Washabaugh EP, Foley SA, Czopek EG and Krishnan C
Intracortical inhibitory/faciliatory measures are affected after stroke; however, the evidence is conflicting.
Gamified Practice Improves Paretic Arm Motor Behavior in Individuals With Stroke
Rubino C, Lakhani B, Larssen BC, Kraeutner SN, Andrushko JW, Borich MR and Boyd LA
Stroke is a heterogeneous condition, making choice of treatment, and determination of how to structure rehabilitation outcomes difficult. Individualized goal-directed and repetitive physical practice is an important determinant of motor learning. Yet, many investigations of motor learning after stroke deliver task practice without consideration of individual capability of the learner.
Hemodynamics of the Frontopolar and Dorsolateral Pre-Frontal Cortex in People with Multiple Sclerosis During Walking, Cognitive Subtraction, and Cognitive-Motor Dual-Task
Santinelli FB, Veldkamp R, Vitório R, Kos D, Vos M, Nijssen R, DeLuca J, Ramari C and Feys P
Higher cortical activity has been observed in people with multiple sclerosis (pwMS) during walking and dual-tasking. However, further studies in overground walking and considering pre-frontal cortex (PFC) sub-areas are necessary.

Hernandez ME, Motl RW, Foley FW, Picone MA, Izzetoglu M, Lipton ML, Wagshul M and Holtzer R
Mobility and cognitive impairment are prevalent and co-occurring in older adults with multiple sclerosis (OAMS), yet there is limited research concerning the role of disability status in the cognitive control of gait among OAMS.
Meeting the Needs of People With Severe Quadriplegia in the 21st Century: The Case for Implanted Brain-Computer Interfaces
Sawyer A, Cooke L, Breyman E, Spohn S, Edelman S, Saravanan K and Putrino D
In recent decades, there has been a widespread adoption of digital devices among the non-disabled population. The pervasive integration of digital devices has revolutionized how the majority of the population manages daily activities. Most of us now depend on digital platforms and services to conduct activities across the domains of communication, finance, healthcare, and work. However, a clear disparity exists for people who live with severe quadriplegia, who largely lack access to tools that would enable them to perform daily tasks digitally and communicate effectively with their environment.
Supplementary and Premotor Cortical Activation During Manual Dexterity Involving Motor Imagery in Multiple Sclerosis: A Functional Near-Infrared Spectroscopy Study
Sadot S, Dreyer-Alster S and Kalron A
Investigating brain activation during motor imagery (MI) tasks in people with multiple sclerosis (pwMS) can increase the knowledge of the neural mechanisms underlying motor dysfunction in MS and, hopefully, aid in developing improved rehabilitation strategies.
Discordance Between Balance Ability and Perception Is Associated With Falls in Parkinson's Disease: A Coordinated Analysis
Longhurst JK, Hooyman A, Landers MR, Mancini M, Franzén E, Leavy B, Johansson H and Peterson D
The congruence or discordance between actual and perceived balance ability has been proposed to be linked to functional outcomes such as falls. However, gaps remain in our ability to quantify discordance, and its relationship to relevant outcomes.
Relationships Between Cognitive Impairments and Motor Learning After Stroke: A Scoping Review
Rajda CM, Desabrais K and Levin MF
Stroke is one of the leading causes of chronic disability worldwide. Sensorimotor recovery relies on principles of motor learning for the improvement of movement and sensorimotor function after stroke. Motor learning engages several cognitive processes to effectively learn and retain new motor skills. However, cognitive impairments are common and often coexist with motor impairments after stroke. The specific relationships between poststroke cognitive impairments and motor learning have not been determined.
Prediction of Upper Limb Motor Recovery by the PREP2 Algorithm in a Nonselected Population: External Validation and Influence of Cognitive Syndromes
Millot S, Daghsen L, Checkouri T, Wittwer A, Valabregue R, Galanaud D, Charles Lamy J and Rosso C
Early prediction of poststroke motor recovery is challenging in clinical settings. The Prediction recovery potential (PREP2) algorithm is the most accurate approach for prediction of Upper Limb function available to date but lacks external validation.
Effects of Balance Exercise Interventions on Balance-Related Performance in People With Multiple Sclerosis: A Systematic Review and a Meta-Analysis of Randomized Controlled Trials
Wallin A, Johansson S, Brincks J, Dalgas U, Franzén E and Callesen J
Balance training covers a range of different modalities and complexity levels for people with multiple sclerosis (MS). When evaluating the effects of balance training across different kinds of interventions, determination of the specific intervention content that predict effects are needed.
Brain-Hand Function Relationships Based on Level of Grasp Function in Chronic Left-Hemisphere Stroke
Rizor E, Fridriksson J, Peters DM, Rorden C, Bonilha L, Yourganov G, Fritz SL and Stewart JC
The biomarkers of hand function may differ based on level of motor impairment after stroke. The objective of this study was to determine the relationship between resting state functional connectivity (RsFC) and unimanual contralesional hand function after stroke and whether brain-behavior relationships differ based on level of grasp function.
Complex Exercises Improve Cognition in People With Parkinson's Disease and Freezing of Gait
Silva-Batista C, Almeida FO, Batista A, Barbosa ER, Horak FB and Ugrinowitsch C
Evidence has suggested that cognitive decline may be a risk factor for freezing of gait (FOG) in Parkinson's disease (PD). Complex and challenging exercises have been suggested as potential rehabilitation strategies to decrease FOG severity and improve cognition; however, it is unknown whether improvement in cognition would explain decreased FOG severity following exercise.
Intensity-Dependent Effects of Low-Frequency Subthreshold rTMS on Primary Motor Cortex Excitability and Interhemispheric Inhibition in Elderly Participants: A Randomized Trial
Wischnewski M, Edwards L, Revill KP, Drake D, Hobbs G and Buetefisch CM
Low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) protocols targeting primary motor cortex (M1) are used in rehabilitation of neurological diseases for their therapeutic potential, safety, and tolerability. Although lower intensity LF-rTMS can modulate M1 neurophysiology, results are variable, and a systematic assessment of its dose effect is lacking.
Impairments in Proprioceptively-Referenced Limb and Eye Movements in Chronic Stroke
Tulimieri DT, Decarie A, Singh T and Semrau JA
Upper limb proprioceptive impairments are common after stroke and affect daily function. Recent work has shown that stroke survivors have difficulty using visual information to improve proprioception. It is unclear how eye movements are impacted to guide action of the arm after stroke. Here, we aimed to understand how upper limb proprioceptive impairments impact eye movements in individuals with stroke.

The prognosis of prolonged disorders of consciousness (pDoC) in children has consistently posed a formidable challenge in clinical decision-making.
Effects of a Wearable-Based Intervention on the Hemiparetic Upper Limb in Persons With Stroke: A Randomized Controlled Trial
Toh FM, Lam WWT, Cruz Gonzalez P and Fong KNK
Wearables have emerged as a transformative rehabilitation tool to provide self-directed training in the home. In this study, we examined the efficacy of a novel wearable device, "Smart Reminder" (SR), to provide home-based telerehabilitation for hemiparetic upper limb (UL) training in persons with stroke.
Delayed Cortical Responses During Reactive Balance After Stroke Associated With Slower Kinetics and Clinical Balance Dysfunction
Palmer JA, Payne AM, Mirdamadi JL, Ting LH and Borich MR
Slowed balance and mobility after stroke have been well-characterized. Yet the effects of unilateral cortical lesions on whole-body neuromechanical control is poorly understood, despite increased reliance on cortical resources for balance and mobility with aging. We tested whether individuals post stroke show impaired cortical responses evoked during reactive balance, and the effect of asymmetrical interlimb contributions to balance recovery and the evoked cortical response.
