Objective : This study aimed to investigate the effect of simultaneous application of peripheral nerve sensory stimulation and task-oriented training on the improvement of upper extremity motor function after stroke. Methods : This study included 29 patients with hemiplegia. The 14 subjects were in the peripheral nerve sensory stimulation and task-oriented training group for 4 weeks (30 min/d, 5 d/wk), while the 15 control group subjects underwent only task-oriented training for the same duration. The outcome measures were the percentage of voluntary baseline muscle contractions of the wrist and shoulder and Box and Block Test, grip and pinch strength, and Action Research Arm Test. Results : After 4 weeks, muscle activity of extensor carpi radialis, flexor carpi radialis and grip strength and Action Research Arm Test were significantly higher in the experimental group. Conclusion : Simultaneous application of the peripheral nerve sensory stimulation and task-oriented training was found to be superior to task-oriented training for improving upper extremity motor function of adults with stroke.

This study was carried out to evaluate the toxicity of ethanolic extracts of Morus alba L. branch (ME). In the reverse mutation test, Salmonella Typhimurium TA98, TA100, TA1535, TA1357, and Escherichia coli WP2uvrA were used to estimate the mutagenic potential of ME. Sprague-Dawley rats were orally administered ME at levels of 1,250, 2,500, and 5,000 mg/kg for the single-dose toxicity test and 500, 1,000, and 2,000 mg/kg/d for the repeated-dose toxicity test for 28 consecutive days. As expected, reverse mutation was not detected at any concentration of ME, regardless of application of the metabolic activation system with or without S9 mix. In the single-dose toxicity test, ME caused neither significant visible signs of toxicity nor mortality in rats, and $LD_{50}$ was estimated to be over 5,000 mg/kg. In the repeated-dose toxicity test, ME administration at 500, 1,000, and 2,000 mg/kg for 28 days to male or female rats did not result in mortality. Similarly, no toxicologically significant treatment-related changes in body weight, food intake, or organ weights were noted. Several hematological and biochemical parameters in both genders showed significant differences, but these were within normal ranges. These results support the safe use of ME.

The elbow joint is made up of three different bones. X-rays or other radiological exams are commonly used to diagnose elbow injuries or disorders caused by physical activity and external forces. Previous research on the elbow joint reported a new examination method that meets the imaging evaluation criteria in the tilt position by Z-axis elevation of the forearm. Therefore, this study aims to design an optimized instrument and develop an aid applicable to other upper extremity exams. After completing the 2D drawing and 3D modeling design, the final design divided into four parts was fabricated with a 3D printer using ABS plastic and assembled. The developed examination aid consists of a four-stage Z-axis elevation tilt angle function (0°, 5°, 10°, and 15°) and can rotate and fixate 360° in 1-degree increments. It was designed to withstand a maximum equivalent stress of 56.107 Pa and a displacement of 1.6548e-5 mm through structural analysis to address loading issues caused by cumulative frequency of use and physical utilization. In addition to X-ray exams of the elbow joint, the developed aid can be used for shoulder function tests by rotating the humerus and also be applied to MRI and CT exams as it is made of non-metallic materials. It will contribute to the accuracy and efficiency of medical imaging diagnosis through clinical applications of various devices and medical imaging exams in the future.

H-reflex is a kind of late respons which can be used for the proximal nerve conduction study. Also it is a useful and widely used nerve conduction technique es to look electrically at the monosynaptic reflex. Although recordable from all muscles theoretically, H-reflexes are most commonly recorded from the calf muscles following stimulation of the tibial nerve in the popliteal fossa. But in this study, We tried to establish the normal data and to evaluate the significance of the H-reflex study in cervical radiculopathy. H-reflexes were recorded from flexor carpi radialis (FCR) muscle, extensor carpi radialis (ECR) muscle, brachioradialis (BR) muscle, and abductor digiti minimi (ADM) muscle in 31 normal adults (62 cases) and 12 patients with cervical radiculopathy. The mean values of H-reflex latency in normal control group were $16.16{\pm}1.65$ msec in FCR; $15.99{\pm}1.25$ msec in ECR; $16.47{\pm}1.59$ msec in BR; $24.46{\pm}1.42$ msec in ADM. And the mean values of side to side difference of H-reflex latency were $0.47{\pm}0.48$ msec in FCR; $0.68{\pm}0.72$ msec in ECR; $0.63{\pm}0.43$ msec in BR; $22.31{\pm}1.24$ msec in ADM. Mean values of side to side differences of interlatency time were $0.49{\pm}0.47$ msec in FCR; $0.73{\pm}0.62$ msec in ECR; $0.79{\pm}0.71$ msec in BR; $0.69{\pm}0.44$ msec in ADM. Also, there were no significant differences in H-reflex latency between right and left side. H-reflex tests in patient group with cervical radiculopathy revealed abnormal findings in 11 out of 12 patients. These results suggest that H-reflex in the upper extremity would be helpful in the diagnosis of the cervical radiculopathy.

Histiocytic necrotizing lymphadenitis, which is also commonly referred to as Kikuchi's disease (KD), is a self-limiting disease of unknown etiology. It affects individuals of all ages, although it is usually seen in young women. However, only a few descriptions of this disease are available in the pediatric literature. KD is clinically characterized by cervical lymphadenopathy, high fever, myalgia, neutropenia and, rarely, cutaneous eruptions. Cutaneous manifestations have been reported in 16-40 percent of KD cases. The specific skin changes occurring in cases of KD have yet to be completely characterized. In most of the reported cases thus far, the lesions have been located on the face and upper extremities. In this report, we describe a case of pediatric Kikuchi's disease, occurring in a 9-year-old boy. The boy exhibited transient erythematous maculopapular skin lesions over the entirety of his body, including his lower extremities.

The purpose of this study was to provide useful data for clinical occupational therapy by examining the correlation between the use of affected and unaffected sides measured using an accelerometer and upper limb function in chronic stroke patients. In this study, accelerometer, Fugle-Meyer Assessment(FMA), Motor Activity Log(MAL), and Yonsei-Bilateral Activity Test(Y-BAT) was measured on 40 stroke patients who were hospitalized in Won-ju city Y hospital between May 2, 2019 and July 18, 2020. As a result of the study, there was a significant negative correlation between amount of use on the unaffected side and FMA and MAL's Amount of Use(AOU), Quality of Movement(QOM), the quality and satisfaction of performing both hands through Y-BAT. The amount of use on the affected side showed a significant positive correlation with FMA and MAL's AOU, QOM, satisfaction of performing both hands. This study is meaningful in that it suggested the possibility that the actual amount of use on the affected and unaffected side measured using an accelerometer could be used as an evaluation item for upper limb function in stroke patients.
