Difference in home participation patterns and environmental factors between Korean children with and without disabilities.

PURPOSE: To identify the participation patterns of Korean children with and without disabilities at home, and the environmental factors affecting their participation. MATERIALS AND METHODS: The Korean Participation and Environment Measure for Children and Youth were applied to 184 caregivers of children aged 5 to 13 years in South Korea. To explore home participation patterns and environmental factors at the item level, analysis of covariance, Pearson's chi-square tests, and radar plots were used. RESULTS: The largest group differences in participation frequency were in "school preparation" and "homework" and those at involvement level were in "indoor play and games," "getting together with other people," "school preparation," and "homework." More caregivers of children with disabilities desired changes in their children's participation in all activities. They also perceived that "physical, cognitive, and social demands of typical home activities," "supplies," and "money" hindered children's home participation. CONCLUSIONS: The findings provide information about how Korean children participated in home-based activities, whether their caregivers desired changes in their participation, and what environmental factors impede their home participation. These can help service providers understand the interaction between participation and environmental factors and offer insight into where their service goals should be focused for the successful participation of children with disabilities at home.Implications for RehabilitationAs children with disabilities spend much time at home, their parents need to consider both how many times their children participate and how much they get involved in home-based activities.Rehabilitation service providers need to focus on whether parents are satisfied with their children's participation in home activities to decide where much effort is needed for meaningfully occupying children's time at home.The goal of rehabilitation services can be to mitigate a poor fit between children's abilities and the demands of activities for successful participation in home activities.Measuring not only the quantity of participation but also the quality of participation is helpful for setting a collaborative goal with parents to improve the participation of children with disabilities at home.

Psychometric properties of the Korean Motor-free Visual Perception Test-4 in healthy people.

OBJECTIVE: This study was conducted to cross-culturally adapt the Motor-free Visual Perception Test 4 (MVPT-4) for use in Korean contexts and examine its psychometric properties. METHODS: The Korean MVPT-4 (K-MVPT-4) was developed via the process of translation, back-translation, and expert committee review. To establish internal consistency, test-retest reliability, concurrent validity and construct validity of the K-MVPT-4, 295 healthy people aged 10 to 79 years participated in this study. Participants completed the measures for the test-retest reliability on two occasions, 2 weeks apart. RESULTS: After three steps of cross-cultural adaptation, the K-MVPT-4 was revised to improve its alignment with Korean cultural norms. Cronbach's α for internal consistency was .857 and intra-class correlation coefficient for test-retest reliability was .949. The K-MVPT-4 scores were significantly correlated with those of three motor-reduced subscales of the Korean Developmental Test of Visual Perception-Adolescent (K-DTVP-A) (r = .44-.46, p < .01). Participants' age significantly influenced the K-MVPT-4 scores (p < .001) while their gender did not affect those scores (p = .409). As the age increased, the K-MVPT-4 scores decreased. CONCLUSIONS: The findings indicated that the K-MVPT-4 is a reliable and valid test that Korean rehabilitation service providers can use with confidence to assess clients' visual perceptual abilities.

Investigation of phase separated polyimide blend films containing boron nitride using FTIR imaging.

Immiscible aromatic polyimide (PI) blend films and a PI blend film incorporated with thermally conductive boron nitride (BN) were prepared, and their phase separation behaviors were examined by optical microscopy and FTIR imaging. The 2,2'-bis(trifluoromethyl)benzidine (TFMB)-containing and 4,4'-thiodianiline (TDA)-containing aromatic PI blend films and a PI blend/BN composite film show two clearly separated regions; one region is the TFMB-rich phase, and the other region is the TDA-rich phase. The introduction of BN induces morphological changes in the immiscible aromatic PI blend film without altering the composition of either domain. In particular, the BN is selectively incorporated into the TDA-rich phase in this study.

A comparison of the swallowing function and quality of life by oral intake level in stroke patients with dysphagia.

[Purpose] This study was conducted to compare the swallowing function and quality of life (QOL) in stroke patients with dysphagia by oral intake level. [Subjects and Methods] Seventy-nine stroke patients with dysphagia were enrolled. All subjects were evaluated by using the Swallowing Function Test (SFT) and the Swallowing Quality of Life (SWAL-QOL) questionnaire. The subjects were divided into two group based on the SFT score: oral intake (OI) and non-oral intake (NOI) groups. The SFT and SWAL-QOL scores were then compared between the groups. [Results] There were significant differences in items in the SFT, except for the respiratory item, between the OI group and the NOI group. There were significant differences in all items on the SWAL-QOL, except for the sleep item, between the OI group and the NOI group. [Conclusion] Oral intake was positively associated the swallowing function and QOL in stroke patients with dysphagia. Safe intervention using oral intake treatments during dysphagia rehabilitation may have a positive effect on the patients' swallowing function and QOL.

Effects of lingual strength training on lingual strength and articulator function in stroke patients with dysarthria.

[Purpose] This study investigated the effects of lingual strength training (LST) on lingual strength and articulator function in stroke patients with dysarthria. [Subjects and Methods] 16 stroke patients with dysarthria were randomly assigned into two groups: the experimental group (n=8) or the control group (n=8). Both groups received the conventional rehabilitation therapy at 30 min/day, 5 times for week, and during 4 weeks, and the experimental group received an additional 30 min of LST using the Iowa Oral Performance Instrument (IOPI). The Maximum Isometric Tongue Pressures (MIPs) was used to assess the lingual strength and the Alternating-Motion Rate (AMR) and Sequential-Motion Rate (SMR) were used to measure the articulator function. [Results] After the intervention, the experimental group showed a significant improvement in MIPs and AMR (/tə/) than the control group. [Conclusion] Findings of this study suggest that LST provides positive effects on lingual strength and articulator function, and thus can be used as an interventional method in stroke patients with dysarthria.

The Standardization of the Clock Drawing Test (CDT) for People with Stroke Using Rasch Analysis.

[Purpose] The aim of this study was to standardize the clock drawing test (CDT) for people with stroke using Rasch analysis. [Subjects and Methods] Seventeen items of the CDT identified through a literature review were performed by 159 stroke patients. The data was analyzed with Winstep version 3.57 using the Rasch model to examine the unidimensionality of the items' fit, the distribution of the items' difficulty, and the reliability and appropriateness of the rating scale. [Result] Ten out of the 159 participations (6.2%) were considered misfit subjects, and one item of the CDT was determined to be a misfit item based on Rasch analysis. The rating scales were judged as suitable because the observed average showed an array of vertical orders and MNSQ values < 2. The separate index and reliability of the subject (1.98, 0.80) and item (6.45, 0.97) showed relatively high values. [Conclusion] This study is the first to examine the CDT scale in stroke patients by Rasch analysis. The CDT is expected to be useful for screening stroke patients with cognitive problems.
