Because the sural nerve formation is highly variable, the possibility of anatomical variation should be considered when the sural sensory nerve action potential is of low amplitude and disproportionate to the neurologic evaluation.

BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) modulates cortical excitability and facilitates motor learning to improve motor recovery after stroke. Action observation (AO) therapy effectively facilitates physical training for motor memory formation. OBJECTIVE: To compare the effectiveness of rTMS alone with that of combined rTMS and AO for the functional recovery of upper extremity function in subacute stroke patients and to verify the safety of the interventions. METHODS: The

OBJECTIVE: Inspiratory and expiratory muscles are important for effective respiratory function. This study aimed to investigate the efficacy of bedside respiratory muscle training on pulmonary function and stroke-related disabilities in stroke rehabilitation. DESIGN: Patients with stroke (N = 40) in a rehabilitation unit were randomly assigned to either the intervention group (n1 = 20) or the control group (n2 = 20). Both groups participated in a conventional stroke rehabilitation program. Durin

BACKGROUND: Video fluoroscopic swallowing study (VFSS) is considered as the gold standard diagnostic tool for evaluating dysphagia. However, it is time consuming and labor intensive for the clinician to manually search the recorded long video image frame by frame to identify the instantaneous swallowing abnormality in VFSS images. Therefore, this study aims to present a deep leaning-based approach using transfer learning with a convolutional neural network (CNN) that automatically annotates phar

The association patterns of lesion topography and specific language deficits provide key insights into the specific underlying language pathways. Our meta-analysis results strongly support the dual pathway model of language processing, capturing the link between the different symptom complexes of aphasias and the different underlying location of damage.

This study investigated factors associated with aphasia severity at both 2 weeks and 3 months after stroke using demographic and clinical variables, brain diffusion tensor imaging (DTI) parameters, and lesion volume measurements. Patients with left hemisphere stroke were assessed at 2 weeks (n = 68) and at 3 months (n = 20) after stroke. Demographic, clinical, and neuroimaging data were collected; language functions were assessed using the Western Aphasia Battery. For neuroimaging, DTI parameter

The results of this study showed that an individualized home programme improved IADL performance in patients with cognitive dysfunction and may have a beneficial effect on cognition, as assessed by general cognitive measures.

BACKGROUND: To investigate the efficacy and usefulness of 12 sessions of overground robot-assisted gait training (RAGT) in subacute stroke patients. METHODS: In this pilot study, 17 subacute stroke survivors were randomly assigned to the intervention (n = 9) and control (n = 8) groups. In addition to the conventional stroke neurorehabilitation program, the intervention group received 30 minutes of overground exoskeletal RAGT, while the control group received 30 minutes of conventional gait train

Our results show that 3DUS could markedly decrease scanning time, and measurement of the median nerve cross-sectional area combined with morphologic analysis using 3DUS is a promising supplementary method for the diagnosis of carpal tunnel syndrome.

As the survival rate of traumatic brain injury increases, the burden of care for patients with traumatic brain injury is emerging as a socioeconomic issue and the discharge destination is one of the important outcome measures in the post-acute rehabilitation unit. To investigate the predictors of functional outcome and discharge destination in patients with traumatic brain injury after post-acute rehabilitation. A retrospective review was performed on 86 patients who were admitted to the rehabil

Lesions affecting the left fusiform gyrus (FG) commonly result in dyslexia and recovery largely depends on efficient reorganization of the reading network. We performed a follow-up fMRI study to elucidate the reorganization patterns of the FG according to the recovery of reading ability in two patients (MH with pure alexia and KM with alexia with agraphia) after stroke involving the left FG. Initially, MH was an effortful letter-by-letter (LBL) reader, and she improved to become a proficient LBL

Background Temporal changes in the structural connectivity of major language tracts after stroke and their contribution to aphasia recovery are unclear. Objective To investigate longitudinal arcuate fasciculus (AF) integrity changes and their relationship with post-stroke aphasia recovery using diffusion tensor imaging (DTI). Methods Thirty-five patients with aphasia due to first-ever left hemispheric stroke underwent the Korean version of the Western Aphasia Battery and DTI at 1- and 6-month po
