STUDY DESIGN The seat and back contact force, pressure distribution, lumbar lordosis, and low back muscle activities associated with a new seat design with adjustable ischial support and backrest were investigated using kinematic, kinetic, electromyographic, and radiographic measurements. OBJECTIVES To investigate the biomechanical effects of adjusting ischial and backrest supports during sit...

Tension-free vaginal mesh (TVM) surgery is a common and minimally invasive procedure for pelvic organ prolapses. Since commercial kits are not readily available in Japan, we have planned tailor-made mesh by information of each patient before every TVM surgery. The aim of this report is to inform methods to design mesh for individual patients with pelvic organ prolapses. We also investigated the...

Pudendal nerve entrapment syndrome is an unusual cause of chronic pelvic pain. We experienced a case of pudendal neuralgia associated with a ganglion cyst. A 60-year-old male patient with a tingling sensation and burning pain in the right buttock and perineal area visited our outpatient rehabilitation center. Pelvis magnetic resonance imaging showed the presence of multiple ganglion cysts aroun...

Pudendal nerve block is performed to confirm the diagnosis of pudendal neuralgia. Many physicians and patients are hesitant to pursue diagnostic nerve blocks to confirm the diagnosis of pudendal neuralgia secondary to significant patient discomfort, the need for special equipment, and the risk in the traditionally described approach. Objective: To describe a novel technique for pudendal nerve b...

INTRODUCTION In this study we aimed to determine whether high-resolution ultrasound (US) can identify the pudendal nerve and its terminal branches. We also attempted to identify the best approach for visualizing these structures. METHODS Normal anatomy of the pudendal nerve was evaluated in 3 cadavers and 20 healthy volunteers proximally at the level of the ischial spine and distally with low...

OBJECTIVE Our purpose was to assess the structural integrity of individual elements of the urethral and anterior vaginal wall support system. STUDY DESIGN Notes were made during retropubic operations for cystourethrocele and stress incontinence in 71 women aged 52 +/- 12.4 (SD) years. Vaginal support was assessed with the Baden-Walker system with the following average findings: urethra 1.9 +/...

Chronic pelvic pain syndrome is a conundrum that may be explained partly by pudendal nerve entrapment (PNE), which causes neuropathic pain. In men with PNE, aberrant development and subsequent malpositioning of the ischial spine appear to be associated with athletic activities during their youth. The changes occur during the period of development and ossification of the spinous process of the i...

BACKGROUND Symptomatic femoroacetabular impingement is a known prearthritic condition. Impingement morphology is poorly defined in the adolescent population. The purpose of this study was to document the prevalence of radiographic impingement morphology in adolescents with no symptomatic hip problems. METHODS Ninety anteroposterior images of the hip in forty-five consecutive adolescents with ...

BACKGROUND Femoroacetabular impingement (FAI) is a painful and limiting condition of the hip that is often seen in young athletes. Previous studies have reported a higher prevalence of this disorder in male athletes, but data on the structural morphology of adolescent and young adult female athletes, specifically those involved in dance, are lacking. PURPOSE (1) To investigate the radiographi...
