Purpose: This study examined the effects of upper- and lower-limb coordinated exercise with proprioceptive neuromuscular facilitation (PNF) on stroke patients' recovery of their balancing and walking abilities. Methods: This study was conducted with 30 patients aged at least 60 years and diagnosed with stroke. The patients were randomly assigned to either a PNF upper- and lower-limb coordinated exercise group of 15 patients or an aero-step balance exercise group of 15 patients. To test the subjects' balancing and walking abilities, balancing ability tests and 10-m walking speed tests were conducted before and after the interventions. The patients performed their respective exercises for 30 minutes per session, three times per week for four weeks. The PNF exercise group performed six stages of exercise consisting of a combination of PNF patterns such as sprinting, skating, and striking. The six stages (right striking, right skating, right sprinting, left striking, left skating, and left sprinting) were performed continuously with a rest period of 1 min. after training for 4 min. The exercises for the aero-step balance group consisted of balancing in a two-leg standing position, weight shifting in a two-leg standing position, one-leg standing, squat exercises, marching in place, and squatting on an aero step. Results: The PNF exercise group showed significant improvements in their balancing ability evaluations compared to the aero-step balance group and also showed significant improvements in their 10-m walking speed tests. Conclusion: Based on the results of this study, PNF upper- and lower-limb coordinated exercise resulted in clinical improvements of stroke patients' balancing and walking abilities. Therefore, this type of exercise is recommended as a clinical intervention for the recovery of stroke patients' lower-limb function. Future studies should be conducted with longer intervention periods and more subjects to generalize the study results.

Purpose: This study aimed to examined the effects of upper and lower limb coordinated exercise of proprioceptive neuromuscular facilitation (PNF) on static and dynamic balance ability. Methods: The subjects of this study were 18 patients who had been diagnosed with a stroke and hospitalized and who had received rehabilitation treatment at D rehabilitation hospital located in J city. They were randomly and equally assigned to a PNF upper and lower limb coordinated exercise group and an ordinary central nervous system development and treatment group, and they conducted exercises for eight weeks. They carried out exercise three times per week, for 30 minutes per each time. After each four minutes of exercise, each participant was given a and rest for one minute after exercise for four minutes was given. In order to test the subjects' static and dynamic balance ability and their dynamic balance ability, frailty and injuries,: a cooperative studyies of intervention techniques (FICSIT-4) test, a four- step square test (FSST), a timed up and go test (TUG), and a TWT3M tests wasere conducted before and after the exercise. Descriptive statistics were taken for the general characteristics of the subjects, and an independent t-test was conducted both before and after the exercise in order to examine differences between the two groups before and after the exercise were conducted. The A statistical significance level was set at p= 0.05. Results: In all the tests (of FICSIT-4, FSST, TUG, and TWT3M), both the experimental group and the control group saw more improved results, but the experimental group's results were significantly higher than those of the control group, and the size of the effects was larger in the experimental group than in the control group, with statistically significant results. Conclusion: PNF upper and lower limb coordinated exercise applied to chronic stroke patients produced brought significant results in static and dynamic balance ability. PNF and is considered as an important intervention program to improve stroke patients' balance ability.

Purpose: This study aimed to examine the effects of proprioceptive neuromuscular facilitation (PNF) upper and lower limb coordinated exercises on balance in elderly women. Methods: The study was conducted with 27 elderly women who were at least 65-year-old. The subjects were randomly assigned to a PNF upper and lower limb coordinated exercise group consisting of 14 subjects and an aero step balance exercise group consisting of 13 subjects, and the exercises were performed for 30 minutes, three times per week, for eight weeks. One Leg Stance Tests (OLST), Functional Reaching Tests (FRT), Four Square Step Tests (FSST), and Timed Up and Go (TUB) tests were conducted before and after the exercises to evaluate the subjects' static balance ability and dynamic balance ability. Among the collected data, the subjects' general characteristics were evaluated using descriptive statistics, the intra-group differences of the test results before and after the intervention were compared using paired sample t-tests, and the inter-group differences in the results before and after the intervention were evaluated using independent sample t-tests. The statistical significance level was set to 0.05. Results: Among the OLST, FRT, FSST, and TUG tests, the experimental group showed positive FSST results that were statistically significantly greater than the control group; the results of the other tests were also more positive for this group, but the differences between the groups were not statistically significant. The magnitude of the effects for both groups was clinically significant. Conclusion: Since inter-limb coordinated exercises for PNF applied to elderly women were found to produce good results for both static balance ability and dynamic balance ability, these exercises can be used in exercise programs to improve balance in elderly women.

본 연구는 한 발 지지 유무에 따른 상하지 협응운동이 만성 뇌졸중 환자의 보행 능력에 어떠한 영향을 미치는지를 알아보고자 실시하였다. 만성 뇌졸중 환자 14명을 대상으로 하여 한 발을 지지하여 상하지 협응운동(주 3회, 4주간)을 적용한 군(n=7)과 한 발 지지없이 상하지 협응운동을 적용한 군(n=7)으로 무작위 배정하였다. 보행능력검사는 10MWT, F8WT를 이용하여 측정하였고, 동적균형능력검사는 FSST를 이용하여 측정하였다. 정규분포를 한 10MWT는 두 군의 측정시점에 따른 유의성 검정을 위해 이요인 분산분석을 실시하였다. 정규분포를 하지 않은 F8WT, FSST는 두 군의 측정시점에 따른 유의성 검정을 위해 Friedman 검정을 하였고, 두 군간 비교를 위하여 Mann-Whitney 검정을 실시하였다. 그 결과, 모든 측정에서 두군 모두 측정시점간 유의한 차이가 있었다. 본 연구의 결과로 보아 상하지 협응운동은 뇌졸중 환자의 보행 능력에 유용한 전략으로 사용될 수 있음을 증명하였다.
