摘要: | 乳癌患者在手術完畢後,必須進行一系列復健運動以維持正常肩關節的活動度。此舉不僅可避免諸多的術後併發症,同時也能保有維持日常生活的肩關節功能。然而,復健伴隨而來的不舒適感以及無立即成效的特性,讓病患漠視它的必要性而導致長期復健運動處方的成效不彰。因此,迫切需要一個機制能夠評估身體復原的狀況,提升病患自身健康狀態的認知,進而鼓勵其積極地持續復健運動。
本研究以加速度器與曲率檢知器的訊號為基礎,利用線性迴歸模型與監督式學習方法實作出肩關節功能性評估系統。系統依據病患做出的六種臨床上評估肩關節功能性的運動,偵測出最穩定的肩關節活動度,並以此為基準評估日常生活行為的功能性。目的在反映病患身體復原的程度,提升病患對自我身體健康狀態的認知。在系統效能評估上,對於肩關節活動度的判斷均方誤差角度在六類評估動作中皆小於12度。爾後,透過``乳癌防治基金會'的協助,實際請求病患嘗試此系統,獲得病患與物理治療師一致的正面肯定,證實了此系統在真實世界的可行性。 Persistent rehabilitation can help post-operation patients maintain functionality of shoulder motion. It prevents body from more severe symptoms such as lymphedema and keeps well capability of doing activities of daily life. However, lots of patients always ignore the importance of persistent rehabilitation due to the deficiency of self-awareness about body status. It makes patients do not spontaneously continue rehabilitation for at least one year. Therefore, it is necessary to provide a mechanism that makes patients gain much incentive to motivate them to do rehabilitation more frequently. Based on the signals from accelerometer and bending sensor, this thesis adopts the supervised learning technique to implement the shoulder functionality evaluation system with linear regression model. The system identifies the most stable shoulder range of motion according to the six shoulder evaluation exercises performed by patients. It also shows the assessment for capability of activities of daily life in order to instantly boost self-awareness about shoulder health status. Not only the feasibility study shows that the mean square error in prediction angle of shoulder range of motion is below 12 degree, but also the system obtains the positive affirmation from real-world patients and physical therapist after they try out the system. |
