“…Alternatively, the present study provides the first behavioural evidence showing combined AO+MI instructions can be more beneficial than MI alone for impacting movement skills in DCD children. This supports recommendations from recent neurophysiological studies (e.g., Eaves et al, 2016b;Taube et al, 2015), calling for new approaches to training and rehabilitation to involve combined AO+MI instructions (see Eaves et al, 2016a;Emerson et al, 2018;Vogt et al, 2013).…”

Developmental coordination disorder (DCD) is a neurodevelopmental disorder characterised by uncoordinated movement relative to age. While action observation (AO) and motor imagery (MI) can both independently enhance movement skills in children, we report the first study to assess the effects of combined action observation and motor imagery (AO+MI) on automatic imitation in children aged 7-12 years, both with (n = 12) and without DCD (n = 12). On each trial participants planned to execute an instructed rhythmical action (face washing or paint brushing). Before responding, participants observed a rhythmical distractor showing the same or different action, with a subtle speed manipulation across trials (fast vs slow). Automatic imitation was quantified as an imitation bias in subsequent response cycle times. Across blocks of trials participants engaged in AO, MI, or combined AO+MI during the distractor phase, or intentionally imitated the distractor speeds. While there were no between-group differences, combined AO+MI instructions produced a significantly greater imitation bias (115%) than both AO (109%) and MI (109%), with intentional imitation yielding the strongest effects overall (128%). Within-subjects analyses revealed a significant bias for AO and MI in both groups.Combined AO+MI effects were significantly greater than AO in typically developing children, and greater than both AO and MI in DCD children. These results demonstrate a clear capacity for different forms of motor simulation in children both with and without DCD. Moreover, combined AO+MI instructions represent an advantageous method for training movements in children with different motor abilities, compared to separate AO and MI.

“…Thus, the movements of the paralyzed arm and the timing of its movements are important determinants of activation of the sensorimotor cortex. Additionally, MT produces rehabilitation effects through action observation (AO) and motor imagery (MI) [56,57]. Action execution (AE) also plays an important role compared with AO [38,58].…”

Robotic mirror therapy (MT), which allows movement of the affected limb, is proposed as a more effective method than conventional MT (CMT). To improve the rehabilitation effectiveness of post-stroke patients, we developed a sensory stimulation-based continuous passive motion (CPM)-MT system with two different operating protocols, that is, asynchronous and synchronous modes. To evaluate their effectiveness, we measured brain activation through relative and absolute power spectral density (PSD) changes of electroencephalogram (EEG) mu rhythm in three cases with CMT and CPM-MT with asynchronous and synchronous modes. We also monitored changes in muscle fatigue, which is one of the negative effects of the CPM device, based on median power frequency (MPF) and root mean square (RMS). Relative PSD was most suppressed when subjects used the CPM-MT system under synchronous control: 22.11%, 15.31%, and 16.48% on Cz, C3, and C4, respectively. The absolute average changes in MPF and RMS were 1.59% and 9.78%, respectively, with CPM-MT. Synchronous mode CPM-MT is the most effective method for brain activation, and muscle fatigue caused by the CPM-MT system was negligible. This study suggests the more effective combination rehabilitation system for MT by utilizing CPM and magnetic-based MT task to add action execution and sensory stimulation compared with CMT. method uses voluntary exercise to improve a patient's motivation to rehabilitate [4] and prevents the deterioration of the motor ability of the lesioned brain hemisphere using a visual illusion that bilateral movement has been accomplished [5,6]. However, a major drawback of conventional MT (CMT) is that the paralyzed arm does not move at all during the treatment. Thus, muscle atrophy can be aggravated and the elbow can become stiff. Spasticity and hypertonus are likely to limit the functional use of the paralyzed limb. Additionally, muscle hyperexcitability may lead to secondary complications including contracture, pain, and reduced range of motion. In the long term, these complications may also result in structural changes in connective tissues and muscle fibers [7,8]. In such situations, patients lose their motivation to rehabilitate. In addition, the prevalence of strokes increases in an aging society, and the public healthcare burden of patients who have suffered a stroke increases. The current emphasis on cost reduction in medical services has resulted in reducing the duration of in-patient rehabilitation of post-stroke patients. This results in patients terminating treatment with incomplete recovery. These situations have triggered research on better and cost-efficient methods of treatment for post-stroke patients.To overcome the current limitations of CMT methods, a robotic system that actually moves the affected limb has recently been proposed as an emerging rehabilitative method [9,10]. However, building a new system for only one rehabilitation method, like MT, is difficult to introduce in many hospitals owing to budget and utilization issues. In addition, intro...

“…Furthermore, some dancers will dance with their eyes closed, a method that enhances one’s focus on the proprioceptive cues and integration of body awareness. Such strategies of motor learning have also shown some promise in neurorehabilitation for conditions such as Parkinson’s disease ( Caligiore et al, 2017 ), post stroke ( Emerson et al, 2018 ), and are gaining momentum in people with persistent pain ( Thieme et al, 2016 ; Wallwork et al, 2016 ; Suso-Martí et al, 2020 ) to reduce movement-related disability.…”

Multimodal Sensory-Spatial Integration and Retrieval of Trained Motor Patterns for Body Coordination in Musicians and Dancers

Dancers and musicians are experts in spatial and temporal processing, which allows them to coordinate movement with music. This high-level processing has been associated with structural and functional adaptation of the brain for high performance sensorimotor integration. For these integration processes, adaptation does not only take place in primary and secondary sensory and motor areas but also in tertiary brain areas, such as the lateral prefrontal cortex (lPFC) and the intraparietal sulcus (IPS), providing vital resources for highly specialized performance. Here, we review evidence for the role of these brain areas in multimodal training protocols and integrate these findings into a new model of sensorimotor processing in complex motor learning.
