This study aimed to investigate the effect of aquatic rehabilitation exercise therapy on static balance and gait in patients with early Parkinson"s disease. The subjects of the study were 12 patients with early Parkinson"s disease. Aquatic rehabilitation exercise therapy was conducted 3 times a week for 12 weeks from June to August 2021. In the case of static balance, postural speed and postural speed variables were measured using BioRescue equipment in the open-eye posture. In the case of gait, GaitRite equipment was used to measure the stride length, cadence, and velocity variables. One-way repeated ANOVA verification was conducted to verify changes between the above variables before participating in the aquatic rehabilitation exercise therapy, 6 weeks after participation, and 12 weeks after participation. Significant changes were observed in both static balance and gait (p<.05) of the 12 subjects after participating in the aquatic rehabilitation exercise therapy. This study confirmed that static balance and gait ability for patients with early Parkinson"s disease were improved after the 12-week aquatic rehabilitation exercise therapy. Therefore, it is believed that aquatic rehabilitation exercise therapy can be used as an alternative treatment for improving, treating, and preventing problems in the balance and gait functions of patients with early Parkinson"s disease.

본 연구는 다양한 좌석 높이에서 일어서기 훈련이 뇌졸중환자의 균형에 미치는 영향에 대해 알아보고자 연구를 실시하였다. 연구의 대상자는 뇌졸중환자 20명이며 무작위로 표준좌석 높이 그룹 10명과 낮아지는 좌석높이그룹 10명으로 분류하여 2019년 3월에서 6월까지 주 3회 6주간 훈련을 실시하였다. 정적균형과 동적균형을 측정하였으며 그룹내 훈련 전 · 후의 변화를 검증을 위하여 대응표본 t-검정을 실시하고, 그룹 간 훈련 전 · 후 변화의 차이를 검증하기 위하여 독립표본 t-검정을 실시하였다. 연구 결과, 그룹 내 훈련 전 · 후의 변화는 정적균형 및 동적 균형 모두 유의한 변화를 보였으나(p<.05), 그룹 간 훈련 전 · 후 변화량의 차이는 눈 감은 상태의 선자세 정적균형만 유의한 차이를 보이지 않았다(p>.05). 본 연구의 훈련이 뇌졸중 환자의 균형에 유의한 효과가 있음을 확인하였으며 특히, 훈련 시 좌석의 높이를 점진적으로 낮추어 제공하는 것이 뇌졸중 환자의 균형회복을 위한 새로운 치료방법으로 임상에서 활용되어 재활의 다양한 방향성을 제시되었음으로 사료된다. 그리고 연구 결과의 일반화를 위해 추후 연구는 많은 대상자에게 훈련의 적용이 필요하며 좌석 높이의 무작위 조성과 같은 다양한 훈련방법에 관한 연구들이 필요할 것이다. This study aimed to compare the effects of sit-to-stand training, or training to stand up from sitting positions at various seat heights, on the balance recovery among stroke patients. This study included 20 stroke patients who were randomly divided into two groups. Each group was trained for six weeks, three times a week from March to June 2019. Static balance and dynamic balance were measured, and the variations were analyzed using the paired t-test and the independent t-test. There were significant changes observed in both static and dynamic balance (p<.05) before and after training. However, no significant changes were seen in the static balance in the standing posture with eyes closed (p>.05). This study confirmed that there was a significant effect of training on the balance of stroke patients, especially when progressively lower seat heights were used during the training. This suggests new directions for treatment during rehabilitation for balance recovery of stroke patients. Further studies will need to apply this training to a larger number of subjects, and use various training methods such as randomization of seat height to enable the generalization of the results of this study and application in clinical practice.

김지선(Kim, Ji-Seon),서병도(Seo, Byoung-Do),신형수(Shin, Hyung-Soo),신희준(Shin, Hee-Joon),주정열(Ju, Joung-Youl) 한국산학기술학회 2015 한국산학기술학회논문지 Vol.16 No.12

본 연구의 목적은 발목관절의 발등굽힘 각도를 0°, 10°, 20°로 위치하게 한 후 각 각도에서 장딴지근의 깃각 변화에 미치는 영향을 비교하여 효율적인 장딴지근 신장 각도를 제시하는 것이다. 건강한 성인 남녀 25명을 그 대상으로 하여 발목 관절 발등굽힘 각도 0°, 10°, 20°에서 초음파 기기를 이용하여 내측 장딴지근의 깃각을 측정하였다. 각도별 장딴지근의 깃각 변화를 알아보기 위해 반복측정분산분석을 성별에 따른 각도별 차이를 알아보기 위해 독립 t 검정을 실시하였다. 연구의 결 과 발목관절의 발등굽힘 각도가 증가함에 따라 장딴지근의 깃각은 유의하게 감소하였으며, 각 각도별 사이 교호작용이 유의 한 것으로 나타났다(p<.01). 각 각도별 남녀 차이 비교 결과 남성의 깃각이 더 큰 값을 보였으나 유의한 차이는 없었으며 (p.>.05), 성별에 따른 발등굽힘 각도 증가에 따른 장딴지근의 깃각은 유의한 차이를 보였다(p<.01). 이러한 결과는 장딴지근 신장을 위한 발등굽힘 시 관절운동범위의 마지막 범위에서 시행하는 것이 장딴지근의 신장에 작은 각도로 시행하는 것보다 긍정적인 효과를 가져올 수 있다는 것을 의미한다. 향후 장딴지근 신장에 영향을 미치는 신장 각도, 적용 시간 등 다양한 요소들에 대한 연구가 지속되어야 할 것이다. This study aimed to investigate the influence of the ankle dorsiflexion angle (0°, 10°, and 20°) on the effectiveness of gastrocnemius stretching angle. The subjects of this study were 25 young man and female women. In all participants, the pennation angle of the medial head of the gastrocnemius was evaluated using ultrasonography at an ankle dorsiflexion angle of 0°, 10°, or 20°. Repeated measures analysis of variance was uesd to test for differences between ankle dorsiflexion angles. The independent t-test was performed to determine the significance of sex differences. The results of this study showed that the gastrocnemius pennation angle decreased as the ankle dorsiflexion angle increased, with significant interaction between each angle of ankle dorsiflexion angle (p<0.01). Sex comparison showed that the pennation angle was greater in man than in women, but the difference was not significant (p>0.05). According to the sex the gastrocnemius pennation angle is decreased as the ankle dorsiflexion angle increased (p<0.01). These results suggest that the end range of dorsiflexion is more beneficial for gastrocnemius stretching than a small range. Further studies are needed to investigate the influence of other factors, such as stretching angle and application time, on gastrocnemius stretching.

윤영대(Young Dae Yun),서병도(Byoung Do Seo),이상빈(Sang Bin Lee) 대한물리치료과학회 2008 대한물리치료과학회지 Vol.15 No.2

Background: The purpose of this study is to examine the effect of resistance exercise on static and dynamic proprioception by applying elastic bands to the knee flexor, which can be performed earlier than proprioception, a weight bearing pattern. Proprioceptive training may be applied to the early period of recuperation training along with resistance exercise to prevent damage to the knees and the joints in the lower body, as well as the reoccurrence of injury, which is expected to improve the effect of static and dynamic proprioceptive training. Methods: The subjects of this study were 32 men and women in their 20s who volunteered to participate in the experiment which was carried out over the course of 6 weeks from March 14 to April 24 at K Hospital located in Yongin City. They were tested in two groups: the elastic band resistance exercise group (RE: Resistance Excercise Group, n=17) and the joint motion range exercise group(ROM: Range of Motion Group, n=15). In this experiment, static and dynamic proprioceptive tests were given to both groups before and after the test. In this study, SPSS Win ver.12.0 was utilized to perform a T-test on the independent samples in order to validate the identical features of subjects in the RE and ROM Group and substantiate the significance as to the difference between both groups before and after the test. Also, a paired T-test was conducted to compare the static and dynamic proprioception of both groups before and after the test. The statistical significance levels were α =.05. Results: 1.The static proprioception in both groups, RE and ROM, increased in a statistically significant way after the test(p<.05). 2.The static propriocetion of the RE group increased in a statistically significant wa after the test(p<.05). However, the increase of the static proprioception in the ROM group was not statistically significant. 3.Static and dynamic proprioception of the RE group increased significantly more than that of the ROM group after the test(p<.05). Conclusion: The resistance exercise using elastic bands improved the static and dynamic proprioception more than the joint motion range exercise did, reducing the risk of injury by enhancing the location sense of the joints and the sense of motion and shortening the period of recovery from injury. The outcome of the experiment may provide basic data for developing an effective way to reduce the risk of injury among ordinary people and athletes.

Objectives: The purpose of this study was to investigate the effects of Socheongryong-tang, a traditional herbal medicine, on gastrointestinal (GI) motility disorders (inflammatory and diabetic models) in mice. Methods: The in vivo effects of Socheongryong-tang on GI motility were investigated by calculating percent intestinal transit rates (ITR) and gastric emptying (GE) values using Evans Blue and phenol red, respectively, in normal mice and in mice with experimentally induced GI motility dysfunction (GMD). GMD models were induced by acetic acid and streptozotocin. Results: In normal ICR mice, ITR and GE values were significantly and dose-dependently increased by the intragastric administration of Socheongryong-tang (0.0025∼0.25 g/kg). The ITR values (%) of GMD mice were significantly lower than those of normal mice, and these reductions were significantly and dose-dependently inhibited by Socheongryong-tang. Conclusions: These results suggest that Socheongryong-tang is a good candidate for the development of a prokinetic agent that may prevent or alleviate GMD.
