A digital test for pelvic muscle strength in women with urinary incontinence.
This article reports further experience with a Version 2 digital test performed on 208 community-residing women, 25 to 87 years old. Test-retest (n = 208) and interrater reliability (n = 36) scores for pressure, displacement, and duration were r = .54, .51, and .53 and r = .67, .73, and .55, respectively. Interrater reliability percentage agreement figures were exact for 94% of the women on pressure and 67% on displacement. With duration permitted to vary by 1 second, agreement was 75%. Validity was tested using vaginal electromyography scores with correlation coefficients ranging from .37 to .63. A weak but significant correlation was found between the digital score and the stand-up test pad gain (r = -.12). No significant relationship was found between the digital test and a history of being able to stop the urine stream or other leakage measures. To address limitations in Version 2, a third version of the digital scale is proposed.
