Journal of Korean Physical Therapy 2020;32(6):365-371
Objective:
To investigate the action observation effects of functional electrical stimulation (FES) on the communication between motor cortex and muscle through corticomuscular coherence (CMC) analysis.
Methods:
Electroencephalogram (EEG) and electromyogram (EMG) of 27 healthy, nonathlete subjects were measured during action observation, FES, and action observation with FES, which lasted for 7sper session for 10 times. All trials were repeated for 30 times. Simultaneously measured EEG raw data and rectified EMG signals were used to calculate CMC. Only confidence limit values above 0.0306 were used for analysis. CMC was divided into three frequency domains, andthe grand average coherence and peak coherence were computed. Repeated ANOVA was performed to analyze the coherence value difference for each condition’s frequency band.
Results:
CMC showed significant differences in peak coherence and average coherence between the conditions (p<0.05). Action observation application with FES in all frequency band showed the highest peak and average coherence value.
Conclusions
The results of this study are assumed to be the combination of increased eccentric information transfer from the sensory-motor cortex by action observation and an increased in concentric sensory input from the peripheral by the FES, suggesting that these are reflecting the sensorimotor integration process.
2.Effects of a Trunk Stabilization Exercise with Gym Ball on Scapular Position for Patients with Arthroscopic Rotator Cuff Repair
Journal of Korean Physical Therapy 2018;30(1):8-13
PURPOSE: The present study was to investigate effects of scapular position and pain on a trunk stabilization exercise with gym ball for patients with arthroscopic rotator cuff repair. METHODS: Subjects were patients after 2 weeks of rotator cuff repairs. Subjects were randomly assigned to conservative treatment group (CTG, n=10) or trunk stabilization with gym ball group (SBG, n=10), and participated one of those groups for 2 weeks. Measurements about pain and scapular position were assessed in before and after treatment programs. RESULTS: Pain reduced in both rest and night in SBG compared to CTG. In the case of scapular position, decreased scapular retraction (increased protraction) was found in CTG and vice versa in SBG. Reduced scapular anterior tilting was also found on SBG. CONCLUSION: The present study showed that early performed trunk stabilization with gym ball could bring a scapular alignment that increases subacromial space and reduces pain. This suggests early trunk stabilization with gym ball programs to restore shoulder functions for patients with rotator cuff repair.

Leptomeningeal carcinomatosis, an important and serious neurological complication of malignant cancers, is asso- ciated with severe disability and high mortality. It is most commonly seen in patients with breast cancer, lung cancer and malignant melanoma. However, leptomeningeal carcinomatosis induced by gastric cancer has been rarely reported, although gastric cancer is one of the most common causes of cancer-related deaths in Korea. We report a case of a 76- year-old woman with leptomeningeal carcinomatosis presenting as a neurological complication of gastric cancer and con- firmed by cytology examination of the cerebrospinal fluid and brain magnetic resonance imaging with gadolinium enhan-cement.

The deformities of micrognathia and glossoptosis in the newborn are frequently associated with a cleft palate, which is known as Pierre Robin sequence. Upper airway obstruction is the most serious problem in these patients. Treatment of Pierre Robin sequence includes either positional or surgical intervention. Mild cases are often managed in the prone position. However, when the patient fails to thrive due to chronic upper airway obstruction, or severe respiratory distress ensures despite positional treatment, surgical intervention is mandatory to relieve the obstruction. We experienced three infants with Pierre Robin sequence who showed a symptom triad of micrognathia, glossoptosis, and cleft palate. Intermittent cyanosis, depression of the chest, respiratory difficulty and feeding problems were also observed. To relieve severe upper airway obstruction caused by micrognathia and glossoptosis, we simultaneously performed modified tongue lip adhesion (TLA) and a subperiosteal release of the floor of the mouth (SRFM). Respiratory and feeding difficulties were relieved, the tongue positioned anteriorly, body weight increased, and mandibular growth improved. Simultaneous TLA and SRFM may constitute a simple and reliable method for surgical treatment of airway obstruction in patients with Pierre Robin sequence.

Hemiballism is a rare hyperkinetic involuntary movement disorder that presents with unilateral forceful, flinging, large amplitude of proximal limbs. The most consistent neuropathological findings in hemiballism are a lesion of the contralateral subthalamic nucleus and pallidosubthalamic tract. However, we experienced a patient with pure hemiballism as isolated manifestation of acute ischemic stroke without other neurological abnormal symptoms such as chorea or dystonia. Brain magnetic resonance image showed acute ischemic stroke in right caudate nucleus but not subthalamic nucleus.

BACKGROUND: Solid tumors require neovasculization for growth and metastasis. Recently, several angiogenic factors have been identified. Vascular endothelial growth factor (VEGF) is thought to be one such angiogenic factor and is also thought to be a selective mitogen for endothelial cells. In this study, we examined the expression of VEGF and its relationship with microvessel density, and we also determined its prognostic significance in gastric cancer patients. METHODS: One hundred one specimens resected from patients with gastric carcinomas were investigated by staining with a polyclonal antibody against VEGF. Correlations between the expression of VEGF, the microvessel density, various clinicopathologic factors, and the patient's survival were studied. RESULTS: The normal gastric mucosa was not immunoreactive with an anti-VEGF antibody. VEGF was mainly localized to the cytoplasm or the membrane of the carcinoma cell. Of the 101 tumors, strong VEGF expression was detected in 48 (47.5%) tumors. VEGF expression was correlated with depth of tumor invasion, lymph-node metastasis, and stage. Microvessel density, determined by immunohistochemical staining for CD31, was significantly higher in VEGF-strong tumors than in VEGF-weak tumors. Also, patients with VEGF-strong tumors had a significantly poorer prognosis than those with VEGF-weak tumors. However, multivariate analysis indicated that the expression of VEGF was not an independent prognostic factor in patients with gastric cancer. CONCLUSIONS: The fact that VEGF expression in gastric carcinomas was more prevalent in more advanced tumors means that VEGF may contribute to the progression of the tumor. Further study is needed to evaluate the significance of VEGF as a prognostic factor.

OBJECTIVES: This study was conducted to analyze the factors that affected the decision of claims for cerebrovascular disorders and cardiovascular diseases in chronically overworked workers, that submitted their claims after the reformation of approval standards in the Industrial Accident Compensation Insurance Act on 1 July 2008. METHODS: Of 2909 cases, who claimed between January 1. and December 31. 2009, 1046 cases were selected based on their worker's compensation record and investigated following 6 provincial committees for work-related diseases. The approval rate and odds ratio were analyzed with respect to the general characteristics, past medical history and work-related information using a logistical regression and Student t-test. RESULTS: Of the 1046 selected cases, the approval rate was 18.5%(194 cases). In the multivariate logistical regression analysis, the factors for approving cerebrovascular disorders and cardiovascular diseases as work-related diseases were found to be the average working time over the last 1 week, occupational category, gender, age, death or survival, the presence of an associated disease, claimed province, and smoking. CONCLUSION: Factors for approving claims of cerebrovascular disorders and cardiovascular diseases as work-related diseases were the average working time over last 1 week, gender, age, death or survival, claimed disease, presence of associated disease, claimed province, smoking.

Clinical education is difficult for actual practice of medical students. In particular, the practice in the field of obstetrics is more difficult to many students. Moreover, the education of sub-fields of obstetrics such as birth or abortion needs many materials of women's reproductive organs. However, the ordinary paper-based textbooks have some limitations for clinical education of obstetrics. The electronic textbook system based on multimedia data enables that many student, doctor, and public user overcome these difficulties, as a computer assisted learning. We developed multimedia database system which is connected with web using ODBC(Open DataBase Connectivity)and ASP(Active Server Page)/IDC(Internet DataBase Connection). Many text and multimedia data are gathered in the database. This system serves various multimedia data using internet and intranet in the student's class or home. In conclusion, providing multimedia data of obstetrics using ODBC, ASP/IDC method reduce the limitation of clinical education. This model of the electronic textbook would be a reference to develop multimedia database on the network.
