A digital of pelvic muscle strength for evaluation of a pelvic muscle exercise (PME) program was developed with a sample of 338 incontinent women living at home. Facotors of perceived pressure, alteration of the vertical plane, and time were combined to form a 7-point scale ranging from 0 to 4. Test-restest for the anteroposterior score was r = .65, p < .01 with interrater reliability, r = .91, p < .01. Relationship to other variables and further development of th measure are discussed.
