In this paper, We investigated the characteristic analysis of flexibility and muscle strength for exercise to verify capacity in rehabilitation exercise of lumbar using lumbar strengthen exercise instrument. We have experiment in 20th years man and woman who are 20 subject with no medical history, we divided subjects into control group with no exercise and training group with lumbar strengthen exercise. We used Hi-Spine(Medicalscience.korea) also, provided exercise 40 minute a day, three days a week and progressed total four weeks. Moreover in our experiment, subjects exercised four postural position as lay down, sit, stand and stretch each ten minute. We measured trunk extension backward, trunk flexion forward, evaluation of based physical fitness and lumbar joint torque. The reults have shown that there more improved all for flexibility, based physical fitness and lumbar joint torque in training group than control group. We indicated that by rotating 3-D axis movement flatform of exercise instrument, muscle spindle in subject have been stimulated and these rotation direction and angle caused muscle tonus and contraction that makes muscle, flexibility and based physical fitness improve more. Our study can be used rehabilitation exercise program to aged people and patient with lumbar injury.

Purpose: The purpose of this study was to determine whether walking exercise improved physical function in elderly people using meta-analysis. Methods: Medical and nursing literature databases were searched to identify the studies on the effectiveness of walking exercise on physical function. In the databases, there were 16 articles reporting 21 interventions. Overall effect sizes for three outcome variables, elders' physical function in lower limb muscle endurance, whole body endurance and upper body flexibility, were calculated. Effects of study characteristics on outcome variables were analyzed. Results: The meta-analysis showed that walking exercise generally had positive effects on CST (chair stand test), 6MW (6 min walking), and SRT (standing or sitting reach test) with overall weighted effect sizes of 1.06, 0.41 and 0.29 respectively. This study also showed that the chronic disease status of the elders, intervention methods, and type of residence had different effects on CST, 6MW and SRT. Conclusion: The results indicate that walking exercise improves physical function in elders. Walking exercise which can be done at any time and any location is indeed a very effective exercise for elderly people.

Moyamoya disease is a disorder in which certain arteries in the brain are constricted. Blood flow can be blocked by the constriction and blood clots. The patients frequently experience transient ischemic attacks (TIA), cerebral hemorrhage, or may not experience any symptoms at all. It is reported that they have a higher risk of recurrent stroke and a distinct underlying pathophysiology. A 3-year-8-month old boy with moyamoya disease experienced cerebral infarctions five times, and he underwent a cerebrovascular anastomosis surgery four years ago. He showed swallow disturbance, general delayed development, hemiplegia, and strabismus. Also he had hypocalcified teeth with or without multiple caries lesions in all dentitions. Dental treatment under general anesthesia using sevoflurane was performed due to his lack of cooperation. Moyamoya disease is associated with various medical conditions requiring a thoughtful deliberation and a careful examination before and during dental treatment. Pain and anxiety control during dental treatment is important because hyperventilation induced by crying has been seen to trigger TIA. Both isoflurane and sevoflurane are commonly used in patients with MMD, but dynamic autoregulation is better preserved during sevoflurane than isoflurane anesthesia. So sevoflurance general anesthesia may be recommendable to manage dental patients having multiple caries with moyamoya disease.

The purpose of this study was to determine the effects of 12 weeks of WB-EMS training on body composition and heart rate variability based on BMI Level in Women. The subjects of the study were premenopausal women, and they were classified into the BMI-N(n=15) group for BMI<25, the BMI-1(n=16) group for BMI=25~29.9, and the BMI-2(n=9) group for BMI>30. And then, WB-EMS training was performed of 3 times a week for 12 weeks. Body composition and HRV were measured before and after the participation in exercise, which were subjected to a repeated-measures two-way ANOVA. In the case of a significant interaction between time and group, paired sample t-tests were conducted for a post-hoc analysis within each subject group. Tukey's method was used for post-hoc testing of differences between groups, and the significance level was set at 0.5. The results were as follows; First, The effect of WB-EMS training was found in all variables of body composition. In particular, Weight, BMI, FFM, and FM decreased the most in the BMI-2 group, followed by the BMI-1 and BMI-N groups. %BF and VF decreased the most in the BMI-2 group. Second, There was a difference in BPM in all groups, and the BMI-2 group showed the greatest decrease. There were differences in SDNN and RMSSD for each group, and there was no difference according to obesity level. There was no difference in LF, HF, and LF/HF ratio. In conclusion, it was confirmed that WB-EMS training can be an exercise therapy that has a positive effect on the body composition change and cardiac circulatory system in women with a high level of obesity.

Purpose: The authors used arthroscopy-assisted percutaneous reduction and cannulated screw fixation rather? than conventional arthrotomy for displaced glenoid fracture. Materials and Methods: We used arthroscopy assisted reduction and screw fixation for a 66 year old man who had a clavicle fracture, a displaced glenoid fracture and a scapula fracture. Results: At 9 months postoperatively, the patient had recovered full range of motion and was not inconvenienced by the surgery. Removal of the implant was done 12 months post-operatively under general anesthesia. Conclusion: The advantages of arthroscopy-assisted percutaneous screw fixation are less pain and less bleeding, shorter hospital stay and earlier rehabilitation. Arthroscopic percutaneous screw fixation for a displaced glenoid fracture seems to be a good alternative treatment method.

The aim of this study was to investigate the effect of resistance training with and without whole-body vibration(WBV) on the biomechanical properties of the plantarflexor in the elderly women (>60 yrs., n=35). Thirty-five volunteers were randomly assigned to a resistance training with WBV group (RVT, n=14), a resistance training without WBV (RT, n=11), and a non-training control group (CON, n=10). The RVT and the RT groups participated in the training sessions three times a week for 8 weeks, followed by a 4-week detraining period. The CON group was instructed to refrain from any type of resistance training. To assess strength and activation of the plantarflexor muscles, maximum isometric ankle plantarflexion torque and muscle activation of the triceps surae muscles were measured using dynamometry, twitch interpolation technique and electromyography at four different ankle joint angles. Also, the lower extremity function was assessed by vertical jumping. The measurements were performed prior to, 2 and 8 weeks after the training and after a 4-week detraining period. Following the 8-week training sessions, an increase in the isometric plantarflexion strength was found to be greater for the RVT compared with the RT group (p<.05). Muscle inhibition was significantly decreased after training than before training only for the RVT (p<.05). Following the detraining period, a decrease in isometric plantarflexors strength and a increases in muscle inhibition were significantly less in the RVT compared with the RT group. In conclusion, the exercise with WBV is a feasible training modality for the elderly and seems to have a boosting effect when used with conventional resistance training.
