Filter by:The primary goal of this research was to assess the practicality and initial effectiveness of a motor imagery (MI) intervention combined with elements of action observation (AO), alongside active or sham transcranial direct current stimulation (tDCS) over the prefrontal cortex (PFC), on locomotor learning in healthy adults. Feasibility was determined by examining recruitment rates, participant engagement, and safety measures. The efficacy of the intervention was gauged by analyzing the time taken to complete tasks and changes in cerebral blood flow immediately after the intervention and one week later. The study was guided by three main hypotheses: (1) the intervention techniques would be well-received and safe for the participants; (2) compared to a control group, MI training would lead to better learning outcomes and retention of learning; (3) in comparison to the control and sham tDCS groups, active tDCS would result in superior learning outcomes and retention of learning.
The purpose of this study is to compare the effectiveness of different repetitive Transcranial Magnetic Stimulation protocols for enhancing motor learning in healthy peolple.
The purpose of this study is to test if priming expectations of transcranial Direct Current Stimulation (tDCS) can improve the efficacy of tDCS in enhancing motor learning.
Motor learning is crucial for human daily routine, involving the acquisition of new movements. It consists of an online acquisition phase followed by offline consolidation, where motor memory is organized into stable representations. Acquisition can be achieved through physical practice (PP, overt repetition of movement) or mental rehearsal using motor imagery (MI). Recent studies suggest that high-intensity interval physical exercise (HIIE) enhances motor learning, particularly during consolidation, by promoting neural plasticity mediated by brain-derived neurotrophic factor (BDNF). However, the impact of HIIE on sequential motor consolidation with PP or MI remains poorly understood. In contrast, sleep deprivation (SD) reduces BDNF release and neural plasticity. Limited research has explored the effects of SD on motor acquisition, especially sequential motor learning. Considering the opposing effects of HIIE and SD, performing HIIE after SD may protect motor consolidation processes. This study aims to examine the influence of HIIE on sequential motor learning using PP or MI under both sleep-deprived and normal sleep conditions. Six groups, each comprising 12 participants, will learn an 8-item bimanual sequence. - MI group: acquired the motor sequence mentally during training - MI+HIIE group: acquired the motor sequence mentally and achieve a HIIE before the consolidation - PP: acquired the motor sequence physically - PP+HIIE group: acquired the motor sequence physically and achieve a HIIE before the consolidation - SD+PP group: one night of sleep deprivation prior physical motor acquisition with PP and consolidation - SD+PP+HIIE group: one night of sleep deprivation prior physical motor acquisition and HIIE before consolidation. All groups will be tested on the sequence at the beginning and the end of the acquisition phase (pre- and post-acquisition), and after the physical exercise (i.e. HIIE) or the rest period (post-exercise). Hypothesis of this study are : - Acute physical exercise (HIIE) would enhance the consolidation of motor memory (post-exercise) after physical and mental acquisition (PP,MI) compared to conditions without exercise. - One night of sleep deprivation would affect the acquisition and consolidation of motor learning. Physical exercise would compensate for the detrimental effects of sleep deprivation on the consolidation of motor learning.
The purpose of this study is to know the efficacy about the application of repetitive transcranial magnetic stimulation (rTMS) on the somatosensory cortex (S1) to enhance motor function in people with stroke.
The investigators study aimed to observe the effect of motor learning-based tele-rehabilitation on quality of life in children with cerebral palsy during the Covid-19 pandemic.
The general purpose of this research project is to analyze the specific role of motor imagery on motor learning, assessed through corticospinal excitability measurements and behavioral data collection. This project is based on four sequences. For Sequence 1, the main objective is to examine the effect of mental training on movement speed and accuracy in a manual motor sequence task, as well as the influence of sensory feedback in immediate post-test (i.e., execution of a similar, but not identical, manual motor sequence, other manual tasks) on performance in delayed post-test. The secondary objective will be to examine corticospinal changes (i.e., amplitude of motor evoked potentials) induced by mental training, by measuring the amplitude of motor evoked potentials before and after mental training. For Sequence 2, the main objective is to examine the impact of a motor disturbance induced by a robotic arm at different intervals during the motor imagery process. The secondary objective will be to examine the corticospinal changes (i.e. amplitude of evoked motor potentials) induced by mental training as a function of the applied perturbations, before and after perturbation. For Sequence 3, the main objective will be to examine the influence of neuroplasticity on the quality of mental training. More specifically, the investigators will study the links between brain plasticity and motor learning through mental training. The secondary objective will be to examine the corticospinal changes (i.e. amplitude of evoked motor potentials) induced by mental training at different levels of the neuromuscular system (cortical, cervicomedullar, peripheral) after a training period. For Sequence 4, the main objective will be to examine the effect of short-term arm-immobilization of on the retention of motor learning induced by mental training. The secondary objective will be to examine the corticospinal changes (i.e., amplitude of motor evoked potentials) induced by of short-term arm-immobilization, or by transcranial direct current stimulation (tDCS), on motor learning. The results of this fundamental research project will allow a better understanding of neurophysiological and behavioral mechanisms that underlie motor learning through motor imagery. The results will allow to efficiently consider inter-individual specificities and will thus open up to clinical research perspectives, towards the establishment of adapted motor rehabilitation protocols.
30 healthy older participants were enrolled in the study and were randomly classified into two groups. In the experimental group (n = 15) participants received 10-week Tai Chi Chuan practice intervention, in the control group (n=15) participants were asked do not change their living habits in 10 weeks. All participants had no practice Tai Chi Chuan before.
