Study summary

The aim of this study is to T to compare the effectiveness of producing a pelvic floor muscle contraction by different verbal instruction. Pelvic floor muscle contraction will be measured displacement of the pelvic floor when imaged on ultrasound.

Read the detailed description

This study will examine pelvic floor muscle contraction following different verbal instructions. This is a cross-sectional exploratory study. 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.

The participants will be divided into 2 groups randomly. Both groups will be given three 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.

Study arms

  • Experimental
    Group A

    The participants will be verbal instructed to contract the pelvic floor muscle with the following sentences: 1. "squeeze the pelvic floor muscles" 2. "squeeze and lift the pelvic floor muscles as if stopping the flow of urine" 3. "Take a moderate breath in, let the breath out, draw in and lift your pelvic floor." 4. "contract all of the above together"

    Diagnostic Test: verbal instruction

  • Experimental
    Group B

    The participants will be verbal instructed to contract the pelvic floor muscle with the following sentences: 1. "squeeze the pelvic floor muscles" 2. "squeeze the anus" 3. "Take a moderate breath in, let the breath out, draw in and lift your pelvic floor." 4. "contract all of the above together"

    Diagnostic Test: verbal instruction

Interventions

  • Diagnostic testverbal instruction

    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.

What researchers measure

Primary outcomes

  1. urinary bladder displacement in millimeters during first verbal instruction

    bladder displacement will be measured via diagnostic ultrasound using the on screen caliper tool

    Time frame: up to 6 months

  2. urinary bladder displacement in millimeters during second verbal instruction

    bladder displacement will be measured via diagnostic ultrasound using the on screen caliper tool

    Time frame: up to 6 months

  3. urinary bladder displacement in millimeters during third verbal instruction

    bladder displacement will be measured via diagnostic ultrasound using the on screen caliper tool

    Time frame: up to 6 months

Secondary outcomes

  1. pelvic floor muscles endurance of contraction in seconds

    time of muscle contraction will be measured during the last contraction in each instruction

    Time frame: up to 6 months

  2. demographic self reported questionnaire regarding height

    height in meters

    Time frame: baseline

  3. demographic self reported questionnaire regarding weight

    weight in kilograms

    Time frame: baseline

  4. self reported questionnaire regarding physical activity

    number of practice per week

    Time frame: baseline

  5. questionnaire regarding symptoms of urinary incontinence = International Consultation on Incontinence Questionnaire - Short Form

    scale range 0-21 points. higher values represent worse outcome

    Time frame: baseline

  6. BMI

    measured in kg/m\^2 and calculated from the reported values of weight and height

    Time frame: baseline
