The ankle is a complex structure supporting the entire musculoskeletal system during standing and walking. And so the goals of operative treatment for ankle fractures are to obtain an anatomical reduction that is maintained by stable fixation, resulting in a healed fracture and recovery of normal function. The 64 patients who had ankle fractures were treated by arthroscopic reduction(20 cases) and open reduction (43 cases) in Konkuk university hospital from February 1991 to October 1997 and the results were analyzed in clinical and radiological aspects. The following results were obtained. According to the criteria of Meyer, arthroscopic assisted reduction group had good or excellent results in 18 cases (90%) and open reduction group good or excellent in 35 cases (83%). The difference of the results was not significant statistically, but arthroscopic assisted reduction technique has several advantages over open technique; the best assessment of articular surface, lower wound problem, postoperatively faster rate of rehabilitation and minor discomfort.

The purpose of this study was to investigate the different patterns of the lower limb between elderly and adult females to reduce the rate of falls. Ten old females(age: $73.1{\pm}2.69yrs$, height: $151.9{\pm}4.82cm$, mass: $57.36{\pm}5.36$) and ten adult females(age: $28\pm}4.76$ yrs, height: $160.6{\pm}6.83cm$, mass: $53.9{\pm}8.44$) were participated in this experiment. The gait motions were captured with Qualisys system and variables were calculated with Visual-3D. The following results were found. The elderly female group showed bigger inclination angle between COM and COP than the adult female group so that the dynamic stability was reduced in walking for the compensation with a bigger stride width. The elderly female group ensure for the necessary forward movement of COM in order to replace the decreased function of ankle and knee joint. If the distance between COM and COP is closer and the energy reduction of a specific joint is reduced, they could prevent the elderly female's falling rate by strengthening of muscles which were related the extension of ankle joint.

In this study, a transfemoral prosthesis system of which stance phase and swing phase are controlled during walking has been developed for the recovery of the biomechanical function of the amputated leg. It consists of a 5 bar link mechanism, a hydraulic-rubber knee damper for stance phase control and a pneumatic cylinder controlled via a microprocessor for stance phase control. The mechanical characteristics and behaviour of the knee damper which absorbs the impact energy generated at the heel contact was investigated. The characteristics of the pneumatic cylinder essential for the speed adaptation of the prosthesis during swing phase was also studied for its mechanical characteristics. The prosthesis was subject to the clinical test ant the gait characteristics obtained were very close to those of normal. The stance and swing controlled prosthesis that were developed in this study showed good stability during the stance phase and showed good controllability during the swing phase.

Mucopolysaccharidoses (MPSs) are a group of rare inherited metabolic diseases caused by deficiency of lysosomal enzymes. MPSs are clinically heterogeneous and characterized by progressive deterioration in visceral, skeletal and neurological functions. The aim of this article is to review the treatment of MPSs, the unmet needs of current treatments and vision for the future including recent clinical trials. Until recently, supportive care was the only option available for the management of MPSs. Hematopoietic stem cell transplantation (HSCT), another potentially curative treatment, is not routinely advocated in clinical practice due to its high risk profile and lack of evidence for efficacy. From the early 2000s, enzyme replacement therapy (ERT) was approved and available for the treatment of MPS I, II and VI. ERT is effective for the treatment of many somatic symptoms, particularly walking ability and respiratory function, and remains the mainstay of MPS treatment. However, no benefit was found in the neurological symptoms because the enzymes do not readily cross the blood-brain barrier (BBB). In recent years, intrathecal (IT) ERT, substrate reduction therapy (SRT) and gene therapy have been rapidly gaining greater recognition as potential therapeutic avenues. Although still under investigation, IT ERT, SRT and gene therapy are promising MPS treatments that may prevent the neurodegeneration not improved by ERT.

Purpose: The purpose of study was to measure stroke patients' ability to balance and their degrees of clinical function and to examine the effect of the aquatic exercise method using tasks related to these features. Methods: Twenty stroke patients were randomly assigned to an aquatic task exercise group and a land task exercise group. Both groups used the same exercise method for 60 minutes each session, three times a week for 12 weeks at the same time point and with the same amount of exercise. Results: Before and after the exercise, static balance was measured using balance measuring instruments locomotive faculties, muscular strength, and dynamic balance were assessed through the Berg balance and 10 m gait tests. Finally, gait abilities were measured, and the data obtained were analyzed to generate the results. Conclusion: Both groups showed significant improvement, but the aquatic exercise group showed slightly more significant results in static balance, Berg balance, and upright walking tests. It is thought that the improvement of stroke patients' balance and gait ability can be triggered through the application of aquatic exercise programs in the future.

Recently, Korea is constantly increasing its elderly care hospitals, and requires establishment of general evacuation plan considering old people's behavioral characteristics and physical states in emergency situations such as fire, and etc. In addition, because most of the facility users are patients under serious dementia and stroke, they feel difficulty evacuating by themselves, with differing evacuation time according to each walking status (bed, wheel chair, and various supplementary instruments), which is why it makes it difficult to have them all evacuate. This paper, in order to suggest data reference for designing on the basis of functionality, used various collected data utilizing Simulex to measure evacuation time through the model of elderly care hospital, a medical facility. During the study, several problems were found.

The purpose of this study was to investigate the effects of knee joint muscle fatigue and overweight on the angular displacement and moments of the lower limb joints during landing. Written informed consent forms, which were approved by the human subject research and review committee at Dong-A University, were provided to all subjects. The subjects who participated in this study were divided into 2 groups: a normal weight group and an overweight group, consisting of 15 young women each. The knee joint muscle fatigue during landing was found to increase the dynamic stability by minimizing the movements of the coronal and horizontal planes and maintaining a more neutral position to protect the knee. The effect of body weight during landing was better in the normal weight group than in the overweight group, with the lower limbs performing their shock-absorbing function in an efficient manner through increased sagittal movement. Therefore, accumulated fatigue of knee joint muscles or overweight may be highly correlated with the increase in the incidence of injury during landing after jumping, descending stairs, and downhill walking.

Background: Peripheral nerve injuries are a commonly-encountered clinical problem and often result in a chronic pain and severe functional deficits. Objectives: The aim of this study was to evaluate the effects of acupuncture on the descending pain and the recovery of the locomotor function that follows sciatic crushed nerve injury in rats. Method: In order to assess the effects of acupuncture on the descending pain and functional recovery, we investigated the walking track analysis, brain-derived neurotrophic factor (BDNF) and its receptor tyrosine receptor kinase B (TrkB) expression in the sciatic nerve, and on the expressions of c-Fos and nitric oxide synthase in the paraventricular nucleus (PVN) of the hypothalamus and in the ventrolateral periaqueductal gray (vlPAG) region resulting from sciatic crushed nerve injury in rats. Results: Acupuncture treatment at Huantiao (GB30), Yanglingquan (GB34), and Weizhong (BL40) facilitated functional recovery. C-Fos and nitric oxide synthase expressions in the brain and BDNF and TrkB expressions in the sciatic nerve were decreased by acupuncture treatment. The most potent effects of acupuncture were observed at the GB30 acupoint. Conclusion: It is possible that acupuncture can be used for pain control and functional recovery from sciatic nerve injury.

The purpose of this research were to evaluate the overall capacity of activity in hemiplegic patients caused by stroke, to learn the relationship of the overall capacity of activity with 8 out of 9 subtest of the Motor Assessment Scale (MAS) excluding general tonus subtest, and to use in creation of more efficient rehabilitation program by using Motor Assessment Scale (MAS). Twenty-four stroke patients (14 men and 10 women) were the subjects in this study. Their average age was 59.5 and they received average of 17.88 month of therapy. Collected data analysis was completed by using Statistic Analysis System (SAS). The results were as follows: 1) There was no difference in capacity of activity between right hemiplegia and left hemiplegia. 2) There was no difference in capacity of activity compared therapeutic period and age. 3) In comparing the relationship of the each subtest with the overall capacity of activity, upper arm function showed the highest relation (pearson's r = 0.914), and balance sitting (pearson's r= 0.812) and supine to sitting overside of bed (pearson'sr = 0.746) also showed large relationship. 4) Hand movement (pearson's r = -0.45) and advanced hand activity (pearson's r = -0.401) revealed relationship of general tonus with each subtest. 5) Supine to sitting over side of bed (pearson's r = 0.74), balanced sitting(pearson's r = 0.523), and sitting to standing (pearson's r = 0.723) showed large relationship with walking.
