The purpose of this study is to provide basic information for the development of pants patterns with a high level of fit and comfort through calculating surface variations of lower body parts by movement, grouping them into factors, and analyzing how their surface variations link to one another. The achieved results will help determine essential elements for constructing pants patterns, such as key measurements of lower body parts, the amount of ease values and selection of fabrics, which should be taken into consideration for allowing better movement in clothing. The study required lower body 3D scanning of women for analysis, and 13 women between the ages of 20-24 participated in the scanning, which was done by using Artec Eva 3D scanner. Their scanned data were digitalized and converted to measure the values of their lower body surface length and girth in pre-determined positions such as walking, stair climbing and sitting on a chair. These measurements have been statistically analyzed through SPSS 21.0 to obtain the average amounts and rates of extension for each of the measurement item. Some of the highlighted study results are as follows: The surface length and girth measurements were grouped into 4 factors based on their average extension rates. The results from correlation analysis between measurement items within each factor demonstrated that common items linked to all the changes in the values of other items in the three movements. But in most cases, items were not always correlated with each other for different movements. The results also showed that there were correlations between girth measurements, length measurements, and girth and length measurements. Therefore, key measurements for daily pants should be determined within reasonable estimations between relevant measurement items, while the measurements for work pants, which often withstand certain postures or repetitive movements, may require measurement items that are appro priate for, and closely related to, certain movements or tasks.

The purpose of this study was to determine the effect of the foot rotation on the lower limb muscles. Fourteen subjects performed step-up/step-down at a cadence of 80 beats/min, exercises with the foot neutral, $35^{\circ}$ internally rotated, and $35^{\circ}$ externally rotated, respectively. For each variable, a one-way analysis of variance (ANOVA) was used to determine whether there were significant differences between genders and among the eight types of jump. When a significant difference was found in jump type, post hoc analyses were performed using the Tukey procedure. A confidence level of p < .05 was used to determine statistical significance. The results showed that significant changes in averaged IEMG values occurred with the internal rotation of the foot in the lateral gastrocnemius during the knee extension, and in the semitendinosus during the knee flexion. During the knee extension, however, the internal rotation of the foot produced a significantly lower Averaged IEMG values than the neutral foot position in the medial gastrocnemius. The results also found that the peak IEMG activity of the rectus femoris during the knee extension for the external rotation of the foot was Significantly higher than the corresponding values in the neutral position of the foot, while the intenal rotaion of the foot exhibited a significant difference with the neutral position of the foot in the semitendinosus during the knee flexion. In general, the foot rotation position did not influence the average IEMG and Peak IEMG values of most muscles. The practice of adopting foot rotation to selectively strengthen individual muscles of the lower limb was not supported by this study. The external rotation of the foot produced high muscle activities in the quadriceps during the knee extension. For the knee extension, therefore, maintaining a laterally rotated position should be need for stable and comfortable position.

The WeeFIM is an outcome measure used worldwide to evaluate the functional abilities of children. The aim of this study was to evaluate the psychometric properties of WeeFIM in Korean children with cerebral palsy (CP) using the Rasch model. The mean age of the participants (92 boys and 53 girls) was 10.6 years (SD=2.3, range 5~15 years). The Winsteps software was used for analyzing the internal construct validity and reliability of WeeFIM. For analyzing the internal validity the motor and cognitive area items of the WeeFIM were analyzed both together and separately. When all 18 items were analyzed 4 were considered to be misfits; upper extremity dressing, lower extremity dressing, toileting, and comprehension. When only the 13 motor items were analyzed, toileting, bladder management, and bowel management were considered misfits. In addition, only comprehension was considered as a misfit among the 5 cognitive items. The most difficult motor items were stair climbing, and bathing. The simple ones were eating, bowel management, and bladder management. The most difficult cognitive item was problem solving, and the simplest one was comprehension. The person separation indexes and reliability for combined and divided instruments were reported as excellent. These results demonstrated the applicability of WeeFIM to Korean CP children with satisfactory reliability and validity. Further studies should include young children with CP and compare item difficulty among the different types of CP. In addition, the Korean normative data of nondisabled children should be used to compare the cultural differences between Korea and other countries.

The functional disabilities post arthrodesis of the ankle include difficulty in climbing inclined surface, such as hill, ramps, or stair even through without pain. There will be periankle joints arthrosis as time passes. Total ankle replacement permits remobilization, no need for prolonged immobilization. There will be no increas in the mechanical stress of the neiboring joint. Total ankle replacement has been proposed as an alternative to arthrodesis in the management of painful arthrosis of the tibiotalar joint recently. We performed 7 cases of replacement from 1990. 4. 1 to 1996. 7. 1 with 2-3 years follow up. A retrospective review was undertaken for 7 patients with the arthrosis of tibiotatar joint. The results were as following. 1. The clinical results according to the point system for ankle study evaluation were excellent in 2 cases, good in 4 cases, and fair 1 case. 2. The improvement was especially obvious in terms of pain and functional recovery. 3. Total ankle replacement especially unconstrained type seems quite good alternative to arthrodesis.

Objective: Patellofemoral pain syndrome (PFPS) is a condition that is characterized by patellar discomfort or pain that is aggravated during certain activities such as ascending/descending stairs. The Patellofemoral Disability Index (PDI) was developed to assess the effect of pain on functional activities in individuals with PFPS. The objectives of the current study were to determine the internal consistency, test-retest reliability, and validity of this index. Design: Cross-sectional study. Methods: Forty-one subjects who had PFPS with a mean age of $28.8{\pm}5.0years$ and a mean body mass index of $25.6{\pm}4.7kg/m^2$ participated in the study. All subjects were concurrently enrolled in a clinical trial for which they were instructed to complete hamstring-resistance exercises for 4 weeks. Over the course of the intervention, they completed both the PDI and the Oswestry Disability Index (ODI) at baseline after two weeks, and after four weeks. Pearson correlation coefficient was used to assess the criterion validity. Cronbach's ${\alpha}$ was used to examine the internal consistency. Intraclass correlation coefficients with 95% confidence interval were computed to examine test-retest reliability. Results: Subjects' responses within both the PDI and the ODI yielded Pearson correlation coefficient values that were positive and highly significant (range, 0.73-0.97; p<0.001). There was a high level of internal consistency (Cronbach's ${\alpha}{\geq}0.8$), with the exception of stair climbing (Cronbach's ${\alpha}=0.65$). Intraclass correlation ranged from 0.87 to 0.92, indicating high levels of test-retest reliability. Conclusions: The PDI is a valid, reliable, and feasible method of assessing pain and functional ability in patients with PFPS.

Purpose: The purpose of this study was to examine the influence of foot angles on plantar pressure and the center of pressure (COP) trajectory length during level walking. Methods: The study subjects were 30 female university students without orthopedic diseases in the foot. The foot angle was divided into three forms (out-toeing, normal, in-toeing). The subjects practiced each type of gait, and then performed each of level walking, three times, and their averages were calculated. A plantar pressure measurement instrument was used, and the maximum force was obtained by dividing the foot into nine regions covering the anterior medial-lateral, middle medial-lateral, and posterior medial-lateral. The COP trajectory length was statistically processed by obtaining medial-lateral, anterior-posterior, and entire travel distance. Results: During normal walking, the maximum force was significantly higher in the anterior lateral than in the other areas, and the COP trajectory length was significantly shorter in the front-back and entire travel distances (p<0.05). During stair climbing. Conclusion: Walking at abnormal foot angles does not cause appreciable problems in the short term as pressure is concentrated on a specific plantar part. However, it becomes the cause of deformed foot structures and can result in musculoskeletal disabilities in the long term. Therefore, a kinesiatrics-based intervention is required to maintain normal foot angles.

Objective : This study is conducted to find the influence on upper extremity function, cognitive function and activities of daily living when stroke patients receive task-oriented training in group or individually. Methods : Twenty-six inpatients are assigned to two groups(task training group and individual training group) randomly, who receive rehabilitation therapy after stroke diagnosis for 5 months(june to november, 2012) in a hospital. Both groups receive a task-oriented training for 30 minutes a day for 3 weeks. FMA were used to measure upper extremity function, K-MMSE were used to measure cognition, and MBI for ADL. Results : Before training. two groups were not different significantly in upper extremity function and cognitive function. But in activities of daily living, bathing self(p<.001), feeding, personal hygiene and total score(p<.05) are higher in group training group. After training, upper extremity function is higher in individual training group(p<.001). In both training group, upper extremity function, feeding, personal hygiene, bathing self, dressing, toilet, chair/bed transfers, ambulation and stair climbing, total score are improved significantly(p<.05). In comparing of variation before and after training, upper extremity function(p<.001), feeding and total score of activities of daily living are more improved significantly in individual training group(p<.05). Conclusion : The outcome shows that task-oriented training can improve upper extremity function and activities of daily living in both training group. Especially, the more upper extremity function is improved, the more activities of daily living is improved. In the future, it will be necessary longitudinal study for a long time for more patients.

This study was carried out to idenify the health problems and needs of crippled persons in order to develop a community based rehabilitation service program through public health center. Information on health problems and needs were obtained from 120 crippled persons staying at home by questionaire and a measuring ADL. The results were summarized as follows 1. Among 120 subjects, male crippled (70.3%) outnumbered female crippled (29.7%). Many crippled persons belonged to the 40-49 age group (33.6%) while others were over 60 years (17.4%). There were 36.8% crippled persons with an elementary education, 26.5% had completed high school, 14.5% had completed middle school. 31% of the crippled persons were employed but most of them had unskilled jobs. 80% of the respondents replied that their monthly income was under 800,000 won. 2. The major causes of their handicap were due to acquired factors(92%) such as accidents, in fectious & communicable diseases and chronic diseases rather than congenital factors(8%). Crippled persons who belong to the first grade of disabilities were 14.8%, the second grade 35.7%, the third grade 21.7%, the forth grade 12.2%, the fifth grade 12.2% and the sixth grade 3.5%. 3. This study measured the degree of the ADL of crippled persons by a modified Barthel Index including 11 items. 73.5% of them were fully independent, 8.5% required minimal help, 2.7% required moderate help, 6.0% required substantial help and 9.4% were unable to perform task. In response to the 11 items of ADL, crippled persons required more help in stair climbing, ambulation and bathing than in other items. 4. In responding to concerning health problems, 10.3% of the subjects replied with incontinence, 8.5% malnutrition, 7.6% fecal incontinence and bedsores 2.6%. Chronic diseases which needs treatment were chronic pain(61.0 %), hypertension(16.5%) and diabetes(16.5%) 5. To the question of what type of rehabilitation services subjects required, chronic diseases management(52.1%) and physical therapy (41.2%) were the highest. The most important social welfare services subjects required were economics support (51.3%) and introductions to job opportunities(42%).

The purpose of this study was to identify the validity, reliability, and discriminative index of the Korean version of Modified Barthel Index (K-MBI). For this, two hundreds twenty-thee stroke patients participated. Activities of daily living were measured through using K-MBI. Factor analysis was performed for identifying the construct validity and internal consistent and discriminative index were calculated. The result of factor analysis was that the 10 items of K-MBI have communality above .50, and was constructed one factor. Explained variance was 72.184%. The order of factor loading value was toileting, personal hygiene, transfer from bed to chair and back, ambulation/wheelchair, dressing, feeding, bowel control, bathing, bladder control, and stair climbing. Cronbach ${\alpha}$ of K-MBI was .994. The range of discriminative index was .783~.909, and was acceptable. One factor of K-MBI was identified through factor analysis, and reliability and discriminative index was also identified. Various psychometric properties of K-MBI should be investigated in further studies for valid assessment of activities of daily living in stroke patients.
