Kinematics and Kinetics of Gait Perturbations in Young Healthy Adults

Study Overview
=================
Brief Summary
-----------------
Investigators would like to examine, what are strategies for balance recovery in gait perturbations. Different perturbation types where used in the current study. The study involves the analysis of kinematic and kinetic parameters. Researchers hypothesize that research including young healthy adults would help to elaborate fall prevention program for seniors.
