Purpose : The purpose of this study was conducted to find out observation at gait analysis of the stroke patient with proprioceptive neuromuscular facilitation(PNF) concept. Methods : This is a literature study with books, seminar note and international PNF course book. Results : Stroke patient gait was poor initial contact by weakness of tibialis anterior or weakness of contralateral plantar flexor, poor loading response by loss of deep sensation, poor mid stance by loss of deep sensation, weakness of tibialis anterior and weakness of plantar flexors eccentric control, poor terminal stance, pre-swing, initial swing by loss of deep sensation and stiffness fo deep toe flexors. Conclusion : Stroke patient gait determine on loss of mobility, pain, fear, trunk muscle weakness, loss of coordination, loss of deep sensation, neglect and apraxia. Therefore observational gait analysis of the stroke patient focus on gait cycle and take out hypotheses from the gait cycle. These hypotheses have to define accept or not by parameters. Treatment plan made with the hypotheses.

PURPOSE: This study aimed to determine the effects of task-oriented treadmill training on the gait and balance ability and functional activity in 20 patients with subacute stroke. METHODS: The study subjects were twenty stroke patients, ten randomly placed in the experimental group and ten in the control group. Both the experimental and control groups received 30 minutes of traditional physical therapy and an additional 15 minutes of functional electrical stimulation therapy. The experimental group was given task-oriented treadmill training, while the control group received general treadmill training. Each session lasted for 25 minutes, three times a week, over four weeks, totaling 12 sessions. RESULTS: Both groups showed statistically significant differences in the 10-metre walk test (10MWT), timed up and go test (TUG), Fugl-Meyer Assessment (FMA), and Modified Barthel index (MBI). However, statistically significant differences in the Functional Ambulation Categories (FAC) and Berg Balance Scale (BBS) were seen only in the experimental group. There were statistically significant differences in the between-group differences value comparisons in the 10MWT, BBS, TUG, FMA, and MBI. CONCLUSION: Task-oriented treadmill training positively impacts gait, balance, and daily function in subacute stroke patients. This study highlights the benefits of training on unstable surfaces and offers valuable insights for stroke rehabilitation and gait training.

Background & Purpose : The purpose of this study is to evaluate the impairment of SVMC(selective voluntary motor control) of the lower extremity by assessing each joints of lower limb and to analyze the motional relationship between each joints of lower limb using SCALE(Selective Control Assessment of the Lower Extremity) during the swing phase of gait cycle in children with spastic diplegia. Method : 11 children with spastic diplegia CP who could walk independently and 10 normal developing children were participated. SCALE(Selective Control Assessment of the Lower Extremity) assessments were conducted for 11 children with CP. Gait analysis were accomplished in all participants. Qualisys motion analysis was used as a statistical tool to assess the motional relationship between hip joint, knee joint and ankle joint in each limb. We used descriptive statistics, cross-tabulation, independent t-test, linear regression to analysis motional relationship between each joints of lower limb using by SPSS ver.17.0. Result : Firstly, there were significant differences in SCALE scores between the cerebal palsy group and the control group in knee joint(p<0.05), but no significant difference in hip and ankle joints during the swing phase of gait cycle. Secondly, the difference of SCALE scores showed no statistical motional difference in knee and ankle joints during the swing phase, and showed significant motional difference in hip joints during the swing phase(p<0.05). Thirdly, there was a liner relationship between the motion of hip and ankle joints during the swing phase. Conclusion : The nature of SVMC(selective voluntary motor control) in each joints of the lower limb may reflect the ability of gait, thus SCALE may be used for assessing and for treating the cerebal palsy patients who are able to walk independently. Also we knew that the impairment of SVMC(selective voluntary motor control) increases from the proximal to the distal joints.

PURPOSE: The present study examines how feedback respiratory exercise affects gait performance of stroke patients. METHODS: Forty stroke patients were randomly divided into an experiment group and a control group. For the former group, patients went through a half-hour of training therapy and a half-hour of feedback respiratory device exercise. For the latter group, patients went through 30 minutes of training therapy and a half-hour of motomed exercise. All participants had five training sessions each week for four weeks. For measurement, a GAITRite system was used to examine spatial parameters, and functional ambulation performance before and after the training. RESULT: In terms of spatial parameters, double support ratio, stance phase increased significantly in the experiment group after the walking exercise(p<.05). FAP rose more significantly in the experiment group than in the control group(p<.05). In comparison of two exercise groups, double support ratio, Stance phase, gait velocity, FAP was significant difference(p<.05). CONCLUSION: The experiment results showed that feedback respiratory exercise is effective in enhancing gait performance.

This paper proposes a method that minimizes the consumed energy by searching the optimal locations of the mass centers of links composing of a biped robot using Real-Coded Genetic Algorithm. Generally, in order to utilize optimization algorithms, the system model and design variables must be defined. Firstly, the proposed model is a 6-DOF biped robot composed of seven links, since many of the essential characteristics of the human walking motion can be captured with a seven-link planar biped walking in the saggital plane. Next, Fourth order polynomials are used for basis functions to approximate the walking gait. The coefficients of the fourth order polynomials are defined as design variables. In order to use the method generating the optimal gait trajectory by searching the locations of mass centers of links, three variables are added to the total number of design variables. Real-Coded GA is used for optimization algorithm by reason of many advantages. Simulations and the comparison of three methods to generate gait trajectories including the GCIPM were performed. They show that the proposed method can decrease the consumed energy remarkably and be applied during the design phase of a robot actually.

The purpose of this study was to examine the effects of dual-task training (cognitive and exercise tasks) on the balance and gait performance of chronic stroke patients. Eighteen subjects with chronic stroke were divided equally into two groups, an experimental group and a control group. Subjects in both groups participated in an exercise program, performing the same tasks, for 45 minutes per day, three times per week for four weeks. The experimental group also performed additional cognitive task. The experimental group showed a more significant improvement than the control group on the Berg Balance Scale, the Timed Up and Go Test, the Korean Activities-Specific Balance Confidence Scale, and the Functional Gait Assessment (p<.05). The cognitive task error rates in the final week were significantly less than in the first week in the experimental group (p<.01). These results suggest that dual-task training for chronic stroke patients is effective in improving balance, gait, and cognitive abilities.

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.

Purpose: This study examined the characteristics of gait in patients with chronic low back pain. Methods: The subjects were out-patients suffering from chronic low back pain at the department of physical therapy, B hospital in Seoul. Gait analysis was performed by dividing the subjects into two groups. The study and control group comprised 15 chronic low back pain patients and 14 healthy people, respectively. Gait analysis was performed using a VICON 512 Motion Analysis System to obtain the spatio-temporal and kinematic parameters. Results: First, there was a significant difference in the spatio-temporal parameters between the two groups (p<0.05). Second, the study group showed significant differences in the kinematic parameters during the stance phase (p<0.05). Third, there were significant differences in kinematic parameters in the study group during the swing phase (p<0.05). Conclusion: The gait pattern of patients with chronic low back pain is characterized by more rigid patterns. Compared to the control group, there was a decrease in the spatio-temporal parameters and kinematic parameters in patients with chronic low back pain. These findings are expected to play a role as basic data and to form a rehabilitation program for low back pain patients.
