Purpose : This study aims to identify changes in the visuomotor coordination and fine motor coordination functions caused by the use of a task-oriented intervention in a child with developmental delay. Methods : The participant, who was a 6-year-old girl, was not diagnosed but showed a developmental delay in overall function. The study period was February 5, 2021, to June 4, 2021, and a single-subject A-B study design was used. The baseline (A) was initially evaluated in the first three sessions to identify the child's functions. In the intervention period, 12 session (B), task-oriented intervention was applied; the child engaged in many of the activities in kindergarten, such as painting, writing, making, and cutting with scissors. Visuomotor coordination and fine motor coordination were equally measured during the baseline and intervention periods. Visuomotor coordination was measured via drawing of an oval according to the Korean Developmental Test of Visual Perception 3 (K-DTVP-3), and fine motor coordination was assessed using the finger-nose touching item of the Clinical Observation of Motor and Postural Skills (COMPS). Results : The mean of the baseline of the K-DTVP-3 oval drawing was 23, and the mean of the intervention period was 39.66. The mean of the baseline of the COMPS finger-nose touching was 0, and the mean of the intervention period was 5.08. Conclusion : Task-oriented intervention seems to have a positive effect on the visuomotor coordination and fine motor coordination abilities of children with developmental delay.

In this paper, we propose the effects of coordinative locomotor training in body alignment of high school baseball players. Coordinative locomotor training was applied to 20 subjects in the experimental group for 30 minutes, 5timess aweek for 4 weeks. Body alignmen was measured using a formertic, and variables representing body alignment included trunk inclination, trunk imbalance, pelvic tilt, pelvic torson, kyphotic angle and lordotic angle. The results of this study were as follows: As for the Body alignment, there were significantly increased in kyphotic angle and lordotic angle in the experimental group. From the above results, it seems that coordinative locomotor training has a positive effects on the body alignment of high school baseball players. The coordinative locomotor training was able to produce confirmation that body alignment change in the case of effective exercise interventions in high school baseball players. Coordinative locomotor training is thought to be effective in preventing physical imbalance in high school baseball.

Objective : The purpose of this study was to identify the effect of crafts and handwriting on bilateral coordination during task performance. Methods : Randomly selected 30 college students without hand disability were invited for the study, and grouped 3(test group 1 for crafts, test group 2 for handwriting, and control group) with 10 students per group respectively. Then Jebsen-taylor hand function test, Purdue pegboard test, and Minnesota manual dexterity test were employed for evaluating changes before and after the intervention. Results : After training intervention of crafts and handwriting for two test groups, test groups showed better bilateral coordination significantly than the control group. Especially test group 1(crafts) showed a bigger difference at Jebsen-taylor hand function test, and likely test group 2(handwriting) did at Purdue pegboard test. Conclusion : It was found that crafts increase bilateral coordination, while handwriting increase hand dexterity during task performance. That is, crafts and handwriting affect tasks differently. Further studies applying various crafts and handwriting for many age groups will be helpful for identifying the better way of occupational intervention for individuals in lack of bilateral coordination.

The purpose of this study was to examine the effects of coordinative locomotor training (CLT) program on the balance for the promotion of life care of elderly obese women. Ten participants of elderly obese women who were able to walk independently without surgery experience of lumbar, hip or knee joint within the past year were recruited and under went the pretest, CLT (20 sessions), followed by the post-test. The test included BMI test using In-body, joint kinematics using myoVIDEO, muscle activation using surface EMG test (erector spinae (ER), external oblique abdominalis (EO), quadriceps femoris (Quad), hamstring muscle (Ham)) and balance tests including dynamic balance test using forced treadmill, Berg balance scale (BBS) and timed up go (TUG). The CLT program was conducted 60 minutes a day, 5 days a week, over 4 weeks period. As a result of this study, The the trunk and hip joints kinematics during the stance and swing phases of gait were a statistical significance levels were set at p <0.05. The ER and EO muscle activation were significantly improved after intervention (p <0.05). The length of gait line and single support line of change of center of pressure (COP) were significantly increased after intervention (p <0.05). The BBS and TUG were also significantly enhanced after intervention (p <0.05). The results of this study showed that CLT program for the improvement of life care had significant effects on improving postural instability, muscle weakness, reduced balance ability and falling risk of obese elderly women. Therefore, it is recommended to apply CLT program to improve life-care through improving balance ability and preventing fall of obese elderly women.

The purpose of the present study was to examine if perception of visual coordination pattern is consistent with the prediction of the HKB model (Haken, Kelso, Bunz, 1985). In addition, this study aimed to see if an additional sensory information using a grid background stabilizes perception of coordination pattern. Participants joined one of two experimental groups, Normal background and Grid background, to participate the pattern recognition training session and the pattern judgment test session. Participants observed $0^{\circ}$, $18^{\circ}$, $36^{\circ}$, $54^{\circ}$, $72^{\circ}$, $90^{\circ}$, $108^{\circ}$, $126^{\circ}$, $144^{\circ}$, $162^{\circ}$, and $180^{\circ}$ coordination patterns characterized by two oscillating dots. The dots oscillated in 0.25 Hz for the pattern recognition training and in 0.5 Hz, 1 Hz, and 2 Hz for the pattern judgment test. Judgment score, absolute judgment error, and judgment stability out of the pattern judgment test were analyzed statistically. The landscape of pattern accuracy and stability data was "inverted-U" shape with slower oscillating frequency conditions. In the faster condition, the accuracy and stability of the judgment decreased with relative phase patterns near $180^{\circ}$. These findings consistent with the prediction of the HKB model. The grid as additional sensory information did not increase accuracy and stability in coordination perception.
