Effectiveness of mixed reality-based rehabilitation on hands and fingers by individual finger-movement tracking in patients with stroke.

Background: Mixed reality (MR) is helpful in hand training for patients with stroke, allowing them to fully submerge in a virtual space while interacting with real objects. The recognition of individual finger movements is required for MR rehabilitation. This study aimed to assess the effectiveness of updated MR-board 2, adding finger training for patients with stroke.

The feasibility of mixed reality-based upper extremity self-training for patients with stroke-A pilot study.

Unlabelled: Mixed reality (MR), which combines virtual reality and tangible objects, can be used for repetitive training by patients with stroke, allowing them to be immersed in a virtual environment while maintaining their perception of the real world. We developed an MR-based rehabilitation board (MR-board) for the upper limb, particularly for hand rehabilitation, and aimed to demonstrate the feasibility of the MR-board as a self-training rehabilitation tool for the upper extremity in stroke patients. The MR-board contains five gamified programs that train upper-extremity movements by using the affected hand and six differently shaped objects.

Injury of the Thalamocingulate Tract in the Papez Circuit in Patients with Mild Traumatic Brain Injury.

The thalamocingulate tract between the anterior thalamic nuclei and the cingulate gyrus is a part of the Papez circuit. Using diffusion tensor tractography, injury of the thalamocingulate tract was investigated in patients with mild traumatic brain injury. Two patients (patient 1: a 58-yr-old woman and patient 2: a 49-yr-old man) with head trauma resulting from a car accident were enrolled.

Influence of abutment materials on the implant-abutment joint stability in internal conical connection type implant systems.

Purpose: This study evaluated the influence of abutment materials on the stability of the implant-abutment joint in internal conical connection type implant systems.

Materials And Methods: Internal conical connection type implants, cement-retained abutments, and tungsten carbide-coated abutment screws were used. The abutments were fabricated with commercially pure grade 3 titanium (group T3), commercially pure grade 4 titanium (group T4), or Ti-6Al-4V (group TA) (n=5, each).

Anatomical location and somatotopic organization of the corticospinal tract in the corona radiata of the normal human brain: a diffusion tensor tractography study.

The anatomical location and somatotopic organization of the corticospinal tract (CST) in the corona radiata (CR) of the normal human brain have not been studied using diffusion tensor tractography so far. In this study, the anatomical location and somatotopic organization of the CST in the CR were evaluated by determining the highest probabilistic locations and distances between the upper and lower extremities in the slices of upper and lower CR in the brain. In the mediolateral direction, the average of the highest probabilistic locations for the upper and lower extremities were 40.

Usefulness of the combined motor evoked and somatosensory evoked potentials for the predictive index of functional recovery after primary pontine hemorrhage.

Objective: To investigate the predictive index of functional recovery after primary pontine hemorrhage (PPH) using the combined motor evoked potential (MEP) and somatosensory evoked potential (SEP) in comparison to the hematoma volume and transverse diameter measured with computerized tomography.

Methods: Patients (n=14) with PPH were divided into good- and poor-outcome groups according to the modified Rankin Score (mRS). We evaluated clinical manifestations, radiological characteristics, and the combined MEP and SEP responses.

Acute spinal subdural hematoma with hemiplegia after acupuncture: a case report and review of the literature.

Background Context: Subdural spinal hematoma (SDH) is a very rare entity; however, it can lead to serious complications resulting from injuries to the spinal cord and roots. Although acupuncture has been a popular method for the management of pain control, we encountered the first case of SDH after acupuncture.

Purpose: The purpose of this case report was to present the first case of subdural hematoma after acupuncture and the reasons for the risks of blind cervical acupuncture.

Chronic traumatic spinal epidural hematoma in a child.

Spinal epidural hematoma (SEH) can lead to progressive neurological deficits that are the result of spinal cord compression. Most of the reported cases of SEH had nontraumatic origins, and they were mainly in the acute stage. Traumatic SEH in a child is rare, and it is also difficult to diagnose because of the nonspecific pain and irritability of the child.

Identification of the medial lemniscus in the human brain: combined study of functional MRI and diffusion tensor tractography.

The medial lemniscus (ML) plays a critical role in sensory function and skillful movement. Using combined functional MRI (fMRI) and diffusion tensor tractography (DTT), we attempted to identify the ML pathway and quantify the characteristics of the ML compared to the corticospinal tract (CST). Eleven young healthy subjects without any history of neurological disorder were recruited for this study.

Motor outcome prediction using diffusion tensor tractography in pontine infarct.

We investigated whether the integrity of the corticospinal tract classified by diffusion tensor tractography (DTT) can predict the motor outcome in 25 patients with pontine infarct. DTTs were obtained in the early stage of stroke (5-30 days) and were classified into two groups (type A: the integrity of corticospinal tract was preserved around the infarct; type B: corticospinal tract was interrupted). DTT type A patients showed better motor function than the type B patients at 6 months after onset.
