ASIA impairment score is recorded in the standard A through E format. All subjects had upper motor neuron spinal cord injuries. Bladder management strategies include Foley catheterization (FC), diaper (D), intermittent catheterization (IC), and volitional voiding (VV). Subjects 5 and 7 did not receive a diagnosis of neurogenic detrusor overactivity based on urodynamic measurements.
