Objective: To investigate the effects of training using a trunk control robot (TCR) system combined with conventional therapy (CT) on balance and gait abilities in persons with chronic stroke. Design: Two-group pretest-posttest design. Methods: Thirty-five subjects with chronic stroke were randomly assigned to either the TCR group (n=17) or the trunk extension-training (TET) group (n=18). Both groups performed CT for 30 minutes, after which the TCR group performed TCR training and the TET group performed trunk extension training for 20 minutes. Both groups performed the therapeutic interventions 3 days per week for 6 weeks. Balance ability was evaluated using the Berg Balance Scale (BBS), and the Timed Up-and-Go (TUG) test. Gait ability was measured using the 10 m Walk Test (10MWT) and the NeuroCom Smart Balance Master. Results: TCR group showed significant improvements in static balance (weight bearing) and dynamic balance (weight shifting speed, weight shifting direction, BBS, and TUG), 10MWT, gait speed, and step width (p<0.05); step length was not significant. The TET group showed a significant partial improvement of dynamic balance (weight shifting speed, weight shifting direction, BBS, and 10MWT (p<0.05), but the improvements in static balance, TUG, gait speed, and step width and step length was not significant. Additionally, significant differences in static balance, dynamic balance (weight shifting speed, weight shifting direction, BBS, and TUG), 10MWT, gait speed, and step width were detected between groups (p<0.05). Conclusions: TCR training combined with CT is effective in improving static and dynamic balance, as well as gait abilities in persons with chronic stroke.
This study explored the feasibility of utilizing an SWCNT-coated fabric sensor for the development of a wearable motion sensing device. The extent of variation in electric resistance of the sensor material was evaluated by varying the fiber composition of the SWCNT-coated base fabrics, attachment methods, number of layers, and sensor width and length. 32 sensors were fabricated by employing different combinations of these variables. Using a custom-built experimental jig, the amount of voltage change in a fabric sensor as a function of the length was measured as the fabric sensors underwent loading-unloading test with induced strains of 30 %, 40 %, and 50 % at a frequency of 0.5 Hz. First-step analysis revealed the following: characteristics of the strain-voltage curves of the fabric sensors confirmed that 14 out of 32 sensors were evaluated as more suitable for measuring human joint movement, as they yield stable resistance values under tension-release conditions; furthermore, significantly stable resistance values were observed at each level of strain. Secondly, we analyzed the averaged maximum, minimum, and standard deviations at various strain levels. From this analysis, it was determined that the two-layer sensor structure and welding attachment method contributed to the improvement of sensing accuracy.
The right hip adbuctor musculature has been reported to demonstrate 'stretch weakness' attributable to chronic elongation imposed by standing posture common to right-handed healthy persons. Kendall and associates have described the concept of 'stretch weakness'. The purpose of this study was to assess isometric hip abduction torque and surface electro-myographic activity (using MYOMED 432) in a sample of 40 healthy right-handed persons (20 male, 20 female), all of whom agreed to participate in the study, and compare side difference in the hip abductor musculature. In order to assure the statistical significance of the results, the paired t-test was applied at the .05 level of significance. The results were as follows : 1. The difference in apparent leg length of right and left legs was significant at the .05 leve1. 2. There was a significant difference between right and left pelvic height (standing position) at the .005 level measurements, and scapula height at the .05 level. 3. Power measurements and action potentials of right hip adbuctor were greater than the left hip adbuctor regardless of the range of joint motion (inner range, outer range). 4. The difference in muscle power and action potentials according to inner or outer range of both hip abductor were significant at the .05 level. 5. In supine during active left hip abduction, the appearance of action potentials in the right hip abductors is indicative of contra-lateral effect (p<.005). These results suggest : In healthy right-handed persons. the apparent leg length on the right is longer than on the left, and pelvic height is elevated on the right side. Muscle torque and muscle action potentials of the right hip adbuctor art higher than those of the hip abductor in the lengthened position. Therefore, the results in this study are contrary to Kendall's. This type of study should be carried out in many physical therapy departments.

PURPOSE: This study compared the body composition according to the sport of short-distance and middle & long-distance athletes to identify the factors that affect the body composition. METHODS: Forty-eight athletes selected as youth national athletes in 2019 participated in the study. The study participants measured the length of the lower extremities, body composition, and anaerobic ability. An independent sample t-test was conducted to compare the body composition according to the event. In addition, the Pearson correlation was performed to identify the factors that influence the body composition. RESULTS: The leg length of the Short and Middle & long-distance athletes were similar (p = .584). On the other hand, there were differences in the body fat percentage (p = .001), lean percentage (p = .001), and BMI (p = .001). In addition, the body fat percentage was correlated with the lean body mass (r = .419) and BMI (r = .447). Furthermore, the lean body mass was correlated with the BMI (r = .849) and the peak power (r = .662) and mean power (r = .686) of the anaerobic capacity. Moreover, the BMI was correlated with the peak power (r = .490) and mean power (r = .543) of the anaerobic capacity. The peak power of the anaerobic ability was correlated with the mean power (r = .931). CONCLUSION: The body composition differed according to the sport. The body fat percentage correlated with the lean body mass and the BMI. The lean body mass correlated with the BMI, peak power of anaerobic ability, and mean power. The BMI correlated with the anaerobic capacity.

The physical characteristics of the major varieties of perilla were analyzed to use as basic data for the design of a high-quality, high-efficiency perilla cleaner and stone separator. Because the size, thousand-grain weight, angle of repose, angle of friction, bulk density and terminal velocity of perilla have significant differences according to the perilla variety, the different of characteristics by variety should be considered for performance improvement of a perilla cleaner and stone separator. Therefore the cleaner and stone separator using a sieve could be improved by the application of a detachable sieve or by using equipment such as a 2 - 3 stage sieve and regulating the slope. Moreover, because differences in the terminal velocity occur due to the differences in the size and thousand-grain weight according to the perilla variety, a blower with an adjustable fan speed was considered for the design of the improved cleaner. Additionally, it was shown that the length of perilla has the greatest correlation based on a comparison of the coefficients of the other characteristics. Accordingly, the length of perilla could be used as a major factor for the fine adjustment and parts replacement of the device. These results can be used as basic data for a high-quality, high-efficiency perilla cleaner and stone separator. In the future, the development of the machine and follow-up studies based on the basic data are needed to determine the optimized operating conditions and mechanism of action.

Purpose : Lymphedema is a common complication in mastectomy patients and is usually characterized by pain, swelling, and limited range of motion (ROM) in the arm. Electromyostimulation (EMS) is widely used for the rehabilitation and recovery of subjects with various neuromusculoskeletal disorders after breast cancer. However, EMS has not yet been used in many Pilates exercises. This study was aimed at comparing the effects of instrument Pilates integrated with EMS on pain, lymphedema, and ROM of the upper extremity (UE) in breast cancer subjects after mastectomy. Methods : Nine female breast cancer subjects who had undergone mastectomy participated in the study. The subjects underwent instrument Pilates with EMS (experimental group) or instrument Pilates only (control group). Pain, lymphedema, and ROM of the UE were measured using the visual analog scale (VAS), the circumference length of the UE, and the ROM of the UE. The Wilcoxon signed-rank test was used to compare the pain, lymphedema, and ROM of the arm before and after the intervention, and the Mann-Whitney U test was used to compare the two groups. The statistical significance level was set to p < .05. Results : In the experimental group, there were significant differences in pain (p<.05) and UE circumference (p<.05) before and after intervention. However, there was no significant difference between the two groups in VAS (p>.05) or circumference length of the UE (p>.05). There was one significant difference between the groups in terms of internal rotation of the ROM of the UE (p<.05). Conclusion : These results show that instrument Pilates exercises combined with EMS may positively affect the internal rotation of the ROM of the UE in breast cancer patients after mastectomy, thus contributing to existing knowledge about instrument Pilates using EMS for the effective management of in breast cancer subjects after mastectomy.
Background: This study was to investigate effects of narrow squat exercise according to ankle angle of Toe in 10° and Toe out 10° on women with genu varum. Design: Randomized Controlled Trial or Cross-sectional Study. Methods: 30 adult women with genu varum participated in this study. All subjects were randomly assigned to 15 people of narrow squat exercise in ankle angle of Toe in 10° group (TI) and 15 people of narrow squat exercise in ankle angle of Toe out 10° group (TO). The narrow squat exercise program was conducted three times a week for six weeks. The distance between the knees was measured by using Digital Vernier Caliper. The quadriceps angle (Q-angle) was measured by using Goniometer. The stride length and propulsion were measured through G-Walk Results: Both TI and TO groups showed effective significant differences in distance between the knees, Q-angle, and propulsion (p<.05). There was no significant difference in stride length (p>.05). Left leg propulsion was found to be significantly more effective in TI group than in TO group (p<.05). Conclusion: These results suggested that narrow squat exercise according to ankle angle of toe in 10° and toe out 10° was effective for genu varum. However, compared to TO group, TI group was more effective in gait propulsion. It is considered that narrow squat exercise in ankle angle of Toe in 10° can be suggested as an effective intervention method for women with genu varum.
