Objective : The aim of this study was to assess the strength of pelvic floor, trunk, hip and respiratory muscles using objective methods and to study their association with the severity of stress urinary incontinence (SUI).
Material / Patients and Methods : This was a physician blinded cross sectional study including 25 women with SUI. The severity of SUI was assessed using one-hour Pad test. PFM function was assessed using the modified Oxford Scale, and electromyography. Trunk and hip muscles strength was measured using a Cybex Norm II ® dynamometer. The respiratory muscles were assessed using the maximal inspiratory and expiratory pressures.
Results : The severity of SUI was correlated with the Oxford scale measures (r =-0.55, p=0.004), PFM motor activity measured by electromyography (r= -0.58, p=0.002), trunk flexors pic torque at 60°/s (r=-0.45, p=0.022) and the agonist/antagonist ratio of the right hip at 60°/s (r=-0.41, p=0.041). Multivariate linear regression analysis showed that the independent factors associated with the severity of SUI were PFM strength (β=-0.73, p <0,001), trunk flexors pic torque at 60°/s (β=-0.73, p=0.013), right hip flexors pic torque at 60°/s (β=-0.22, p=0.033) and the ratio of trunk flexors pic torque 60°/s on the women weight (β=0.95, p=0.004).
Discussion - Conclusion : We found that incontinent women with greater pelvic floor, abdominal and hip flexor muscles strength had a less severe SUI. Anatomical connections and co-activation between these muscles can explain our findings.
