( Jooyeon Ko ),( Youngyoul You ) 대한물리치료학회 2015 대한물리치료학회지 Vol.27 No.4

Purpose: The purposes of this study were to develop the Korean version of the trunk impairment scale (K-TIS) and to examine reliability and responsiveness of the K-TIS in patients with stroke. Methods Subjects of the study were 51 stroke patients (mean age: 57.78 years) recruited from two stroke clinics. For the interrater and test-retest reliability, two raters measured the K-TIS two times using video clips with an interval of 2 weeks. For the responsiveness, intensive physical therapy training was provided to all participants 2 times a day for one month or three months depending on the onset of the stroke and the admission rules of the two clinics. Inter-rater reliability and test-retest reliability of the K-TIS three subscales (static sitting balance, dynamic sitting balance, and coordination) scores and total scores were examined using intra-correlation coefficient (ICC_3,1) and Pearson`s correlation coefficient (r). To examine responsiveness, the minimally important difference (MID) was calculated with effect size. Results: Inter-rater reliability of the K-TIS subscales and total scores were all high (ICC_3,1=0.920-0.983 and r=0.924-0.984). For the test-retest reliability, ICC_3,1=0.805-0.901 and r=0.806-0.903, and the MID for acute and post-acute as well as chronic stroke patients remained in the mean change range. Conclusion: It is suggested that the K-TIS might be used for clinical and research purposes as a standardized tool for stroke patients. In addition, it can also be useful in establishment of treatment goal(s) and planning treatment program(s) for patients with stroke.

Results: Inter-rater reliability of the K-TIS subscales and total scores were all high (ICC3,1=0.920-0.983 and r=0.924-0.984). For the test-retest reliability, $ICC_{3,1}$=0.805-0.901 and r=0.806-0.903, and the MID for acute and post-acute as well as chronic stroke patients remained in the mean change range.

Reliability and Concurrent Validity of Korean Version of the Trunk Control Measurement Scale (K-TCMS) for Children with Cerebral Palsy

Ko, Jooyeon,Jung, Jeewoon 대한물리치료학회 2017 대한물리치료학회지 Vol.29 No.1

Purpose: This study was conducted to develop a Korean version of the trunk control measurement scale (TCMS) and examine the reliability and concurrent validity of the K-TCMS in children with cerebral palsy. Methods: Subjects for the study were 23 children with cerebral palsy (CP)(mean age: 84.70 months) recruited from one CP clinic. For the interrater and test-retest reliabilities, four raters (A, B, C, D) measured the K-TCMS two times using video clips with an interval of two weeks. For the concurrent validity, the Korean version of the gross motor function measure (K-GMFM) was chosen. Inter-rater reliability and test-retest reliability of the three K-TCMS subscale (static sitting balance, dynamic sitting balance and dynamic reaching) scores and the total scores were investigated using the intra-correlation coefficient ($ICC_{3,1}$). Spearman's correlation coefficient (r) was calculated to investigate the concurrent validity. Results: The inter-rater reliability of the K-TCMS subscales and total scores were all high ($ICC_{3,1}=0.968-0.992$). For the test-retest reliability, $ICC_{3,1}=0.827-0.962$. The concurrent validity between the K-TCMS's total and three subscale scores and K-GMFM's total score were r=0.600-0.667. Conclusion: The results suggest that the K-TCMS can be used in clinical and research settings as a standardized tool for CP children. The K-TCMS might be also useful for selecting treatment goals and planning interventions for children with cerebral palsy.

Functional Improvement after the Gross Motor Function Measure-88 (GMFM-88) Item-Based Training in Children with Cerebral Palsy

( Jooyeon Ko ) 대한물리치료학회 2017 대한물리치료학회지 Vol.29 No.3

Purpose: The aim of this study was to investigate applicability of the GMFM-88 in planning intervention for CP children. Specifically, this study assessed functional improvement after a four-week GMFM-88 item-based training in CP children divided into three age groups (≤24 months, 25-48 months, and >48 months) and five levels of the gross motor function classification system (GMFCS). Methods: Subjects were 264 children with CP (mean age 32.90 months) recruited from one CP clinic. The GMFM-88 item-based training was planned for each child, after an interview with its caregiver. To investigate functional improvement after the intervention, minimum important difference (MID) and MID proportion for the change in scores of GMFM-88 were calculated. Results: The GMFM-88 scores increased after the interventions in all three age groups (p<0.05). In particular, children with CP aged ≤24 months and at the GMFCS level II showed greater functional improvement after training. Conclusion: This study found that the GMFM-88 item-based training would be used to plan activity-oriented intervention both in clinic and home in each CP child.

Development of Korean the Version of the Developmental Coordination Disorder Questionnaire (DCDQ-K)

Ko, JooYeon,Lee, WanHee,Woon, JungJee,Kim, YoungA 대한물리치료학회 2020 대한물리치료학회지 Vol.32 No.1

Purpose: This study translated the developmental coordination disorder questionnaire'07 (DCDQ'07) into Korean and investigated the psychometric properties of the Korean DCDQ (DCDQ-K) using validation processes. Methods: The subjects were 300 parents with typically developing children aged 5-15 years (162 girls and 138 boys, mean age 9.24 years, SD 2.59) across the country. To develop the Korean DCDQ, a forward-backward-original author feedback-panel meeting-pilot study with parents was done. The internal consistency, test-retest reliability performed two weeks apart, content validity, discriminative validity, convergent validity, and constructive validity were examined with the pre-version of the DCDQ-K. Results: Approximately 15.33% of the subjects were probably shown DCD using DCDQ-K. Significant differences in age and province were observed in the DCDQ-K total score. The reliabilities and validities were good in the DCDQ-K. Conclusion: The DCDQ-K is a reasonable screening tool for DCD children.

Epidermolysis bullosa simplex (EBS) is a rare genodermatosis characterized by mechanical stress-induced blistering of the skin. Its pathogenesis is mainly associated with defects of attachment of basal keratinocytes to the underlying dermis, resulted from keratin (KRT) 5 and KRT 14 mutation. We experienced a sporadic case of EBS with a novel KRT 14 mutation. A 1-day-old female full-term newborn presented with multiple bullae and erosions mainly on hands and feet. She did not show signs of other systemic diseases. Familial history of dermatologic diseases was absent. The histopathologic examination showed intraepidermal cleft. Direct immunofluorescence finding was negative. Electromicroscopy showed that the level of cleavage was low within the basal keratinocytes, just above the level of the hemidesmosomes and keratin clumps were not observed. Additional genetic analysis by exon sequencing revealed a novel de novo heterozygous missense mutation c.369T>G (p.Asn123Lys) in KRT14 gene. On the other hand, other family members including parents and her brother did not show any abnormalities in KRT14 gene. From these findings, she was diagnosed with EBS. She is receiving conservative treatment and is being followed-up for 6 months without serious complications. Herein, we report a rare case of neonatal EBS with de novo KRT14 gene mutation, which has been only once reported in the literatures to our knowledge.
