問題背景:復健治療中的肌力訓練常用來改善肌肉力量、耐力不足等問題,但是傳統的肌力訓練僅能粗分各項控制的參數,而且無法精確的評估肌力表現;等速訓練設備雖然可以量測肌力表現,卻僅能做單一關節活動,且機器龐大、昂貴,造成臨床上無法普及。目的:設計一臨床復健所需肌力評估與訓練的機電整合控制系統。材料與方法:本研究在硬體部分是採用步進馬達、力感測器與傳統的滑輪機構,軟體的部分使用視窗程式設計,配合訊號整合電路,作運動流程控制以及肌力評估參數的計算。最後以11受測者實際操作,比較本研究之系統與等速測力儀KINCOM評估結果的相關性檢定。在統計上利用Person Correlation來考驗兩者之相關,顯著水準定在α<0.01。結果:系統測試結果顯示,在等長、等張和等速運動下,力量改變與馬達的動作皆符合運動的流程設計,在向心收縮與離心收縮的評估參數結果都與KINCOM有顯著的相關(p<0.01)。討論與結論:本研究實現了以步進馬達、力感測器和滑輪組所組成的肌力訓練系統,可以將運動時所提供的阻力作細分量化,配合電腦的控制達成整合運動處方設定,並且可以實行多關節運動,比目前的等速測力儀更經濟。
Background: Recovery of muscle strength is usually a necessary component in the rehabilitation program for patient with musculoskeletal problem. In clinic, isotonic and isokinetic equipments are commonly used to assist patients reconditioning their muscle function. Two problems exist in these two equipments, isotonic equipment can not be used to measure muscle’s force-time performance. Although isokinetic equipment provides function in measuring force-time performance, it can only be used to measure single joint motion. Objectives: The purpose of this study was to develop an electromechanical system that could be used to quantitatively measure muscle’s force-time and force-profile characteristics. Methods: Four major components were used in this system. Those were strain gauge, step-motor, signal conditioning circuit, and mental frame with pulleys and cables. User’s force output was measured by the strain gauge. Resistance was given by step-motor device. All input and output signal were processed by using PSOC microprocessor chip. A computer program with windows interface was designed for manipulation entire system. Eleven subjects voluntarily participated in this study. In order to validate examine the relationship between two systems’ outputs. Results: The system could be successively used to measure muscle isometric, isotonic and isokinetic contraction. Muscle test result obtained from Kin Com were significantly correlated with results obtained from our system (p<0.01). Discussions and conclusions: Electromechanical system developed in this study could be used in measuring muscle isometric, isotonic and isokinetic contraction. This system also can be used to measure force output from specific-movement; such as lower extremity’s sit-up stand movement, and upper extremity’s throwing movement.
