The effects of hand dominance, fatigue, and sex on muscle activation during a repetitive overhead fatiguing task
Hum Mov Sci. 2023 Sep 21;92:103149. doi: 10.1016/j.humov.2023.103149. Online ahead of print.ABSTRACTPrevious studies have shown that the dominant arm is generally stronger and more resistant to fatigue. However, whether there are side differences in shoulder muscle activation during a fatiguing upper limb task, and whether this varies according to sex, is unknown. Thirty right-handed adults (15 females) were recruited to complete two sessions of an overhead repetitive fatiguing task (shoulder flexion between 90 and 135° at 1 Hz), performed in two separate sessions with their dominant arm (DA) and non-dominant arm (NDA) un...

Phasic and tonic muscle synergies are different in number, structure and sparseness
This study aims at testing whether phasic and tonic components are generated by distinct phasic and tonic synergies or by the same set of synergies with phasic and tonic activation coefficients. The study also aims at characterizing the differences between the phasic and the tonic synergies. Using a comprehensive mapping of upper-limb point-to-point movements, synergies were extracted from phasic and tonic EMG signal separately, estimating the tonic components with a linear ramp model. The goodness of reconstruction (R2) as a function of the number of synergies was compared, and sets of synergies extracted from each datase...

Granger Geweke Causality reveals information exchange during physical  interaction is modulated by task difficulty
Hum Mov Sci. 2023 Sep 11;92:103139. doi: 10.1016/j.humov.2023.103139. Online ahead of print.ABSTRACTThe haptic sense is an important mode of communication during physical interactions, and it is known to enable humans to estimate key features of their partner's behavior. It is proposed that such estimations are based upon the exchange of information mediated by the interaction forces, resulting in role distribution and coordination between partners. In the present study, we examined whether the information exchange is functionally modified to adapt to the task, or whether it is a fixed process, leaving the adaptation to in...

Cyclic relationship of mechanical likelihood: Coupling perception-action states in extended haptic accuracy
Hum Mov Sci. 2023 Sep 10;92:103140. doi: 10.1016/j.humov.2023.103140. Online ahead of print.ABSTRACTThe present study investigates the dynamic nature of haptic accuracy in racket sports, specifically focusing on self-produced movements in participants with different skill levels (novice vs. expert). The study examines performance accuracy using indicators such as absolute error size and the coefficient of restitution as measures of haptic accuracy. To collect and analyze the data, custom-made devices, including shock and vibration sensors and Qualisys Track Manager, were used. The results indicate that skilled participants...
