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.

The structural and energetic preferences of thiacalix[4]biscrown-5 with and without alkali metal ions (Na+, K+, Rb+and Cs+) have been theoretically investigated for the first time using molecular dynamic (MD) simulations and density functional theory (MPWB1K/6-31G(d)//B3LYP/6-31G(d)) methods. The formation of the metal ion complex by the host is mainly driven by the electrostatic attraction between crown-5 oxygens and a cation together with the minor contribution of the cation-π interaction between two facing phenyl rings around the cation. The computed binding energies and the atomic charge distribution analysis for the metal binding complexes indicate the selectivity toward a potassium ion. The theoretical results herein explain the experimentally observed extractability order by this host towards various alkali metal ions. The physical nature and the driving forces for cation recognition by this host are discussed in detail.

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<sub>3,1</sub>) 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<sub>3,1</sub>=0.920-0.983 and r=0.924-0.984). For the test-retest reliability, ICC<sub>3,1</sub>=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.
