Purpose: This study was conducted to investigate the effects of skater exercise on cardiopulmonary fitness and balance function in patients with mild chronic stroke. Methods: A total of ten chronic stroke patients with mild neurologic deficits were recruited. The participants were divided into two groups, a skater exercise (n=5) and a control group (n=5). Skater exercise was performed by physical therapists in the experimental group, whereas patients in the control group conducted self-exercise. One session of the intervention was carried out for 30 minutes, three times per week for eight weeks. Cardiopulmonary function, falling index, and Euro-Quality of Life-5 Dimension (EQ-5D) were measured before and after the intervention. Results: No side effects were reported during and after skater exercise intervention. The peak aerobic capacity, falling index, and EQ-5D improved significantly in the experimental group compared with the control group after eight weeks of skater exercise (p=0.002, p=0.010, and p=0.006). Significant relationships were identified between the change in EQ-5D and peak aerobic capacity (R2=0.75, p=0.002)/falling index (R2=0.65, p=0.002). Conclusion: Skater exercise was an effective physical therapy to improve cardiopulmonary fitness and balance function in patients with mild chronic stroke.

PURPOSE: This study examined the foot pressure distribution using the sprinter and skater patterns of coordinative locomotor training. METHODS: Thirty healthy adults, comprising 11 men and 19 women, participated in the study. All the participants performed patterns in sprinter pattern conditions 1-3 and skater pattern conditions 1-3, and were measured using a pedoscan to determine the applied foot pressure distribution. RESULTS: The participants significantly differed in the big toe during the sprinter pattern. As a result of the post hoc test, opposite and opposite sprinters showed a significant difference from the same sprinters (same sprinter; 21.33 ± 5.92, opposite sprinter; 23.54 ± 5.41, and reopposite sprinter; 24.14 ± 6.46). There was a significant difference in the lateral side during the skater pattern. As a result of the post hoc test, reopposite and same skaters showed a significant difference from opposite skaters (same skater; 49.88 ± 5.75, opposite skater; 48.78 ± 5.64, and reopposite skater; 51.15 ± 5.37). CONCLUSION: The foot pressure was distributed toward the hallux and fifth toe according to the sprinter and skater patterns of coordinative locomotor training.

Purpose : To identify importance of coordinative locomotor training, we reviewed the coordinative locomotor training using sprinter & skater with respect to motor control theory. Methods : We reviewed literatures related with sprinter & skater and coordination.. Results : The coordinative locomotor training is useful tool to improve interlimb coordination. A problem of interlimb coordination ability is to minimize the degree of freedoms during walking and to solve with context-condition variability and how to make a interlimb coordinative structures. A way of solving method is coordinative locomotor training using sprinter & skater in PNF. The coordinative locomotor training set to fit the gait steps can be applied with gait tasks and can be extended by applying the irradiation of the PNF. Conclusion : The coordinative locomotor training using sprinter & skater in PNF is a useful way method to improve interlimb coordination during walking.

Purpose : The purpose of this study was to investigate the effect of the sprinter and skater combined patterns on muscle contraction onset time and muscle activation of body stabilizing muscles. Method : Our study included young and healthy men in their 20s. The participants used the sprinter and skater combined patterns of the proprioceptive neuromuscular facilitation (PNF) methods to measure muscle activation and muscle contraction onset time of the trunk muscles. To measure muscle contraction onset time and muscle activation, electrodes were attached to the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spinalis (ES) regions. Significant differences were identified using a paired t-test and a one-way analysis of variance (ANOVA) analysis. Result : In the sprinter combined pattern, the muscle with the fastest onset time of contraction was the RES, and that with the slowest was the RRA (p<.001). In the skater combined pattern, the muscle with the fastest onset time of contraction was the LES, and that with the slowest was the LRA (p<.001). In the sprinter combined pattern, the REO and LIO presented medium muscle contraction onset times (p<.001). In the skater combined pattern, the LEO and RIO presented medium muscle contraction onset times (p<.001). Conclusions: Based on these results, these patterns could be used as exercise methods for the elderly with delayed proactive response speeds of the body stabilization methods due to imbalances in body stabilizing muscles or limbs movement.

Purpose. This study was to investigate the change of dynamic balance and flexibility for normal group, using skater and sprinter exercise program of PNF pattern. Method. In this study it was participated twenty-one subjects. Experimental group worked skater and sprinter pattern exercise with Thera-band or without Thera-band each 40 times. Evaluation of dynamic balance and flexibility(using the Functional Reach Test and Fingertrip To Floor Test) were carried out before and after the exercise. Result. In dynamic balance it was observed to significant change except first measure and flexibility was observed to all measures significantly(p<.05). Conclusion. Skater and Sprinter pattern exercise is effective to improve for dynamic balance and flexibility. However, the experimental group is small sample size of normal adult. therefore, It should be carefully considered in generalizing the results to disabled person.

Purpose: The aim of this study was to assess the effects of proprioceptive neuromuscular facilitation (PNF) pattern exercise using sprinter and skater on balance and gait in the stroke patients. Methods: Twenty-two subjects were randomly assigned to the experimental group (n=11) and the control group (n=11). The experimental group performed PNF pattern exercise using sprinter and skater for 15 minutes with conventional physical therapy for 35 minutes (matt and gait training for 15 minutes + FES stimulation for 20 minutes), while the control group performed only conventional physical therapy for 50 minutes (matt and gait training for 30 minutes + FES stimulation for 20 minutes). Both groups performed therapeutic interventions for five days per week, for a period of four weeks. Functional Reach Test (FRT) and Berg Balance Scale (BBS) were used for assessment of balance, and Timed-Up and Go test (TUG) was used for testing of gait. Results: The experimental group showed significant improvements in the FRT and the BBS, while the control group did not show significant changes in two measurements. The experimental group also showed significant improvements, however, the control group did not show significant changes in the TUG. In post-values of three measurements, significant differences were observed between the two groups (p<0.05). Conclusion: This study demonstrated that PNF pattern exercise using sprinter and skater may be used to improve balance and gait function in stroke patients. Thus, we suggested that PNF pattern exercise using sprinter and skater would be a therapeutic intervention in stroke rehabilitation.

부동산 가격을 추정하기 위한 헤도닉 모형(hedonic model)의 적용에서 가장 중요한 사안은 모형의 정확한 구성과 하부시장의 구획이라 할 수 있다. 모형의 구성에 대해서는 비교적 활발한 개선 노력이 있었으나 하부시장 구획은 상대적으로 큰 관심을 받지 못하였다. 그러나 부동산 가격형성 과정의 공간적 범위 파악이 선행되지 않으면 헤도닉 모형의 적용 결과는 그 정확성이 저하될 수밖에 없다. 본 연구는 헤도닉 모형의 성능 개선에 초점을 두고, 서울시 25개 자치구 중 상대적으로 이질적인 부동산 집단으로 구성된 강남구와 비교적 균일한 부동산 집단으로 이루어진 중랑구를 사례지역으로 하여 하부시장 구획을 시도하였다. 먼저 하부시장 구획을 위한 투입변수로 혼합 GWR(Mixed GWR) 모형에서 산출된 가변 회귀계수(variable coefficients)를 사용하였다. 헤도닉 모형의 회귀계수는 부동산을 구성하는 속성항목(attributes)의 잠재가격(shadow price)으로 해석할 수 있기 때문이다. 다음으로 공간적으로 연접된 하부시장을 구획하기 위해 최소신장트리(minimum spanning tree)에 기반한 SKATER 앨고리듬을 사례지역에 적용하였다. 마지막으로 다수준 모형(multi-level model)을 적용하여 구획된 하부시장 결과의 적정성을 검토하였다. 검토 결과, 중랑구는 하부시장이 존재하지 않음을, 강남구는 간선도로를 중심으로 한 5개의 하부시장으로 구분하는 것이 합리적임을 확인하였다. 간선도로와 같은 도시의 인프라는 하부시장 구획에 있어 지금까지 큰 주목을 받지 못한 변수였으나 본 연구를 통해 그 중요성이 실증적으로 확인되었다.
