OBJECTIVES: This study was performed to find out static two-point discrimination (TPD) in fingertips. METHODS: This was a cross-section, measure study of static two-point discrimination involving healthy young adults. Measure was completed by 48 college students in Andong Science College from June 1 to 12, 2004. The minimal distance at which two-points could be discriminated was measured from thumb to little finger. RESULTS: For dermatomal regions of the fingertip, mean values ranged from 3.3mm to 4.9mm (thumb 3.6mm, index finger 3.3mm, middle finger 3.8mm, ring finger 4.2mm, and little finger 4.7mm in the left hand; thumb 3.7mm, index 3.5mm, middle 4.0mm, ring 4.3mm, and little 4.9mm in the right hand). A significant difference in discrimination ability was found between men and women, 3.5mm for women showed a greater sensitivity than 4.1mm for men in the left middle fingertip(p=0.0109), also 3.9mm for women showed a greater accuracy than 4.5mm for men in the left ring fingertip(p=0.0388). In the right index fingertip, women (3.1mm) have a narrow distance than men (3.6mm)(p=0.0329). The minimal distance of TPD was found a significant difference between 20 and 30 years in age. 4mm for 30 years showed a greater distance than 3.5mm for 20 years in the left thumb fingertip(p=0.0354), also, 3.8mm for 30 years showed a greater distance than 3.2mm for 20 years in the left index fingertip(p=0.0174), and 4.3mm for 30 years showed a greater distance than 3.7mm for 20 years in the left middle fingertip(p=0.0444). In the right index fingertip, 20 years (3.2mm) had also a narrow distance than 30 years (4.1mm)(p=0.0020), 20 years (3.9mm) showed a narrow distance than 30 years (4.6mm) in the right middle fingertip(p=0.0124), and 20 years (4.1mm) showed a greater sensitivity than 30 years (5.0mm) in the right ring fingertip(p=0.0070). CONCLUSIONS: Our results suggest that distance of TPD in the both index fingertips for 20 years women was significantly narrowed.

This study was conducted to investigate the evaluation of nutrition and exercise education program on weight control for obese children. The subjects of this study were 28 obese children and their parents living in Geyongnam area. The weight control program consisted of exercises for children and nutrition education for both children and their parents. The BMI values of the children were significantly reduced from $27.96\;kg/m^2$ to $27.22\;kg/m^2$ after 11 weeks (p < 0.001) and to $27.65\;kg/m^2$ after one year. Dietary habits and exercise patterns were also changed positively. For the children, while the frequency of eating breakfast and appropriate chewing habits were increased, the percentages of eating in inappropriate position and the frequency of buying snacks were decreased (p < 0.001). In terms of exercise, the proportion of doing exercise more than 30 minutes, participating in physical activity classes actively, and walking rather than taking a car were significantly increased. Nutrition knowledge of both the student and parent respondents were significantly increased when measured immediately after the education and even a year after compared to their knowledge status measured before the program (p < 0.001). Both the students (82.1%) and parents (96.4%) were satisfied with the overall weight control program. Exercise therapy was chosen as the most beneficial content. Reparticipation intention was comparable between the students (28.6%) and their parents (67.9%). A year after survey results revealed that 71.4% of students controlled their weight by doing regular exercises (55.0%) and controlling overeating (45%). Parents often applied healthy cooking methods (89.3%) and low calorie menus (64.3%), which they learned from nutrition education. Most parents perceived that the weight control program was helpful for their children (89.3%) and themselves (92.9%) as well.

Objective: The purpose of this study was to perform a muscle function path analysis of muscle function on myofascial meridians. Method: Seven male students (mean age: $22{\pm}3.46years$; mean mass: $72.71{\pm}8.19kg$; mean height: $174{\pm}4.39cm$) without a history of musculoskeletal system symptoms or injuries were recruited for this study. The measurement muscle of the myofascial line was selected along with the muscle presented in "anatomy trains (Thomas W. Myers. 2014)", and the attachment of the surface EMG (Telemyo 2400T G2, USA) pad was determined according to "EMG analysis (Kim Tae Wan et al., 2013)". The subjects underwent maximum volumetric contraction of their fascia line end muscles three times in lying and standing postures and were subjected to the maximum number of contractions of the myofascial line muscle three times in the lying and standing postures. The sampling rate of the EMG signal was set to 1,000 Hz, and the bandwidth was 20 to 350 Hz. The activity of each muscle was quantitated using the Pearson correlation coefficient, and SPSS 22.0 was used for data analysis. Results: In myofascial meridians, a positive correlation in the myofascial connection and a negative correlation in the mechanical connection were observed. Conclusion: Muscles that show significant contract correlations with one another may be expected to be used as an effective clinical marker in muscle strengthening or relaxation therapy, and rehabilitative training. In this study, the correlation of total myofascial meridians may differ without consideration of functional posture. Future studies need to consider these points.

Purpose: This study aimed to investigate effect of ankle instability on peripheral muscle activation among female ballet dancers to provide information on the development of prevention programs for ankle injury rehabilitation. Methods: 32 female ballet dancers were randomly divided into two groups: experience ankle sprain group (n=16, age, $20.7{\pm}0.8years$, BMI $18.6{\pm}1.2kg/m2$) and non-experience ankle sprain group (n=16, $age=21.0{\pm}0.8years$, BMI $19.6{\pm}2.0kg/m2$). Activation of the peroneus longus, tibialis anterior muscle, and gastrocnemius during vertical landing, half pointe, and gait between the two groups were measured. Body composition analyzer was used to examine skeletal muscle mass and body fat mass. Results: A total of 32 patients were included. In the experience ankle sprain group (n=16: left sprain 14, right sprain 2), average ankle sprain injury occurred 7.5 months before the study. The average age of the dancers in the experience ankle sprain group and non-experience ankle sprain group was $20.7{\pm}0.8$ and $21.0{\pm}0.8years$, major period was $64.5{\pm}23.8$ and $71.6{\pm}25.8months$, BMI was $18.6{\pm}1.2$ and $19.5{\pm}2.0kg/m2$, respectively. No significant differences were found on body composition between the two groups (p>0.05). The experience ankle sprain group showed significantly lower tibialis anterior and peroneus longus muscle activation (p<0.5), while gastrocnemius muscle activation appeared to be significantly higher (p<0.05) during landing, half pointe, and normal gait. Conclusion: Ankle sprain can cause a decline in peripheral muscle activation and coordination, which increased the risk for repetitive ankle sprain in the future. Moreover, ankle peripheral muscle selective strength training, coordination program development, and application need to be considered to prevent ankle sprain.
