The Evaluation of Pelvic Floor Muscle Function: A Reliability and Correlation Study
- To explore the correlations among measures of PFM strength between using vaginal palpation quantified by modified Oxford Grading Scale and Levator ani testing and manometry in PHENIX instrument;
- To determine the intra- and inter-rater reliability of PFM strength measured using manometry in PHENIX instrument.

Detailed Description
This is a study using a randomized crossover blind method.All the volunteers are divided into 2 groups randomly. At the first time, a gynecological physician evaluates patient's pelvic floor muscle strength by vaginal palpation based on modified Oxford Grading Scale(MOS) and Levator ani testing(LAT) without telling patient her result, and record it on a unique paper other than in the Case Report Form.
At the same day, patient will be tested by inspector A or B randomly twice with the PHENIX instrument.A 5 minutes' interval is needed between two tests in order to reduce the possibility of fatigue of pelvic floor muscles. The outcome is secretive to the patient as well.
A second time evaluation is required in 3 days' later by a different inspector from the first time.(interrater and intrarater) All the data including strength of MOS and LAT, the outcomes by inspector A and B, cannot be collected together and told to the patient until she finished the whole process.
Pelvic floor muscle training is not permitted during the evaluations.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: GROUP A1
In GROUP A1, participants are all healthy women.A gynecological physician evaluates the participant's pelvic floor muscle strength by vaginal palpation based on modified Oxford Grading Scale(MOS) and Levator ani testing(LAT) without telling the participant her result, and records it on a unique paper other than in the Case Report Form.Then inspector A will test them twice using the PHENIX instrument with a 5 minutes' interval at the same day.After three days,participants in group A1 will be tested by inspector B twice in the same way as what they have done the first day.

the PHENIX instrument was designed and produced for sensing muscle activity with surface electrodes, pressure probes and external captors,so it could test biological signals of pelvic floor muscle in human body.

Experimental: GROUP A2
In GROUP A2,participants are all healthy women.A gynecological physician evaluates participant's pelvic floor muscle strength by vaginal palpation without telling the participant her result, and records it on a unique paper other than in the Case Report Form as what GROUP A1 do.Then it is inspector B who will test them twice using the PHENIX instrument with a 5 minutes' interval at the same day.Three days later,participants in group A2 will be tested by inspector A twice in the same way as what they have done the first day.
