The purpose of this review is to provide a comprehensive approach for optimal strategies of upperlimb motor rehabilitation after stroke. Stroke is a common, serious, and disabling global health-careproblem. Optimal organization of rehabilitation for stroke patients has been extensively documented. However, between 30% and 66% of individuals with stroke do not obtain satisfactory motor recoveryof the affected upper limb with rehabilitative interventions. The recovery of the affected upper extremitydepends on intensity, task progression, and repetition to neural plasticity, namely, the ability of centralnervous system cells to modify their structure and function in response to external stimuli. Recently,constraint-induced movement therapy, motor imagery, action observation, or mirror therapy has emergedas interesting options as add-on interventions to standard physical therapies. In this review, we willdiscuss to establish a framework by which several promising interventions for neural plasticity.

Aging affects metabolism, leading to physiological and functional impairments, and is also related to changes in body composition, including reduced skeletal muscle mass and increased body fat. These changes are correlated with the pathophysiology of sarcopenia, which is defined as age-related loss of skeletal muscle mass and strength. Low testosterone levels are associated with unfavorable body composition changes, and sex hormones decrease with aging. Androgen deficiency, along with lack of exercise and poor nutrition, may be among the modifiable contributors to sarcopenia. Testosterone treatment has been reported to have beneficial effects on muscle mass and function, but the results have been inconsistent. Here, we discuss the correlation between testosterone and muscle mass and function, the impact of testosterone on sarcopenia, and the probable mechanisms underlying these effects.

Background: Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) are simple, convenient, and non-in-vasive method to measure respiratory muscle strength at the mouth, but standards are not clearly established. This study was performed to obtain the normal predictive values of the MIP and MEP of Korean adult. Methods: Among 561 patients who visited clinic of family medicine in Pusan National University Hospital for health check, 107 people (62 men, 45 women) were recruited after excluding past history or underlying disease from December, 2010 to April, 2012. We measured MIP and MEP in sitting position using handheld respiratory pressure meter (MicroRPM, Micro Medical Ltd). Results: Mean values of MIP and MEP were 61.40±21.66 kPA and 71.73±17.91 kPA. Mean values of MIP and MEP of men according to age are as follows: 22men (30-39 years old), MIP=71.68±14.55 kPA and MEP=92.41±15.96 kPA; 19 men (40-49 years old), MIP=75.74±15.29 kPA and MEP=89.89±15.41 kPA; 21 men (50-59 years old), MIP=68.14±22.74 kPA and MEP=81.14±20.52 kPA. Mean values of MIP and MEP of women according to age are as follows: 19women (30-39 years old), MIP=52.37±21.20 kPA and MEP=57.89±15.91 kPA; 11women (40-49 years old), MIP=45.09±15.44 kPA and MEP=59.64±8.65 kPA; 15 women (50-59 years old), MIP=42.13±18.11 kPA and MEP=58.38±14.12 kPA. Conclusion: We report normal values of respiratory muscle strengths according to sex and age after measuring the MIP and MEP in healthy Korean adults.
분산전원 전력품질 모니터링 시스템을 위한 임베디드 하드웨어 테스트

When distributed powers are interconnected to the grid, lack of source stability may cause some events that should be measured and stored as soon as they occur. This paper presents a real-time hardware system that has been developed for quick and reliable monitoring of the distributed powers quality. The system is composed of a digital signal processor (MPC741O, Motorola) and a 16 bits A/D board (VMIVME3I22, GE). To guarantee the real time operation, it is based on a real time OS (VxWorks). Hardware tests of the embedded system have been made to check the performances of the proposed system. Test signals of several events are generated by using a LabView (hardware) system. The tests show that the system complies with the desired IEEE standard for power quality monitoring.
Cauda Equina Syndrome Caused by Spinal Dural Arteriovenous Fistula
신명준,Wan Kim,백승국,Soo Yeon Kim,Sung Nyun Kim 대한재활의학회 2011 Annals of Rehabilitation Medicine Vol.35 No.6
Spinal dural arteriovenous fistula (SDAVF) is rare but still the most commonly encountered vascular malformation of the spinal cord. A 31-year-old male developed gait disturbance due to weakness of his lower extremities,voiding diffi culty and sexual dysfunction with a progressive course since 3 months. He showed arefl exia in both knees and ankles. Electromyographic fi ndings were suggestive of multiple root lesions involving bilateral L2 to S4roots of moderate degree. Magnetic resonance images showed high signal intensity with an ill-defined margin in T2-weighted images and intensely enhanced by a contrast agent through the lumbosacral spinal cord. Selective spinal angiography confirmed a dural arteriovenous fistula with a nidus at the L2 vertebral level. After selective endovascular embolization, his symptoms drastically improved except sexual dysfunction. We report a rare case of cauda equina syndrome due to spinal arteriovenous fistula with drastic improvement after endovascular embolization.
