The purpose of study was to investigate the kinematic variables of Kenmotsu motion in Parallel bars. To this study, by 3 dimensional kinematical analysis of 4 male national gymnasts participants in the 28th Athens Olympic Game in 2004, kinematic data collected using video camera. Coordinate data were smoothed by using a fourth-order Butterworth low pass digital filter with cutoff frequency of 6Hz. The conclusions were as follows. 1. In P2, because the constrained swing movement made the movement of a rising back difficult7, the movements of Reg. were performed at low position after Air phase. 2. In E5 event, for the shake of a stable handstand and applied techniques like a Belle(E-value), a Belle Piked(super E-value), a vertical velocity in E2, a horizontal velocity in E3 and a vertical velocity in E4 were necessary for high velocities. 3. In E4 event, it was appeared that for a flexible body's movement of a vertical up-flight, the large angle of the shoulder joint and the flexion & extension of the hip joint were necessary in Air phase and a long flight time and vertical displacement made Reg. movements stable at the high position.

Purpose: The purpose of this study was to verify the effect of applying clam exercise on improving trunk control and balance ability in stroke patients. Based on this, we tried to provide clinical information. Methods: In this study, 18 patients with chronic stroke were recruited from a rehabilitation hospital. The patients were divided into two groups: a clam exercise group (9 patients) and a control group (9 patients). After 30 minutes of neuro-development therapy, they performed clam exercise or bridge exercise for 3 weeks, 5 times a week for 30 minutes. A trunk impairment scale (TIS) and a postural assessment scale for stroke patients-trunk control (PASS-TC) were performed to evaluate the subjects' ability to control trunk before and after intervention. Balance ability was measured by Balancia before and after intervention. Results: After the training periods, area 95% COP and weight distribution of the affected side were significantly different from the clam exercise group compared to the control group (p<0.05). Conclusion: Based on the results of this study, in can be seen that the clam exercise is effective in improving the balance ability compared to the bridge exercise. Maintaining the standing posture requires muscle strength of the hip abduction and extension, which is the result of the clam exercise selectively strengthening these muscles. Therefore, if you want to provide intervention to improve the balance of stroke patients, it is recommended to perform a clam exercise.

A normal range of motion is essential for performing activities of daily living. The capsular pattern is the proportional motion restriction in range of motion during passive exercises due to tightness of the joint capsule. Although the capsular pattern is widely referred to in clinical practice, there is no scientific evidence to support the concept. In this review, the appropriateness of the capsular pattern for evaluation of joint pathology was assessed. In the Textbook of Orthopaedic Medicine written by Cyriax, the capsular pattern did not specify how much reduction in angular motion is considered motion restriction. As the definition proposed initially was unclear, different methods have been used in previous studies investigating capsular pattern. In addition, the capsular pattern described all the major joints of the human body, but only the hip joint, knee joint, and shoulder joint were studied in experimental studies. Sensitivity and specificity were reported in one study and were meaningful in specific pathologies (loss of extension to loss of flexion). There was no consensus on the reliability and validity. In summary, the capsular pattern suggested by Cyriax or Kaltenborn is not supported or applies only to certain conditions. Various components around a joint complement each other and provide stability to the joint. It is recommended that the therapist perform multiple assessments rather than rely on a single assessment when evaluating joints.

This paper recognizes the motion intention of the wearer using a muscle stiffness sensor and proposes a control system for a wearable robot based on this. The proposed system recognizes the onset time of the motion using sensor data, determines the assistance mode, and provides assistive torque to the hip flexion/extension motion of the wearer through the generated reference trajectory according to the determined mode. The onset time of motion was detected using the CUSUM algorithm from the muscle stiffness sensor, and by comparing the detection results of the onset time with the EMG sensor and IMU, it verified its applicability as an input device for recognizing the intention of the wearer before motion. In addition, the stability of the proposed method was confirmed by comparing the results detected according to the walking speed of two subjects (1 male and 1 female). Based on these results, the assistance mode (gait assistance mode and muscle strengthening mode) was determined based on the detection results of onset time, and a reference trajectory was generated through cubic spline interpolation according to the determined assistance mode. And, the practicality of the proposed system was also confirmed by applying it to an actual wearable robot.

Purpose: This study investigated the effect of proprioceptive neuromuscular facilitation (PNF) on gait speed in a stroke patient with genu recurvatum. Methods: The subject was a 52-year-old female diagnosed with stroke. Information on health was collected through client Interview based on the International Classification of Functioning, Disability and Health (ICF). The ICF was used to identify connections between functional problems, and for diagnosis, and functional problems were described using ICF terms. For prognostic purposes, comprehensive goals for functional activity and participation level are presented as long- and short-term goals. Intervention was performed using an exercise program composed of techniques and principles based on PNF concepts for 50 minutes a day, 3 times a week, for 6 weeks. Gait speed and lower limb strength before to after intervention differences were used as study outcomes. Results: Clinical advantages were observed in body function (3.6kg increase in knee extension strength, 1.4kg increase in knee flexion strength, 0.9kg increase in hip abduction). Gait speed, which was the patient's primary limitation, was improved by 0.2m/sec. Conclusion: Based on the results of this study, application of the PNF concept would appear to improve gait speed and genu recurvatum in stroke patients.

Objectives : In order to investigate the relation of body composition analysis and isokinetic trunk muscle strength for the screening test of low back pain. Methods : This study was carried out with the data from comprehensive medical testing. 75 subject aged 20-59 performed the segmental bioelectrical impedance analysis, isokinetic trunk muscle strength test and questionnaire. Then we analyzed the relationship of data. Results : Low back pain(LBP) prevalence in high obesity index(Body mass index(BMI), Percentage of Body Fat(PBF), Waist Hip Ratio(WHR)) group was higher than LBP prevalence in normal obesity index group(p<0.001). In LBP group, Extension Peak Torque(Ext.PT), Extension Peak Torque per Body Weight(Ext.PT/BW) were significantly lower than Non-LBP group(p<0.001). And 90% of LBP group indicated abnormal Extension-Flexion Ratio(E/F ratio)(1.0 < Normal E/F ratio <1.6). When it comes to analyze relation between obesity index and muscle strength, Ext.PT/BW was significantly decreased according to PBF, WHR score. And correlation coefficient in Flex.PT, Flex.PT/BW, Ext.PT, Ext.PT/BW and PBF showed decreasing function. Conclusions : Results from this investigation showed positive correlation between obesity and LBP prevalence. Decreased muscle strength and inbalanced E/F ratio were shown in LBP. Trunk muscle strength was changed according to body mass composition parameters. This results are expected to contribute to prevent and diagnose LBP by application the clinical index of body composition analysis.

무릎 과다 폄을 가진 대상자에게 비대칭적 선 자세와 같은 외부적 요소가 추가되게 되면 무릎 관절에 가해지는 체중 지지가 더 증가하게 되며, 무릎 뒤쪽 구조들의 과신장이 유발된다. 이는 무릎 과다 폄 변형을 증가시킬 뿐만 아니라, 앞 십자인대와 같은 무릎 주변 연부조직의 변형 및 손상을 유발하는 요인이 될 수 있다. 따라서, 비대칭적 선 자세가 무릎 관절의 위치와 하지 근육의 활성도에 어떠한 영향을 미치는지 알아보는 것이 이 연구의 목적이다. 33명의 자발적 참여대상자들이 연구에 참여하였으며 총 60개의 다리에 대하여 무릎 과다 폄군, 정상군으로 나누어 하지근육의 근 활성도 및 무릎 폄 각도를 측정하였다. 비대칭적 선 자세 시, 무릎 관절 폄 각도와 장딴지근의 근 활성도 값은 정상군과 무릎 과다 폄 군 사이의 통계학적 유의한 차이가 나타났다. 결과를 토대로 비대칭적인 선 자세가 무릎의 과다 폄을 증가시키는 요인이 됨을 확인하였다. 따라서, 무릎 정렬에 이상을 가진 대상자들에게는 정상적인 정렬 회복과 함께 대칭적인 선 자세를 유지할 수 있도록 하는 치료적 중재 수립에 도움을 줄 것이며, 추후 엉덩관절과 발목관절의 영향을 포함한 조사연구가 필요하겠다.
