1.Exercise-Induced Pain Reduction and Its Central Mechanism in Patients with Chronic Pain
Clinical Pain 2023;22(1):29-32
For the effective rehabilitation of chronic pain, it is necessary to know the changes in the pain networks of patients with chronic pain. There is a need for attention to changes in emotional pain networks and cognitive pain networks. In patients with chronic pain, post-exercise pain reduction is less pronounced than in those without chronic pain. In order to achieve the exercise effect, emotional problems must be considered in addition to the patient's physical changes. In addition, a detailed prior explanation is needed to raise the expectations for exercise effect, moreover, in order to continue exercising for a safe and long period, exercise suitable for patients should be selected and low-intensity exercise protocols should be provided.

Lance-Adams syndrome (LAS) is a rare neurological disorder that may occur after cardiopulmonary resuscitation. The LAS is usually caused by hypoxic changes.Neuroimaging studies show that the brain pathology of LAS patients is not uniform, and the pathophysiology of the myoclonus can vary from patient to patient. Our case study contributes to this etiological heterogeneity by neuroimaging and transcranial magnetic stimulation (TMS). In patients with rare brain conditions such as LAS, a combination of brain stimulation methods, such as TMS, and diffusion tensor imaging can provide insights into this condition's pathophysiology. These insights can facilitate the development of more effective therapies.

Objective:
To verify the pharyngeal width at rest as a measurement that could be used to assess changes in the degree of dysphagia over time in stroke patients.
Methods:
In a cohort of stroke patients, we performed serial measurements of the pharyngeal width at the midpoints of the second (C2) and third (C3) cervical vertebral bodies using lateral neck X-rays while the patients were at rest. The JOSCYL width, a parameter named after the first initial of each developers’ surname and defined as the average value of the upper and lower pharyngeal widths, was used to formulate the JOSCYL scale, which was calculated as the JOSCYL width × 100eck circumference. All patients also underwent serial videofluoroscopic swallowing studies (VFSSs). The Spearman correlation analysis was used to detect correlations between the serial VFSS results, JOSCYL widths, and JOSCYL scale values.
Results:
Over time, we observed significant positive and negative correlations of change in the JOSCYL width and scale with changes in the Penetration-Aspiration Scale and the Dysphagia Outcome and Severity Scale scores, respectively.
Conclusion
The JOSCYL width and JOSCYL scale clearly reflected changes in dysphagia in stroke patients over time. These parameters may provide an easier method for evaluating whether post-stroke dysphagia has been alleviated.

BACKGROUND: We utilized diffusion tensor imaging (DTI) to evaluate the cerebral white matter changes that are associated with phantom limb pain in patients with unilateral arm amputation. It was anticipated that this would complement previous research in which we had shown that changes in cerebral blood volume were associated with the cerebral pain network. METHODS: Ten patients with phantom limb pain due to unilateral arm amputation and sixteen healthy age-matched controls were enrolled. The intensity of phantom limb pain was measured by the visual analogue scale (VAS) and depressive mood was assessed by the Hamilton depression rating scale. Diffusion tensor-derived parameters, including fractional anisotropy, mean diffusivity, axial diffusivity (AD), and radial diffusivity (RD), were computed from the DTI. RESULTS: Compared with controls, the cases had alterations in the cerebral white matter as a consequence of phantom limb pain, manifesting a higher AD of white matter in both hemispheres symmetrically after adjusting for individual depressive moods. In addition, there were associations between the RD of white matter and VAS scores primarily in the hemispheres related to the missing hand and in the corpus callosum. CONCLUSIONS: The phantom limb pain after unilateral arm amputation induced plasticity in the white matter. We conclude that loss of white matter integrity, particularly in the hemisphere connected with the missing hand, is significantly correlated with phantom limb pain.

OBJECTIVE: To develop a new tool for aspiration risk prediction based on pharyngeal width at rest in older adults with symptoms of aspiration. METHODS: Lateral cervical spine roentgenograms were obtained from 33 older adult patients who complained of dysphagia and from 33 healthy, age-matched controls. Pharyngeal width at rest was measured at two points. We named the average of these two pharyngeal widths ‘JOSCYL Width’, calculated ‘JOSCYL Scale’, and compared these parameters between dysphagia and control groups. Correlations of individual JOSCYL Width and JOSCYL Scale, with Penetration Aspiration Scale (PAS) and Dysphagia Outcome and Severity Scale (DOSS) scores were analyzed for the dysphagia group. To determine optimal cutoff points for predicting aspiration, a receiver operating characteristic curve analysis was performed on JOSCYL Width and JOSCYL Scale. RESULTS: Both JOSCYL Width and JOSCYL Scale of the dysphagia group were larger than those of the control group (p<0.001). The correlation between JOSCYL Width and severity of dysphagia was significant for the dysphagia group (PAS p=0.007; DOSS p=0.012). The correlation between JOSCYL Scale and the severity of dysphagia was also significant for the dysphagia group (PAS p=0.009; DOSS p=0.011). Optimal cutoffs for JOSCYL Width and JOSCYL Scale for predicting aspiration were 20.0 mm and 5.9, respectively. CONCLUSION: JOSCYL Width and JOSCYL Scale can be new indicators for predicting aspiration in older adults. They are both precise and easy to use.

Annals of Rehabilitation Medicine 2019;43(1):106-110
Traumatic brain injury is a main cause of long-term neurological disability, and many patients suffer from cognitive impairment for a lengthy period. Cognitive impairment is a fatal malady to that limits active rehabilitation, and functional recovery in patients with traumatic brain injury. In severe cases, it is impossible to assess cognitive function precisely, and severe cognitive impairment makes it difficult to establish a rehabilitation plan, as well as evaluate the course of rehabilitation. Evaluation of cognitive function is essential for establishing a rehabilitation plan, as well as evaluating the course of rehabilitation. We report a case of the analysis of electroencephalography with global synchronization index and low-resolution brain electromagnetic tomography applied, for evaluation of cognitive function that was difficult with conventional tests, due to severe cognitive impairment in a 77-year-old male patient that experienced traumatic brain injury.

OBJECTIVE: To explore plastic changes in the red nucleus (RN) of stroke patients with severe corticospinal tract (CST) injury as a compensatory mechanism for recovery of hand function. METHODS: The moderate group (MG) comprised 5 patients with synergistic hand grasp movement combined with limited extension, and the severe group (SG) included 5 patients with synergistic hand grasp movement alone. The control group (CG) included 5 healthy subjects. Motor assessment was measured by Motricity Index (MI). Diffusion tensor imaging was analyzed using fractional anisotropy (FA) and radial diffusivity (RD) in the individual regions of interest (ROIs)—bilateral internal capsule and anterior pons for CST injury and bilateral RN for rubrospinal tract (RST) injury. RESULTS: The SG showed a significantly lower MI score than the MG mainly due to differences in hand subscores. Significantly reduced FA was observed in both MG and SG compared with CG, while SG showed increased MD and RD in the affected ROIs of CST, and increased FA on the unaffected side compared with CG. However, in the RN ROI, a significantly increased FA and decreased RD on the unaffected side similar to the affected side were found only in the SG. The relative index of FA was lower and RD in SG was higher than in CG in RST. CONCLUSION: The diffusion metrics of RST showed changes in patients with severe CST injury, suggesting that RST may play a role in the recovery of hand function in patients with severe CST injury.

9.Cerebral Blood Volume Magnetic Resonance Imaging.
Brain & Neurorehabilitation 2018;11(2):e18-
Cerebral blood volume (CBV) is a hemodynamic correlate of oxygen metabolism and changes due to neuronal activity. CBV alteration may precede other hemodynamic correlates and provide an early indication of hemodynamic impairment. CBV can be easily quantified using magnetic resonance imaging (MRI); moreover, CBV MRI has a strong point of high resolution compared to other neuroimaging modalities. The early and accurate assessments of cerebral metabolism and the brain map with the high resolution of CBV MRI enable advanced neurorehabilitation examinations in a neuroimaging study.

“Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” is the 3rd edition of clinical practice guideline (CPG) for stroke rehabilitation in Korea, which updates the 2nd edition published in 2014. Forty-two specialists in stroke rehabilitation from 21 universities and 4 rehabilitation hospitals and 4 consultants participated in this update. The purpose of this CPG is to provide optimum practical guidelines for stroke rehabilitation teams to make a decision when they manage stroke patients and ultimately, to help stroke patients obtain maximal functional recovery and return to the society. The recent two CPGs from Canada (2015) and USA (2016) and articles that were published following the 2nd edition were used to develop this 3rd edition of CPG for stroke rehabilitation in Korea. The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. Good Practice Point was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” consists of ‘Chapter 1; Introduction of Stroke Rehabilitation’, ‘Chapter 2; Rehabilitation for Stroke Syndrome, ‘Chapter 3; Rehabilitation for Returning to the Society’, and ‘Chapter 4; Advanced Technique for Stroke Rehabilitation’. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” will provide direction and standardization for acute, subacute and chronic stroke rehabilitation in Korea.
