Verbal Instruction for Contraction Pelvic Floor Muscles Among Males

The aim of this study is to compare the effectiveness of different verbal instruction on pelvic floor muscle contraction among males. Pelvic floor contraction will be measured via ultrasound.

This study will examine pelvic floor muscle contraction following six different verbal instructions among males. Physical-therapy students will be recruited to complete a survey and non-invasive transabdominal ultrasound assessment. A bladder filling protocol will be implemented to ensure subjects will have sufficient fluid in their bladders to allow clear ultrasound imaging. This protocol involved subjects consuming 600-750 ml of water in a 1 hr. period. The participants will be tested in a crook-lying supine position with a pillow under their heads for comfort. All participants will be given six different verbal instructions to contract pelvic floor muscles. Each contraction will be performed 3 time with rests of 10 sec between contractions. While the first 2 contractions for each verbal instruction will be held for 3 sec. the last contraction will be held as long as the participant can conduct and the time of contraction will be measured as well. The pelvic floor contraction will be measured by assessing bladder displacement via diagnostic ultrasound. To image the pelvic floor a 5 MHz curved linear array transducer (Mindray M5) will be placed in the transverse plane immediately suprapubically over the lower abdomen angled at 15-30 degrees from the vertical. An on screen caliper and measurement tool will be used to measure bladder displacement.

The participants will be verbal instructed to contract the pelvic floor muscle with the following sentences: "squeeze the pelvic floor muscles". "squeeze and lift the pelvic floor muscles as if stopping the flow of urine" "Take a moderate breath in, let the breath out, draw in and lift your pelvic floor." ""squeeze the anus" "shorten the penis" "elevate the scrotum"

Verbal instruction for pelvic floor contraction will be given to participants. Ultrasound examination will be conducted to asses urinary bladder displacement being a marker for pelvic floor muscle function.
