“…Compared to isolated upper limb tasks often used to investigate motor sequence learning, whole-body movements pose additional task demands such as interlimb coordination and postural control. Previous studies have adapted the serial reaction time task to be performed by stepping on floor targets in a sequential pattern 34 , 35 , which requires continuous changes in postural dynamics. It was found that increases in resting-state functional connectivity between the lateral prefrontal cortex and associative striatum were correlated with sequence-specific improvements during the acquisition of complex lower-body movements 34 .…”

“…It was found that increases in resting-state functional connectivity between the lateral prefrontal cortex and associative striatum were correlated with sequence-specific improvements during the acquisition of complex lower-body movements 34 . Furthermore, motor imagery practice (without physical practice) can improve performance in the sequential footstep task 35 , reflecting goal-based learning. These studies have thus far suggested that perceptual and motor mechanisms support learning across simple single-body part and more complex lower-body motor tasks.…”

Practicing complex locomotor skills, such as those involving a step sequence engages distinct perceptual and motor mechanisms that support the recall of learning under new conditions (i.e., skill transfer). While sleep has been shown to enhance learning of sequences of fine movements (i.e., sleep-dependent consolidation), here we examined whether this benefit extends to learning of a locomotor pattern. Specifically, we tested the perceptual and motor learning of a locomotor sequence following sleep compared to wake. We hypothesized that post-practice sleep would increase locomotor sequence learning in the perceptual, but not in the motor domain. In this study, healthy young adult participants (n = 48; 18–33 years) practiced a step length sequence on a treadmill cued by visual stimuli displayed on a screen during training. Participants were then tested in a perceptual condition (backward walking with the same visual stimuli), or a motor condition (forward walking but with an inverted screen). Skill was assessed immediately, and again after a 12-h delay following overnight sleep or daytime wake (n = 12 for each interval/condition). Off-line learning improved following sleep compared to wake, but only for the perceptual condition. Our results suggest that perceptual and motor sequence learning are processed separately after locomotor training, and further points to a benefit of sleep that is rooted in the perceptual as opposed to the motor aspects of motor learning.

“…Sleep-dependent performance gains during consolidation would thus depend on task demand (Debarnot et al, 2012), especially in the older population for whom gross motor tasks seem consolidated -after PP -by sleep compared to fine motor tasks (Gudberg et al, 2015). We recently showed sleep-dependent performance gains in young adults, after one session of MIP of a gross motor sequential task involving the whole body (Debarnot et al, 2022). With the age-related alterations in balance, locomotion and sleep, it would be particularly interesting to investigate whether MIP would elicit offline gains in older people in gross motor tasks.…”

BackgroundMotor imagery practice (MIP) and anodal transcranial direct current stimulation (a-tDCS) are innovative methods with independent positive influence on motor sequence learning (MSL) in older adults.ObjectiveThe present study investigated the effect of MIP combined with a-tDCS over the primary motor cortex (M1) on the learning of a finger tapping sequence of the non-dominant hand in healthy older adults.MethodsThirty participants participated in this double-blind sham-controlled study. They performed three MIP sessions, one session per day over three consecutive days and a retention test 1 week after the last training session. During training / MIP, participants had to mentally rehearse an 8-element finger tapping sequence with their left hand, concomitantly to either real (a-tDCS group) or sham stimulation (sham-tDCS group). Before and after MIP, as well as during the retention test, participants had to physically perform the same sequence as fast and accurately as possible.ResultsOur main results showed that both groups (i) improved their performance during the first two training sessions, reflecting acquisition/on-line performance gains, (ii) stabilized their performance from one training day to another, reflecting off-line consolidation; as well as after 7 days without practice, reflecting retention, (iii) for all stages of MSL, there was no significant difference between the sham-tDCS and a-tDCS groups.ConclusionThis study highlights the usefulness of MIP in motor sequence learning for older adults. However, 1.5 mA a-tDCS did not enhance the beneficial effects of MIP, which adds to the inconsistency of results found in tDCS studies. Future work is needed to further explore the best conditions of use of tDCS to improve motor sequence learning with MIP.
