Abstract：
UNASSIGNED: The study aims to develop a finite element model of the pelvic floor and thighs of elderly men to quantitatively assess the impact of different pelvic floor muscle trainings and the urinary and defecation control ability.
UNASSIGNED: A finite element model of the pelvic floor and thighs of elderly men was constructed based on MRI and CT. Material properties of pelvic floor tissues were assigned through literature review, and the relative changes in waistline, retrovesical angle (RVA) and anorectad angulation (ARA) to quantitatively verify the effectiveness of the model. By changing the material properties of muscles, the study analyzed the muscle strengthening or impairment effects of the five types of rehabilitation training for four types of urination and defecation dysfunction. The changes in four outcome indicators, including the retrovesical angle, anorectad angulation, stress, and strain, were compared.
UNASSIGNED: This study indicates that ARA and RVA approached their normal ranges as material properties changed, indicating an enhancement in the urinary and defecation control ability, particularly through targeted exercises for the levator ani muscle, external anal sphincter, and pelvic floor muscles. This study also emphasizes the effectiveness of personalized rehabilitation programs including biofeedback, exercise training, electrical stimulation, magnetic stimulation, and vibration training and advocates for providing optimized rehabilitation training methods for elderly patients.
UNASSIGNED: Based on the results of computational biomechanics, this study provides foundational scientific insights and practical recommendations for rehabilitation training of the elderly\'s urinary and defecation control ability, thereby improving their quality of life. In addition, this study also provides new perspectives and potential applications of finite element analysis in elderly men, particularly in evaluating and designing targeted rehabilitation training.

摘要：
■该研究旨在开发老年男性盆底和大腿的有限元模型，以定量评估不同盆底肌肉训练的影响以及泌尿和排便控制能力。
■基于MRI和CT构建了老年男性盆底和大腿的有限元模型。盆底组织的材料特性通过文献综述,以及腰围的相对变化，后膀胱角度（RVA）和非直肠角度（ARA）定量验证了模型的有效性。通过改变肌肉的物质特性，该研究分析了五种康复训练对四种排尿排便功能障碍的肌肉增强或损伤效果。四个结果指标的变化，包括后膀胱角度，非矩形角度，压力，和应变，进行了比较。
■这项研究表明，随着材料性能的变化，ARA和RVA接近其正常范围，表明泌尿和排便控制能力增强，特别是通过有针对性的肛提肌锻炼，肛门外括约肌,和盆底肌肉.这项研究还强调了个性化康复计划的有效性，包括生物反馈，运动训练,电刺激,磁刺激,和振动训练，并倡导为老年患者提供优化的康复训练方法。
■基于计算生物力学的结果，本研究为老年人排尿和排便控制能力的康复训练提供了基础性的科学见解和实践建议,从而提高他们的生活质量。此外,本研究还提供了有限元分析在老年男性中的新观点和潜在应用，特别是在评估和设计有针对性的康复训练。
