Purpose: This study was done to report nursing case for ADL improvement of elders who have CVA(Cerebrovascular Accident) sequelae. Methods: The client had registered in the C visiting nursing center after being decided a long-term care Grade 2. Data were collected through consultation logs for recipients, Activities of Daily Living (ADL) records, fall risk assessment (Huhn) sheets, decubitus ulcer risk assessment (Braden Scale) sheets, cognition assessment (K-MMSE) sheets, long-term care benefit provision records, and interviews with visiting nurse. Data were collected and analyzed according to the Omaha System problem classification. The intervention scheme and the problem rating scale for performance were applied to present the case for home-visit nursing. Results: The client registered in August, 2018, was provided home-visit nursing care once a week as of September 2020. ADL, cognitive levels and decubitus ulcer risks were found to have improved. Conclusion: This case report presents the value of classifying nursing problems and checking nursing intervention provided to patients with problems of ADL. The presentation of home-visit nursing cases applying a standardized nursing problem classification scheme for clients with various problems showed that a high quality level of care is guaranteed and evidence-based nursing can be provided by visiting nurses.

The design of an air seat cushion for preventing decubitus ulcer includes many design factors such as the even distribution of interface pressure, the minimization of mean and peak interface pressure values, and the reduction of interface shear force and pressure gradient. It involves the anatomic condition of plegia's buttock as well as air pressure in air cells of cushion. As a result, a suitable design of the cushion satisfying the all requirements is a difficult problem. Therefore, an appropriate and effective numerical tool to develop an air cushion orthosis is required. The purpose of the present study was to develop an air seat cushion orthosis having optimized air cells for evenly distributed interface pressure between the buttock and cushion surface. For the purpose, an advanced finite element (FE) model for the design of air cushion was developed. Since the interface pressure and shear force behavior, as well as stress analyses were primary concern, a FE air cell model was developed and verified by the experiments. Then, the interactions of two cells were checked. Also, the human part of the developed numerical model includes every material property and geometry related to buttock and femoral parts. For construction of dimension data of buttock and femoral parts, CT scans were performed. A commercial FE program was employed for the simulation representing the seating process on the orthosis. Then, sensitive analyses were performed with varying design parameters. A set of optimal design parameters was found satisfying the design criteria of the orthosis. The results were utilized to produce a prototype of the orthosis. Experimentally, the buttock interface pressure distributions from the optimized and previous ones were compared. The new seat orthosis showed a significantly improved interface pressure characteristics compared to the most popular one in the market. The new orthosis will be used for the development of the AI(artificial intelligent) controlled seat orthosis fur prevention of decubitus ulcer fur various plegic patients and the elderly.

Thoracoscopic esophagectomy for esophageal cancer can be performed in multiple positions, such as the lateral decubitus position or prone position, using various techniques. Each approach has its own advantages and disadvantages, and surgeons can select an appropriate approach based on their preferences. Except for the reduction of pulmonary complications, the benefits of thoracoscopic esophagectomy, including oncologic outcomes, have not been proven scientifically. This review describes the approaches and procedures of thoracoscopic esophagectomy and presents scientific evidence for this procedure.

Pressure sore(decubitus ulcer) is the an ulceration and necrosis of the skin and underlying tissue usually occuring on a bony prominence of the body after prolonged or repeated pressure. This study was designed to evaluate the effects of an oriental medicine(Sipjeondaebo-tang) on pressure sores complicated by cerebrovascular diseases. Methods: As For treatment, we used Sipjeondaebo-tang. Results: Both patients were treated with Sipjeondaebo-tang. After treatment, the pressure sores of two patients were improved. Conclusions: This study suggests that Sipjeondaebo-tang is effective in treatment of pressure sores(decubitus ulcer) complicated by cerebrovascular diseases.

With the medical progress that has given spinal cord injured(SCI) individuals greater longevity and better overall health, chronic pain is emerged as major challenge in treating this population. According to past reports, estimates of prevalance of severe/disabling chronic pain in SCI patients have ranged from 18% to 63%. In etiologies of chronic pain in SCI patients, psychic or psychogenic pain categories should be included and more recent data have demonstrated that the persistant pain is directly related to higher levels of psychosocial distress and impairment. Recently, neurophysiological classification of the SCI pain syndrome into three etiologic groups(a; mechanical pain, b; radicular pain, c; deafferentation pain) is more frequently adopted for the classification of chronic SCI pain syndrome. The deafferentation pain is most common of the pain syndromes associated with SCI. After cervical epidural anesthesia for the surgical intervention of decubitus ulcer on the hip of two SCI patients, there were much reduction of existing chronic deafferentation character pain.

This paper proposes a new 75 fuzzy model approximation method which reduces error in nonlinear fuzzy model approximation over the V-type decision rules. Employing rational Bezier curves used in computer graphics to represent curves or surfaces, the proposed method approximates the decision rule by constructing a tractable linear equation in the highly non-linear fuzzy rule interval. This algorithm is applied to the self-adjusting air cushion for spinal cord injury patients to automatically distribute the patient's weight evenly and balanced to prevent decubitus. The simulation results indicate that the performance of the proposed method is bettor than that of the conventional TS Fuzzy model in terms of error and stability.

Functional electrical stimulation (FES) has developed over the last 35 years to become a scientifically, technologically and clinically recognized field of interest in clinical medicine. FES has been applied to locomotion, grasping, ventilation, incontinence, and decubitus healing. However, all of these achievements illustrate the initial applications of FES; its true potential has not yet been realized. Recently, FES systems, which are miniaturized stimulation devices, have been utilized in the clinical setting. However, because the stimulating electrodes of the current FES devices are percutaneous electrodes, which are susceptible to wire breakage, and skin infection an implantable FES stimulating electrode has been introduced in the U.S. and Japan. In the present study, an external power supply method using radio frequency (RF) coupling and data transmission was developed for the control of the implantable FES device. In addition, we review the current understanding of FES devices and their application in clinical medicine.

A finite element simulation model was developed for the performance optimization of a closed type air-cell mattress used for the ulcer prevention. An H-model with material properties of human flesh and kinematic joints were used for the calculation of the body contact pressure. The material property of rubber air-cell was evaluated by tensile test of standard specimen. We evaluated the body contact pressure distribution after laying human model on the inflated air-cell mattress. It was found that the body contact pressure was dependent on cell height. but hardly affected by the thickness of the rubber in a cell.
