Stafford R, Ashton-Miller J, Constantinou C, Hodges P
Urology . 2013 Jan; 81(3):685-9. PMID: 23332998
Objective: To develop a method to quantify displacement of pelvic structures during contraction of the pelvic floor muscles from transperineal ultrasound images in men and investigate the reliability of the...

Stafford R, Ashton-Miller J, Constantinou C, Hodges P
J Urol . 2012 Aug; 188(4):1224-30. PMID: 22902016
Purpose: Transperineal ultrasound imaging enables the minimally invasive assessment of pelvic floor muscle function. Although commonly used in women, the approach has rarely been reported in men. This approach has...

Hasegawa S, Yoshida Y, Wei D, Omata S, Constantinou C
Stud Health Technol Inform . 2011 Feb; 163:218-23. PMID: 21335792
We simulated the way that pelvic floor muscles (PFM) generate zonal compression on the vagina and urethra in order to maintain urinary continence. Raw data were obtained using a probe...

Constantinou C, Korenblum D, Chen B
Stud Health Technol Inform . 2011 Feb; 163:138-43. PMID: 21335777
Visualization of the geometric deformation and associated displacement patterns of tubular abdominal organs to mechanical stimuli provides a quantitative measure that is useful in modeling their elastic properties. The origin...

Lovegrove Jones R, Peng Q, Stokes M, Humphrey V, Payne C, Constantinou C
Eur Urol . 2009 Jun; 57(6):1101-10. PMID: 19560261
Background: Current measurement tools have difficulty identifying the automatic physiologic processes maintaining continence, and many questions still remain about pelvic floor muscle (PFM) function during automatic events. Objective: To perform...

Constantinou C
Eur J Obstet Gynecol Reprod Biol . 2009 Mar; 144 Suppl 1:S159-65. PMID: 19303690
In this review the diagnostic potential of evaluating female pelvic floor muscle (PFM) function using magnetic and ultrasound imaging in the context of urodynamic observations is considered in terms of...

Rahmanian S, Jones R, Peng Q, Constantinou C
Stud Health Technol Inform . 2008 Apr; 132:390-5. PMID: 18391328
Real time ultrasound imaging is one of the many ways to clinically evaluate the anatomical and functional condition of female pelvic floor in patients with urinary incontinence. Reflex arc testing...

Shishido K, Peng Q, Jones R, Omata S, Constantinou C
J Urol . 2008 Mar; 179(5):1917-22. PMID: 18353401
Purpose: We characterized the vaginal pressure profile as a representation of closure forces along the length and circumference of the vaginal wall. Vaginal pressure profile data were used to test...

Murayama Y, Omata S, Yajima T, Peng Q, Shishido K, Peehl D, et al.
Annu Int Conf IEEE Eng Med Biol Soc . 2007 Nov; 2007:5803-6. PMID: 18003332
What is it that the clinician "feels" during a digital rectal examination? To answer this question, it is necessary to measure the elastic properties of the prostate and verify the...

Peng Q, Jones R, Shishido K, Omata S, Constantinou C
Physiol Meas . 2007 Nov; 28(11):1429-50. PMID: 17978426
Clinically the strength of the contraction of the female pelvic floor is qualitatively evaluated by vaginal tactile palpation. We therefore developed a probe to enable the quantitative evaluation of the...
