Changes in predictive motor control in drop-jumps based on uncertainties in task execution

Leukel, Christian ; Taube, Wolfgang ; Lorch, Michael ; Gollhofer, Albert

In: Human Movement Science, 2011, p. -

Drop-jumps are controlled by predictive and reactive motor strategies which differ with respect to the utilization of sensory feedback. With reaction, sensory feedback is integrated while performing the task. With prediction, sensory information may be used prior to movement onset. Certainty about upcoming events is important for prediction. The present study aimed at investigating how...

Non-physical practice improves task performance in an unstable, perturbed environment: motor imagery and observational balance training

Taube, Wolfgang ; Lorch, Michael ; Zeiter, Sibylle ; Keller, Martin

In: Frontiers in Human Neuroscience, 2014, vol. 8, p. 972

For consciously performed motor tasks executed in a defined and constant way, both motor imagery (MI) and action observation (AO) have been shown to promote motor learning. It is not known whether these forms of non-physical training also improve motor actions when these actions have to be variably applied in an unstable and unpredictable environment. The present study therefore investigated the...
