The use of the neurologic exam to predict awareness and control of lower urinary tract function post SCI

Academic Article


  • Study Design:Cross-sectional study.Objectives:To assess whether T11-L2 sensation is significantly associated with perception of bladder filling and whether S3-S5 sensation is significantly associated with potential for voluntary voiding after spinal cord injury (SCI).Setting:Alabama, United States.Methods:A total of 79 men and women with SCI, and 40 able-bodied (AB) subjects, ages 19-60, seen in an outpatient academic medical center clinic, underwent International Standards for Neurological Classification of SCI (ISNCSCI) assessment along with urodynamic testing to assess lower urinary tract (LUT) function. X 2 test was performed to compare: (1) bladder sensation across T11-L2 groups classified by total sensory scores and (2) ability to voluntarily void across S3-S5 scores.Results:Persons with greater ability to perceive pinprick and light touch sensation in the T11-L2 dermatomes were more likely to perceive bladder filling both via self-report and by urodynamics. However, persons with greater sensation at T6-T9 and S3-5 also had a greater likelihood of perceiving bladder filling. Subjects with greater preservation of sensation in S3-5 reported greater ability to initiate and control voiding.Conclusion:Findings suggest ISNCSCI results along with self-report can be used to predict potential for bladder control.Sponsorship:National Institute of Disability and Rehabilitation Research.
