[Show abstract][Hide abstract] ABSTRACT: [Purpose] The purpose of this study was to investigate balance among elderly subjects with type 2 diabetes. [Subjects and Methods] Twelve subjects with type 2 diabetes and 15 age-matched controls were examined. Balance was assessed by a computerized device while the subjects were standing. [Results] Subjects with diabetes exhibited signiﬁcantly more sway than control subjects while standing on a balance platform. [Conclusion] Our findings suggest that diabetes impairs balance when compared with that in normal elderly subjects.
[Show abstract][Hide abstract] ABSTRACT: Abstract The purpose of this study was to investigate the effect of circuit exercise training and detraining, which is defined by termination of training without additional physical activities, in type 2 diabetic patients. Elderly with type 2 diabetes were divided into a group that exercised for 1 h three times a week for 12 weeks, followed by detraining for 8 weeks, or into a control group. Muscular strength, endurance, flexibility, agility, balance, body mass index (BMI), glycosylated hemoglobin (HbA1c), and blood lipid profile were measured. Of the 98 diabetic participants who joined this study, 37 patients completed the program (exercise group = 24, control group = 13). After training, muscular strength, flexibility, balance, agility, and endurance in the training group were significantly higher than at baseline and compared to the control group. HbA1c levels decreased in the training group. There was no significant improvement in BMI and blood lipid profile in either group. Flexibility and agility in the training group declined significantly after detraining. In spite of this decline, flexibility and agility were significantly higher compared to the baseline and to the control group. In type 2 diabetic patients, circuit training had a beneficial effect on the indices of physical function and glucose metabolism. Training resulted in good improvement; and during detraining, the effect of exercise training was maintained except in some parameters.
[Show abstract][Hide abstract] ABSTRACT: [Purpose] Aging is associated with a progressive decline in overall muscle strength. Loss of lower limb strength leads to an increased risk of falls and a sedentary lifestyle. The purpose of this study was to investigate whether lower limb strengthening exercise leads to improved lower limb strength and balance function for the elderly. [Subjects] From a total of 74 respondents, 50 subjects were randomly assigned to either a training group (n = 30) or a control group (n = 20). The subjects ranged in age from 65 to 82 years. A randomized controlled trial compared the effects of strengthening exercise and balance function. [Methods] Leg extension and lower curl exercises were performed during the 12-week study. [Results] After training, the lower limb strength and balance of the individuals in the training group had significantly improved compared to the baseline. [Conclusion] Improvement in lower limb strength may lead to balance enhancement in neurologically intact older persons.
[Show abstract][Hide abstract] ABSTRACT: [Purpose] The purpose of this study was to compare the gait parameters of age-matched people with a normal gait (≥ 65 years), age-matched people with knee pain, and age-matched people with walker dependent gait at a self-selected gait speed. [Methods] Subjects walked on even ground in bare feet and were allowed a natural arm swing on a 6-m walkway. Walker-dependent participants walked on a walkway without a walker. [Results] The kinematic and spatiotemporal gait characteristics were used to investigate the difference among the each group. Hip flexion, knee flexion, and stride width parameters were not different. The gait speed, stride length and time, hip and knee extension, and ankle flexion and extension parameters were significantly different. [Conclusion] A comparision of kinematic and spatiotemporal gait characteristics during gait may provide an insight into the gait pattern of normal elderly people, those with knee pain, and the walker-dependent elderly.
[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to verify the validation and usefulness of an online cognitive examination system to measure the degree of cognitive deficits of stroke patients. To verify the usefulness of the online examination system, thirty-one stroke patients and twenty normal, healthy volunteers as an age-matched control group were recruited. The thirty-one stroke patients were classified into three groups according to the severity of their cognitive dysfunction. To evaluate the reliability of the online system we compared the results of our system with the results of the Korean version of the Mini-Mental Status Examination (MMSE-K). There were significant correlations between the results of the evaluation by the online-based system and those of MMSE-K, and there were also significant differences between patient subgroups and the control group. We have investigated the usefulness of an online evaluation system and verified its effectiveness in the screening of patients for cognitive dysfunction.
[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to investigate clinical aspects of screen test tools for central neuropathic pain in thalamic stroke patients. Seven thalamic stroke patients were recruited as subjects. To classify the subjects into central neuropathic pain and non-neuropathic pain groups, the Leeds assessment of neuropathic symptoms and signs (LANSS) was used. Four patients were classified as having central neuropathic pain. To evaluate the central neuropathic pain, the quantitative somatosensory test, the median nerve somatosensory evoked potentials (SEPs), magnetic resonance imaging (MRI), and functional MRI (fMRI) were performed on average 31.5 months after stroke. The quantitative somatosensory test did not show a correlation between the central neuropathic pain group and the non-neuropathic pain group. The SEPs on the affected side showed a response in one of the patients without central neuropathic pain, and responses on the unaffected side were normal for all of the patients. MRI-based thalamic localization data indicate that this method is limited in its ability to distinguish the central neuropathic pain in thalamic stroke patients. Results of fMRI show that the secondary somatosensory areas of the central neuropathic pain group were more activated than those of non-neuropathic pain group. Based on the results, we verified that functional MRI is useful for evaluating the central neuropathic pain in thalamic stroke patients.
[Show abstract][Hide abstract] ABSTRACT: Congenital muscular torticollis, a common disorder that refers to the shortening of the sternocleidomastoid in infants, is sensitive to correction through physical therapy when treated early. If physical therapy is unsuccessful, surgery is required. In this study, we developed a support vector regression model for congenital muscular torticollis to investigate the prognosis of the physical therapy treatent in infants.
Fifty-nine infants with congenital muscular torticollis received physical therapy until the degree of neck tilt was less than 5°. After treatment, the mass diameter was reevaluated. Based on the data, a support vector regression model was applied to predict the prognoses.
10-, 20-, and 50-fold cross-tabulation analyses for the proposed model were conducted based on support vector regression and conventional multi-regression method based on least squares. The proposed methodbased on support vector regression was robust and enabled the effective analysis of even a small amount of data containing outliers.
The developed support vector regression model is an effective prognostic tool for infants with congenital muscular torticollis who receive physical therapy.
[Show abstract][Hide abstract] ABSTRACT: In clinical data minig, choosing the optimal subset of features is such important, not only to reduce the computational complexity but also to improve the usefulness of the model constructed from the given data. Moreover the threshold values (i.e., cut-off points) of selected features are used in a clinical decision criteria of experts for differential diagnosis of diseases. In this paper, we propose a fuzzy discretization approach, which is evaluated by measuring the degree of separation of redundant attribute values in overlapping region, based on spatial distribution of data with continuous attributes. The weighted average of the redundant attribute values is then used to determine the threshold value for each feature and rough set theory is utilized to select a subset of relevant features from the overall features. To verify the validity of the proposed method, we compared experimental results, which applied to classification problem using 668 patients with a chief complaint of dyspnea, based on three discretization methods (i.e., equal-width, equal-frequency, and entropy-based) and proposed discretization method. From the experimental results, we confirm that the discretization methods with fuzzy partition give better results in two evaluation measures, average classification accuracy and G-mean, than those with hard partition.
