  • Long span structures with low natural frequencies such as shopping malls, large offices, and assembly rooms may experience signification dynamic responses due to human activities. In many cases, the group activities are common thing in comparison with the single activity. The purpose of this study is to evaluate the responses of building structure subjected to group human loads using mode shapes. For this purpose, equations to estimate the magnitudes ol responses ol structure subjected to group walking loads are derived. And the correlation of loads is verified for identifying the relation of each human load composing of group human loads using two load cells. The method is proposed for evaluating the responses of structure subjected to group loads using mode shapes and correlation function related to each human loads. The effectiveness ol the proposed method is verified analytically using a simple beam and floor and experimentally on a footbridge measuring the structural response induced by group pedestrians for the case of synchronization or not. Results indicate that the amplitudes of group walking loads can be easily estimated if the mode shapes are available, and that the corresponding structural responses can be estimated easily by the simple response measurement using the proposed method.

  • The purpose of this study was to analyse the gait characteristics of stroke patients walking on a Zebris system, through quantitative three-dimensional biomechanical analysis. They underwent a continuous rehabilitation training program (RTP). A comparison was made between 3 month and 6 month RTP participants. Their ages were between 60 and 65. The data were analyzed by t-test. The result of comparative analysis of the two groups can be summarized as below. Temporal-spatial data, sagittal plane angular kinematics data, and peak ground reaction force and max pressure data showed that there were no significant differences between the 3 month RTP group and the 6month RTP group (Table 2, Table3, Table 4). It can be suggested that patients with hemiplegia after stroke can improve their walking function through continuous RTP participation.

  • Objectives : Oriental Medicine Music Therapy is a new way of treating and preventing various diseases and promoting health by means of music specially picked and designed to produce Qi(氣) fitting to an individual person in the areas of the structure of human body, physiological function, pathological change, diagnosis and treatment. Therefore, it can facilitate the efficiency of the treatment much better and faster than only with herb or acupuncture. Equilibrium between body and mind is its originality. Methods : A 38-year old man came to hospital suffering from left side weakness, dysarthria because of cerebral infarction. After one week's medication in the part of neurology, he was sent to the oriental medicine music therapy center, and he took ten times' medical treatments once a day. Before and after the treatments, implementing 'Ink foot print analysis', as for the movement capacity and walking of left side weakness, these results are acquired. Results and Conclusions : 1. Before the oriental medicine music therapy, except the acceleration and deceleration section, within three meters, a right foot's step was measured 30.55 cm and a left foot was measured 15.2 cm, and the step distance was 15.2 cm. After the 10 times treatments, the right foot's step was 112.6 cm, the left foot's step was 113 cm, and the step distance improved to 51.8 cm. 2. The normal person's average step is about 38 cm, and it could be decreased owing to a decreptitude, pain, fatigue, and the weakness of the legs. In spite of all, from the increased 50 cm step measurement with the patient's body condition, it means that his movement capacity is recovered. 3. In the measurement of walking time, before 10 times treatments, it took 46.35 seconds within 6M, but after the treatments, it increased to 7.47 seconds as same as a normal person's walking speed. 4. In insomnia, and the abnormality of a facial muscle, it shows lots of improvement, and even the accuracy of a pronunciation, but despite of the 10 times treatments, the 'ㄹ(r)' sound placed under a vowel is unclear. 5. Before the 10 times' treatments, he can move the left side shoulder with pain and cannot move below the left elbow. After the treatments, the pain was disappeared, and he was able to move over 60 cm without pain. And improving of the movement of fingers, he can beat over 8 times with a drumstick.

  • This study was to determine the effect of 12-week balance training with visual feedback on balance and walking functions in patients with post-stroke hemiparesis. Twenty individuals with chronic stroke volunteered to participate in this study. They were randomly allocated to either experimental group (EG) or control group (CG), with 10 subjects in each group. Subjects from the group 1 underwent 15-min balance training with visual feedback and 15-min routine-scheduled physical therapy, and subjects from the group 2 performed 30-min routine-scheduled physical therapy only, which comprised mat exercise, strengthening, postural correction, and functional practice. Assessment tools were made with the Functional Reach Test (FRT), Timed Up and Go Test (TUGT), and 6 Min Walk Test (6MWT). In within-group comparison, the EG showed significant differences in all parameters (p<0.05), while significant differences were not found for the CG (p>0.05). In between-group comparison, the change values of the FRT and 6MWT appeared to be significantly greater for the EG than those of the CG (p<0.05). These findings suggest that balance training with visual feedback may be favorably used to improve balance and walking functions in patients with chronic post-stroke hemiparesis. Further studies with larger sample and long-term follow-up period need to generalize the results of this study.

  • Objectives: Parkinson's disease is the neurodegenerative disease that affects both motor and non-motor function, including postural instability. Camptocormia is an abnormal condition in which the thoracolumbar spine bends forward during walking or standing. However, the treatment options are limited and often not effective. The purpose of this study was to report on the Korean medical treatment of a Parkinson's disease patient with postural instability who presented with camptocormia. Methods: We used Korean medical treatment including herbal medicine (Jemageopung-tang), acupuncture and pharmacopuncture therapy to the patient who was admitted to the hospital for 21 days. The clinical symptoms were assessed with the Unified Parkinson's Disease Rating Scale (UPDRS) and walking time without assistance. Results: After treatment, the UPDRS Parts 2 and 3 scores were decreased from 5 to 3 and 20 to 9, respectively. Also, the walking time without assistance was improved. Conclusion: This study suggested that Korean medical treatment could be an effective option for treating Parkinson's disease with postural instability.

  • This study conducted a systematic review of evidence-based interventions to confirm the importance of gait in dementia patients and to inform the necessity of various interventions necessary for gait. Based on PRISMA's guidelines and evidence-based intervention, a systematic review were conducted, and papers published in domestic journals for the past 10years were collected, and the dependent variables measured along with the intervention type and gait were analyzed. For data search, research papers from January 2011 to June 2020 were collected through RISS, KISS, the National Library of Korea, and the Library of Congress. The main search terms were 'dementia patient', 'walking', and 'walking ability'. Searched 57 papers on dementia patients and gait that meet the literature selection criteria. Among them, papers overlapping with papers before 2010, papers whose dependent variable is not related to gait ability were excluded, and finally, other than dementia diseases. As for the type of gait intervention, there were many programs related to exercise such as fall prevention and physical activity, and the dependent variables measured along with gait were physically and psychologically diverse. Although domestic studies for dementia patients are conducted in a variety of directions and methods, there are few studies on the improvement of function and gait of the lower extremity part of the body. Therefore, it is necessary to study the multifaceted and various intervention methods for walking in dementia patients.

  • Objective : The purpose of this study was to analyze the effects of dual-task training on stroke patients. Methods : We searched the databases such as NDSL, RISS, PubMed, CoChrane and EMBASE for publications in the past decade. Finally, 10 papers were selected. Qualitative assessment was performed according to the traditional single-layer evidence model, and meta-analysis was performed using the Comprehensive Meta Analysis 3.0 program. Results : The quality level of each of the 10 selected papers all correspond to I and II in the traditional single-layer evidence model. The motor tasks that constitute dual-task training comprised walking or balancing tasks in 7 articles and the motor tasks related to upper extremity were selected in 3 studies. The effect sizes for ADL function and Cognitive function were 0.65 and 0.64 (medium size effect) respectively. Moreover, the effect sizes of Lower extremity and Upper extremity motor function were 0.34 and 0.22 (small size effect) respectively. The effect size of ADL function and Cognitive function were statistically significant p<0.05). Conclusion : This study confirmed that dual-ask training can be a useful intervention technique for recovering a stroke patient's ability to perform daily activities and cognitive functions. This could be used as a helpful data when selecting appropriate intervention for stroke patients in the clinical setting.

  • Functional recovery of cerebrovascular accident (CVA) patients were studied by examining functional independence measure (FIM) to evaluate the functional state of the patients at admission to and at discharge from the hospital and its relationship with the family support. Study subjects consisted of 129 CVA patients, who were admitted and received rehabilitation treatment at K Medical Center of Oriental Medicine from August 3 to December 18, 1997. The results were as follows: 1) Total FIM score was $72.37{\pm}25.16$ at admission and $101.67{\pm}22.13$ at discharge. The difference of average score was 29.30, which was statistically significant by paired t-test. 2) The largest difference between FIM scores at admission and at clischarge was observed in items of walking and wheel-chair riding, and the smallest clifference in items of social interaction. 3) The recovery was faster with motor function than with cognitive function, because the difference of FIM scores at admission and at discharge was much larger with motor function. 4) Recovery was better in groups under age 49 than in groups above age 70. Functional recorvery was prominent especially in groups with normal sensory state and speech functions, and groups without urinary incontinence. Recovery was less significantly in patients with paraplegic patients hospitalized longer than 2 months, patients with family all the time, and patients with CVA over 11 days. 5) We could not find any relationship between functional recovery and family support. FIM scores were lower in groups of old age(r=-0.325), long stayed in hospital (r=-0.426), and long period of time after the onset of disease(r= -0.339) with a reciprocal correlation between FIM scores and these parameters. 6) Stepwise multiple regression analysis was done to evaluate factors to affect the recovery from CVA. FIM score at admission could explain 51.2 % of the functional recovery. Important factors were periods of hospitalization, state of sensory function, age, and education (listed in decreasing order of importance). In total, they could explain 64.89% of the functional recovery. These results indicate that functional recovery of CVA patients, who were admitted to oriental medicine hospital for rehabilitation treatment, could be estimated by measuring FIM scores. Recovery was significantly better at discharge from the hospital than at admission and motor function recovery rate was much faster than that of cognitive function. 2. Recommendation Based on these results, we recommend following further studies. 1) Comparative study of recovery of motor function and of sensory function would be necessary by measuring FIM scores once a week to evaluate the recovery of CVA patients. 2) It would be interesting to see whether there is any difference of functional recovery between patients treated with either western medicine or oriental medicine. 3) Psychological factors affecting the recovery of CVA patients need to be studied.

  • This study is aimed to find out the effect of PAPS-D on physical fitness of developmental disabled students who participated of Inline skate program. The subject of this study was 10 middle and high school students diagnosed as developmental disability. The subject attended a total of 32 classes twice a week for 16 weeks and the class was 1 hour each time. Improvement of physical fitness was assessed based on PAPS-D program developed by the Department of Education science in 2016 except for obesity measurement; cardio pulmonary function (walking in 6 minutes), flexibility (seated forward bend, clasped hand behind the back), muscle function (sit-up) and agility (standing long jump). To find out the interaction between control group and experimental group, two-way repeated measure ANOVA was used. As a result, there was a statistically significant relation in cardio pulmonary function and agility but not in flexibility and muscle function. 3 variables (cardio pulmonary function, flexibility and muscle function) among 4 variables showed positive effect of Inline skate program on physical fitness while one variable which was agility showed decreased result in post-test. Based on the results of three variables that were found to have improved in the pre post-examination, the result of this study indicates positive effect of Inline skating program on physical fitness of developmentally disabled students.
