PURPOSE: This study compared cognitive task-directed functional motor control ability for reaching and kicking movements in younger and older adults. METHODS: Subjects were divided into two groups of younger and older adults, with 13 subjects in each group. Subjects were required to perform a dual task combining a functional movement and cognitive component. The task consisted of reaching and kicking movements. Participants performed indicated movements when a target appeared on a monitor. The target randomly appeared on the monitor every 10 seconds. The total performance time (TPT), joint angular velocity (JAV), and muscle activation time were used to evaluate motor control ability. RESULTS: There were significant differences in all evaluation factors in a comparison of younger and older adults (p<.05). TPT was significantly shorter in older adults, and JAV and muscle activation time were significantly slower than that in the younger adult group. Although the results for older adults were within the normal range for functional assessment, their motor control abilities were significantly worse for cognitive tasks compared with those of younger adults. CONCLUSION: The results of this study indicated that a motor control assessment tool using a cognitive task would be helpful in assessment of motor control ability in healthy older adults.

Purpose: The purpose of this study was to describe the functional (mobility, self-care, social ability) and health-related quality of life in children with cerebral palsy (CP). Methods: A cross- sectional survey of 202 children with CP, mean age $5.91{\pm}1.57$ years, was carried out using the Gross Motor Function Classification System (GMFCS), Gross Motor Function Measure (GMFM), Pediatric Evaluation of Disability Inventory (PEDI), and Child Health Questionnaire (CHQ). Results: The functional assessment of children with CP showed that a more severe GMFCS level was associated with lower functional abilities (p<0.05). The health-related quality of life assessment showed that psychosocial well-being was less impaired than physical well-being. The internal consistency of the three instruments was satisfactory (cronbach's ${\alpha}$>0.80). The three different scales were correlated from moderate to strong (r=0.44 to 0.92). It was also found that mobility, tone distribution, and the parents' education level exerted a significant effect on the quality of life of children with CP (p<0.05). Conclusion: These findings suggest that children with CP have reduced function and quality of life and these are influenced by various factors. However, planning and application of various task-oriented functional interventions to childhood CP may be useful.

PURPOSE: This study was conducted to determine if the Harrison hip score (HHS), a tool for assessing hip joint function, and the Burg balance scale (BBS), a general balance assessment tool, actually reflect the balance ability of total hip arthroplasty (THA) patients 3 months after surgery. In addition, this study investigated the initial weight distribution strategy for bilateral lower extremity after THA surgery to understand the balance of THA patients. METHODS: Fourteen 3-month THA patients performed static dual standing and sit-to-stand (STS) tasks. Ground reaction forces on each leg were collected to calculate the weight distribution symmetricity (SWD), and the HHS, functional HHS (f-HHS), and BBS were evaluated. Correlation analyses between SWD and the HHS (also f-HHS) and BBS were then applied to the THA patients. RESULTS: The correlations between functional evaluation tools (HHS, f-HHS, BBS) and SWD were weak strength for the static balance task, but moderate for the dynamic STS task. Among the evaluation tools used in the present study, f-HHS was most useful for evaluation of dynamic balance ability. CONCLUSION: The results suggest that use of HHS, f-HHS, and BBS as functional evaluation tools does not provide meaningful information regarding balance ability, but that they are useful for evaluating dynamic balance ability of THA patients. The dynamic balance ability at 3 months after THA seems to be under development.

A functional ability and adequate nutritional status are the major determinants of health status, Self-rated health (SRH) is a worldwide method to assess health status and it is recognized as a predictor of morbidity and mortality in the elderly, This study was designed to evaluate the functional ability and nutritional risk according to SRH in the elderly. Four hundred nine free-living elderly people (118 male, 291 female), aged $\geq$ 65 years were interviewed by trained interviewers using structured questionnaires including demographic information, SRH, anthropometric measurements, functional ability, general health status, and nutritional risk. SRH was divided into three status such as “Good”, “Moderate” and “Poor” status. And all the data were analyzed by oneway ANOVA, spearman correlation, and x$^2$ analysis using SPSS 9.0 version at p 〈 0.05. Of all the subjects, 48.9％ perceived their health status as “poor”, and their functional abilities (activities of daily living, instrumental activities of daily living) were more impaired than their counterparts (“good” and “moderate”). Poor self-rated health was also related to: a higher prevalence of illnesses (p 〈 0,001) especially in hypertension, arthritis. Self-rated health was significantly related to food security (p 〈 0.001), food enjoyment (p 〈 0.001) ,and nutritional knowledge (p = 0.0 13). Also NSI checklist total score was the highest in “poor” health status (p 〈 0.001). Better self-rated health was related to better food security, and better food enjoyment. However, smoking, alcoholic intake, exercise, eating behaviors, and demographic characteristics were not significantly different among the three SRH status. SRH was closely related to chronic diseases, functional ability, and nutritional risk in the elderly. Therefore, public health strategies for the elderly should be focused on the elderly who are “poor” in SRH, to improve nutritional status and functional ability, and to reduce risk factors of chronic diseases.
