이 연구의 목적은 발목관절의 발등굽힘 가동범위에 따라 동적 균형능력을 평가하는 Y-Balance Test와의 관계를 규명하고자 하였다. 이 연구 결과 HADR군에서 PLRD(P<.05)와 CS(P<.01)에서 유의한 차이가 나타났으며, 발목관절 발등 굽힘의 가동범위와 뒤안쪽 도달거리(PMRD), 뒤가쪽 도달거리(PLRD) 및 종합점수(CS)만 중등도의 유의한 상관관계가 나타났다. 따라서 발목관절 발등굽힘의 감소는 균형능력 능력을 감소와 관련이 있으며 축구선수의 손상의 예방하기 위해서는 정기적인 발목 관절가동범위를 평가가 필요한 것으로 생각된다.

The purpose of this study to compare the effect of physical therapy interventions on the improvement of ankle joint range of motion with stroke patients. Total subjects were 45 stroke patients, who were divided into a group using inclined boards(n=15), a group of receiving stretching(n=15), and a group of receiving joint mobilization(n=15). The experiment was performed for 8 weeks. The plantar flexion showed significant differences both groups and by periods. The dorsiflexion showed significant differences between groups and by periods, and the group in changes within groups by periods. This study found that stretching and joint mobilization are effective as an intervention method to increase the range of motion on ankle joint. Future study is expected to investigate other effects of increased ankle range of motion in stroke patients.

The purpose of this study was to determine the relationship with the Y-Balance Test, which evaluates dynamic balance ability according to the ankle joint dorsiflexion range of motion in a non-weight bearing posture. This study involved 27 male soccer players who regularly participate in the K3 League with more than 10 years of soccer experience. The Pearson Rank Correlation Coefficient was used to verify the relationship between ankle joint dorsiflexion and dynamic balance ability. The results of this study showed significant differences in PLRD (P<.05) and CS (P<.01) in the HADR group. A significant correlation between ankle joint dorsi-flexion range of motion and severity was found only in PMRD, PLRD, and CS. Therefore, a decrease in ankle joint dorsi-flexion is associated with a decrease in balance ability. In order to prevent injuries in soccer players, it is believed that regular evaluation of ankle joint range of motion as well as training to improve knee and hip joint strength and proprioception are necessary.

The purpose of this study was to investigate the effects of a acute ankle mobility exercise (AE) program on the range of motion and pain levels associated with chronic ankle instability (CAI). Twenty adult women with an average score of 24 or less on both sides in the ankle instability questionnaire were selected and divided into two groups: the Ankle Mobility Exercise Program group (AE, n=10) and the control group (CON, n=10). The AE treatment involved a one-time, 20-minute exercise session for each ankle, conducted separately on the left and right ankles, to examine the response to a acute exercise. Measures of ankle instability, pain, and ankle range of motion were evaluated before and after the treatment. In the AE group, which underwent the AE program, a significant decrease in pain was observed post-AE compared to pre-AE (p<.01). In addition, an increase in dorsiflexion was observed in the AE group post-AE compared to pre-AE following the AE program(p<.05). These results suggest that a acute AE program can effectively alleviate some aspects of ankle instability by improving ankle pain and range of motion in adult women with chronic ankle instability (CAI).

The purpose of this study was to analyze the effects of flossing band exercise on the range of motion and vertical jump for taekwondo demonstration athletes with ankle functional instability. The subjects of this study were 21 male Taekwondo Demonstration Team athletes enrolled at D University. They were divided into functional ankle instability group(FAIG, n=7), mild ankle instability group(MAIG, n=7), and ankle stability group(ASG, n=7). All groups performed a acute flossing band exercise program. The results of this study are as follows; dorsi flexion(p<.01), inversion(p<.01), eversion(p<.05) and vertical jump(p<.01) were significantly increased in the FAIG. Flossing band exercise of Taekwondo demonstration team with FAI increased joint range of motion and vertical jump. Therefore, it was confirmed that it could be an intervention that can improve performance and reduce the risk of ankle injury.

Transcutaneous electrical nerve stimulation and interferential current therapy were applied to the plantar flexor of the stroke patients, and the immediately effects on gait and ankle ROM were investigated. TENS group (n=15) and ICT group (n=15) were applied to the paretic side plantar flexor, respectively. After 60 minutes of application, evaluation of the gait and passive ankle dorsiflexion range of motion (ROM) using smartphone. After 60 minutes of application, immediate post evaluation was carried out. Two electrotherapy methods showed a significant increase in gait speed, cadence, and ankle ROM. Two electrotherapy methods were intervention methods that could increase the gait and ankle ROM of stroke patients. More subjects will be needed to pinpoint differences between the two electrotherapy methods.

The objective of this study is to verify the effects of the application of flossband to the ankles of healthy adults on the functional range of ankle and walking ability. Total 20 people participated in the experiment, and through the randomization, one foot was set up as experimental side while the other foot was set up as control side. To analyze the two factors(before/after intervention/experimental side and control side), the two way-repeated ANOVA was conducted. The significance level was set up as 0.05. In the results of this study, compared to the control side, the experimental side showed significant increase in WBLT and heel strike(p=.05). In the test before/after intervention, the experimental side showed significant increase in WBLT, heel strike, and toe off(p=.05). The control side showed significant increase in toe off(p=.05). Thus, the application of floss band on ankle joint performed in this study would be helpful for improving the functional range and walking ability in the sports & rehabilitation field.

The purpose of the study was to compare the differences among phases accoring to the gait time on the heel height during gait, investigate the effect on ROM of the lower limb on gait time. Ten female college students in their 20s participated in the study, and variables were calculated through 3D gait analysis on height of heel. As a statistical method, one-way ANOVA was performed for the differences between the three heel heights, and multiple regression analysis was performed to determine the effect of gait time on the ROM. As a result of the study, phase 2, the higher the heel, the longer the gait time, but phase 3, the higher the heel, the shorter the gait time. As a result of analyzing the effect of gait time on the ROM of the lower limb, in phase 2, the greater the ROM for the ankle and knee joint in 1 cm, and for the ankle joint in 5 cm, the longer the gait time. In phase 3, the greater the ROM for the hip joint in 1 cm, the longer the gait time, and the smaller the ROM for the ankle joint in 10 cm, the longer the gait time. Therefore, in the case of high-heeled shoes, it is suggested that the control of the ankle joint is important.

The effect of kinesio taping in patients with common peroneal nerve paralysis (PNP) have not been investigated. This purpose of this study was to evaluate the effects of kinesio taping on patients with common PNP. Ten subjects who had common PNP were included in this study. Kinesio taping was applied to the ankle joint (direction of dorsiflexion and eversion). The measurements were by manual muscle test (MMT; tibialis anterior, peroneus longus), active ROM (ankle dorsiflexion, eversion), pain (visual analogue scale (VAS), pressure pain threshold (PPT)), and balance (one leg standing). Subjects were assessed at baseline and 8 weeks of intervention. In the results, all subjects showed improvements in MMT, active ROM, Pain and balance at the 8-week. These findings are considered to be effective in applying kinesio taping on ankle joint in common PNP patients.

이 연구의 목적은 노인들 중, 넘어지는 사람들(fallers)과 안 넘어지는 사람들(nonfallers)의 경부, 체간, 하지의 관절가동범위를 측정하여 비교하는 것이다. 본 연구대상은 남자 6명, 여자 22명, 나이 65세에서 88세의 노인으로 독립적으로 활동할 수 있는 사람들을 두 개의 집단으로 한 사람씩 면접을 통해 분류하였다. 대상자 선정 이전 일년 동안 한번 이상 넘어진 경험이 있는 사람들을 넘어진 사람들로 규정, 그리고 넘어진 경험이 없는 사람들을 안 넘어진 사람들로 정의하였다. 관절가동범위는 각도기로 측정하였고 미국 정형외과 학회(American Academy of Orthopaedic Surgeons)의 표준화된 가동 범위 측정방법을 사용하였다. 넘어진 사람들과 안 넘어진 사람들의 연구 결과의 차이를 알아보기 위하여 양측 독립성 t-검정을 사용했다. 연구결과, 넘어진 사람들과 안 넘어진 사람들간의 관절가동범위 중 흉요부의 굴곡, 신전, 우측굴곡, 좌측굴곡, 그리고 우측회전과 좌측회전, 고관절부의 신전, 내전, 외측회전과 내측회전, 그리고 족관절의 배굴에서 유의한 차이가 있었다. 이와 같은 결과는 체간, 고관절부 그리고 발목의 유연성이 노인들의 균형을 유지하는데 영향을 준다고 말할 수 있다.
