“…Indeed, the vestibular contribution to gait variability, which is a predictive marker for falls, declines with faster walking and running (41). Therefore, their balance would be better when running because dynamic balance strategies are different at low and high speeds (41)(42)(43)(44)(45).…”

“…Studies on the reliability of muscle synergy extraction in relation to sport activities are scarce but nevertheless present in the considered literature [ 108 , 116 , 127 , 128 ]. The most common family of algorithms used to reduce the dimensionality of the data was NMF [ 107 , 108 , 110 114 , 116 125 , 127 133 , 135 137 ], with a few studies also using PCA to extract synergistic muscle activations [ 75 , 109 , 126 , 134 ]. The total number of muscle activities recorded varied heavily across the considered studies.…”

“…The total number of muscle activities recorded varied heavily across the considered studies. We found a range in the number of muscles recorded across these studies, including one to eight [ 108 , 109 , 124 , 126 , 131 , 133 ], between nine and 16 [ 75 , 107 , 110 114 , 116 , 119 , 121 123 , 125 , 128 , 130 , 132 , 134 – 137 ], and between 16 and 25 muscles [ 117 , 118 , 120 , 127 , 129 ]. Bilateral recordings were less common [ 107 , 108 , 117 , 119 , 129 ] than ipsilateral [75, 109-114, 116, 118, 120–128, , 128, 130–137].…”

“…For example, visual inputs are used in the process of planning locomotion to create a model of the environment in which the walking would occur, while proprioception is essential during the execution of the movement to update the feedforwards commands derived from the visual inputs (Bard et al, 1995;Sainburg et al, 1995). Regarding body-based cues, it seems that during walking, vestibular signals are downregulated (Brandt et al, 1999;Pfaff, 2013;Fabre-Adinolfi et al, 2018), whereas proprioception dominates the pattern of muscle activation (Science and 1985). Overall, neural networks controlling posture and gait are highly dependent on vestibular inputs during slow gait and shift their dependency towards proprioception with increased gait speed.…”
