A determination system of cervicalstrain comprises a cervical monitoring device which can be worn like a necklace. The cervical monitoring device can detect a neck’s rotation and bending then outputs a record of the rotation and bending to a cloud database and a receiving device. Furthermore, a magnetical connecting part can make user wearing the cervical monitoring device easily. This invention solves the drawbacks of prior art which needs to estimate the cervical bending by skiagraph. Besides that, this invention also performs a revising method which can detect an exercise statement of the cervical to get a precaution.一種人體頸椎勞損判定系統,其中包含一頸椎監測裝置及與該頸椎監測裝置訊號連接之雲端資料庫,而該頸椎監測裝置可如項鍊般穿戴於使用者身上,進而達到即時測量使用者的頸部轉動與彎曲狀態的功效,並將彎曲與轉動運動狀態記錄後輸出至該雲端資料庫及該接收裝置,而連接於該頸圈之間具有磁性的結合件讓使用者可便利的穿戴;而本新型解決現有必須透過X光照片判斷頸椎是否變形之既有技術限制問題;此外,本新型提供一種校正方法,可相對精確測量頸部運動狀況;提供統計與警示輸出,讓使用者可以隨時掌控頸椎運動狀況,藉此可以達到預防功效。10‧‧‧頸椎監測裝置11‧‧‧頸圈13‧‧‧監測本體15‧‧‧結合件15‧‧‧結合件151‧‧‧連接器1511‧‧‧L型切面1512‧‧‧端子1513‧‧‧插座
