Challenging human locomotion

Santuz, Alessandro; Ekizos, Antonis; Eckardt, Nils; Kibele, Armin; Arampatzis, Adamantios

The need to move over uneven terrain is a daily challenge. In order to face unexpected perturbations due to changes in the morphology of the terrain, the central nervous system must flexibly modify its control strategies. ...

Dynamic stability control and human energetics

Ekizos, Antonis

Die Bewegungs-kontrollstrategien kontextabhängig und abhängig von unterschiedlichen Kriterien ausgewählt werden. Einerseits ist die Stabilität in den Bewegungszuständen wie der Fortbewegung ausschlaggebend für die ungestörte ...

Fuzziness of muscle synergies in patients with multiple sclerosis indicates increased robustness of motor control during walking

Janshen, Lars; Santuz, Alessandro; Ekizos, Antonis; Arampatzis, Adamantios

Deficits during gait poses a significant threat to the quality of life in patients with Multiple Sclerosis (MS). Using the muscle synergy concept, we investigated the modular organization of the neuromuscular control during ...

Lower complexity of motor primitives ensures robust control of high-speed human locomotion

Santuz, Alessandro; Ekizos, Antonis; Kunimasa, Yoko; Kijima, Kota; Ishikawa, Masaki; Arampatzis, Adamantios

Walking and running are mechanically and energetically different locomotion modes. For selecting one or another, speed is a parameter of paramount importance. Yet, both are likely controlled by similar low-dimensional ...

Modular Control of Human Movement During Running: An Open Access Data Set

Santuz, Alessandro; Ekizos, Antonis; Janshen, Lars; Mersmann, Falk; Bohm, Sebastian; Baltzopoulos, Vasilios; Arampatzis, Adamantios

The human body is an outstandingly complex machine including around 1000 muscles and joints acting synergistically. Yet, the coordination of the enormous amount of degrees of freedom needed for movement is mastered by our ...

Muscle Activation Patterns Are More Constrained and Regular in Treadmill Than in Overground Human Locomotion

Mileti, Ilaria; Serra, Aurora; Wolf, Nerses; Munoz-Martel, Victor; Ekizos, Antonis; Palermo, Eduardo; Arampatzis, Adamantios; Santuz, Alessandro

The use of motorized treadmills as convenient tools for the study of locomotion has been in vogue for many decades. However, despite the widespread presence of these devices in many scientific and clinical environments, a ...

Neuromuscular organisation and robustness of postural control in the presence of perturbations

Munoz-Martel, Victor; Santuz, Alessandro; Ekizos, Antonis; Arampatzis, Adamantios

Perturbation-based exercise interventions challenge balance and improve reactive motor control. Our purpose was to investigate the modular organisation during a standing balance task in both stable and unstable conditions ...

Runners Employ Different Strategies to Cope With Increased Speeds Based on Their Initial Strike Patterns

Ekizos, Antonis; Santuz, Alessandro; Arampatzis, Adamantios

In this paper we examined how runners with different initial foot strike pattern (FSP) develop their pattern over increasing speeds. The foot strike index (FSI) of 47 runners [66% initially rearfoot strikers (RFS)] was ...

The Influence of Footwear on the Modular Organization of Running

Santuz, Alessandro; Ekizos, Antonis; Janshen, Lars; Baltzopoulos, Vasilios; Arampatzis, Adamantios

For most of our history, we predominantly ran barefoot or in minimalist shoes. The advent of modern footwear, however, might have introduced alterations in the motor control of running. The present study investigated shod ...

The Maximum Lyapunov Exponent During Walking and Running: Reliability Assessment of Different Marker-Sets

Ekizos, Antonis; Santuz, Alessandro; Schroll, Arno; Arampatzis, Adamantios

The maximum Lyapunov exponent (MLE) has often been suggested as the prominent measure for evaluation of dynamic stability of locomotion in pathological and healthy population. Although the popularity of the MLE has increased ...
