PURPOSE: The purpose of this study was to propose clinical criteria to differentiate patients who are able to perform the step-through-step gait pattern in chronic stroke patients. METHODS: Sixty patients with chronic stroke patients participated this study. To differentiate patients who could perform the step-through-step gait pattern, age, gender, and causes of stroke were noted, a Chedoke-McMaster (CM) damage list, Fugl-Meyer (FM) assessment scales and the Berg Balance Scale (BBS) were determined. A 10 meter gait test and Timed Up and Go (TUG) test were conducted to determine the differences in gait speed and dynamic balance between patients walking with or without canes in the step-through-step gait pattern group. RESULTS: There was no significant statistical difference in age, gender, and stroke type between all subjects. There were significant differences in the CM scale for postural and lower extremities, and FM scale for lower extremities and BBS. The dynamic balance ability and gait speed showed significant differences between the subjects in the step-through-step gait pattern with or without a cane during gait. CONCLUSION: CM and FM scales for the lower extremities and postural control, as well as BBS scales, can be used as criteria to differentiate patients who are able to perform the step-through-step gait pattern. These results can also be used to provide beneficial information to patients that are walking with canes.

This study aimed to evaluate the effect of a weekly circuit-group exercise program on functional performance, flexibility of the trunk and lower extremities, and balance in individuals with chronic stroke who are living in a community. Thirteen community-living individuals (eleven males and two females) with chronic stroke participated in this study. The group exercise program was set up as a weekly circuit application with four stations aiming to strengthen the muscles, increase endurance, improve flexibility, and enhance functional capacity. The average duration of a session was an hour, and the sessions were conducted once a week for six months for a total of 24 sessions. Assessments for functional performance, flexibility of the trunk and lower extremities and balance were conducted four times: before treatment, after one month of treatment, after four months of treatment, and after six months of treatment. There were significant improvements in functional performance and flexibility of the trunk and lower extremities in the given time frame. No significant improvement was observed in balance ability. The findings suggest that a weekly circuit-group exercise program has some benefits in terms of managing the physical symptoms of individuals with mobility problems after stroke. Therefore, this program can be adapted and employed as a community-based rehabilitation program for such patients. Further studies with various community-based treatments will be conducted to validate these findings.

배경: 죽상동맥경화성 하지동맥폐쇄증은 대부분의 경우에 전신 동맥 경화증이 동반되며 사망의 원인으로는 주로 반 이상이 관상동맥질환에 의하여 발생한다. 또한 만성 동맥폐쇄증 수술 후 수술 사망 원인은 심장 합병증에 의한 사망이 가장 빈번한 것으로 알려져 있다. 특히 죽상동맥경화성 하지동맥폐쇄증 환자에게 과거에 심질환이 없거나 허혈성 심질환의 주증상이 없던 경우에 수술 후 높은 사망률을 보이는데 이런 이유로 이 환자군에 대한 관상동맥질환의 동반 여부에 대한 수술 전 검사의 필요성이 제기되는 바이다. 대상 및 방법: 2001년 2월부터 2004년 10월까지 죽상동맥경화성 하지동맥폐쇄증으로 입원한 환자 중 과거력상 심질환이 있었거나 허혈성 심질환이 주증상이었던 환자를 제외한 52명의 환자를 대상으로 관상동맥조영술과 하지동맥조영술을 동시에 시행하여 죽상동맥경화성 하지동맥폐쇄증에서 관상동맥질환의 동반 빈도를 파악하였다. 또한 죽상동맥경화성 하지동맥폐쇄증의 중증도를 나타내는 AVO score와 동반된 관상동맥질환과의 상관관계를 비교하였다. 결과: 죽상동맥경화성 하지동맥폐쇄증에서 관상동맥질환을 동반한 경우는 63%(33명)였고, 고령, 당뇨, 고혈압, 흡연력, 고콜레스테롤혈증 등의 동맥 경화증의 위험인자 중 고령과 고혈압이 관상동맥 질환을 동반하는 죽상동맥경화성 하지동맥폐쇄증의 중증도와 통계학적인 의미를 보였다. AVO score가 높을수록 관상동맥 질환의 동반이 흔하였고 관상동맥질환의 중증도 역시 증가되는 소견을 보였다. 관상동맥질환이 동반된 죽상동맥경화성 하지동맥폐쇄증 환자에서 관상동맥 우회술 및 관상동맥 중재적 시술을 병합하여 하지동맥 우회술을 시행한 경우, 하지동맥 우회술의 단독시행에 비해 사망률이 현저히 감소하였다. 결론: 과거력상 심질환이 없거나 허혈성 심질환의 주증상이 없는 죽상동맥경화성 하지동맥폐쇄증 환자에서 특히, 고령, 고혈압, AVO score가 높은 환자군에서는 수술 전 관상동맥조영술을 시행하여 동반되는 관상동맥 질환을 파악한 뒤 이에 대한 적극적인 치료를 시행하여야 한다.

Purpose: The purpose of this study was to identify the effects of Ankle Pump Exercise on lower limb edema and pain of operating room nurses. Methods: This research was arranged on the basis of the nonequivalent control group pre-post test design. The participants were 41 nurses working in the operating room in 'S' hospital in Seoul and 'H' hospital in Guri City, Korea. Data were collected from August 20 to September 30, 2012. Edema of the lower extremities was measured in terms of the girths of ankles and calves. Pain of the lower extremities was measured in terms of VAS (Visual Analogue Scale) for pain. The data were analyzed by frequency, percentage mean, and standard deviation, using the chi2(p) and t-test, repeated measures ANOVA, and a paired t-test. The SPSS Win 20.0 program was used for analysis. Results: Hypothesis 1 - "There are significant differences in lower extremity edema between the experimental group and the control group." - was partially supported. Hypothesis 2 - "There are significant differences in lower extremity pain between the experimental group and the control group." - was supported. Conclusion: The results of this study demonstrate positive practical effects of the Ankle Pump Exercise in reducing the circumference of both ankles, reducing the circumferential edema of both calves, and alleviating the pain of nurses in the operating room. Based on these findings, application of the Ankle Pump Exercise can be considered as an effective method to prevent nurses' health problems in the lower extremities that can be induced by their work during surgical operations.

With an increasing aging population and improved standards of living, more attention has been paid to health. Although walking exercise is known as an aerobic exercise, it imposes repeated and continuous impacts on the joints of the lower extremities. Therefore, when overweight gives a burden to the lower extremity or there is a joint disease, exercise limit occurs. The articular cartilage, weakened with age, also makes it difficult for the elderly to perform walking exercises. Accordingly, this study conducted a comparative analysis between regular walking using only the lower extremity and Nordic walking, which has been known as stable. For analysis, electromyography (EMG) was performed and the ground reaction force of the upper and lower extremities were measured in the same exercise. Integrated EMG (iEMG) revealed that the upper extremity muscles were more active in Nordic walking than in regular walking, where lower extremity muscles were relatively more inactive. In addition, when EMG measurements were performed at each measurement point during walking exercise, the pattern was different. Nevertheless, the result was the same as in iEMG. The load that occurs in each exercise was measured using the ground reaction force system. As a result, Nordic walking had a lower load than regular walking. Therefore, it was found that Nordic walking minimized the load on the lower extremities owing to the effect of whole-body exercise and was a safer and more efficient exercise method.

The purposes of this study were to determine the effects of rehabilitation programs on functional performance of the lower extremities and whether additional therapeutic exercise with routine rehabilitative therapy improves functional performance more than just routine rehabilitative therapy by it self for inpatients who have suffered a stroke with below moderate severity within 3 to 6 months after the onset of the stroke. Fifty-eight subjects were divided into two groups. Group I was given routine rehabilitative therapy and group II was given additional therapeutic exercise along with the routine rehabilitative therapy. Each group received 6 weeks of rehabilitation. The timed get-up and go test (TUG), the Fugl-Meyer score (FMS), functional independence measure (FIM), functional reach (FR), gait velocity (GV), and the strength of knee extensor and flexor were selected to measure effect of rehabilitation programs. The main results were measured and analysed at baseline, 3 weeks, and 6 weeks after the start of the rehabilitation programs. The results revealed that all of functional performance of the lower extremities in 3 weeks after the start of the rehabilitation programs were significantly improved compared with before the rehabilitation programs in both groups. In 6 weeks, TUG, FIM, FR, GV, and the strength of knee extensor in group I, TUG, FMS, FIM, FR, GV, and the strength of knee extensor and flexor in group II were significantly improved compared with the results after 3 weeks. At 3 weeks after rehabilitation programs, group II made significantly greater gains in TUG, FR, GV, and the strength of the knee flexor compared to the group I. At 6 weeks, group II made significantly greater gains in TUG, FR, GV, and the strength of the knee extensor and flexor compared to the group I. In conclusion, rehabilitation programs for stroke patients within 3 to 6 months after stroke onset significantly contributed to improve functional performance of the lower extremities. It is desirable for improvement of functional performance of the lower extremities to perform additional exercise with routine rehabilitative therapy.

PURPOSE: The purpose of this study was to compare the lower extremities muscle activation between squatting exercise with gym ball and wall for improving muscle strengthening in lower extremities. METHODS: Participants were 21 university students (males 10, females 11) who didn't have any problem with orthopedic surgery. Participants performed squatting exercise with gym ball and wall. Squatting exercise with gym ball were performed using by gym ball behind back, and the gym ball were fixed in back and wall. We asked participants to push back the gym ball slightly to prevent fall of ball. Wall squatting exercise, we ask participants to contact their back in wall slightly in order to prevent trunk flexion during performed squatting exercise. Each squatting exercise had performed until knee joint were flexed at 60 degree, and maintained five seconds. We collected data from E.M.G of Biceps femoris, Gastrocnemius, Vastus medialis and lateralis, Tibialis anterior of lower extremity in isometric phase of knee joint angle 60 degree of each squatting exercise. We analysed data using by ANOVA and independent t-test of SPSS PC ver.20.0 in order to compare the muscle activation between squatting exercise with gym ball and wall. RESULT: All of lower extremities muscle activation showed more higher value in squatting exercise with gym ball than squatting exercise with wall, especially there was significantly difference of muscle activation in vastus medialis, tibialis anterior between squatting exercise with gymball and with wall. CONCLUSION: On comprehensively considering the results of the present study, we suggested that squatting exercise with gym ball was more effective method improving lower extremity muscle strengthening.
