Neuromuscular disorders are common causes of weakness and hypotonia in the infantile period and in childhood. Accurate diagnosis of specific neuromuscular disorders depends first on identification of which aspect of the peripheral neuromuscular system is affected-the motor neuron in the spinal cord, the nerve root or peripheral nerve, the neuromuscular junction, or the muscle-and then on the determination of the etiology and specific clinical entity. Spinal muscular atrophy(SMA) is the most common autosomal-recessive genetic disorder lethal to infants. The three major childhood-onset forms of SMA are now usually called type I, type II and typeⅢ. Progression of the disease is due to loss of anterior horn cells, thought to be caused by apoptosis. Diagnosis is based on the course of the illness, as well as certain changes seen on nerve and muscle biopsy and electrodiagnostic studies. More recently, our understanding of the genetics of this disorder has provided a noninvasive approach to diagnosis. We report on a 3-year-old male patient with spinal muscular atrophy type II. He had progressive muscular weakness since 18 months of age. The upper arms were slightly, and the thighs moderately atrophic. There was muscle weakness of both the upper and lower limbs, being more proximal in distribution. Electromyogram revealed a neurogenic pattern.

Objectives : The purpose of this study was to investigate the change of posture balance and muscular strength before and after exercise by conducting a health gymnastics program for the elderly with chronic diseases of musculoskeletal system. Methods : The subjects of this study were 32 elderly people who had no experience participating in the musculoskeletal system linkage gymnastics program over 65 years old in a rural area in H city, Gyeonggi-do. The data were analyzed by computerized processing with SPSS 23.0. Results : The results of the study were as follows: First, the average of muscular strength before and after gymnastics according to general characteristics was significant in average according to age, presence of spouse, education level, and cohabitation type. Second, the subjects exercised for 2 days a week, and 25.59(±0.51) minutes on average. Third, the change of balance of the face (t=2.993, p=.011), shoulder (t=3.811, p=.002) and pelvic left and right (t=3.584, p=.004) was statistically significant in the posture balance. Fourth, muscular strength was statistically significant in motor function of AMS, SMS, and FMS (p<0.001). Conclusion : Therefore, after applying the health gymnastics program, the improvement of posture balance and muscular strength of the elderly became apparent, so it is necessary to disseminate this gymnastics program. The health gymnastics program is expected to positively improve the quality of life for the elderly.

Various muscular flaps are used in oral and maxillofacial reconstructive surgery for the defects caused by tumor resection and trauma or for the correction of head and neck deformities. The sternocleidomastoid(SCM) muscle may be widely used as a muscular or myocutaneous flap in these lesion. The authors used SCM muscular flap for the expected parotid defect following benign tumor related conservative parotidectomy in three cases. We expected that prevention of post-operative facial deformity, reduction of dead-space and protection of denuded facial nerve etc. is lead by SCM muscular flap. But the total SCM flap can lead to some complications such as "flat neck deformity", limitation of neck movement and overcontouring of parotid defect. Therefore, the authors used split pedicled SCM muscular flap and it lead good favorable results of post-operative functional and esthetic problems.

Purpose : The purpose of this study was to evaluate the effectiveness and analyse the change on muscular strength and exercise performance ability of university students participating in leisure sports by elastic-band exercise program. Method : The subjects(N=22) participating in leisure sports are recruited from K university located in Chungbuk. The subjects which are divided to 2 groups as experimental group(N=11) conducted elastic-band exercise program and control group(N=11) conducted stretching program. The muscular strength and exercise performance ability were measured before and after intervention. Result : There were no significant differences(p>.05) in sex, age, height, and weight among subjects. In the measurement of muscular strength, a significant difference(p<.05) was observed in each group, and there was also significant difference(p<.05) between two groups except gastrocnemius(p>.05). A significant difference(p<.05) in muscular volume was observed in each group, and there was also significant difference(p<.05) between two groups apart from gastrocnemius(p>.05). In exercise performance ability, there was significant difference(p<.05) in sergent jump and side-step in each group, and there was a significant difference(p<.05) between two groups in sergent jump, but there was no significant difference(p>0.5) in side-step. Conclusion : Based on this study, through a variety of age and various intervention period to apply more subjects conducting elastic-band exercise program should continue.

The purpose of this study is to analyze the correlation between the stature and the muscle performance ratings and the subjective discomfort rations at performing lower arm's pronation and supination according to change sin the height of working table for more efficient performance at designing a working table and performing a work. For the purpose, this study conducted an experiment targeting 40 people in their 20s, who were classified into 4 groups each group composing 10 people at intervals of 5cm from the standard stature of 166.5cm. The experiment measured the maximum isometric pronation and the supination muscular power, and at measuring the factors, the heights of working tables were set as 800mm, 850mm, and 900mm. From the measurement results, it was found that the stature and the maximum muscular power was correlated. That is, as the experiment groups's average stature is higher, the maximum muscular power was higher. For the correlation between the motion patterns(pronation and supination) and the maximum muscular power, it was seen that the maximum muscular power was higher at performing the pronation than the supination. In the correlation between motion patterns and the subjective discomfort ratings, it was seen that the subjective discomfort rating was higher at performing the supination than the pronation. For the correlation between height adjustment and the subjective discomfort ratings, as the height of working table was lower, the subject discomfort rating was lower. Therefore there was no difference in the maximum muscular power according to the height changes of working table, but it was found that as the working table was higher, the user felt more comfortable.

Purpose : This study aimed to introduce a 12-week muscular endurance exercise program and β-glucan consumption to obese elderly people with sarcopenia. We evaluated the program's impact on appendicular skeletal muscle strength and function, muscle function-related physical strength, blood lipids, and IGF-1. The results will serve as foundational data for preventing and improving sarcopenia. Methods : Forty elderly people aged 65 or older were recruited and underwent dual-energy X-ray absorptiometry. Based on criteria related to appendicular skeletal muscle mass (ASM/Height2: less than 5.4 kg/m2) and body fat percentage (at least 30% for women and 25% for men), we selected 24 obese elderly people with sarcopenia and excluded 56 who did not meet the criteria. Variables related to sarcopenia, blood lipids, IGF-1, and muscle function were measured before the 12-week muscular endurance exercise program. Results : In sarcopenic obese elderly participants, the 12-week muscular endurance exercise program significantly increased bone density and muscle mass while decreasing fat mass and percentage (p<.05). This program also improved grip strength, static balance, and SPPB in sarcopenic obese older adults. Furthermore, their 6-minute walk distance significantly increased (p<.05). Conclusion : Muscular endurance exercises combined with supplement intake can increase appendicular skeletal muscle and improve muscle strength and function, thereby improving the daily physical performance of the elderly.
