AB  - The objective of the current study was to evaluate the effect of walkway 
      perturbation training on human dynamic walking stability and slip propensity. A 
      new walkway perturbation training program was developed using an instrumented, 
      split-belt treadmill. Walkway surface perturbation was composed of multiple, 
      randomized perturbation pulses. Each pulse was created by sudden accelerating the 
      treadmill belt underneath the dominant foot briefly. Five healthy older adults 
      were involved in a laboratory study. An inertial measurement unit was attached to 
      the subject's low back region to record 3D acceleration. Maximum Lyapunov 
      exponent (maxLE) and transitional acceleration of whole body center of mass 
      (TA_COM) were computed to quantify the local dynamic stability and slip 
      propensity, respectively. The results indicated a significant training effect on 
      both maxLE and TA_COM. It was concluded that the walkway perturbation training 
      program significantly improved local dynamic stability and reduced slip 
      propensity.
