Background: Research efforts to improve the pulmonary function of children with cerebral palsy (CP) need to focus on their decreased diaphragmatic ability compared to normal children. Real-time ultrasonography is appropriate for demonstrating diaphragmatic mechanisms. Objects: This study aimed to compare diaphragm movement, pulmonary function, and pulmonary strength between normal children and children with CP by using ultrasonography M-mode. The correlation between general characteristics, diaphragm movement, pulmonary function, and pulmonary strength was also studied. Methods: The subjects of this study were 25 normal and 25 CP children between five and 14 years of age. Diaphragm movement was measured using real-time ultrasonography during quiet and deep breathing. Pulmonary function (such as forced expiratory volume in one second; FEV1 and peak expiratory flow; PEF) and pulmonary strength (such as maximum inspiratory pressure; MIP and maximum expiratory pressure; MEP) were measured. A paired t-test and Spearman’s Rho test, with a significance level of .05, were used for statistical analysis. Results: The between-group comparison revealed that normal children had significantly greater diaphragm movement, FEV1, PEF, MIP, and MEP (p<.05) than CP children. The results showed that general characteristics were significantly related to FEV1, PEF, MIP, and MEP (p<.05). Conclusion: In clinical settings, clinicians need to concern decreased diaphragm movement, pulmonary function, and pulmonary strength in CP group compared to normal children.

Multi-sensory systems, including the visual, somatosensory, and vestibular ones, are involved in maintaining standing balance. The organization of these sensory systems is as important as the efficiency of each individual system in maintaining optimal balance. The purpose of the present experiment was to investigate the developmental changes in static standing balance and sensory organization under altered sensory conditions. This study involved 64 children (from 4 to 15 years of age) and 17 young adults. The children were divided into four age groups: 4~6, 7~9, 10~12, and 13~15 years. Static standing balance was assessed with the one-leg standing test under four different sensory conditions: the children stood on a firm surface with (1) eyes open or (2) closed, and they stood on a foam surface with eyes (3) open or (4) closed. In balancing ability, the age groups exhibited significant differences. The function of sensory organization for balance control was poorer for the children than for the young adults. The functional efficiency of the somatosensory system of the children aged 7~9 years was at the young adults' level, and the visual function of the children aged 10~12 years had also reached the young adults' level. However, the functional efficiency of the vestibular system of children was significantly lower than that of the young adults, even at the age of 15 years. This may indicate that sensory organization and standing balance are still developing after the age of 15 years.

Although many children with cerebral palsy have problems with their eye movements available data on its intervention is minimal. The purpose of the study was to determine the effectiveness of the postural movement normalization and eye movement program on the oculomotor ability of children with cerebral palsy. Twenty-four children with cerebral palsy (12 male and 12 female), aged between 10 and 12, were invited to partake in this study. The subjects were randomly allocated to two groups: an experimental group received the postural movement normalization and eye movement program and a control group which received conventional therapy without the eye movement program. Each subject received intervention three times a week for twelve weeks. The final measurement was the ocular motor computerized test before and after treatment sessions through an independent assessor. Differences between the experimental group and control group were determined by assessing changes in oculomotor ability using analysis of covariance (ANCOVA). The changes of visual fixation (p<.01), saccadic eye movement (p<.01) and pursuit eye movement (p<.01) were significantly higher in the experimental group than in the control group. These results show that the postural movement normalization and eye movement program may be helpful to treat children with cerebral palsy who lose normal physical and eye movement.

Objectives : This study evaluated norms for fine motor dexterity skills on kindergarten and elementary school children. Method : Participants were recruited from five kindergartens and two elementary schools in Seosan area. The sample consisted of 160 healthy students ranging in age from five to eight years. The Grooved Pegboard Test (GPT) was utilized to investigate fine motor dexterity. Results : The GPT showed statistically significant differences in hand dominance based on the findings that the scores of nondominant hands were substantially lower than those of dominant hands (p<0.05). The GPT showed significant age group differences in which 8 year old group demonstrated substantially higher scores than those of all other younger age groups (p<0.05). The results indicated a positive relationship between age and GPT scores. Conclusion : The results of this study support the results of previous studies that compared hand function between healthy children and abnormal children. These data will provide standard value of GPT for occupational therapists.

The purpose of this study is to find the standard value of hand width, of grip strength and of pinch strength by age, sex, and by left hand and right hand and also to find how the general characteristics influences grip strength and pinch strength. Martin Vigorimeter (List No. 17-27-01) was used for measuring grip strength, and the pinch gauge (0∼30 lbs) of B&L engineering for measuring pinch strength. The subjects of this study are the children at the age of three to seven years, who attending the babies' play room, kindergarten and the primary school in Seoul and the Kyungki province area. They all were normally developed without any significant neurology problem. wo hundred girls and two hundred boys were partifipated in this study. They were divided into ten subgroups according to the age of six month interval. Each group consisted of forty children of twenty boys and twenty girls. Analysis of data presents the technical statistics upon the hand width of right and left hand and the grip strength and pinch strength according to the age and sex. Multiple regression analysis using mixed liner model was operated in order to find how the general characteristics (of the age, sex, and side of hand) influence hand width, grip strength, and pinch strength individually. Also, we calculated the correlation among hand width, grip strength and pinch strength under the condition of controlling general characteristics; and to find correlation between the right hand and the left hand of the age and sex, we carried out paired t-test and came to the conclusion as follows: 1.　Hand width is significantly increased with the increase of age (p<0.01). The increase of hand width according to age, boy is wider than that of girl significantly (p<0.01), and the right hand is wider than that of the left hand significantly (p<0.01). 2.　Grip strength is significantly increased as the age and hand width increased (p<0.01). The increase of grip strength according to the age, boy is stronger than that of girl significantly (p<0.01), and grip strength of the right hand is stronger than that of the left hand(p<0.01). 3.　Three-jaw pinch strength is increased as the age, hand width and grip strength are increased(p<0.01). But there is no significant difference of three-jaw pinch strength according to sex and the side of hand(p>0.05). 4.　Tip pinch strength is significantly increased as the age and grip strength are increased(p<0.05). The increase of tip pinch strength according to the age, boy is stronger than that of girl significantly (p<0.05), but there is no significant difference between the right hand and the left hand(p>0.05). 5.　Lateral pinch strength is significantly increased as the age and grip strength are increased(p<0.01). But the increase of lateral pinch strength, there is no significant difference according to the hand width, sex and the side of hand(p>0.05). 6.　The test of correlation among hand width, grip strength and pinch strength showed the correlation between grip strength and pinch strength was stronger than the correlation between hand width and pinch strength(0.3<r<0.7). There was strong correlation between each pinch strength(0.3<r<0.7). Above all, the correlation of three-jaw pinch strength and tip pinch strength was strongest(0.7<r<1.0). 7.　The test of hand width according to the age and sex, and the difference between the right hand and the left hand in grip strength and pinch strength showed that there was significant difference against all the test of hand width, of grip strength, and of pinch strength in the age group from seven years and six months to seven years and eleven months than the age group under six years, specially in girls group(p<0.05).

Physiological Cost Index (PCI) of walking has been widely used to predict oxygen consumption in healthy subjects or patients. The purposes of this study were to evaluate the predictability of physiological cost index of upper extremity exercise with a sander for the amount of exercise and cardiac function and to find out most efficient speed of exercise. Upper extremity exercise was conducted in 67 healthy children (age 4 -12) for 2 minutes with a sander in two different speeds, such as self selected comfortable and self selected fast speeds. Speed of sander was calculated, and heart rate were measured before and immediately after the exercise. Physiological Cost Index (PCI) of upper extremity exercise was calculated for statistical analysis. The result were as follows; 1.　Comfortable and fast speeds of the sander went up according to the increase of age, sander PCI during exercise by it, decreased as the age increased with significant difference in each group (p=0.00). The heart rate change during exercising by it, there was no significant difference. 2.　The heart rate change during the exercise by sander increased as the speed of sander increased. Linear regression equation between the heart rate change during the exercise by sander and the speed of sander were 'Y (the heart rate change by sander) = 0.332X (the speed of sander) + 12.731' (R²= 0.154). Stepwise regression showed the speed of sander affected the change of heart rate positively, and the age affected negatively (R²= 0.242, p = 0.00). 3.　The PCI during the exercise by sander decreased as the speed of sander increased. Linear regression equation between the PCI during the exercise by the sander and the speed of sander were 'Y (the PCI by sander) = -0.00495X (the speed of sander) + 2.091'(R²= 0.267), and statistic significant was recognized (p = 0.00). 4.　The speed of exercise by sander it increased as the age increased. Linear regression equation between the speed of the sander and the age were 'Y (the speed of sander) = 2.481X (the age) -0.893(R²= 0.452), and statistic significant was recognized(p = 0.00). 5.　The reliability analysis for the method of examining each PCI, showed high reliability coefficients and the value of alpha was 0.9337. In conclusion, PCI of the upper extremity exercise with a sander could be thought to predict the energy consumption from the speed of sander as there was a linear relationship between the speed of sander exercise and heart rate change with exercise. PCI of the upper extremity exercise with the self selected fast speed was most efficient. Further study with oxygen consumption analysis is recommended to apply PCI in upper extremities in patients with different pathologies in motion.

Recently the researches to enhance the hand function of brain injured clients are increased. One of those aspects is related to in-hand manipluation. In-hand manipulation is divided to four types: that is finger-to-palm translation. palm-to-finger translation, shift, and rotation. The purpose of this study was to find type of in-hand manipulation in normal adults in six activities and to differentiate the pattern of in-hand manipulation between normal adults and children with cerebral palsy. The participants were consist of twenty normal adults and twenty cerebral palsy. children. As a results, cerebral palsy children significantly used at lower frequence than normal adults in 3 activities. Also, in the other items, there are some pattern to differenciate between normal adults and cerebral palsy children but that was not significant statistically. The development of in-hand manipulation skills involves improvement in the dimension of activities of daily living skills training and more detailed evaluation method will be needed.

Manual dextrity is frequently evaluated in rehabilitation to estimate hand function. The Box and Block Test(BBT) mearsures gross manual dextrity. The first goal of this study was to verify the test-retest reliability of the BBT for 4, 5 years old children. The second goal of this reserch was to develop normative data from 35 convenient sample of normal children. The results showed the test-retest reliability was high (Pearson product moment correlation coefficients of 0.71 to 0.82).

The purpose of this study was to investigate whether the function of the non-affected hand of hemiplegic children is comparable to the hand function with both normal hands. The subjects of the study were 19 hemiplegic children and 20 normal children, all six years of age. The hemiplegic children were treated at one of three facili- ties: Yonsei University Rehabilitation Hospital, Seoul Community Rehabilitation Center and Inchon Severance Hospital during in period March to April, 1996. The normal children were randomly selected from a kindergarten in Inchon City. All hand function was measured by Jebsen Hand Function Test. Subtest was analysed statistically using the basic statistic analysis, Mam-Whitney test and Pearson correlation test . The results were as follows: The normal children had faster right hand function than herniplegic children whose nonaffected hand was their right hand, for the small objects, simulated feeding, checkers subtests. Normal children had faster left hand function than hemiplegic children whose nonaffected hand was their left hand, for the small objects, checkers, large light objects and large heavy objects. The unaffected hand function of the hemiplegic children had a negative correlation with time of diagnosis, and treatment durat ion. These results showed that the nonaffected hand function of hemiplegic children dif- fered from the respective hand of normal children. Therefore, when hemiplegic children are treated, both the affected and unaffected hand must be treated as this will affect the treatment result.

The purposes of this study were 1) to determine the relationship between antigravity control(supine flexion and prone extension) and postural control(static and dynamic balance) by age, 2) to determine the quality of antigravity and postural control, and 3) to determine whether sex difference correlates with differences in antigravity and postural control in young normal children. We tested 120 children aged 4 to 7 years. The study results showed a significant relationship between antigravity and postural control by age. Quality scale measurements(r=0.90) indicated that the children in this study had not yet developed full antigravity or postural control. The study results revealed differences between sexes(f>m in 5 of 7 tests) and a significant relationship by age in antigravity and postural control.
