A corrigendum on
Smoothness metrics in complex movement tasks

by Gulde, P., and Hermsdörfer, J. (2018). Front. Neurol. 9:615. doi: 10.3389/fneur.2018.00615

In the published article, there was an error. In the formula for the log dimensionless jerk, a ³ (to the power of three) was missing.

A correction has been made to the Methods section, fourth formula. This formula previously stated:

\begin{array}{l} log dim . jerk ≜ - l n (\frac{(t^{2} - t^{1})}{v_{p e a k}^{2}} \int_{t_{1}}^{t_{2}} | \frac{d^{2} v}{d t^{2}} |^{2} d t) \end{array}

The corrected formula appears below:

\begin{array}{l} log dim . jerk ≜ - ln (\frac{{(t_{2} - t_{1})}^{3}}{v_{p e a k}^{2}} \int_{t_{1}}^{t_{2}} | \frac{d^{2} v}{d t^{2}} |^{2} d t) \end{array}

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
