Introduction and hypothesis
The aim of this study is to compare the Colpexin pull test (CPT) with the Oxford muscle grading scale (OMGS) in assessing pelvic floor muscle strength.
Methods
In phase 1, 15 asymptomatic women underwent OMGS and CPT using three different spheres to select the ideal size. CPT values as well as patient/examiner comfort and ease of CPT performance were recorded. In phase 2, 30 women with stress urinary incontinence underwent CPT and OMGS by two examiners during two separate sessions. Statistical analysis was performed.
Results
In phase 1, the 36-mm sphere was selected based on resting (p < 0.001), contraction CPT (p < 0.001), patient ease (p = 0.018), patient comfort (p = 0.004), and examiner comfort (p < 0.001). In phase 2, there was good intra-rater and inter-rater agreement in maximum CPT. Both tests were positively correlated (r = 0.50, p < 0.001).
Conclusion
CPT is an objective measure of pelvic floor strength and provides consistent, reproducible results.
