AB  - Gait and balance disorders are among the most common causes of falls in older 
      adults. Most falls occur as a result of unexpected hazards while walking. In 
      order to improve the effectiveness of current fall-prevention programs, new 
      balance training paradigms aim to strengthen the control of the compensatory 
      responses required after external perturbations. The aim of this study was to 
      analyze the adaptions of reactive and proactive strategies to control stability 
      after repeated exposures to waist-pull perturbations delivered while walking. 
      Eight healthy young subjects participated in a single training session with the 
      Active Tethered Pelvic assisted Device (A-TPAD). Participants were exposed to 
      repeated multi-directional perturbations of increasing intensity. The 
      Antero-Posterior (AP) and Medio-Lateral (ML) Base of Support (BoS) and Margin of 
      Stability (MoS) during the response to diagonal perturbations were compared 
      before and after the training. Results showed that participants adapted both the 
      reactive and proactive strategies to control walking balance by significantly 
      increasing their pre- and post-perturbation stability. The changes were 
      principally accounted for by an increment of the AP BoS and MoS and a reduction 
      of ML BoS. This improved their ability to react to a diagonal perturbation. We 
      envision that this system can be used to develop a perturbation-based gait 
      training aimed at improving balance and control of stability during walking, thus 
      reducing fall risk.
