Objective : This study aims to examine how lumbar stabilization exercise and resistive exercise affect lumbar and lower extremity muscular strength of the aged. Method : Randomly selected 15 female senior citizens aged 65 or older at S, Y, and J senior citizens' center located in D city who meet the requirements for the study were divided into a resistive exercise group of 7 and a stabilization exercise group of 8 for which 60-minute-exercise sessions were administered three times a week for 12 weeks. Measuring lumbar and lower extremity muscular strength was measured six weeks and 12 weeks after exercise, respectively. Results : First, both resistive exercises and stabilization exercises are effective to improve lumbar muscular strength. Second, resistive exercise is effective to improve flexural muscle strength as well as lower extremity muscular strength, and stabilization exercise is effective for both flexion and extensor muscle strength. Conclusion : The 12 week lumbar stabilization exercise program appeared to be effective to improve lumbar and lower extremity muscular strength of the aged. This indicates that applying this program to identify and prevent frequent risk factors of falling can lead to the prevention of secondary problem factors of falling accidents.

Knee osteoarthritis is one of the most prevalent arthritis that weakens the muscles. This study focused on evaluating muscular functionality of knee osteoarthritis subjects. Muscular strengths of muscles around knee and hip joints of middle-aged female subjects aged over 40 suffering from knee osteoarthritis were evaluated by isokinetic dynanometer. Also, relation between the observed muscle imbalance in knee and hip joints and visual analogue scale was investigated. Subjects performed 8-weeks exercise on weakened muscles - particularly on knee extensors and hip abductors - and had their isokinetic muscular functionalities analyzed again. After the 8-weeks exercise, subjects' thigh circumferences were increased, accompanied with muscular strength improvements and decrease in visual analogue scale. Hence we emphasize the importance of exercise for muscular strength enhancement of knee extensors and hip abductors, in rehabilitation programs for knee osteoarthritis.

Objectives : The purpose of this study is to report on the improvement of respiratory function of a fascioscapulohumeral muscular dystrophy patient after receiving Korean medical treatment. Methods : This study was carried out on a 60 year-old male patient who suffered from fascioscapulohumeral muscular dystrophy. While we carried out Korean medical treatment, we observed $EtCO_2$ (end-tidal carbon dioxide), Vte (exhaled tidal volume) and PIP (peak inspiratory pressure). Results : $EtCO_2$ count decreased from 34 mmHg to 24 mmHg during the treatment period, and PIP count became stable. Vte count also did not worsen in this study. Conclusions : Based on this study, we concluded that Korean medical treatment could be effective in treating fascioscapulohumeral muscular dystrophy patients with respiratory failure.

Background: The purpose of this study was to investigate the effects of lumbar stabilization exercise with neurodynamic techniques on lumbar muscular strength and Oswestry index in lumbar disc herniation patient. Method: The Lumbar stabilization exercise with neurodynamic techniques was performed by 30 pt's in G hospital. The subjects were randomly organized into a study group 15 and control group 15. The exercises and neurodynamic technique were conducted for 40 minutes and, 3 times a week (total 24 times for 8 weeks). General characteristics of the Lumbar muscular strength and Oswestry disability index (ODI) were measured before the training and at 4 weeks and 8 weeks after the intervention. Comparison of the time dependent variable for each group was Calculated by a one way repeated analysis of variance (ANOVA). Comparison between the two groups was Calculated by an analysis of covariance (ANCOVA). Result: There was a significant difference in the Lumbar muscular strength and ODI (p<.05). Similarly in the inter-group analysis, significant differences (p<.05) occurred. Conclusion: In this study, we demonstrated that lumbar stabilization exercises with neurodynamic techniques are an effective therapy for Lumbar muscular strength and ODI in lumbar disc herniation patient's.

Dystrophinopathy, caused by mutations in the DMD gene, presents with variable clinical phenotypes ranging from the severe Duchenne muscular dystrophy (DMD) to the milder Becker muscular dystrophy(BMD) forms. DMD is a recessive X-linked form of muscular dystrophy. Two-thirds of mothers of affected males are thought to be DMD carriers. Approximately 2.5-7.8% of female DMD carriers have muscle weakness and are categorized as manifesting DMD carriers. The symptoms of female carriers of DMD range from mild muscle weakness to severe gait problems. The most commonly presented symptom is mild proximal muscle weakness, which is often asymmetric and progressive, but shows variable clinical spectrum with BMD of more severe DMD-like phenotype. Atypical presentations in manifesting carriers are myalgia or cramps without limb weakness, isolated cardiomyopathy and camptocormia. Multiplex PCR and MLPA analysis are common techniques to identify mutations in the DMD gene. Relationship between X-chromosome inactivation and clinical severity is not clear. Female carriers of DMD are not less common, and they have an important role of birth of a male DMD.

In this paper, capture motion and visual information from a virtual reality luge simulator to analyze muscular activity in the lower limbs. The Luge Simulator consists of a motion platform with a pneumatic module for weight distribution. We recruited luge athletes and healthy subjects and made real-time surface EMG measurements to estimate the muscular activity in the lower limbs according to the motion protocol of a simulator, and a test was conducted for each subject. The results indicated that the rectus femoris had the highest muscular activity according to the level of the slope and velocity of the luge. The soleus muscle showed a high level of activity during a turn in the luge according to the direction. We found that the development of a virtual reality sports simulator based on physical reaction results could bring positive effects to optimize reality and human cenesthesia.

Objectives : This study was carried out to investigate the correlation of meridian system in oriental medicine and muscular system in western medicine. Methods : Muscles were assigned to meridians by their main functions and the acupoints on them. New mutual relationships between meridians in lower limb were studied based on the muscular function. Results : In gluteal & femoral region, iliopsoas & quadratus femoris are assigned to spleen & stomach meridians, gluteus maximus & hamstrings to urinary bladder & kidney meridians, adductor muscle groups to liver meridian, gluteus medius & minimus & iliotibial tract to gall bladder meridian. In crural region, anterior crural muscles are assigned to stomach meridian, lateral crural muscles to gall bladder meridian, suferficial posterior crural muscles to urinary bladder (& kidney) meridian, deep posterior crural muscles to liver, spleen, kidney meridians. In lower limb, urinary bladder meridian and stomach meridian lead the muscular functions and correspond to each other, while spleen meridian assists stomach meridian, and kidney meridian assists urinary bladder meridian. Conclusions : Muscles may be assigned to meridians by their functions and the acupoints on them. From the view of muscular function, Yang meridians lead Yin meridians in lower limb.
