概括
跑步时的骨盆底负荷没有影响骨盆器官支变化或尿液泄漏. 这项研究发现,跑步强度与女性跑步者的这些结果之间没有联系.
科学领域:
- 生物力学 生物力学
- 泌尿和妇科 泌尿和妇科
- 运动医学 运动医学
背景情况:
- 在女性运动员中,跑步可能导致盆地肌肉 (PFM) 功能障碍和压力尿失禁 (SUI).
- 了解运行生物力学与PFM反应之间的关系对于预防和管理伤害至关重要.
研究的目的:
- 为了确定在标准化跑步方案期间的骨盆底负荷是否与骨盆底形态学,PFM功能或失禁体重增加的直接变化相关.
- 调查跑步诱导性SUI (RI-SUI) 的和没有跑步者的这些关联的潜在差异.
主要方法:
- 有和没有RI-SUI的成年女性跑步者 (n=38) 进行了37分钟的跑步机跑步.
- 使用阴道压力传感器和骨盆加速度计测量了盆地负荷.
- 骨盆形态测量和PFM功能通过超声波和动力测量评估了跑前和跑后的情况.
- 尿泄漏的量度是通过失禁的体重增加.
主要成果:
- 运行后,无论RI-SUI状态如何,都观察到升降器间隙尺寸增加和膀下部部位置增加.
- 较高的骨盆加速与被动PFM刚度的降低相关,但与形态变化或PFM力没有相关.
- 骨盆底负荷暴露量与PFM力产生能力的变化之间没有发现任何关联.
- 在患有RI-SUI的跑步者中,较慢的矢量加速与更大的子体重增加有关.
结论:
- 跑步期间的骨盆底负荷的程度似乎不会影响立即减少静态的骨盆器官支.
- 在这个队列中,运行负载大小与尿液泄漏量没有相关性.
- 进一步的研究可能会探索特定的跑步模式或其他影响PFM对运动反应的因素.

Muscles of the Pelvic Floor and Perineum
2.2K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Urodynamic Studies: Uroflowmetry
652
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Assessment of the Rectum and Anus
415
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
