The timer-logger-communicator gait monitor: Recording temporal gait parameters using a portable computerized device

A portable microprocessor-based device, the timer-logger-communicator (TLC), was adapted and connected to footswitches to monitor and record temporal gait parameters in 25 hemiplegic and 30 normal subjects. Controls walked at 1.36 m/s with symmetric gait. Hemiplegic subjects had a mean walking speed of 0.43 m/s, asymmetric gait, and varying proportions of time spent in each phase, consistent with previously reported gait parameters. Trends in objective gait measures more closely paralleled trends in functional ambulation classification than in Brunnstrom motor recovery stages. The TLC gait monitor is a useful instrument to measure temporal parameters of gait in the clinical setting.
