2026-11-092026-11-09https://scholars.csmu.edu.tw/handle/123456789/38778In order to gain a better insight into function of the pelvic floor muscles (PFM), an integrative instrument with multi-facet dimensionality was designed by collaborating EMG and position sensors for detecting contraction dynamics of the muscles. With the surface electromyography and 3D accelerometer sensing technology, a novel wireless data acquisition system with convenience and portability to record the spatial movements of the vagina in relation to pubic bone and concurrent activities of the bilateral PFM was developed. This device will be used in this proposed study to contrast the functional difference of the PFM, between healthy and pelvic floor dysfunction women, including contractibility and endurance of the muscle. Both voluntary maximal contraction and reflexive contraction during cough condition will be evaluated in the supine position. In addition, the gravitational influence on contraction dynamics of the PFM, the same tests will be examined in the upright (anti-gravity) position. The subjects with different pelvic floor dysfunction will receive either PFM exercise or pelvic floor electrical stimulation or both for 6 weeks, according to their problems. The effects of therapeutic interventions will be validated, in terms of muscle tone and contraction dynamics. This innovation will facilitate a better understanding of the functional role of the PFM for continence mechanisms, as well as contraction dynamics, and force regulation of the muscle. The proposed study will add to in-depth understanding of pathological mechanisms and better treatment strategies of PFM dynfunction for clinicians. Also, the proposed study will bridge instrumental design and clinical evaluation for existing PFM dysfunction.本研究擬藉由一個整合肌電訊號與慣性感測器的新型測量儀器，同時量測骨盆底 肌收縮時的肌肉活動與陰道位移，以深入了解女性骨盆底肌功能障礙的病理收縮機轉。 測量系統位於陰道探頭內部，分別有左右側的雙極式電極，以分別記錄左右側骨盆底肌 電訊號，同時在探頭內的中段位置植入高靈敏度之慣性感測器(三軸加速規以及陀螺 儀)，以同步紀錄骨盆底肌在活動過程中，造成陰道與附近結構相對於恥骨移動與傾斜 角度變化，提供不對稱與失能骨盆底肌的表現對陰道在空間中的影響，經藍芽無線傳輸 動態收縮的數位訊息，以瞭解肌肉無力與肌肉過度用力無法放鬆病患的骨盆底肌動態控 制與禁尿機轉中實際作用。 此評估系統將會被用來評估健康受測者與骨盆底功能障礙受測者(含肌肉無力與肌 肉過度用力無法放鬆兩種病徵)的骨盆底肌表現。在受測者平躺姿勢下或在直立的姿勢 下，評估骨盆底肌自主最大收縮、咳嗽時的反射性收縮的收縮特性與耐力特性；及重力 對骨盆底肌的功能表現的影響。此外，患有骨盆底功能障礙的受測者將依其問題分別或 同時接受六星期的骨盆底肌運動或骨盆底電刺激治療，藉由比較治療前、治療後的肌肉 張力及收縮動態，以了解保守療法對不同骨盆底功能障礙的治療效果。此部分的研究除 了加深臨床人員了解其致病機轉與治療決策外，也將完整落實本團隊人員於評估系統設 計與研發在臨床評估上的應用。骨盆底功能障礙骨盆底肌評估表面肌電圖電極加速度計藍芽無線陰道探頭慣性感測器pelvic floor dysfunctionpelvic floor muscleevaluationelectromyogramaccelerometerBluetoothvaginal probeinertial sensorsProject
