Amyotrophic Lateral Sclerosis(ALS) is a fatal neuromuscular disease characterized by progressive muscle weakness resulting in paralysis. ALS is characterized by both upper and lower motor neuron damage. Diagnostic tests include magnetic resonance imaging(MRI) electromyogram(EMG), muscle biopsy, and blood tests. In order for a definitive diagnosis of ALS to be made, damage must be evident in both upper and lower motor neurons. When three limbs are sufficiently affected, the diagnosis is ALS. There is no cure for ALS. We recently experienced one case of ALS, The patients was diagnosed as ALS by EMG and Symptoms. We diagnosed her as Wea jeung and treated by Herbal-medication based on the differentiation of symtoms. we report change of his symptoms through both western medical treatment and oriental medical treatment.

Background: Lumbar disc herniation (LDH) causes neurological symptoms by compression of the dura mater and nerve roots. Due to the changed in proprioception inputs that can result in abnormal postural pattern, delayed reaction time, and changed in deep tendon reflex. Objective: To investigate the effects of lumbar stabilization exercises on motor neuron excitability and neurological symptoms in patients with LDH. Design: Randomized Controlled Trial (single blind) Methods: Thirty patients with LDH were recruited; they were randomly divided into the balance center stabilization resistance exercise group (n=15) and the Nordic walking group (n=15). Each group underwent their corresponding 20-minute intervention once a day, four times a week, for four weeks. Participants' motor neuron excitability and low back pain were assessed before and after the four-week intervention. Results: There were significant differences in all variables within each group (p<.05). There were significant differences between the experimental and control groups in the changes of upper motor neuron excitability and pain (p<.05), but not in the changes of lower motor neuron excitability and Korean Oswestry Disability Index. Conclusion: Lumbar stabilization exercises utilizing concurrent contraction of deep and superficial muscles improved low back function in patients with LDH by lowering upper motor neuron excitability than compared to exercises actively moving the limbs. Lumbar stabilization exercises without pain have a positive impact on improving motor neuron excitability.

The purpose of this study was to compare the circumference and skinfold thickness of upper and lower limb and the leg strength of the casted limb with those of the normal limb after removal of a leg cast. The subjects for the study were orthopedic patients who had had long and short leg casts or splints due to tibial, fibulal, metatarsal, calcaneus fracture or ankle sprains. The subjects were divided into two groups, those who had the cast on for less than 40 days and those for over 41 days. Circumference and skinfold thickness of the upper and lower limb on the side on which the cast was ap-plied were compared with those of the contralateral side after removal of the cast. Circumference and skinfold thickness of the upper and lower limb, and leg strength for those in a cast for under 40 days were compared with those of over 41 days for both the side to which cast was applied and the contralateral side. Measurements were made after removal of the cast. Skinfold thickness was measured by fat caliper, circumference was measured by tape and lower extremity strength was determined with flat foot pressing on an electronic digital health meter in the sitting position. The results can be summarized as follows : 1. The circumference of the upper and lower leg on the side on which the cast was applied, when measured after the cast was removed, were significantly less than those of the normal side, 93.88%, 93.11% each. 2. Skinfold thickness of the quadriceps and gastrocnemius on the side on which the cast was applied were significantly less than those of the normal side when measured after removal of the cast, 85.98%, 82.85% respectively. 3. Leg strength on the side where the cast was applied was significantly 1ss than that on the normal side, 60.20%. 4. There was no difference in the circumference of upper and lower limbs, skinfold thickness or leg strength on the side where the cast was applied between the group which had the cast applied for under 40 days and the group that had it applied for over 41 days. 5. The circumference of the upper arm and lower leg on the normal side for the group that had the cast applied for over 41 days was significantly greater than the group that had the cast application for under 40 days. T ere was no difference between the two groups in the circumference of the forearm and upper leg, skinfold thickness and leg strength in the normal side. From these results, it may be concluded that muscle atrophy was apparent in the casted limb compared to the normal limb, and the circumference of the upper arm and lower leg, and leg strength on the normal side increased after removal of the cast in the group which had the cast on for more than 41 days.

For the purpose of disclosing the effects of progressive low intensity exercise on the activity of the elderly, questionnaire survey and physical fitness examination were performed on the subjects who were 65 years old or older. The subjects were assigned into two groups using paired matching on gender and age: experimental group (33 persons) and control groups (35 persons). The subjects in experimental group was put on the low intensity exercise program (exercising upper and lower limbs for 12 weeks using dumbbell and lead-packed weight). The results showed that the difference of physical and social behavior scores among activities before and after exercise were significantly higher in all variables of general characteristics, health habits and status, perception, and physical fitness. The findings of this research suggested that the progressive low intensity exercise improves the activities of the elderly, physical activity, self assessed activity, activities of daily living, instrumental activities of daily living, social behavior of the elderly be affected by general characteristics, health habits and status, perception, and physical fitness.

The goal of this study is to analysis natural frequency for different static postures of human leg. To perform this research human leg is modeled by multi-body modeling for the musculoskeletal system. This leg model has biarticular muscles which acting on two joints and the muscles represents some of the major muscles, such as hamstring, of the upper and lower limbs. To obtain each static equilibrium position energy method is employed and to analysis natural frequency linearization method for constrained mechanical system is employed. Static equilibrium position depends on some parameter or condition such as hamstring stiffness or external force. Making a change these parameter the aim of this research can be performed.

The purpose of this study was a motion analysis of proprioceptive neuromuscular facilitation patterns which is scapular and pelvis patterns, upper extremity patterns, lower extremity patterns, trunk patterns. The patterns combine motion in sagittal plane for flextion and extension, coronal or frontal plane for abduction and adduction, transverse plane for rotation. The patterns composed of mass movement pattern of the limbs and trunk muscles. Every pattern can change by changing the activity of the middle joint in the extremity patterns and changing the patient's positions.

Posture of the upper limbs in field works is known to be an important risk factor associated with CTD(Cumulative Trauma Disorders). In particular, uncomfortable posture and highly repetitive works in shipbuilding industry(for instance, sand blasting, grinding and blast painting, etc) made workers exposed to a great risk of injuries. The purpose of this paper is to analyze recruitment pattern of the muscles according to posture(joint angle displacement) during grinding. In this study, EMG signals of pectoralis major, latissimus dorsi, and posterior deltoid muscle were measured and analyzed from FlexComp EMG solution. And subjective ratings of perceived exertion were made using Borg's CR-10 rating scale.

Subclavian vein injuries occasionally occur as a sequela of penetrating trauma or vascular access, but have rarely been reported to occur after clavicle fracture. The subclavian vessels are mainly enclosed by the subclavius muscle, the first rib, and the costocoracoid ligament. Therefore, in such cases, subclavian vein injury is rare because of the strcutures surrounding the subclavian vessels. Nevertheless, subclavian vein injuries occasionally show thrombotic manifestations, and thrombosis of the upper limbs constitutes 1-4% of cases of total deep vein thrombosis. Furthermore, to the best of the authors' knowledge, although vessel injuries have been reported after clavicle or rib fractures and nerve injuries to regions such as the brachial plexus, no case involving delayed presentation of isolated subclavian vein stenosis after clavicle fracture due to blunt trauma has yet been reported.

This research utilized the psychophysical methodology, where secrw drivers are used, to determine the effects of i) the location and orientation of work objects, and ii) wearing gloves, on ratings of perceived exertion at various body parts. The validity of the psychophysical methodology in determining a preferred work pace was also studied. The subjects drove screws with a screw driver into thick wooden sheet at three vertical and three horizontal locations. They drove serews for 3 minutes at each location and assessed the condition using the psychophysical scale. The results showed that only the vertical location was a significant factor in determining the discomfort ratings. Driving screws at elbow height on the vertical surface and with the lower arm close to the body on the horizontal surface were the work locations with the smallest ratings of perceived discomfort. Wearing gloves had significant effects on reducing the pain of the hand. From the experiment in which a comfortable work pace was identified using 20 minute psychophysical adjustment, it was found that the psychophysical method is sensitive to workers perception of the physical stress when the upper limbs are employed. This was confirmend by the high correlation between the psychophysical results and EMG measurement.
