Objective: The objective of this study is to investigate the effect of treadmill gait trainig on dynamic balance and gait functions in stroke patients. Design: Randomized, double-blind, controlled pilot study. Methods: Four subjects following first stroke participated in this study. They were divided randomly into the treadmill gait trainig group (TM group) (n=2) and the control group (n=2). Subjects in both groups received general training five times per week. Subjects in the TM group practiced an additional treadmill gait trainig program that consisted of 60 minutes, three times per week, during a period of four weeks. Timed up and go test (dynamic balance) and the GAITRite test (gait function) were evaluated before and after the intervention. Results: In dynamic balance (timed up and go test), the TM group (-14.235 sec) showed a greater decrease than the control group (-13.585 sec). In gait functions, the TM group showed a greater increase in gait speed (12.8 cm/s vs. 10.15 cm/s), step-length (5.825 cm vs. 3.735 cm), and stride-length (5.005 cm vs. 1.55 cm) than the control group. Conclusions: The treadmill gait trainig improved dynamic balance and gait functions. Further research is needed in order to confirm the generalization of these findings and to identify which stroke patients might benefit from treadmill gait trainig.

Manual tracking is an experimental paradigm that can be used to study information processing in continuous movements involving accurate, ongoing control of motor performance. The purpose of this study was to identify the effects of knee tracking training, using the paretic side, on gait in stroke patients. Nine patients with hemiplegia participated in the study. The timed 10 m gait speed test and tracking test were administrated. The tracking test was composed with ranges of $-20^{\circ}$ to $20^{\circ}$ and $0^{\circ}$ to $60^{\circ}$. The tracking training consisted of five times every week for 4 weeks. The data were analyzed by non-parametric paired sign test of Wilcoxon. The flexion/extension error of the tracking test was significantly reduced on the paretic side, while the nonparetic side was not statistically significant. The transfer of the skill to the functional activity was shown in the significant improvement at timed 10 m gait speed test. This study shows that individuals with chronic who have impaired knee movement can be trained to improve their knee control through intensive practice at a knee movement tracking task and that the skill learned from such training is transfered to a more functional gait speed.

Purpose: This study aimed to describe and identify the relationship between gait and contracted ratios of the transverse abdominal (TrA), internal oblique (IO), and external oblique (EO) muscles. Methods: This study was conducted on 50 elderly people. The contracted ratios of the lateral abdominal muscles (LAM) were measured using the abdominal drawing-in maneuver (ADIM) and ultrasonographic imaging. Gait was measured using the timed up and go test and the 10 m walk test. Results: The contracted ratios of the TrA and IO muscles significantly increased after ADIM. Those of the TrA muscles showed a significant correlation with gait in the limited community ambulatory group. The contracted ratios of the IO and EO muscles showed a significant correlation with gait in the community ambulatory group. Conclusion: Our findings suggest a specific training on the relationship between gait speed and the activation of the LAM in elderly people.

The purposes of this study were to describe and compare pint moments according to 6 types of gait methods during free speed. 15 volunteers(7 male, 8 female: mean age = 23.33 yrs.) participated and performed 6 types of gait methods. From the 3 types of pint moments of lower extremities(hip, knee, ankle and foot), the following results were made: 1. In left hip pint, the flexion-extension moment was not significantly different, but the adduction-abduction moment and rotation moment were showed different curves during stance phase. 2. In left knee pint, the flexion-extension moment was not significantly different, but the varus-valgus moment and rotation moment were showed different curves during stance phase. 3. In left ankle and foot the dorsiflexion-plantarflexion moment was not significantly different but the varus-valgus moment and rotation moment were showed different curves during stance phase. In conclusion, because weight loading gait with 10-20% of body weight were normal gait patterns, It was inferred that all weight loading gaits did not indicate noxious reactions of human body.

In this paper, we propose a gait type classification method based on pressure sensor which reflects various terrain and velocity variations. In order to obtain stable gait classification performance, we divide the whole gait data into several steps by detecting the swing phase, and normalize each step. Then, we extract robust features for both topographic variation and speed variation by using the Null-LDA(Null-Space Linear Discriminant Analysis) method. The experimental results show that the proposed method gives a good performance of gait type classification even though there is a change in the gait velocity and the terrain.

Purpose: This study reports the basic reference data of the specific gait parameters for Korean normal adults. Methods: The basic gait parameters were extracted from 73 Adults (35 men and 38 women), 18 to 33 years of age, using a Vicon MX motion analysis system. The segment kinetics, such as joint moment and power, was analyzed at the hip, knee and ankle. Results: The motion patterns are typically associated with a specific phase of the gait cycle. The temporal-spatial gait parameters of Korean normal adults, such as cadence, walking speed, stride length, single support and double support, were similar to the other western reference data. The kinetic parameters of Korean normal adults, such as joint moments of force, joint mechanical power generation or absorption and ground reaction forces, were also similar to other western reference datasets. Conclusion: This study demonstrates that objective gait analysis can be used to document the gait patterns of normal healthy adults. The techniques of 3-dimensional temporal-spatial gait parameters and kinematic parameters analysis can provide a detailed biomechanical description of a normal and pathological gait.

본 연구의 목적은 마비측 다리에 나선형 방향으로 테이핑을 적용하여 뇌졸중 환자의 보행능력에 미치는 즉각적인 효과를 알아보고자 하였다. 뇌졸중 환자 42명을 각각 실험군(나선형 테이핑군) 21명과 대조군(넙다리네갈래근 테이핑군)21명으로 나누어 테이핑을 부착하였다. 두 집단 모두 10m 보행 검사(10 meter walk test)와 동적 보행 지수(Dynamic Gait Index; DGI), 가속도계(Accelerometer)를 이용한 시 공간적 보행변수 중 보행율(cadence), 속도(speed), 마비측 보행주기(gait cycle duration), 마비측 디딤기(stance phase duration), 마비측 양발 지기기(double support duration)를 측정하였다. 연구 결과 중재 전과 중재 후 두 집단 모두 10m 보행과 DGI 그리고 보행율, 보행속도에서 유의한 증가를 보였고 마비측 디딤기, 마비측 보행주기, 마비측 양발지지기에서 증가 및 감소하였지만 유의한 차이가 없었다. 두 집단간 변화량 차이는 유의한 차이가 없었다. 테이핑을 통한 뇌졸중 환자의 보행능력 변화에서 두 방법 모두 보행능력에 증가함을 알 수 있었다. 하지만 나선형 테이핑은 테이핑 절단 횟수가 적고 비교적 쉽게 적용이 가능하므로 가정에서 적용 시 보다 쉽게 적용할 수 있는 방법일 것이다.

다리를 가진 로봇은 지형에 대한 높은 적응능력을 가졌다할지라도 바퀴의 차량과 비교했을 때 일반적으로 그 속도가 상당히 낮다. 다리를 가진 로봇으로 빨리 움직이는 속도를 얻기 위해서는 두발 로봇의 달림과 4족 로봇의 속보나 뛰는 것과 같이 동적으로 안정한 걸음걸이가 좋은 해결법이다. 그러나 동적으로 안정한 걸음걸이의 에너지 효율은 일반적으로 느린 걸음걸이와 같은 안정한 걸음걸이보다 낮다. 본 논문에서는 네발로 걷는 로봇의 에너지 효율에 관한 실험적 연구를 보여준다. 빠른 걸음걸이의 2가지 패턴의 에너지 소모에 대한 TITAN-VIII을 이용한 실험을 통해 연구하였다.

Purpose: The purpose of this study was to investigate the lumbar erector spinea and rectus abdominis activations, according to the different gait velocities in young healthy adults. Methods: We recruited 6 young male and 10 young female (mean age=21.43 years; range 19~23) in this study. We used a wireless surface electromyogram (Telemyo 2400T G2, Noraxon, USA) and a treadmill unit for the experiment. EMG activity from the lumbar erector spinea, and rectus abdominis of the dominant side was record with surface electrodes. On different day, all subjects gaited on 2.7 km/h, 4.5 km/h, and 6.3 km/h of speed in random order. They gaited at the same velocity, three times, on the treadmill unit. To reduce fatigue, sufficient rests were given between the measurements. Results: As the gait speed increased, lumbar erector spinea and rectus abdominis activations were significantly increased (p<0.05). Conclusion: In the current study, we found lumbar erector spinea and rectus abdominis activations were changed, according to the gait velocity. We suggested that rehabilitation intervention should be focused on the exercise velocity for the patients with problem of the trunk control.
