- Abstract
The aim of this study was to investigate the intra-rater and inter-rater reliability of digital pelvic floor muscle strength assessment by physiotherapists participating in a multicentre study of the management of female stress urinary incontinence. Pelvic floor muscle strength was assessed and rated according to the modified Oxford scale. Intra-rater reliability for the primary author and inter-rater reliability between the primary author and fifty participating physiotherapists was determined. Testing was conducted at six sites across Australia and data from all sites was aggregated for overall analysis. Intra-rater agreement was 93% (n=14), Kappa coefficient 0.9, P<0.001 and weighted Kappa 0.4. Inter-rater agreement was 56% (n=352), Kappa coefficient 0.4, P <0.001 and weighted Kappa 0.4. However, when inter-rater agreement was broadened to include one grade higher or lower, agreement increased to 96%. It was concluded that the physiotherapists broadly agreed in their assessment of pelvic floor muscle strength to allow confidence in their baseline assessment for clinical decision-making.
