Spatial constraints and cognitive fatigue affect motor imagery of walking in people with multiple sclerosis

Abstract Motor imagery (MI) is the mental simulation of an action without any overt motor execution. Interestingly, a temporal coupling between durations of real and imagined movements, i.e., the so-called isochrony principle, has been demonstrated in healthy adults. On the contrary, anisochrony has...
