BMC Sports Sci Med Rehabil 2024; 16:103. [PMID: 38702784 PMCID: PMC11067104 DOI: 10.1186/s13102-024-00891-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 04/25/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND children with Intellectual Disabilities (ID) are less proficient in motor skills compared to normally developing children, which means they need more time for learning skills. In this context, the purpose of this research is to investigate the effect of the Brailletonik physical activity program (BPAM) on the balance and reaction time of children with ID. METHODS The statistical sample is consisted of 30 children aged 8 to 12 (21 boys, 9 girls) with ID with an average age of 9.8 ± 1.39, who were selected through convenience sampling. Participants were divided into two groups of individual BPAM, and pair BPAM. Training sessions were held for 21 sessions (seven weeks) and each session included 30 min of training. To measure static balance and reaction time, Stork Stand test and Simple Reaction Time Software were used respectively. The analysis of covariance (ANCOVA) and Bonferroni's post hoc test were used to analyze the data. Data analysis was performed using SPSS software version 26 at a significance level of p ≤ 0.05. RESULTS The results showed that individual and paired exercise groups had significant progress from pre-test to post-test in both variables of balance and reaction time (p = 0.001). Also, the comparison of the performance of the groups in the post-test showed that the average performance of the paired exercise group was significantly better than the individual exercise group in the balance variable (p = 0.03) and in the reaction time variable (p = 0.01). CONCLUSION Accordingly, it can be concluded that BPAM in paired groups has a greater effect on the balance and reaction time of children with ID.

Hohagen J, Immerz A. Focus of attention in musical learning and music performance: a systematic review and discussion of focus instructions and outcome measures. Front Psychol 2024; 15:1290596. [PMID: 38650905 PMCID: PMC11033434 DOI: 10.3389/fpsyg.2024.1290596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 02/26/2024] [Indexed: 04/25/2024] Open
Abstract
The topic of attentional focus (focus of attention, FOA) in musical learning and performance has recently received increasing interest, as the growing number of empirical studies inspired by the established FOA paradigm in sports by Wulf and colleagues in 1998. The current systematical review aims at collecting, abstracting, and categorizing relevant data to show which kinds of FOA instructions were applied in experimental designs and what kinds of dependent variables were used to measure the effects of FOA instruction on musical performance. The three main inclusion criteria in the selection process were experimental design, detailed descriptions of FOA instructions, and outcome measures (OMs). A systematic search was conducted with a complex search term in four scientific databases in March 2023. For presenting and synthesizing results, we used data collection and an inductive-deductive data categorization. Fifteen studies with a total sample size of 401 participants were included out of 387 records initially identified. We collected 53 different FOA instruction citations from the 15 studies and classified them into 9 FOA subcategories, of which the most applied were bodily focus (21%), sound focus (15%), and visual focus (14%). Selected studies used 63 OMs that were abstracted to 10 different OM categories with expert ratings (27%) and acoustical analysis (22%) as the most applied dependent variables. Data categorization and abstraction of additional study information show multiple combinations of FOA instructions, OMs, participants' instruments and expertise, and musical tasks. Finally, studies show no consistent results of superiority of either external or internal or otherwise different FOA considering positive effects on musical performance. Limitations of the review lie in the small study sample, possible criticism of applied eligibility criteria, and subjectivity of data categorization. We propose a research agenda with a more exploratory approach that comprehensively and qualitatively examines the dimensions of musical goals to create a database that could provide a foundation for developing a music-specific FOA model.

Comparing the Effects of Differential and Visuo-Motor Training on Functional Performance, Biomechanical, and Psychological Factors in Athletes after ACL Reconstruction: A Randomized Controlled Trial. J Clin Med 2023; 12:2845. [PMID: 37109182 PMCID: PMC10142379 DOI: 10.3390/jcm12082845] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 03/28/2023] [Accepted: 04/07/2023] [Indexed: 04/29/2023] Open
Abstract
Variation during practice is widely accepted to be advantageous for motor learning and is, therefore, a valuable strategy to effectively reduce high-risk landing mechanics and prevent primary anterior cruciate ligament (ACL) injury. Few attempts have examined the specific effects of variable training in athletes who have undergone ACL reconstruction. Thereby, it is still unclear to what extent the variations in different sensor areas lead to different effects. Accordingly, we compared the effects of versatile movement variations (DL) with variations of movements with emphasis on disrupting visual information (VMT) in athletes who had undergone ACL reconstruction. Forty-five interceptive sports athletes after ACL reconstruction were randomly allocated to a DL group (n = 15), VT group (n = 15), or control group (n = 15). The primary outcome was functional performance (Triple Hop Test). The secondary outcomes included dynamic balance (Star Excursion Balance Test (SEBT)), biomechanics during single-leg drop-landing task hip flexion (HF), knee flexion (KF), ankle dorsiflexion (AD), knee valgus (KV), and vertical ground reaction force (VGRF), and kinesiophobia (Tampa Scale of Kinesiophobia (TSK)) assessed before and after the 8 weeks of interventions. Data were analyzed by means of 3 × 2 repeated measures ANOVA followed by post hoc comparison (Bonferroni) at the significance level of p ≤ 0.05. Significant group × time interaction effects, main effect of time, and main effect of group were found for the triple hop test and all eight directions, SEBT, HF, KF, AD, KV, VGRF, and TSK. There was no significant main effect of group in the HF and triple hop test. Additionally, significant differences in the triple hop test and the seven directions of SEBT, HF, KF, KV, VGRF, and TSK were found between the control group and the DL and VMT groups. Between group differences in AD and the medial direction of SEBT were not significant. Additionally, there were no significant differences between VMT and the control group in the triple hop test and HF variables. Both motor learning (DL and VMT) programs improved outcomes in patients after ACL reconstruction. The findings suggest that DL and VMT training programs lead to comparable improvements in rehabilitation.

Abstract
Anterior cruciate ligament injury is one of the pathologies that affect the daily and professional life of the majority of athletes. When the treatment options are examined, there are two options surgical treatment and conservative treatment. Rehabilitation is essential in both cases, with or without surgery. Especially for returning to sports, long-term rehabilitation after surgery has become essential. While many different exercise methods have been tried in the prevention of anterior cruciate ligament injury and rehabilitation after reconstructive surgery, many have focused on strength training. The abnormal movement pattern that occurs with the somatosensory loss seen after anterior cruciate ligament injury results in a functional loss in the injured extremity and the contralateral extremity in the long term. Considering the incidence of injury, studies to establish the normal movement pattern and restore motor control are very important. For this reason, motor learning-based interventions that support neuroplasticity are of great interest today. This review aims to examine the functional results of current motor learning-based interventions in anterior cruciate ligament rehabilitation in line with the literature.

The Path to Translating Focus of Attention Research Into Canadian Physiotherapy, Part 1: Physiotherapists’ Self-Reported Focus of Attention Use Via a Study-Specific Questionnaire.

Abstract
The focus of attention literature has shown robust findings for the benefits of providing statements that focus on the movement effect or outcome (external focus of attention [EFOA]) as opposed to focusing on the movement kinematics (internal focus of attention). Observational studies, however, have revealed that physiotherapists use fewer EFOA statements than internal focus of attention statements in their practice. Most evidence in this regard has been from non-Canadian physiotherapists working in stroke rehabilitation; consequently, we sought to examine whether Canadian physiotherapists working with various rehabilitation populations also use EFOA statements to a lesser extent than internal focus of attention statements. The “Therapists’ Perceptions of Motor Learning Principles Questionnaire (TPMLPQ)” was thus designed and data from 121 Canadian physiotherapists showed low relative frequencies of EFOA use (31.3% ± 14%) averaged across six hypothetical scenarios. A higher EFOA was reported, however, for two of the six scenarios: a functional reaching scenario (55.5% ± 37.0%) and pelvic floor task (65.6% ±32.9%). This data suggest that the findings of EFOA benefits have not been widely translated into Canadian physiotherapy settings; furthermore, the findings of the scenario-dependency warrant future investigation into factors, such as task characteristics, that may influence physiotherapists’ FOA use.

Effect of repeated explicit instructions on visuomotor adaptation and intermanual transfer. Exp Brain Res 2022; 240:2953-2963.

Abstract
The aim of the present study was to investigate the effect of repeated explicit instructions on visuomotor adaptation, awareness, and intermanual transfer. In a comprehensive study design, 48 participants performed center-out reaching movements before and during exposure to a 60° rotation of visual feedback. Awareness and intermanual transfer were then determined. Twelve participants each were assigned to one of the following adaptation conditions: gradual adaptation, sudden adaptation without instructions, sudden adaptation with a single instruction before adaptation, and sudden adaptation with multiple instructions before and during adaptation. The explicit instructions explained the nature of the visual feedback perturbation and were given using an illustration of a clock face. Analysis of adaptation indices revealed neither increased nor decreased adaptation after repeated instructions compared with a single instruction. In addition, we found significant group differences for the awareness index, with lower awareness after gradual adaptation than after sudden, instructed adaptation. Our data also show increased initial adaptation in aware participants; regardless of whether awareness was developed independently or with instruction. Intermanual transfer did not differ between groups. However, we found a significant correlation between the awareness and intermanual transfer indices. We conclude that the magnitude of the explicit process cannot be further increased by repeated instruction and that intermanual transfer appears to be largely related to the explicit adaptation process.

Abstract
Ballistic motor training induces plasticity changes and imparts a cross-transfer effect. However, whether there are age-related differences in these changes remain unclear. Thus, the purpose of this study was to perform a meta-analysis to determine the corticospinal responses and cross-transfer of motor performance following ballistic motor training in young and older adults. Meta-analysis was performed using a random-effects model. A best evidence synthesis was performed for variables that had insufficient data for meta-analysis. There was strong evidence to suggest that young participants exhibited greater cross-transfer of ballistic motor performance than their older counterparts. This meta-analysis showed no significant age-related differences in motor-evoked potentials (MEPs), short-interval intracortical inhibition (SICI) and surface electromyography (sEMG) for both hands following ballistic motor training.

Abstract
Movement disorders encompass a variety of conditions affecting the nervous system at multiple levels. The pathologic processes underlying movement disorders alter the normal neural functions and could lead to aberrant neuroplastic changes and to clinical phenomenology that is not expressed only through mere motor symptoms. Given this complexity, the responsiveness to pharmacologic and surgical therapies is often disappointing. Growing evidence supports the efficacy of neurorehabilitation for the treatment of movement disorders. Specific form of training involving both goal-based practice and aerobic training could drive and modulate neuroplasticity in order to restore the circuitries dysfunctions and to achieve behavioral gains. This chapter provides an overview of the alterations expressed in some movement disorders in terms of clinical signs and symptoms and plasticity, and suggests which ones and why tailored rehabilitation strategies should be adopted for the management of the different movement disorders.

Abstract
When learning a new skill through an unknown environment, should we practice alone, or together with another beginner, or learn from the expert? It is normally helpful to have an expert guiding through unknown environmental dynamics. The guidance from the expert is fundamentally based on mutual interactions. From the perspective of the beginner, one needs to face dual unknown dynamics of the environment and motor coordination of the expert. In a cooperative visuo-haptic motor task, we asked novice participants to bring a virtual mass onto the specified target location under an unknown external force field. The task was completed by an individual or with an expert or another novice. In addition to evaluation of the motor performance, we evaluated the adaptability of the novice participants to a new partner while attempting to achieve a common goal together. The experiment was set in five phases; baseline for skill transfer and adaptability, learning and evaluation for adaptability and skill transfer respectively. The performance of the participants was characterized by using the time to target, effort index, and length of the trajectory. Experimental results suggested that (1) peer-to-peer interactions among paired beginners enhanced the motor learning most, (2) individuals practicing on their own (learning as a single) showed better motor learning than practicing under the expert's guidance, and (3) regarding the adaptability, peer-to-peer interactions induced higher adaptability to a new partner than the novice-to-expert interactions while attempting to achieve a common goal together. Thus, we conclude that the peer-to-peer interactions under a collaborative task can realize the best motor learning of the motor skills through the new environmental dynamics, and adaptability to others in order to achieve a goal together. We suggest that the peer-to-peer learning can induce both adaptability to others and learning of motor skills through the unknown environmental dynamics under mutual interactions. On the other hand, during the peer-to-peer interactions, the novice can learn how to coordinate motion with his/her partner (even though one is a new partner), and thus, is able to learn the motor skills through new environmental dynamics.

Abstract
OBJECTIVE While previous studies showed that the single nucleotide polymorphism (Val66Met) of brain-derived neurotrophic factor (BDNF) can impact neuroplasticity, the influence of BDNF genotype on cortical circuitry and relationship to neuroplasticity remain relatively unexplored in human. METHODS Using individualised transcranial magnetic stimulation (TMS) parameters, we explored the influence of the BDNF Val66Met polymorphism on excitatory and inhibitory neural circuitry, its relation to I-wave TMS (ITMS) plasticity and effect on the excitatory/inhibitory (E/I) balance in 18 healthy individuals. RESULTS Excitatory and inhibitory indexes of neurotransmission were reduced in Met allele carriers. An E/I balance was evident, which was influenced by BDNF with higher E/I ratios in Val/Val homozygotes. Both long-term potentiation (LTP-) and depression (LTD-) like ITMS plasticity were greater in Val/Val homozygotes. LTP- but not LTD-like effects were restored in Met allele carriers by increasing stimulus intensity to compensate for reduced excitatory transmission. CONCLUSIONS The influence of BDNF genotype may extend beyond neuroplasticity to neurotransmission. The E/I balance was evident in human motor cortex, modulated by BDNF and measurable using TMS. Given the limited sample, these preliminary findings warrant further investigation. SIGNIFICANCE These novel findings suggest a broader role of BDNF genotype on neurocircuitry in human motor cortex.

Abstract
It is commonly accepted that the brains capacity to change, known as plasticity, declines into old age. Recent studies have used a variety of non-invasive brain stimulation (NIBS) techniques to examine this age-related decline in plasticity in the primary motor cortex (M1), but the effects seem inconsistent and difficult to unravel. The purpose of this review is to provide an update on studies that have used different NIBS techniques to assess M1 plasticity with advancing age and offer some new perspective on NIBS strategies to boost plasticity in the ageing brain. We find that early studies show clear differences in M1 plasticity between young and older adults, but many recent studies with motor training show no decline in use-dependent M1 plasticity with age. For NIBS-induced plasticity in M1, some protocols show more convincing differences with advancing age than others. Therefore, our view from the NIBS literature is that it should not be automatically assumed that M1 plasticity declines with age. Instead, the effects of age are likely to depend on how M1 plasticity is measured, and the characteristics of the elderly population tested. We also suggest that NIBS performed concurrently with motor training is likely to be most effective at producing improvements in M1 plasticity and motor skill learning in older adults. Proposed NIBS techniques for future studies include combining multiple NIBS protocols in a co-stimulation approach, or NIBS strategies to modulate intracortical inhibitory mechanisms, in an effort to more effectively boost M1 plasticity and improve motor skill learning in older adults.

Abstract
Despite the efforts of many traditional lower extremity injury prevention programs (IPP), the incidence of anterior cruciate ligament injuries in young athletes continues to rise. Current best practices for IPPs include training lower extremity neuromuscular control and movement quality during cutting, jumping, and pivoting. Emerging evidence indicates neurocognition may contribute to injury incidence and injury risk biomechanics. Therefore, IPP outcomes may improve if clinicians also consider neurocognitive contributions to neuromuscular control and athletic performance. A substantial barrier to neurocognitive challenge integration during injury prevention training in the group setting is the lack of structured neuromuscular and neurocognitive progressions. Therefore, our aim is to provide clinicians with a defined framework and recommendations from clinical experience for how to implement neurocognitive challenges within group IPPs that requires minimal extra time and resources. This clinical commentary proposes a three-phase model adopted from motor learning literature to simultaneously progress neuromuscular and neurocognitive challenges through a structured IPP.

Abstract
Stroke continues to be a leading cause of disability. Basic neurorehabilitation research is necessary to inform the neuropathophysiology of impaired motor control, and to develop targeted interventions with potential to remediate disability post-stroke. Despite knowledge gained from basic research studies, the effectiveness of research-based interventions for reducing motor impairment has been no greater than standard of practice interventions. In this perspective, we offer suggestions for overcoming translational barriers integral to experimental design, to augment traditional protocols, and re-route the rehabilitation trajectory toward recovery and away from compensation. First, we suggest that researchers consider modifying task practice schedules to focus on key aspects of movement quality, while minimizing the appearance of compensatory behaviors. Second, we suggest that researchers supplement primary outcome measures with secondary measures that capture emerging maladaptive compensations at other segments or joints. Third, we offer suggestions about how to maximize participant engagement, self-direction, and motivation, by embedding the task into a meaningful context, a strategy more likely to enable goal-action coupling, associated with improved neuro-motor control and learning. Finally, we remind the reader that motor impairment post-stroke is a multidimensional problem that involves central and peripheral sensorimotor systems, likely influenced by chronicity of stroke. Thus, stroke chronicity should be given special consideration for both participant recruitment and subsequent data analyses. We hope that future research endeavors will consider these suggestions in the design of the next generation of intervention studies in neurorehabilitation, to improve translation of research advances to improved participation and quality of life for stroke survivors.

Testing a new active learning approach to advance motor learning knowledge and self-efficacy in physical therapy undergraduate education. BMC MEDICAL EDUCATION 2021; 21:62.

Abstract
BACKGROUND Motor learning (ML) science is foundational for physical therapy. However, multiple sources of evidence have indicated a science-practice gap. Clinicians report low self-efficacy with ML concepts and indicate that the lack of access to systematic training is a barrier for practical implementation. The general goal of this preliminary study was to describe the effects of a new educational intervention on physical therapy student's ML self-efficacy and knowledge. METHODS Self-efficacy was assessed with the Physical Therapists' Perceptions of Motor Learning questionnaire. Data was acquired from third-semester students before their participation in the ML educational intervention. Reference self-efficacy data was also acquired from physical therapy professionals and first and last-semester students. The educational intervention for third-semester students was designed around an established framework to apply ML principles to rehabilitation. A direct experience, the "Learning by Doing" approach, in which students had to choose a motor skill to acquire over 10 weeks, provided the opportunity to apply ML theory to practice in a personally meaningful way. After the intervention self-efficacy was re-tested. ML knowledge was tested with an objective final exam. Content analysis of coursework material was used to determine how students comprehended ML theory and related it to their practical experience. The Kruskal-Wallis and Mann-Whitney U tests were used to compare self-efficacy scores between the four groups. Changes in self-efficacy after the educational intervention were analyzed with the Wilcoxon test. Spearman rank correlation analysis was used to test the association between self-efficacy and final exam grades. RESULTS By the end of the intervention, students' self-efficacy had significantly increased (p < 0.03), was higher than that of senior students (p < 0.00) and experienced professionals (p < 0.00) and correlated with performance on an objective knowledge test (p < 0.03). Content analysis revealed that students learned to apply the elements of ML-based interventions present in the scientific literature to a real-life, structured ML program tailored to personal objectives. CONCLUSIONS Positive improvements were observed after the intervention. These results need confirmation with a controlled study. Because self-efficacy mediates the clinical application of knowledge and skills, systematic, active training in ML may help reduce the science-practice gap.

Abstract
Purpose: To provide a review of current articles that have used observation interventions to enhance motor skill acquisition or performance of applied tasks, and to situate the research within the Applied Model for the Use of Observation (AMUO) with the goal of forming a basis for evidence-based guidelines for practitioners. Method: Key words (e.g., observation/modeling) were searched in varied data bases (e.g., Google Scholar/PubMed), along with a citation search of the relevant AMUO article, to generate a pool of articles for possible review. Selection criteria included publication between 2011 and 2018, and that the research focus was on the effects of an observation intervention on the acquisition or performance of an applied motor task. Results: Forty-eight articles were reviewed, with 21 of these targeting the basic question of whether observation is effective, and the remaining pertaining to the What, When, Who, and How features of the AMUO. The effectiveness of observation interventions was not only affirmed, but also extended to a wider scope of populations and settings. Greater insight into the necessary information with respect to the demonstration (what) and whether it should be before, after, or during physical practice (when) was obtained. As well, advantages of combining model types (who) and providing control to the learner (how) were reported. Conclusions: While more clarity was brought to certain features of the AMUO that could be used to provide evidence-based guidelines, more research is needed to fully inform practitioners for the effective use of observation interventions.

Abstract
The present study sought to evaluate how mental effort modulates premotor activity within forearm muscles in the context of an isometric grasping task. Muscle activity of the flexor digitorum superficialis (FDS) and extensor digitorum communis (EDC) was recorded during the application of maximum grip forces in nineteen healthy adult subjects. Each subject was examined under two experimental conditions: 1) spontaneous initiation of grasp (SI) and 2) focused concentration preceding the initiation of grasp (CA). Two novel parameters, the mean premotor duration (MPD) and the mean premotor power (MPP) were used to distinguish patterns of muscle activity. Here we tested the hypothesis was maximal grip strength is primed by muscle activity during the premotor phase. Our results demonstrate that MPD for each muscle group was significantly longer in the CA condition than for the SI condition (BF10 = 491497) and that MPP was significantly greater in EDC than in FDS (BF10 = 4305). Furthermore, both the MPD and MPP of the EDC were significantly correlated with maximum grip force. These results suggest that the increase of premotor activity consequent to the mental effort (focused concentration) may support internal biomechanical and physiological mechanisms which serve to enhance patterns of neuromuscular synergies.

Effects of dual-task demands on the complexity and task performance of submaximal isometric handgrip force control. Eur J Appl Physiol 2020; 120:1251-1261.

Abstract
PURPOSE To determine the effect of cognitive-motor dual-task load on temporal structure irregularity (complexity) of motor output and task performance of submaximal isometric contractions. METHODS Twelve young, sedentary subjects performed handgrip isometric contractions until failure at 50% of maximal voluntary contraction under mathematical self-regulated dual-task (own pace; SDT), regulated dual-task (imposed pace; RDT), and control. Force signal complexity was calculated by sample entropy at the initial, middle, and final thirds. Task performance was assessed by muscle fatigue (time to failure and rate of median frequency of the radial flexor of the carpus), force and math task error, and self-perceived difficulty. RESULTS Only RDT decreased complexity with respect to control (17.4% ± 12.6%, p = 0.005), all conditions decreased complexity by the final third (Control: 52.8% ± 18.7%, p < 0.001; SDT: 41.1% ± 32.1%, p = 0.003; RDT: 19.1% ± 21.9%, p = 0.035). Conditions did not affect time to failure, and only RDT decreased the rate of median frequency (0.1%/s ± 0.1%/s, p = 0.020). Inferior force error rate was increased by conditions (SDT: 1.5% ± 0.8%, p < 0.001; RDT: 2% ± 1.5%, p = 0.002). Math error was only augmented by RDT (from 9.9 ± 6.7 to 51.7 ± 18.8, p < 0.001), categorized as "very hard" in 85.7% of participants (p = 0.015). CONCLUSION Only the RDT condition reduced complexity and neuromuscular fatigue while increasing force error rate of the handgrip's motor output, without affecting time to failure. A highly demanding dual-task may become a strategy to modify the organization of the hand force motor output, which may contribute to its motor adaptations.

Abstract
Parkinson's disease (PD) results in a complex deterioration of motor behavior. Effective pharmacological or surgical treatments addressing the whole spectrum of both motor and cognitive symptoms are lacking. The cumulative functional impairment may have devastating socio-economic consequences on both patients and caregivers. Comprehensive models of care based on multidisciplinary approaches may succeed in better addressing the overall complexity of PD. Neurorehabilitation is a highly promising non-pharmacological intervention for managing PD. The scientific rationale beyond rehabilitation and its practical applicability remain to be established. In the present perspective, we aim to discuss the current evidence supporting integrated motor-cognitive and aerobic rehabilitation approaches for patients with PD while suggesting a practical framework to optimize this intervention in the next future.

Abstract
Allowing learners to control the number of practice trials has been shown to facilitate motor learning (Lessa & Chiviacowsky, 2015; Post et al., 2011; 2014). However, it is uncertain the extent to which prior findings were influenced by the combined effects of allowing participants to control both the pacing- and amount-of-practice. The present study examined the independent effects of self-controlled amount- and pacing-of-practice on learning a sequential timing task. Participants were assigned to a self-controlled-amount-of-practice (SCA), self-controlled-pacing-of-practice (SCP), yoked-amount-of-practice (YKA), or a yoked-pacing-of-practice (YKP) group. Participants completed acquisition, immediate retention/transfer and delayed retention/transfer. During acquisition, SCA controlled the number of acquisition blocks completed with a fixed inter-trial interval while SCP controlled the inter-trial interval with a fixed number of blocks. Yoked groups were matched to a self-control counterpart so the amount (YKA) and pacing (YKP) were equivalent. Self-control groups demonstrated lower absolute constant error during immediate-retention and lower absolute constant error and variable error during delayed retention (p < .05). For intrinsic motivation, SCA scored significantly higher than SCP for the subscale Interest/Enjoyment (p < .05). Findings indicated that self-control, regardless of type, facilitated motor learning. Further work is needed to continue to examine the relationship between controlling the amount and pacing of practice on skill acquisition.

Abstract
BACKGROUND The importance of motor learning knowledge for physical therapist practice is well known; however, its application is lacking. Conceptual frameworks that place motor learning knowledge within a clinical context are a potential mediator to overcome this gap. PURPOSE This study aimed to conduct a scoping review of the literature to identify and describe the content of such conceptual frameworks in physical therapy/rehabilitation, including the approaches taken in their development and the "elements" or building blocks of motor learning-based interventions within each conceptual framework. DATA SOURCES The data sources used were PubMed, CINAHL, and PsychInfo databases. STUDY SELECTION Articles that were selected had a primary focus on motor learning and its application in physical therapy/rehabilitation and were published between 2000 and 2017. DATA EXTRACTION Twelve of 62 relevant articles met the inclusion criteria. DATA SYNTHESIS Papers attempted to translate theoretical knowledge into a coherent, clinically accessible conceptual framework via 3 main approaches: synthesizing selected motor learning elements into original new conceptual frameworks, mapping motor learning elements in current clinical practices, and assembling selected motor learning elements. The elements of motor learning that were common across papers included theoretical concepts (such as "meaningful goal setting" and "active involvement"); practice variables (including the type, frequency, and timing of feedback; the focus of instructions; task breakdown; and the amount, variability, and order of practice); and intervention strategies (task specific and mental practice). Psychological aspects related to self-efficacy and motivation were also considered integral. LIMITATIONS Papers published before the year 2000 were excluded. CONCLUSION The scoping review revealed that the presentation of motor learning elements in a coherent framework encompassed very diverse approaches and used different categorization systems. In addition, to fully grasp the complexity of clinical practice, motor learning should be coupled with other fields of knowledge.

Abstract
BACKGROUND Neurotoxic cancer treatments can cause chemotherapy-induced peripheral neuropathy and postural control deficits that cancer survivors report as a concern. Exercise-based sensorimotor training has emerged as a promising treatment for symptoms including balance deficits, however, more study is needed to optimize engagement and participation. We evaluated feasibility, satisfaction, and preliminary efficacy of a novel balance training program for cancer survivors: partnered, Adapted Argentine Tango dance (Tango). METHODS Twenty-two individuals participated (n = 22). Tango classes (1 h) were offered twice/week. At baseline, midpoint (8 classes), and conclusion of the training (15 or 16 classes), we assessed postural control by measuring center-of-pressure (CoP) measures during quiet standing with eyes closed. We also documented attendance, barriers to attendance, and satisfaction (7 point scale; 1 high). At conclusion, we analyzed whether 1) attendance and satisfaction met feasibility criteria; 2) postural control improved among participants who were outside of normal range at baseline; and 3) co-enrolling with a companion increased attendance. FINDINGS Feasibility criteria were met: more than half of participants attended more than half the classes offered with a mean satisfaction rate of 1.2 (SD 0.4). Those who enrolled with a companion (n = 9) attended more sessions than those who did not (n = 13) (Mann-Whitney U value = 20; p = 0.012). Participants with demonstrated deficits (n = 9) improved in 3 CoP measures at midpoint (i.e., medial-lateral sway, ellipse area, medial-lateral velocity), retaining improvement in 2 CoP measures at endpoint (i.e., medial-lateral sway, ellipse area). INTERPRETATION Partnered, Adapted Argentine Tango is feasible for cancer survivors and may improve postural control. Enrolling with a companion improved attendance.

Abstract
Introduction: The perceptions and beliefs of physical therapists play an important role in their clinical behavior. These clinician-related aspects may contribute to the knowledge-action gap in the field of motor learning (ML). Accordingly, this study explored how a sample of physical therapists perceive ML in their practice.Methods: A qualitative phenomenological study was conducted. Twelve physical therapists with a wide range of work experience were purposefully selected. Data were collected through semi-structured interviews and analyzed using content analysis methodology. Themes and categories were identified.Results: We identified five key themes: 1) 'ML within the scope of PT' showed that participants perceived ML as a fundamental part of the profession; 2) 'Understanding of ML' showed that participants had difficulty understanding the field comprehensively; 3) 'Self-efficacy toward the topic of ML' revealed that participants had low self-efficacy about their knowledge of the topic; 4) 'Features of ML implementation' showed that physical therapists tended to implement ML intuitively; and 5) 'Barriers to implementation and ways to facilitate it' showed that lack of knowledge was perceived as a main barrier to implementation.Conclusions: Physical therapists' perceptions of and experiences with ML showed the complexity of the field and the lack of clarity regarding its theoretical content and clinical applications. There is a need to reinforce knowledge of ML among physical therapists at different levels of professional development and to promote self-efficacy toward its use, possibly by increasing ML knowledge and education while emphasizing its clinical context.

Abstract
The purpose of the experiment was to determine the extent to which observation and the inter-trial dialogue in a dyad training protocol enhance the development of a movement sequence representation. The task was to reproduce a 1300ms spatial-temporal pattern of elbow extension/flexion movements. An inter-manual transfer design with a retention test and two effector transfer tests was used. The mirror transfer test required the same motor pattern of homologous muscle activation and a sequence of joint angles as experienced during the acquisition phase, and the non-mirror transfer test required the same visual-spatial pattern as practiced during acquisition. Participants (N=40) were randomly assigned to one of four groups (50 practice acquisition trials): a dyad training group where two participants alternated between physical and observational practice and permitting an inter-trial dialogue, a dyad training group where two participants alternated between physical practice and permitting a dialogue without observation, a dyad training group where two participants alternated between physical and observational practice without a dialogue, and an individual practice control group where one participant learned the movement sequence. The practice duration was for all participants identical. The results indicated that participants involved in the dyad training protocols with either observation and/or the inter-trial dialogue developed a motor representation of the movement sequence.

Abstract
There is some evidence that alternating physical and observational practice with a partner for the same skill can benefit learning compared to practice alone. What has not been studied is whether a partner's interleaved practice impacts multi-skill learning, when the partner either matches or mismatches their partner's skill. Here we manipulated partners' practice schedules of two golf putting skills. Partners practiced the same ("matched") or different skills in alternation ("mismatched"). Based on previous research where interleaved demonstrations have induced beneficial contextual interference effects, we hypothesized that mismatching a partner on consecutive trials should also promote a similar type of interference in practice, which ultimately aids learning. A third control group was tested, where only one partner practiced while the other observed. All groups practiced for two days, with individual retention tests at the start of day 2 and one week later. Taking turns practicing and observing a partner did not benefit learning compared to the control, pure physical practice group and the matched and mismatched groups did not differ in outcomes. There was, however, evidence that partners were adapting their actions (i.e., compensating for over or undershooting of the target) based on the shots of their partner, in a similar manner to how they were adapting to their own errors. Thus, although partners were influencing each other's performance, it was not ultimately to the benefit (or cost) of overall learning. Partner-mismatching of skills through alternating practice was not sufficient to promote interference in practice and ultimately promote learning.

Abstract
Purpose: This article describes the content of and delivery methods for motor learning (ML) education and the attitudes and beliefs of instructors with regard to how ML is taught in Canadian physical therapy (PT) programmes. Method: A qualitative descriptive design was employed, using an online questionnaire and semi-structured telephone interviews. A descriptive content analysis was used to develop codes and themes. An online search of PT programme Web sites was conducted to supplement missing data and collect information from schools that did not participate in the online questionnaire or interview. Results: Eight individuals representing seven schools completed the questionnaire; six of the eight also completed the interview. Responses conveyed the fact that ML content was fairly consistent across schools and was predominantly situated in the neurological curriculum. Schools differed in the delivery methods used for clinical application of ML content. Respondents believed that ML underlies PT practice and should be integrated throughout the programme. Conclusion: Current instruction may deliver adequate ML content but may not provide optimal opportunities to apply ML principles in a clinical context. Continuing education emerged as one suggestion for remediating clinicians' knowledge-practice gap and facilitating student learning on placement. Only half the eligible PT schools participated, and all were English-language programmes; thus, the findings may not be generalizable to all Canadian programmes. Future work should explore how ML can be integrated into the PT curriculum to promote the application of ML principles across different fields. Students' perspectives on their understanding of ML and ML principles and self-efficacy for entry to practice should also be explored.

Abstract
Parkinson's disease (PD) is characterized by motor and cognitive dysfunctions, affecting the motor behaviour. We summarize evidence that the interplay between motor and cognitive approaches is crucial in PD rehabilitation. Rehabilitation is complementary to pharmacological therapy and effective in reducing the PD disturbances, probably acting by inducing neuroplastic effects. The motor behaviour results from a complex integration between cortical and subcortical areas, underlying the motor, cognitive and motivational aspects of movement. The close interplay amongst these areas makes possible to learn, control and express habitual-automatic actions, which are dysfunctional in PD. The physiopathology of PD could be considered the base for the development of effective rehabilitation treatments. As the volitional action control is spared in early-medium stages of disease, rehabilitative approaches engaging cognition permit to achieve motor benefits and appear to be the most effective for PD. We will point out data supporting the relevance of targeting both motor and cognitive aspects in PD rehabilitation. Finally, we will discuss the role of cognitive engagement in motor rehabilitation for PD.

Abstract
[Purpose] This study was carried out to examine the effect of the application of group
exercise program composed to induce interests and assertive participation of adults with
cerebral palsy on the self-efficacy and activities of daily living, as well as to provide
basic clinical data that are effective and trustworthy in enhancing the physical and
emotional interaction in the future. [Subjects and Methods] Those among the 23 adult with
cerebral palsy who are the subjects of research and able to participate only in the
evaluation of measurement tools prior to and after the experiment were allocated to the
control group while only those who can participate in the group exercise program
implemented over 12 sessions were allocated to the experimental group. For the control
group, a range of motion of joint exercise and stretching exercise were executed on the
arms, legs and trunk, while for the experimental group, group exercise that is implemented
with participation of several subjects simultaneously was executed 2 times a week with 40
minutes for each session over a period of 6 weeks for the total of 12 sessions. [Results]
In both the experimental group and the control group, there were statistically significant
changes in the average scores of self-efficacy and activities of daily living after the
exercise in comparison to that prior to the exercise. Moreover, there were statistically
significant differences in self-efficacy and activities of daily living in terms of
quantity of change prior to and after the exercise between the two groups. [Conclusion]
Therefore, group exercise program composed to induce physical and emotional interaction,
and active participation of adults with cerebral palsy can be considered as an effective
intervention method in improving their self-efficacy and activities of daily living.

Abstract
It is evident that user training significantly affects performance of pattern-recognition-based myoelectric prosthetic device control. Despite plausible classification accuracy on offline datasets, online accuracy usually suffers from the changes in physiological conditions and electrode displacement. The user ability in generating consistent electromyographic (EMG) patterns can be enhanced via proper user training strategies in order to improve online performance. This study proposes a clustering-feedback strategy that provides real-time feedback to users by means of a visualized online EMG signal input as well as the centroids of the training samples, whose dimensionality is reduced to minimal number by dimension reduction. Clustering feedback provides a criterion that guides users to adjust motion gestures and muscle contraction forces intentionally. The experiment results have demonstrated that hand motion recognition accuracy increases steadily along the progress of the clustering-feedback-based user training, while conventional classifier-feedback methods, i.e., label feedback, hardly achieve any improvement. The result concludes that the use of proper classifier feedback can accelerate the process of user training, and implies prosperous future for the amputees with limited or no experience in pattern-recognition-based prosthetic device manipulation.It is evident that user training significantly affects performance of pattern-recognition-based myoelectric prosthetic device control.

Abstract
Introduction: The study sought to examine the performance strategies of wounded, ill, and injured service members and Veterans who participate in the Warrior Games. Methods: The Test of Performance Strategies (TOPS) was completed by 23 men and 5 women participants on the first and last days of the Warrior Games. The participants were separated into 2 groups: those who had participated in organized sporting events for more than 1 year (experienced; n=14) and those who had less than 1 year of experience (novice; n=14). A mixed-model ANOVA was used to assess pre–post changes and the effect of experience on total TOPS scores. Results: Overall participation in the Warrior Games did not change the performance strategies used by the participants. However, experienced participants had higher post-competition sub-scale scores than novice participants in the categories of self-talk, goal setting, and activation ( p<0.05). Discussion: While participation in a single Warrior Games event did not appear to change participants' short-term psychological thought processes around competition and practice, more than 1 year of participation in organized sporting events was associated with improved skills.

Abstract
Purpose: The mechanisms involved in the coordination of muscle activity are not completely known: to investigate adaptive changes in human motor cortex Transcranial magnetic stimulation (TMS) was often used. The sport models are frequently used to study how the training may affect the corticospinal system excitability: Karate represents a valuable sport model for this kind of investigations for its high levels of coordination required to athletes. This study was aimed at examining possible changes in the resting motor threshold (rMT) and in the corticospinal response in karate athletes, and at determining whether athletes are characterized by a specific value of rMT. Methods: We recruited 25 right-handed young karate athletes and 25 matched non-athletes. TMS was applied to primary motor cortex (M1). Motor evoked potential (MEP) were recorded by two electrodes placed above the first dorsal interosseous (FDI) muscle. We considered MEP latencies and amplitudes at rMT, 110% of rMT, and 120% of rMT. Results: The two groups were similar for age (p > 0.05), height (p > 0.05) and body mass (p > 0.05). The TMS had a 70-mm figure-of-eight coil and a maximum output of 2.2 T, placed over the left motor cortex. During the stimulation, a mechanical arm kept the coil tangential to the scalp, with the handle at 45° respect to the midline. The SofTaxic navigator system (E.M.S. Italy, www.emsmedical.net) was used in order to correctly identifying and repeating the stimulation for every subject. Compared to non-athletes, athletes showed a lower resting motor threshold (p < 0.001). Furthermore, athletes had a lower MEP latency (p < 0.001) and a higher MEP amplitude (p < 0.001) compared to non-athletes. Moreover, a ROC curve for rMT was found significant (area: 0.907; sensitivity 84%, specificity 76%). Conclusions: As the main finding, the present study showed significant differences in cortical excitability between athletes and non-athletes. The training can improve cortical excitability inducing athletes' modifications, as demonstrated in rMT and MEP values. These finding support the hypothesis that the sport practice determines specific brain organizations in relationship with the sport challenges.

Abstract
OBJECTIVE To compare the long-term effects of external focus (EF) and internal focus (IF) of attention after 4 weeks of arm training. DESIGN Randomized, repeated-measures, mixed analysis of variance. SETTING Outpatient clinic. PARTICIPANTS Individuals with stroke and moderate-to-severe arm impairment living in the community (N=33; withdrawals: n=3). INTERVENTIONS Four-week arm training protocol on a robotic device (12 sessions). MAIN OUTCOME MEASURES Joint independence, Fugl-Meyer Assessment, and Wolf Motor Function Test measured at baseline, discharge, and 4-week follow-up. RESULTS There were no between-group effects for attentional focus. Participants in both groups improved significantly on all outcome measures from baseline to discharge and maintained those changes at 4-week follow-up regardless of group assignment (joint independence EF condition: F1.6,45.4=17.74; P<.0005; partial η2=.39; joint independence IF condition: F2,56=18.66; P<.0005; partial η2=.40; Fugl-Meyer Assessment: F2,56=27.83; P<.0005; partial η2=.50; Wolf Motor Function Test: F2,56=14.05; P<.0005; partial η2=.35). CONCLUSIONS There were no differences in retention of motor skills between EF and IF participants 4 weeks after arm training, suggesting that individuals with moderate-to-severe arm impairment may not experience the advantages of an EF found in healthy individuals. Attentional focus is most likely not an active ingredient for retention of trained motor skills for individuals with moderate-to-severe arm impairment, whereas dosage and intensity of practice appear to be pivotal. Future studies should investigate the long-term effects of attentional focus for individuals with mild arm impairment.

Abstract
Context: Neuromuscular alterations are a major causal factor of primary and secondary injuries. Though injury prevention programs have experienced some success, rates of injuries have not declined, and after injury, individuals often return to activity with functionality below clinical recommendations. Considering alternative therapies to the conventional concentric exercise approach, such as one that can target neuromuscular injury risk and postinjury alterations, may provide for more effective injury prevention and rehabilitation protocols. Evidence Acquisition: Peer-reviewed sources available on the Web of Science and MEDLINE databases from 2000 through 2016 were gathered using searches associated with the keywords eccentric exercise, injury prevention, and neuromuscular control. Hypothesis: Eccentric exercise will reduce injury risk by targeting specific neural and morphologic alterations that precipitate neuromuscular dysfunction. Study Design: Clinical review. Level of Evidence: Level 4. Results: Neuromuscular control is influenced by alterations in muscle morphology and neural activity. Eccentric exercise beneficially modifies several underlying factors of muscle morphology (fiber typing, cross-sectional area, working range, and pennation angle), and emerging evidence indicates that eccentric exercise is also beneficial to peripheral and central neural activity (alpha motorneuron recruitment/firing, sarcolemma activity, corticospinal excitability, and brain activation). Conclusion: There is mounting evidence that eccentric exercise is not only a therapeutic intervention influencing muscle morphology but also targets unique alterations in neuromuscular control, influencing injury risk.

Abstract
BACKGROUND Degrees in health disciplines need a balance of theoretical knowledge and sufficient clinical practice to meet registration requirements, in particular those requiring specialist skills such as the use of scalpels and other small instruments, such as podiatry. However, despite this requirement there is a scarcity of literature and research to inform teaching of these particular manual clinical skills. Therefore, the aims of this study were to determine the current approaches being used to teach manual skills, in particular scalpel skills, in university podiatry programs in Australia and New Zealand, and to explore what issues, challenges and innovations exist. METHODS A qualitative study, consisting of semi-structured interviews with staff at eight university podiatry programs in Australia and New Zealand was undertaken to determine how these skills are taught and evaluated, and how poor performers are managed. A conventional content analysis technique was used to analyse and code interview data, with the resultant categories reported. RESULTS Approaches to teaching manual clinical skills, in particular scalpel skills, appear to be consistent between university programs in Australia and New Zealand in utilising didactic-style content, demonstration, physical practice on inanimate objects and real skin, and often the use of supplementary audio-visual material. The main reported differences between programs were in methods and processes of practice, with controversy regarding the use of inanimate objects versus real skin for practice. CONCLUSIONS Despite a lack of research and literature surrounding this topic, the approach to teaching is relatively consistent between programs with greatest disparity being the structure and duration of practice. Key issues for teaching staff in teaching manual skills were students' clinical exposure, motivation, levels of anxiety and dexterity.

Abstract
BACKGROUND No effective cure exists for knee osteoarthritis (OA). Low-burden self-management strategies that can slow disease progression are needed. Bone marrow lesions (BMLs) are a source of knee pain and accelerate cartilage loss. Importantly, they may be responsive to biomechanical off-loading treatments. OBJECTIVE The study objective is to investigate whether, in people with medial tibiofemoral OA, daily cane use for 12 weeks reduces the volume of medial tibiofemoral BMLs and improves pain, physical function, and health-related quality of life. DESIGN This study will be an assessor-masked, 2-arm, parallel-group, multisite randomized controlled trial. SETTING The community will serve as the setting for this study. PARTICIPANTS The study participants will be people who are 50 years old or older and have medial tibiofemoral OA and at least 1 medial tibiofemoral BML. INTERVENTION The participants will be allocated to either the cane group (using a cane daily whenever walking for 12 weeks) or the control group (not using any gait aid for 12 weeks). MEASUREMENTS Outcomes will be measured at baseline and 13 weeks. The primary outcome will be total medial tibiofemoral BML volume measured from magnetic resonance imaging. Secondary outcomes will include BML volume of the medial tibia and/or femur, knee pain overall and on walking, physical function, participant-perceived global change, and health-related quality of life. Additional measures will include physical activity, cointerventions, adverse events, participation, participant demographics, cane training process measures and feasibility, barriers to and facilitators of cane use, and loss to follow-up. LIMITATIONS People who are morbidly obese will not be included because of difficulties with magnetic resonance imaging. CONCLUSIONS The findings of this study will help to determine whether cane use can alter disease progression in people with medial tibiofemoral OA and/or influence clinical symptoms. This study may directly influence clinical guidelines for the management of knee OA.

Abstract
This study examined two different videotaped instructional models on subsequent motor and verbal behaviors of adults ( N = 9) learning how to lift properly. The correct model group viewed a narrated videotape of a skilled individual demonstrating lifting; the learning model group viewed a videotape of an unskilled individual being taught lifting by an instructor, and the controls received no intervention. Adults lifted from floor to waist a plastic crate during 15 acquisition and 3 retention trials and lowered the crate from waist to floor during 3 transfer trials. Learning and correct model motor performances were similar yet higher than those of controls during acquisition and transfer trials. Verbal reports indicated learning, and correct models generated more extensive and associated mechanical concepts than controls yet rarely monitored such concepts during performance. A single presentation of videotapes of proper lifting using either correct or learning models is effective in enhancing motor performance and proper lifting knowledge.

Abstract
Background It is known that general gait training improves lower extremity muscle strength and endurance in Diabetes Neuropathy (DN). But, it is still unknown whether Task-Oriented (TO) gait training would change gait biomechanics and the risk of falling in DN. TO gait training focuses on promoting timing and coordination of lower extremity movements through goal-directed practices with sufficient repetition. Methods A group of 14 patients with DN participated in a time-series study. All subjects participated in four sessions of assessments (Initial, Pre, Post and Follow-Up). Training was twice a week for 12 weeks. Vertical and horizontal Ground Reaction Forces (GRF), Time Get up and Go (TGUG) and Fall Efficacy Scale-International (FES-I) were evaluated. Gait training started with stepping patterns that progressively changed to complicated patterns of walking. Then, training continued combining walking patterns with upper extremity activities and then ended with treadmill-paced practice. Results DN patients significantly increased Second Vertical Peak Force and Horizontal Propulsive Force in addition decrease in Minimum Vertical Force. TGUG significantly decreased while FES-I reflected significant increase after gait training. Discussion Conclusively, training not only improved gait performance, confidence in daily activities and attenuated risk of falling, but also helped DN patients to improve feet biomechanics, muscles timing and coordination. Conclusions Gait training with respect to principles of motor learning allowed patients to effectively improve through sessions.

Functional Assessment of Corticospinal System Excitability in Karate Athletes. PLoS One 2016; 11:e0155998.

Abstract
Objectives To investigate the involvement of the primary motor cortex (M1) in the coordination performance of karate athletes through transcranial magnetic stimulation (TMS). Methods Thirteen right-handed male karate athletes (25.0±5.0 years) and 13 matched non-athlete controls (26.7±6.2 years) were enrolled. A single-pulse TMS was applied using a figure-eight coil stimulator. Resting motor threshold (rMT) was determined. Surface electromyography was recorded from the first dorsal interosseous muscle. Motor evoked potential (MEP) latencies and amplitudes at rMT, 110%, and 120% of rMT were considered. Functional assessment of the coordination performance was assessed by in-phase (IP) and anti-phase (AP) homolateral hand and foot coordination tasks performed at 80, 120, and 180 bpm. Results Compared to controls, athletes showed lower rMT (p<0.01), shorter MEP latency (p<0.01) and higher MEP amplitude (p<0.01), with a significant correlation (r = 0.50, p<0.01) between rMT and MEP latency. Coordination decreased with increasing velocity, and better IP performances emerged compared to AP ones (p<0.001). In general, a high correlation between rMT and coordination tasks was found for both IP and AP conditions. Conclusion With respect to controls, karate athletes present a higher corticospinal excitability indicating the presence of an activity-dependent alteration in the balance and interactions between inhibitory and facilitatory circuits determining the final output from the M1. Furthermore, the high correlation between corticospinal excitability and coordination performance could support sport-specific neurophysiological arrangements.

Abstract
Multilateral teleoperated robots can be used to train humans to perform complex tasks that require collaborative interaction and expert supervision, such as laparoscopic surgical procedures. In this paper, we explain the design and performance evaluation of a shared-control architecture that can be used in trilateral teleoperated training robots. The architecture includes dominance and observation factors inspired by the determinants of motor learning in humans, including observational practice, focus of attention, feedback and augmented feedback, and self-controlled practice. Toward the validation of such an architecture, we (1) verify the stability of a trilateral system by applying Llewellyn's criterion on a two-port equivalent architecture, and (2) demonstrate that system transparency remains generally invariant across relevant observation factors and movement frequencies. In a preliminary experimental study, a dyad of two human users (one novice, one expert) collaborated on the control of a robot to follow a trajectory. The experiment showed that the framework can be used to modulate the efforts of the users and adjust the source and level of haptic feedback to the novice user.

Abstract
Background: Feedback can improve task learning in children with developmental coordination disorder (DCD). However, the frequency and type of feedback may play different role in learning and needs to more investigations. Objectives: The aim of this study was to evaluate the acquisition and retention of new feedback skills in children with DCD under different frequency of self-control and control examiner feedback. Materials and Methods: In this quasi-experimental study with pretest-posttest design, participants based on their retention were divided into four feedback groups: self-controlled feedback groups with frequencies of 50% and75%, experimenter controls with frequencies of 50% and 75%. The study sample consisted of 24 boys with DCD aged between 9 to 11 years old in Ahvaz City, Iran. Then subjects practiced 30 throwing (6 blocks of 5 attempts) in eighth session. Acquisition test immediately after the last training session, and then the retention test were taken. Data were analyzed using the paired t-test, ANOVA and Tukey tests. Results: The results showed no significant difference between groups in the acquisition phase (P > 0.05). However,in the retention session, group of self-control showed better performance than the control tester group (P < 0.05). Conclusions: Based on the current findings, self-control feedback with high frequency leads to more learning in DCD children. The results of this study can be used in rehabilitation programs to improve performance and learning in children with DCD.

Effects of acupuncture and computer-assisted cognitive training for post-stroke attention deficits: study protocol for a randomized controlled trial. Trials 2015; 16:546. [PMID: 26631161 PMCID: PMC4667410 DOI: 10.1186/s13063-015-1054-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2015] [Accepted: 11/12/2015] [Indexed: 11/20/2022] Open
Abstract
Background A majority of stroke survivors present with cognitive impairments. Attention disturbance, which leads to impaired concentration and overall reduced cognitive functions, is strongly associated with stroke. The clinical efficacy of acupuncture with Baihui (GV20) and Shenting (GV24) as well as computer-assisted cognitive training in stroke and post-stroke cognitive impairment have both been demonstrated in previous studies. To date, no systematic comparison of these exists and the potential beneficial effects of a combined application are yet to be examined. The main objective of this pilot study is to evaluate the effects of computer-assisted cognitive training compared to acupuncture on the outcomes of attention assessments. The second objective is to test the effects of a combined cognitive intervention that incorporates computer-assisted cognitive training and acupuncture (ACoTrain). Methods/Design An international multicentre, single-blinded, randomised controlled pilot trial will be conducted. In a 1:1:1 ratio, 60 inpatients with post-stroke cognitive dysfunction will be randomly allocated into either the acupuncture group, the computer-assisted cognitive training group, or the ACoTrain group in addition to their individual rehabilitation programme. The intervention period of this pilot trial will last 4 weeks (30 minutes per day, 5 days per week, Monday to Friday). The primary outcome is the test battery for attentional performance. The secondary outcomes include the Trail Making Test, Test des Deux Barrages, National Institute of Health Stroke Scale, and Modified Barthel Index for assessment of daily life competence, and the EuroQol Questionnaire for health-related quality of life. Discussion This trial mainly focuses on evaluating the effects of computer-assisted cognitive training compared to acupuncture on the outcomes of attention assessments. The results of this pilot trial are expected to provide new insights on how Eastern and Western medicine can complement one another and improve the treatment of cognitive impairments in early stroke rehabilitation. Including patients with different cultural backgrounds allows a more generalisable interpretation of the results but also poses risks of performance bias. Using standardised and well-described assessments, validated for each region, is pivotal to allow pooling of the data. Trial registration Clinical Trails.gov ID: NCT02324959 (8 December 2014)
