The pelvic floor biomechanics and sphincter functioning are essential for understanding pelvic floor dysfunction and the pathophysiology of the pelvic organs. The pelvic floor consists of muscles, fascial connections and ligaments. The Integral Theory Paradigm (ITP) explains the musculoskeletal entity of the sphincter mechanism and the pathophysiology of pelvic organ function. The ITP explains the pelvic floor function determined by 3 directional muscle forces: forward, backwards and downward-acting muscle vector forces that form an anterior and posterior resultant. The resultant equilibrium is essential for urinary continence, voiding and defecation. Loose ligaments disturb the equilibrium of the pelvic floor's muscular function with consequences for the organ function's continence, evacuation, and sensory perception.
盆底生物力学和括约肌功能对于理解盆底功能障碍及盆腔器官的病理生理学至关重要。盆底由肌肉、筋膜连接和韧带组成。整体理论范式(ITP)解释了括约肌机制的肌肉骨骼实体以及盆腔器官功能的病理生理学。ITP解释了由三种定向肌力决定的盆底功能:向前、向后和向下作用的肌肉矢量力,这些力形成前后合力。合力平衡对于尿失禁、排尿和排便至关重要。韧带松弛会扰乱盆底肌肉功能的平衡,从而影响器官功能的节制、排空和感觉。
