Objective: This study surveyed the perceptions of physical therapists on muscle re-education through visual feedback obtained from rehabilitative ultrasound imaging (RUSI). Design: Survey. Methods: For this study, 500 physical therapists who participated in a refresher training held by the Seoul City Association in March 2015 were selected for a questionnaire-based survey. Subjects were randomly selected targets physiotherapists who participated in a refresher training.The questionnaire had 21 items in total. Questions 1 to 15 could be answered by everyone. However, questions 16 to 21 could be answered only by people who used RUSI. Results: The majority of respondents were aged 20 to 30 years. Respondents in their twenties, thirties, forties, and fifties accounted for 32.4%, 40.2%, 21.9%, and 5.6%respectively. Therapists with careers spanning one to 5 years accounted for 27.8%, while those with careers spanning 5 to 10 years and 10 to 15 years accounted for 34.6% and 17.0%, respectively. Those with careers over 20 years accounted for 9.2%. The types of work have not been various including work related to the nervous system (49.0%), the musculoskeletal system (41.5%), sports (0.7%), juvenile physical therapy (4.2%), and others (4.6%). Conclusions: In this study, we examined the perceptions of physical therapists on rehabilitation ultrasound imaging used in muscle re-education. We also examined how to use this technique. Many therapists who participated in the refresher training were found to be unaware of RUSI. In the future, further investigations on RUSI for muscle re-education are required through refresher training or training lectures at the national level.

Purpose: The purpose of this study was to figure out how PAP (Post-Activation Potentiation) phenomenon affects short-term performance efficiently. Methods: This study was conducted with 18 Taekwondo athletes and 16 healthy adults. By using isokinetic dynamometer, two different intervention, TDP (Top-down program) and BUP (Bottom-up program), were performed to measure isokinetic parameter; (peak torque: PT, total work: TW, average power: AP, and average torque: AT) of knee extensor for intragroup, intergroup comparison and two-way ANOVA. Results: The Taekwondo athletes group showed statistically significant differences in all isokinetic parameters PT, TW, AP, and AT after TDP (p<0.05). However, in the healthy adult group, the difference in isokinetic parameters according to the exercise sequence was not statistically significant. (p>0.05). PT and TW at TDP were statistically significant (p<0.05) when the rate of change in TDP and BUP was compared and analyzed considering the difference in physical ability between the Taekwondo athlete group and the healthy adult group. However, AP and AT were not statistically significant. Finally, when examining the interaction between the two groups and two exercise sequence according to isokinetic parameters, only TW (p<0.05) showed a statistically significant interaction, while PT (P=0.099), AP (P=0.103), and AT (P=0.096) did not. This study suggests that short-term performance can be improved through the PAP phenomenon when TDP is applied to the Taekwondo group. Conclusion: According to our result, for Taekwondo athletes, if the goal is to improve short-term performance just before the main game, we suggest a training program through TDP.

PURPOSE: Flexibility and range of motion are very important factors in sports performance, rehabilitation, and musculoskeletal pain. The purpose of this study was to measure the effects of cupping therapy on flexibility, muscle activity, and pain threshold of hamstring muscle compared to passive stretching in healthy subjects. METHODS: Thirty healthy subjects were randomly assigned in a crossover design to cupping therapy and passive stretching. Subjects were tested to compare their effects according to the intervention such as Passive range of motion (PROM) (straight leg raising) and active range of motion (AROM). And algometer (pain) testing and MVC assessment using EMG were performed as dependent variables. RESULTS: The cupping therapy group and passive stretching group showed significant differences in all variables including PROM (p=.00, p=.00), AROM (p=.00, p=.03), Pain Threshold (p=.03, p=.08), Semitendinosus MVC (p=.01, p=.00), and Biceps femoris MVC (p=.01, p=.16). There were no significant differences between the two groups in all variables. CONCLUSION: These findings of this study suggested that cupping therapy has as much positive effect on flexibility, pain threshold, and muscle contraction as passive stretching. Also, it is more convenient and easier to work on patients than passive stretching. Therefore, cupping therapy should be considered as another option to treat range of motion, pain, and muscle activity in the clinical field.

PURPOSE: This study examined the incidence, location, and characteristics of sports injuries according to the position in Korean female national field hockey athletes. METHODS: Eighteen female national field hockey athletes (two goal keepers, five forwards, six midfielders, and five defenders) who trained at the national training center between January 2018 and December 2018 were enrolled. The event, position, and location of injury were recorded per IOC's daily injury reports form. The incidence of sports injuries was examined with the 95% confidence interval (CI), and the difference in the incidence of injury according to the position was presented as the rate ratio (RR). Moreover, differences in the location of sports injury according to the position were examined using χ2 tests. RESULTS: A total of 92 sports injuries occurred among field hockey players, with an incidence of 6.47 cases per 1,000 hours of training (95% CI 4.98-7.96). In addition, 29.12 cases of injuries occurred per 1,000 exposures (95% CI 23.17-35.07), and the incidence of injury was highest among the defenders, followed by forwards, midfielders, and goal keepers. The most common location of sports injury was the lower extremity, followed in order by the trunk, upper extremity, head, and neck, and there were significant differences in the location of the sports injury according to the position (p=.046). In addition, lumbar spine/lower back, thigh, ankle, lower leg, knee, and foot/toe were common sites of sports injury among female field hockey players. CONCLUSION: These results provide a baseline for predicting sports injuries in athletes during games, and would provide useful information for developing performance enhancement and injury prevention programs.

Purpose : This study compared the differences in power and agility of athletes in each sports using visual response speed test (VRST) scores after conducting 10 weeks of body stability exercise (BSE) on elementary school athletes in handball, football, volleyball and conducted a post-hoc test on the measured values. The subjects of this study were baseball (n=27), taekwondo (n=22), and football (n=23) athletes with at least two years of athletic experience. A total of 72 elementary school athletes were measured by VRST after 10 weeks of BSE under the same conditions. Methods : For VRST measurement of the upper extremity, the right and left hands were alternately touched in the order the blazepod equipment lights were turned on. The number of touches for 15 seconds and response touch were measured. In the case of the measurement of lower extremity the left lower extremity was measured first when the Blaze pod equipment light came on. The average value was obtained by measuring 3 times using a measurement sensor with the position indicated in order to measure the upper arms and legs the same. Results : This study confirmed homogeneity among sports and that VRST improved after implementing BSE for sports. However, no statistically significant difference was identified when comparing VRST improvements between sports, and post-hoc test results showed no significant differences either. Conclusion : After applying the BSE program under the same conditions for 10 weeks to elementary school students who can improve their power and agility the most, the results of the examination using the Blaze pod showed that the power and agility of baseball, taekwondo, and soccer players were similarly improved. From the fact that there was no significant difference among sports, it could be inferred that the BES training program could improve VRST without being limited to some sports.

Purpose: This study was evaluated the effects of nucleoplasty and chemonucleolysis, as interventional treatments for herniated intervertebral disc disease, on spinal tissues. Methods: Nucleoplasty using plasma beam and chemonucleolysis with collagenase were conducted on the spinal motion segments that were dissected from of human cadaver spine under fluoroscopic guidance. After the procedure, the intervertebral discs were transected, and the changes in gross findings were examined. Subsequently, the influence of the procedure on the nucleus pulposus, annuls fibrosus, and endplate was analyzed through a pathologic examination. Results: Nucleoplasty was confirmed to eliminate the local range of tissues in nucleus pulposus according to the procedure tract and to not affect other tissues. In chemonucleolysis, we found that collagenase diffused from the surgical site within the nucleus pulposus and was not present in the annulus fibrosus and endplate. Conclusions: The clinically-used interventional treatments that were investigated here were not found to do not cause additional damage to areas other than those targeted.

Background: The oxygen uptake efficiency slope (OUES) is the most important index for accurately measuring cardiopulmonary function in patients with acute ischemic heart disease. However, the relationship between the OUES variables and important cardiopulmonary function parameters remain unelucidated for patients with acute ischemic heart disease, which accounts for the largest proportion of heart disease. Objects: The present cross sectional clinical study aimed to determine the multiple relationships among the cardiopulmonary function variables mentioned above in adults with acute ischemic heart disease. Methods: A convenience sample of 110 adult inpatients with ischemic heart disease (age: 57.4 ± 11.3 y; 95 males, 15 females) was enrolled at the hospital cardiac rehabilitation center. The correlation between the important cardiopulmonary function indicators including peak oxygen uptake (VO₂ peak), minute ventilation (VE)/carbon dioxide production (VCO₂) slope, heart rate recovery (HRR), and ejection fraction (EF) and OUES was confirmed. Results: This study showed that OUES was highly correlated with VO₂ peak, VE/VCO₂ slope, and HRR parameters. Conclusion: The OUES can be used as an accurate indicator for cardiopulmonary function. There are other factors that influence aerobic capacity besides EF, so there is no correlation with EF. Effective cardiopulmonary rehabilitation programs can be designed based on OUES during submaximal exercise in patients with acute ischemic heart disease.
