a subject’s muscle(s) undergoing contraction, processing the acquired EMG signals using a signal processing algorithm that includes Fourier transformation. The resulting EMG data with a frequency domain (frequency power spectra) are then analyzed in comparison with databases stored in the device and used to determine anomaly of diagnostic value in the EMG power spectra from subjects. A diagnosis can be made based the altered EMG frequency power spectra that reflect the neurological modulation impairment of motor neurons. The diagnostic value, determination, management suggestions are displayed on the device.本案描述基於肌電圖(EMG)訊號之分析及運動活動之神經調製障礙的存在來診斷腦損傷(例如，腦震盪)的方法及裝置。該方法由以下者組成：在所界定的條件下記錄特定EMG訊號；處理該等所獲取的EMG訊號；提取該相關資訊；以及進行與腦病理相關聯之腦損傷及故障診斷。具體而言，該方法所涉及的步驟及裝置包括：將一EMG電極組置放於受試者之身體區域上；自該受試者之經曆收縮之肌肉獲取EMG訊號；使用包括傅立葉轉換之一訊號處理演算法來處理該等所獲取的EMG訊號。隨後，將所得之具有一頻域(頻率功率譜)之EMG資料與儲存於該裝置中之資料庫進行比較來加以分析且用來判定來自受試者之該EMG功率譜中之診斷值的異常。可基於反映運動神經元之神經調製障礙的該變化的EMG頻率功率譜來做出一診斷。該診斷值、判定、管理建議係顯示於該裝置上。
