METHODS

NIRS was recorded using wavelengths of 760, 850 and 830 nanometers. Data was held internally in a NIRS wireless instrument (Artinis Medical Systems©) and broadcast on demand to a remote computer. NIRS was recorded during natural filling and reflex voiding as well as during multichannel urodynamics with EMG using a water filling at a rate of 50cc. NIRS data (O2Hb, HHb & tHb) were collected at 10 Hz and graphs of patterns of change compared using spatial resolution. Artinis statistical software© calculated continuous TSI in all cases.

RESULTS

12 male spinal cord injured (5 ASIA complete and 7 incomplete) T12 or higher, 2 cases of spina bifeda and 3 non neurogenic controls participated. Chromophore tracings were successfully stored in the wireless device and then transmitted in every trial without loss of data allowing a calculated TSI in each case. A wireless tracing in a male neurogenic …
