膀胱過動症的核心症狀包含尿急(合併有或無急迫性尿失禁)，常伴隨頻尿及夜尿。第一線的治療還是以生活習慣調整(如飲食調整、減重)、如廁時間訓練及骨盆底肌肉訓練。第二線才會考慮抗膽鹼藥物或β3受器促進劑治療。如果藥物效果不好，可以選擇膀胱內肉毒桿菌素注射或脛神經刺激等。然而，保守治療、骨盆底肌肉訓練或電生理回饋、藥物以及手術，對於每個患者的接受度以及治療效果都不盡相同。磁波椅能夠產生與骨盆底神經肌肉的電磁場，被動式的引起骨盆底肌肉廣泛收縮，並增進尿道括約肌的強度，過往文獻甚至指出在超音波下發現有肌肥大效果。磁波椅同時對於薦神經第二至第四節，控制膀胱排尿的部分也具有調節效果。就骨盆底強化訓練而言，患者不需要像電生理回饋一樣貼電極片或者陰道探頭置放，也無電刺激的不適感，只需要坐在治療椅上面。然而目前文獻中磁波椅大多是用於輔助應力性尿失禁的改善，且研究數量不多。

此項義大利的前瞻性研究在2022年至2023年間網羅了57位有膀胱過動和急迫性尿失禁的患者。這些患者的年齡中位數為65歲，有些是經過兩線治療，或者有藥物禁忌症等。他們在一個月內接受了8次每次25分鐘的磁刺激療程。透過尿失禁影響問卷(IIQ-7)、女性性功能指數(FSFI-19)以及國際尿失禁協議-尿失禁短表格(ICIQ-UI SF)填答的治療前後差異，來審視其治療效果。結果顯示一個月後IIQ-7、ICIQ-UI SF分數顯著下降（p <0.001），以及FSFI-19顯示性功能顯著改善（p <0.001），而且治療過程中，沒有任何患者產生不良反應。此外對於整體滿意度，42 (73.7%)位患者主觀覺得病況有獲得不同程度的改善。

雖然目前磁波椅在各種治療指引中並沒有一定角色，但近幾年隨著新的研究結果出現，磁波椅提供了一個不具侵入性治療方式，不論對於初次治療，抑或難治性急迫性尿失禁患者，都有良好治療效。

Objective:
Analyze the outcomes and quality of life (QoL) impact of magnetic stimulation in women suffering from OAB syndrome associated with urinary incontinence.

Methods:
A total of 57 consecutive patients were enrolled in the study. Most women had undergone second- or third-line treatments before FMS, while others were treatment-naive due to contraindications to pharmacological treatments. They all underwent 8 FMS sessions of 25 minutes each over one month. The study measured outcomes using the Incontinence Impact Questionnaire (IIQ-7), Female Sexual Function Index (FSFI-19), International Consultation on Incontinence Questionnaire–Urinary Incontinence Short Form (ICIQ-UI SF), and the Patient Global Impression of Improvement (PGI-I) questionnaire.

Results:
The study suggests a positive impact on the quality of life, as reflected in the improvements observed in the IIQ-7 and FSFI-19 scores. FMS may be particularly beneficial in addressing the broader impact of OAB on patients' lives.

Conclusion:
Magnetic stimulation was effective in treating OAB symptoms, with prominent improvement from the questionnaire like IIQ-7 and ICIQ-UI SF scores, without any adverse effects. The mechanism is supposed to be related to suppressing the initiation of micturition. Magnetic stimulation represents a promising non-pharmacological option for the treatment of naive and refractory OAB.
