Objective : The aim of this study is to verify the effects of group sensory integrative intervention on praxis and socialization for school-aged children with sensory integration disorder. Method : The subjects are five children aged between 7 and 13 with sensory integration disorder. All children had participated in 26 sessions of group sensory integrative intervention. The Bruininks-Oseretasky Test of Motor Proficiency(BOT-2) and The Scale for Basic Socialized Function were used so as to evaluate the praxis and socialization. One group pretest-posttest design was used to verify the effect of group sensory integration(SI) intervention. The statistical difference between before and after the group SI intervention in the BOT-2, Scale for basic socialized function is tested by the Wilcoxon matched-pairs signed ranks test. Results : There is a significant difference in BOT-2(Z=-2.023, p=.043) and Scale for basic socialized function(Z=-2.023, p=.043) scores comparing pre-intervention with post-intervention. Conclusions : The results of this study showed that the group sensory integration intervention is effective in improving the praxis and socialization for school-aged children. However, it is difficult to generalize the conclusion because the number of subjects was limited and the environmental confounding factors had not been considered. Therefore, in the future research, it should supplement the aspect these limitations before applying the sensory integration intervention in order to suggest standard criteria for norm data.

Objective : This study was designed to determine the effects of sensory integration group therapy with regard to the sensory processing, peer interactions, and task performance, and whether they continue. Methods : Twelve children aged 7 to 13 years enrolled in this study for 60 minutes per session, three times a week for 8 weeks. Sensory integration group therapy consisted of a total of 24 activities that included sensory processing, play skills, and interaction with peers. Short Sensory Profile was used to select subjects. In order to measure the outcome, we used the Short Sensory Profile, Penn Interactive Peer Play Scale and Canadian Occupational Performance Measure at pre, post, and follow-up evaluations. The results were analyzed by means of repeated measures analysis, and the pre-test, post-test, and follow-up tests were compared using the Wilcoxon matched-pair signed rank test. Results : After sensory integration group therapy, sensory processing, peer interaction, and task performance significantly improved(p<.05). In addition, we confirmed that the effects of treatment were maintained in the 4 weeks follow-up test. Conclusion : Sensory integration group therapy is an effective way of mediating effects not only by improving sensory processing skills, but also by providing imitation and training in groups for children in need of peer interaction and linking them to daily life.

This study attempted to contribute to the clinical application of implant operation by making a quantitative nerve examination using a neurometer for the evaluation of sensory disturbances that could be incurred after the implantation in the dental clinics, and it intended to establish an objective guideline in the evaluation of sensory nerve after the operation of implant. An inspection was performed with the frequencies of 2000Hz, 250 Hz and 5 Hz before and after the operations of tooth implant using $Neurometer^{(R)}$ CPT/C (Neurotron, Inc. Baltimore, Maryland, USA) for 44 patients who had performed an implant operation among the patients coming to Daejeon Sun Dental Hospital in 2006 and 30 people for control group. The measuring sites were maxillary nerve ending and mandibular nerve ending of trigeminal nerve according to the implant operating regions. The current perception threshold (CPT) by each nerve fiber was specifically responded under the electric stimulation of 2000 Hz in case of $A{\beta}$ fiber and of 250 Hz in case of $A{\delta}$ fiber and of 5Hz in case of C fiber. The CPT test could be performed to assess the damages of peripheral nerve in the trigeminal nerve area and it stimulated selective nerve fibers by generating the electricity of specific frequency in the peripheral nerve area. The nerve fibers with varied thickness were responsive selectively to the electric stimulation with different frequencies; accordingly, they applied the electric stimulation with different frequencies and the reaction threshold of $A{\beta},\;A{\delta}$ and C fibers selectively responsive to each electric current could be individually evaluated. In the assessment through the CPT, the increase and decrease of the CPT could be measured so that sensory disturbances such as hyperaesthesia or hypoaesthesia could be diagnosed. This study could obtain the following results after the assessment of the CPT before and after the implant operation. 1. In the assessment before and after the implant operation, the CPT in the frequencies of 2000 Hz, 250 Hz, 5 Hz for maxillary branch increased on the whole after the operation and the CPT for mandibular branch in the $A{\beta}$-fiber(2000 Hz) and C-fiber(5 Hz )after the operation increased statistically significantly. 2. For the groups of patients with medically compromised or its subsequent medicinal prescription, there were no significant differences before and after the implant operation and for the control groups, significantly high CPT was shown after the implant operation in the left $A{\beta}$-fiber(2000 Hz) and C-fiber(5 Hz). 3. In the comparison of the measured value of the CPT before the operation between the control group and the implant operation group, the latter group had a significantly high measured value of the CPT in the right $A{\beta}$-fiber(2000 Hz) and C-fiber(5 Hz) and there were significant differences in $A{\beta}$-fiber(2000 Hz) in the CPT assessment after the implant operation for the control group. 4. Male participants had higher CPT than female counterparts; however, there were no statistic significances. In the CPT evaluation before and after implant operation, there were no statistical differences in the male group while the right C-fiber(5 Hz) and left $A{\beta}$-fiber(2000Hz) were significantly high in the female group. 5. In the comparison between the group who complain sensory disturbance and the other group, the CPT increased on the whole in the former group, but there were no statistical significances. In the groups, whom there was an increase in VAS, the CPT after the implant operation in the right C-fiber(5 Hz) increased significantly; meanwhile, in case that the VAS mark was '0' before and after the operation, the CPT after the operation in the left $A{\beta}$-fiber(2000 Hz) increased significantly. This study suggested that the CPT measurements using $Neurometer^{(R)}$ CPT/C, provide useful information of objective and quantitative sensory disturbances for tooth implantation.

The purpose of this study is to examine the correlation between the preferred sensation type and speech sounds, especially on $F_0$ and the speech rates. Data for the sensation types and speech sounds were collected from 36 undergraduate and graduate students (17 male, 19 female). Subjects were asked to read a given text (400 syllables), describe a drawing, and give answers to some questions. We measured speakers' $F_0$ and speech rates. The results show that type V (Visual) has the correlation with the speech rates when type D (Digital) was ruled out, and type A (Auditory) has the correlation with the speech rates when type D was included. Furthermore, the analysis of the mean values of V, A, K (Visual, Auditory, Kinethetic) indicates that type V is characterized with faster speech rates and higher $F_0$ in all parts except for interview and the same is true for that of V, A, K, D (Visual, Auditory, Kinethetic, Digital) in all parts. In conclusion, this study proved that the preferred sensation type has the correlation with $F_0$ and speech rates. Based on the results of this study, $F_0$ and speech rates can be used to analyze the sensation types for individualized education as well as consultation. In addition, this study has great significance in that it lays a foundation for the study on the correlation between a preferred sensation type and speech sounds.

Objective : This study aimed to investigate the importance, performance, and educational needs of sensory integration intervention competency for newly employed therapists who use sensory integration intervention. Methods : The general characteristics, importance, performance, and educational needs of sensory integration intervention competency were investigated for therapists with less than three years of experience in sensory integration intervention. Educational needs and rankings were identified through Borich needs analysis. Results : The competency cluster that newly employed therapists perceived as the most important but with the lowest performance level was "Expertise," and the demand of the "Expertise" competency cluster was also the highest in the analysis of educational needs. The difference in importance and performance in all sub-competencies was statistically significant. In the Borich needs analysis, the rank of educational needs was derived as follows: "Evaluation skill" (5.56), "Analysis skill" (5.50), and "Overall knowledge of occupational therapy" (5.47). Conclusion : It was found that the newly employed therapist using sensory integration intervention recognized professional competency as the most important, while also recognizing that their professional competency was low. Accordingly, education to enhance professional competency was most needed. This study presented basic data for the direction of education to strengthen competency in consideration of the educational needs of newly employed therapists.

Purpose : This study aimed to critically analyze published research papers in Journal of Korean Academy of Sensory Integration and to investigate the research field and trends. Methods : Types of studies, research trends, levels of evidence, participants, funding sources and research areas were analyzed and described by using 97 selected studies published between 2003 and 2014. Results : Every 5 years, the most frequent type of study was experimental research. The numbers of experimental studies and review studies have been increasing. The most frequent level of evidence was one group non-randomized study, followed by case reports. The highest percentage of participants were children with disability and the most common diagnoses were pervasive developmental disorder, developmental delay and intellectual disabilities. Most of the participants was elementary school students and the most frequent sample size was below 10. The percentage of research grant from Korean Academy of Sensory Integration has been over 50% since 2008. The research areas focusing on the standardized assessments were mostly sensory modulation, interaction and development and the non-standardized assessments were behavior observation and clinical observation. Conclusion : Higher level of studies and comprehensive research methods will be needed. The standardized assessment tools with the high sensibility on sensory integration which developed in the domestic need to be developed. Thus, it will be able to contribute to the evidence based practice in occupational therapy.

Objective : This study is to analyze the current trends of research and the subject and method of assessments used in praxis functions through a systematic review. Methods : Through the PubMed, Proquest, and Google database, research articles from January of 1985 through April of 2016 were searched. The keywords used for this search were "praxis AND (validity OR reliability) AND (assessment OR test) AND (preschooler OR child)". Additionally, the name for the assessments from the previous review studies of praxis function assessments was searched. In the end, 14 papers were chosen and 8 assessments that were used in these papers were analyzed. Results : Among the final 14 papers, 10 studies (71.4%) were level III (non-randomized one group) which was the largest number in this review, followed by 4 studies (28.6%) with level II (non-randomized two groups). There was no RCT study which is the level of evidence of the level I research. The results for the analysis of the subjects' age of the final 8 assessments that were chosen showed that most of the praxis function assessments were developed for children. There were 6 assessments of which their reliability and validity were verified and other 2 assessments of which their reliability and validity were not both verified. Conclusion : This study proposes the current trends of research of praxis function assessments. The study's significance is that it provides a research evidence when choosing and utilizing assessments for the children.

Background : Theory of Sensory Integration (SI) was initially developed with an effort to understand children's behavior by Jean Ayres and has been evolved with extensive research by occupational therapist practitioners and researchers since in the latter of the 20 century. With extension of recognition to SI, various professions begin to refer their clients who are children with sensory integration dysfunction. Upon those referrals, occupational therapists normally use Short Sensory Profile (SSP) to screen and decide whether SI therapeutic intervention is needed or not. Objective : Purpose of this study is (1) to examine any difference between different age groups and genders for children who are seven to nine years old; (2) to compare the score results of those Korean children with the original Standard which is established for American children: and (3) to compare tendency of response for each item between children with- and without SI dysfunction. This study was intended to validate test items of the SSP and determine whether the original standard of SSP is applicable for Korean children. Method : 155 students (81 for male, 74 for female) underwent SI evaluation using the Korean-translated SSP. 52 student (22 for male, 30 for female) were 7 years old, 54 students (32 for male, 22 for female) were 8 years old, 49 students (27for male, 22 for female) were 9 years old. Results : There is no significant difference of SSP score by neither age nor gender. In comparison the average score and sensory integrative disorder with the American Standard, there is significant difference on score of sub-item and total score. For six items, there is no significant difference on the tendency of response between children with- and without SI dysfunction. Conclusions : It is concluded that the original standard is suitable for Korean children aged seven to nine. The six test items that children without SI dysfunction shown similar tendency to respond are questionable to be appropriate as screening test item. It is suggested to proceed to do further item analysis study and extend the study to broad age groups, so develop the most appropriate Standard of SSP for Korean children.
