Abstract:   (1216 Views)
Uncontrolled Manifold (UCM) approach has gained a lot of attention in the field of movement variability and related areas of research. The diversity of applications and the need to explore new UCM-based measures along with the advances in mathematical methods in UCM have led to several formulas for UCM outcome measures with different notations and conflicting interpretations. This letter is intended to summarize the most popular indexes while suggesting a unified notation.
