The purpose of this study was to investigate the effect of balance training with upper extremity exercise on the improvement of balance performance in people who have had a stroke. Eighteen candidates who have all experienced a stroke, were living in Dong-Gu, Ulsan and were participating in a community based rehabilitation program, have been included in this study. The program was conducted three times weekly, 1 hour per session, for 7 consecutive weeks. Subjects were tested with 7 m and 100 m Timed Gait Test (sec), Timed Get Up and Go Test (sec), Functional Reach Test (cm) and 5 items of Berg's Balance Test at pre-training and post-training. Total balance index and balance ratios were measured by K.A.T. 3000. The balance training program performed by sitting on a chair and gymnastic ball and standing on stable and unstable surfaces during upper extremity exercises such as Proprioceptive Neuromuscular Facilitation (PNF) upper extremity pattern, picking a ball up from floor, throwing and catching it. After seven weekends of balance training, subjects showed a significant difference in balance test results. The exceptions were three items of Berg's Balance Test (p<.05). Balance index score and affected and unaffected side balance ratio had a larger improvement than pre-training (p<.05). The result of this study showed that intervention of this balance training program could improve the balance performance in people who have had a stroke.

Background: Hallux valgus (HV) is a foot deformity developed by mediolateral deviation of the first metatarsophalangeal joint. Although various foot-toe orthoses were used to correct the HV angle, verification of the effects of kinetics variables such as ground reaction force (GRF) through three-dimensional (3D) gait analysis according to the various type of orthoses for HV is insufficient. Objects: This study aimed to investigate the effect of soft and hard types of foot and toe orthoses to correct HV deformity on the GRF in individuals with HV using 3D motion analysis system during walking. Methods: Twenty-six subjects participated in the experiment. Participants had HV angle of more than 15° in both feet. Two force platforms were used to obtain 3D GRF data for both feet and a 3D motion capture system with six infrared cameras was used to measure exact stance phase point such as heel strike or toe off period. Total walk trials of each participant were 8 to 10, the walkway length was 6 m. Two-way repeated measures ANOVA was used to determine the effects of each orthosis condition on the various GRF values. Results: The late anteroposterior maximal force and a first vertical peak force of the GRF showed that the hard type orthosis condition significantly increased GRF compared to the other orthosis conditions (p < 0.05). Conclusion: There were significant effects in GRF values when wearing the hard type foot orthosis. However, the hard type foot orthosis was uncomfortable to wear during walking. Therefore, it is necessary to develop a new foot-toe orthosis that can compensate for these disadvantages.

Angiostrongylus cantonensis invades the central nervous system (CNS) of humans to induce eosinophilic meningitis and meningoencephalitis and leads to persistent headache, cognitive dysfunction, and ataxic gait. Infected mice (nonpermissive host), admittedly, suffer more serious pathological injuries than rats (permissive host). However, the pathological basis of these manifestations is incompletely elucidated. In this study, the behavioral test, histological and immunohistochemical techniques, and analysis of apoptotic gene expression, especially caspase-3, were conducted. The movement and motor coordination were investigated at week 2 post infection (PI) and week 3 PI in mice and rats, respectively. The cognitive impairs could be found in mice at week 2 PI but not in rats. The plaque-like lesion, perivascular cuffing of inflammatory cells, and dilated vessels within the cerebral cortex and hippocampus were more serious in mice than in rats at week 3 PI. Transcriptomic analysis showed activated extrinsic apoptotic pathway through increased expression of TNFR1 and caspase-8 in mice CNS. Immunohistochemical and double-labeling for NeuN and caspase-3 indicated the dramatically increased expression of caspase-3 in neuron of the cerebral cortex and hippocampus in mice but not in rats. Furthermore, western-blotting results showed high expression of cleaved caspase-3 proteins in mice but relatively low expression in rats. Thus, extrinsic apoptotic pathway participated in neuronal apoptosis might be the pathological basis of distinct behavioral dysfunctions in rodents with A. cantonensis infection. It provides the evidences of a primary molecular mechanism for the behavioral dysfunction and paves the ways to clinical diagnosis and therapy for A. cantonensis infection.

In this study, new design method of prosthetic foot was suggested which can evaluate the performance of prosthetic foot by implementing amputee's gait simulation using the finite element analysis. The basic shape of ESPF(Energy Storing Prosthetic Foot) was designed which is suitable for the below-knee amputee considering mechanical properties and kinematic properties. And, the performance evaluations were performed using the Taguchi method with orthogonal array L25. As a result, average main effect of factors for the ESPF's performance were calculated and then optimum condition of given shape was selected. Essential particulars for the performance evaluation from the simulation result were the quantity of external work needed in stance phase, the quantity of transferred energy from the ESPF through the knee, and the vertical displacement of knee at toe-off. Reasonable optimum condition was obtained from the using performance index. From this study, it was found that it is necessary for the design of ESPF to consider the geometrical data related to the magnitude of load on elastic material.

Purpose: Patients with Parkinson's disease suffer many restrictions in daily life. This case report investigated how intervention with proprioceptive neuromuscular facilitation (PNF)-based physical therapy can affect the activities of Parkinson's patients. Methods: The subject was a 67-year-old female patient diagnosed with Parkinson's disease 3 years ago. Since the last five months, overall activities have become difficult for her, and she finally visited a hospital to take outpatient physical therapy because of the gait difficulties she suffered. The patient's medical history, system review, body structure and function, and activities were evaluated. The patient had difficulties in activities such as lying down, sitting, standing, maintaining a standing position, and walking. The PNF-based intervention was used for treating the impairments and improving the activities. The intervention was performed for 30 min a day, three times a week, for eight weeks. The qualifier of the international classification of functioning, disability, and health was used to measure the result, and the measurement was conducted before and after the intervention for eight weeks. Results: According to the result, the scores for maintaining a standing position, moving around within the home, and going to the toilet improved to "no problem" from "moderate problem." The scores for shifting the body's center of gravity, walking short distances, and washing oneself improved from "moderate problem" to "mild problem." The scores for sitting and standing improved to "no problem" and "mild problem" from "complete problem." The scores for preparing meals and doing housework improved from "severe problems" to "mild problem" or "moderate problem." The scores for walking long distances, moving around outside the home and other buildings, and using transportation did not show significant changes. Conclusion: Intervention with PNF-based physical therapy improved the activity of patients with Parkinson's disease, thus proving its effectiveness. The case report suggested that a therapist can use PNF as a physical therapy intervention for patients with Parkinson's who suffered restrictions in daily activities.

Purpose: The purpose of this study was to investigate the effects of coordinative locomotor training (CLT) on the foot pressure and balance of patients with scoliosis. Methods: This was a single-case A-B-A study involving two patients with scoliosis. The study was designed to perform repeated measurements as follows: 5 times at baseline (A), 10 times during intervention (B), and 5 times after intervention (A). The study period was 5 weeks, and the CLT program was divided into warm up, CLT program, and cool down stages, at 50 min per stage. For the primary outcome measure, Gait View AFA-50 was used to determine the foot pressure and balance ability. For the secondary outcome measure, the SRS-22 questionnaire was used to assess the quality of life of the patients with scoliosis. Descriptive statistics and visual analysis using graphs were used to compare the rates of change. Results: The results of this study showed that the foot pressure and balance ability of the two subjects improved during the intervention period and remained improved even during the baseline period. However, their quality of life did not change after the intervention. Conclusion: CLT may have a positive effect on foot pressure and balance ability in patients with scoliosis. Also, this body function improvement may have positive effects on the performance of daily activities which employ the upright position.
