Fig 2 The change percentages of 3 video-urodynamic (VUD) parameters. The medians were (1) summated electromyographic activity (sEMG): 33% decrement for time 1 (t1) and 35% decrement for time 2 (t2); (2) urethral pressure (PUre): 8% decrement for time 1 and 9% decrement for time 2; and (3) detrusor pressure (PDet): 9% increment for time 1 and 1% decrement for time 2. *Significant change versus baseline value.

Fig 3 Urodynamic graphs of one of the SCI patients. The initial fluctuation of these 3 parameters was induced by placement of anal dilator (point X). We waited for 30 seconds until these parameters stabilized, and the values of the last 15 seconds were collected for baseline value (b). Then, the anus was stretched for an additional 30 seconds (from point Y to point Z). This duration of stretching was further divided into first half (t1) and second half (t2). Abbreviations: sEMG, summated electromyography; PDet, detrusor pressure; PUre, urethral pressure.

Fig 4 The change in percentages of summated electromyographic (sEMG) activity (during time 1) in patients for different AIS grades. The medians of change percentages were 52.4%, 40.5%, 0.3%, and 4% decrement in groups with AIS grades A, B, C, and D, respectively. *Significant change versus baseline (P<.05).
