"Postural strategies assessed with inertial sensors in healthy and Parkinson subjects" by C. Baston et al. [Gait Posture 40 (2014) 70-75]: Really a new method to analyze postural strategy?

We read with great interest the article by Baston et al. [1] published in Gait & Posture entitled ‘‘Postural strategies assessed with inertial sensors in healthy and Parkinsonian subjects’’. The article describes a novel instrumental method that records the movement of inertial sensors positioned on the legs and trunk, thereby providing analysis of the postural strategy (ankle or hip strategy) adopted to maintain balance during quiet and perturbed stance.
