Introduction Dose (number of repetitions) has been suggested as a key element in the effectiveness rehabilitation exercises to promote motor recovery hemiparetic upper limb. However, tend be monotonous and require significant motivation continue, making it difficult increase exercise dose. To address this issue, gamification technology implemented self-engagement for people with hemiparesis continuing repetitive movements. This study aimed investigate how subjective perspectives,...

BACKGROUND: Meta-learning is a metacognitive function for successful, efficient learning in various tasks. While it possible that meta-learning linked to functional recovery stroke, has not been investigated previous clinical research on metacognition.AIM: Examine if individual ability associated with outcomes.DESIGN: Cohort study.SETTINGS: Rehabilitation ward Fujita Health University Hospital.POPULATION: Twenty-nine hemiparetic people after stroke.METHODS: The study measured sensorimotor...

Movement repetition is known to play a key role in promoting functional improvements or maintaining levels post-stroke hemiparetic patients. However, repetitive movements tend be monotonous, making it challenging for patients continue. Here, we developed new gamified system allow perform with enjoyment. The present study aimed examine the usability of subacute stroke patients.The exercise comprised an electromyography-controlled operating that enabled users virtual game by finger and wrist...

Abstract Transcranial magnetic stimulation has been used to assess plastic changes in the cortical motor representations of targeted muscles. The present study explored optimal settings and intensity for simultaneous mapping multiple upper‐limb muscles across segments. In 15 healthy volunteers, we evaluated simultaneously from one muscle shoulder, two upper arm, forearm, intrinsic hand muscles, using five intensities, ranging 40% 100% maximum stimulator output. We represented map area...

Introduction Contact electrical currents in humans stimulate peripheral nerves at frequencies of <100 kHz, producing sensations such as tingling. At above 100 heating becomes dominant, resulting a sensation warmth. When the current amplitude exceeds threshold, results discomfort or pain. In international guidelines and standards for human protection from electromagnetic fields, limit contact has been prescribed. Although types produced by low frequencies, i.e., approximately 50–60 Hz,...

Neural interactions between upper and lower limbs underlie motor coordination in humans. Specifically, limb voluntary muscle contraction can facilitate spinal corticospinal excitability of the muscles. However, little remains known on involvement somatosensory information arm-leg neural interactions. Here, we investigated effects electrically induced wrist flexion processing limbs. In Experiment 1, measured transcranial magnetic stimulation (TMS)-evoked evoked potentials (MEPs) resting...

Arm reaching, a fundamental function required for the upper extremities, is often impaired after stroke due to muscle weakness and abnormal synergies. Nonetheless, how aiming directions influence performance remains unclear. Here, we report that direction-dependent differences in quality quantity of reaching exist, surprisingly regardless presence or severity hemiparesis. This result highlights need consider task work area when designing rehabilitative training.

The application of 28 GHz millimeter-wave is prevalent owing to the global spread fifth-generation wireless communication systems. Its thermal effect a dominant factor which potentially causes pain and tissue damage body parts exposed millimeter waves. However, threshold this sensation, that is, degree change in skin temperature from baseline at first subjective response effects waves occurs, remains unclear. Here, we investigated sensation assessed its reliability when Twenty healthy adults...

Smiling during conversation occurs interactively between people and is known to build good interpersonal relationships. However, whether how much the amount that an individual smiles influenced by other person's smile has remained unclear. This study aimed quantify of two individuals' conversations investigate dependency one's (i.e., intensity frequency) on other.

Upper- and lower-limb neuromuscular electrical stimulation (NMES) is known to modulate the excitability of neural motor circuits. However, it remains unclear whether short-duration trunk muscle NMES could achieve similar neuromodulation effects. We assessed evoked potentials (MEPs) elicited through transcranial magnetic primary cortex representation extensor muscles evaluate corticospinal excitability. Moreover, cervicomedullary (CMEPs) were junction subcortical Twelve able-bodied...

Transcranial direct current stimulation (tDCS) is a technique that can noninvasively modulate neural states in targeted brain region. As cerebellar activity levels are associated with upper limb motor improvement after stroke, the cerebellum plausible target of tDCS. However, effect tDCS remains unclear. Here, we designed pilot study to assess: (1) feasibility aims examine effects combined an intensive rehabilitation approach based on concept constraint-induced movement therapy (CIMT) and...
