This paper is concerned with smooth trajectory generation of biped robot which has inverted pendulum type balancing weight. Genetic algorithm is used to generate the trajectory of the leg and balancing weight. Balancing trajectory can be determined by solving the second order differential equation under the condition that the reference ZMP (Zero moment point) is settled. Reference ZMP effect on gait pattern absolutely but the problem is how to determine the reference ZMP. Genetic algorithm can find optimal solution under the high order nonlinear situation. Optimal trajectory is generated when use genetic algorithm which has some genes and a fitness function. In this paper, minimization of balancing joints motion is used for the fitness function and set the weight factor of the two balancing joints at the fitness function. Inverted pendulum type balancing weight is very similar with human and this model can be used fur humanoid robot. Simulation results show ZMP trajectory and the walking experiment made on the real biped robot IWR-IV.

Purpose: The cerebellum is a region of brain structure that plays an important role in calibrating two different information of neural signal from descending motor commands and from ascending sensory inputs. Damage of the cerebellum shows a variety of classic motor symptoms such as postural and locomotor dysfunctions. Therefore, we tried to investigate motor function and skill in stroke patients with cerebellar lesions in sub-acute stage, and compare with these functions of patients with non-cerebellar lesions. Methods: Total twelve stroke patients with cerebellar lesion and 130 stroke patients with non-cerebellar lesions were retrospectively recruited in this study. For evaluation of motor strength, Motricity index (MI) for upper and lower limbs was tested. For measurement of motor skill function, the modified Brunnstrom classification (MBC), Manual function test (MFT), functional ambulatory category (FAC), and Barthel index were adopted. Results: In comparison of motor strength and motor skill function between two groups, statistical differences between the two groups were significantly observed only in upper MI and FAC. Although no significant differences were found in other variables, stroke patients with cerebellar lesion had higher scores in lower and total MI, MBC, and MFT, whereas they had lower scores in FAC and Barthel index. Conclusion: Our results showed that stroke patients with cerebellar lesion had greater impact on movement functions related to hand motor and walking ability in activities of daily life, compared with patients with non-cerebellar lesion, in spite of similar degree of motor function and skill between the two different lesioned-groups.

Objective: The purpose of this study was to evaluate the relationship between quality of life (QoL) of the caregiver and disease severity with motor function in children with cerebral palsy (CP). Design: Cross-sectional study. Methods: Research data were collected in the Rehabilitation Clinic of Daegu University. The Gross Motor Function Measure (GMFM-88) and the functional independence measure (FIM) were used for assessment by three occupational therapists, and the 36-item short form health survey (SF-36) were applied to the caregivers. One hundred six caregivers of under 18 years who were diagnosed with CP completed a survey and interview. The caregivers' QoL was evaluated using Medical Outcomes Study SF-36. The children's motor function was scored using GMFM-88 in five dimensions: lying and rolling; sitting; crawling and kneeling; standing and walking, running and jumping and CP's FIM scores. Results: Out of the 8 domains of the Medical Outcomes Study SF-36, the "physical functioning", "physical role functioning", "mental health", and "bodily pain" domains were significantly correlated to "total" percentage scores of the GMFM-88 (p<0.05). In addition, the "mental health" domain was correlated to each subdomain of the GMFM-88, which includes, "lying and rolling", and "crawling and kneeling". Similarly, of Medical Outcomes Study SF-36, "physical functioning", "bodily pain", and "mental health" domains were significantly correlated with "transfer" and "locomotion" of FIM scores (p<0.05). Conclusions: This study showed that the QoL of the caregivers were well correlated with the motor function of children with CP. It is also important to support not only physical health but also psychological health of caregivers of children with CP, especially those with severe motor function.

Purpose : This study aims to present a rehabilitation exercise and physical education program (REPEP) for local community stroke patients by examining an exercise program provided from traditional physical therapeutic perspectives. Methods : The subjects were 40 stroke patients residing in a local community and managed by a public health center (the group-exercise group: 20, the individual-exercise group: 20). In the case of the group-exercise group (GEG), the subjects were divided into small groups composed of five members each to participate in the program. The individual-exercise group (IEG) took part in the program individually. The subjects received a REPEP that included a warm-up exercise, an elastic band exercise, a leg exercise, a balance and gait exercise, an arm and trunk exercise, and a cool-down exercise twice per week for 20 weeks. They had their gait function, balance index, and muscle strength in the bilateral knee joints tested before and after the experiment. Results : Compared to before the experiment, both groups' gait function, balance index, and muscle strength in the knee joints increased after the experiment. After the experiment, the GEG experienced more improvement in their gait function, balance index, and muscle strength in the bilateral knee joints, excluding their gait velocity and $300^{\circ}/sec$ flexion and extension, than the IEG (p<.05). Conclusion : An exercise program provided from the traditional physical therapeutic perspectives may be applied to stroke patients as their REPEP. In addition, a REPEP was more effective in improving their gait function, balance index, and muscle strength in the knee joints when the subjects formed a group and took part in the program than when they partook in it individually.

Background: The purpose of this study was to investigated the effects of threshold resistance inspiratory muscle training on respiratory function in chronic stroke patients. Design: Randomized Controlled Trial Methods: Eighteen patient with stroke were randomly assigned to the experimental group (n=9) and control group (n=9) all testing and training. The experimental group underwent threshold resistance inspiratory muscle training with resistance adjusted of maximal inspiratory pressure, 60 breathing a day and general physical therapy 30 minutes a day, 5 times a week for 4 weeks. The control group was taken general respiratory muscle training and general physical therapy for 4 weeks in the same way. Respiratory function, walking ability were evaluated before and after the intervention. Statistical significance of the results were evaluated by ANCOVA between control group and experimental group after intervention. Results: There was a significant increase in FVC and FEV1 in the experimental group in pulmonary function tests (p<0.05). There was a significant difference with the maximum inspiratory pressure and the maximum inspiratory flow rate between experimental and control group (p<0.05). There was no significant difference with the maximum inspiratory capacity between experimental and control group (p>0.05) but the maximum inspiratory capacity of experimental group some increased than that of control group. Conclusion: These finding gave some indications that the threshold resistance inspiratory training may benefit on pulmonary function in people with stroke, and it is feasible to be included in rehabilitation interventions with this population.
