Functionally, contraction of pelvic floor muscles prevents unintentional leakage of excretions, while voluntary evacuation entails relaxation of the muscles. Many of serious problems can be caused by dysfunction of pelvic floor muscles, such as urinary incontinence and/ or voiding dysfunction. Widespread attention has been paid to significance of pelvic floor muscles, both functional and pathophysiological aspects. Unfortunately, most study was confined merely to force measurement before fully understanding of the relationship between muscle force of pelvic floor and severity of functional impairments. Up to the present, little effort has been driven to physiological mechanisms of strengthening and force regulation for the pelvic floor muscle, though they have much been clarified in the skeletal muscles. In order to gain a better insight into function of the pelvic floor muscles must rely on a new instrument, which is equipped with EMG/ piezo-resistance sensor/position to characterize sophisticatedly contraction dynamics of the muscles in a multi-facet dimensionality. In this study, we will continue to develop a novel Bluetooth-based wireless data acquisition system, can simultaneously record electromyography activity and pressure of vagina with the position related to pubic bone during PFM contraction. The physiological mechanisms of strengthening and force regulation for the pelvic floor muscle can be investigated by analyzing the simultaneously recorded EMG and force signals. Recording the position of vagina related to pubic bone through the accelerometer could give us extra information about the role of PFM contraction in control of pelvic floor and relative organs and the continence mechanism. These recording signals could be wirelessly transmitted to a nearby host station via low-power Bluetooth modules which enabled the convenience and portability for dynamical recording of pelvic floor functions.骨盆底肌肉群除了提供腹腔臟器的支撐，更是排尿、排便以及生殖道出口 的把關。經由提肛肌的收縮與放鬆，膀胱及直腸排泄物平常不會外漏，而在需 要排泄時又能夠充分的放鬆以便排空。當骨盆底肌肉功能異常時將導致骨盆底 功能障礙或失調。世界各國越來越多學術單位或研發團體投入研究骨盆底肌功 能的探討，顯見骨盆底肌肉的收縮控制在骨盆底功能障礙的病理生理機轉中的 重要性。然而多數的研究只測量單一生理訊號(力量)，其結果都只局限於比較力 量大小與骨盆底功能障礙或失調嚴重度之間的關係。四肢骨骼肌肌力控制的主 要機制，已被充分的研究，但目前並無學者探討骨盆底肌肉肌力控制的主要機 制及肌肉功能的控制改善機轉。 一個結合多種生理訊號測量(肌電訊號、壓力與位移)於一的多通道骨盆底 功能測量儀器，可同時量測左右骨盆底肌肉的肌電及肌側壓力訊號等生理參 數，將有助於分析了解肌力控制機轉。加上內建三軸加速度計於測量探頭中， 可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影響， 提供不同的肌力表現(力量強相對於力量弱或左右不對稱的力量)對陰道在空間 中位移影響的分析，則助於了解骨盆底肌在禁尿機轉中實際作用。 本計劃將以現有進度為基礎(1) 整合EMG 電極、壓力測量與位移感測量 於一的多通道骨盆底功能測量儀器，如此除可同時觀測肌肉收縮時肌力控制的 調控機轉，並可同時量測肌肉縮收對禁尿機轉的影響；(2)改良傳統儀器在有線 傳輸上所造成的不便，利用具備體積小、低功率傳輸的藍芽模組來達到短距離 的無線傳輸，完成可攜式的穿載裝置，並藉由訊號處理技術分析所收集之訊號， 除了可以探討正常人、尿失禁婦女及排尿障礙婦女的骨盆底肌肌力控制機制之 外，進一步可以進行動態評估及不同治療效果的評估。骨盆底功能障礙骨盆底肌評估表面肌電圖電極壓力測量位置測量三軸加速度計藍芽無線pelvic floor dysfunctionpelvic floor muscleevaluationelectromyogrampiezo-resistance sensoraccelerometerpositionblue teethProject
