Back-to-Normal Walking Speed and Balance a Possibility Post-Stroke Using
  Robotic Device
From: PT Products - 08/03/2017

Depending on the severity of their stroke, patients undergoing ankle training
using a robotic therapy device to aid in their rehabilitation have the
potential for their walking speed and balance to return to normal, according
to a recent study.

"The use of robotic assisted-devices can enhance the therapy by increasing
the intensity of the motor experience. This interactive robotic device moves
the paralyzed arm or leg when the patient cannot and gets out of the way when
the patient powers the movement. In our study, the baseline or initial
walking speed prior to therapy was an important factor in predicting the
final walking speed", says Johanna L. Chang, the study's lead author.
