BACKGROUND:Abnormal gaits are very common in children with cerebral palsy, and how to improve the gait is the focus of rehabilitation therapy. OBJECTIVE:To analyze the biomechanical parameters of gaits in cerebral palsy children and to observe the effects of brace control on the exercise capacity of dyskinetic cerebral palsy children. METHODS:In this paper, we compared the biomechanical parameters of children with cerebral palsy and normal children in the initial process of walking and during walking. Biomechanical parameters in the initial process of walking include spatial and temporal parameters, kinematic and kinetic parameters of the range of motion of the knee and ankle. Biomechanical parameters during walking include spatial and temporal parameters. With the aid of hand brace, dyskinetic cerebral palsy received postural control, gait training, and sling exercise therapy for 3 months. The Gross Motor Function Measure (GMFM-88) assessment and video control were conducted for evaluation of therapeutic efficiency. RESULTS AND CONCLUSION:Biomechanical parameters in the initial process of walking showed significant differences between children with cerebral palsy and normal children except for the peak of ground reaction force at frontal axis with the right foot to start walking. Biomechanical parameters during walking showed that the stance phase and bipedal stance phase were prolonged, while the step length and stride length were shortened in the children with cerebral palsy compared with the normal children. For cerebral palsy children with brace control, the GMFM-88 scores were significantly decreased after treatment, involuntary movements were reduced shown on the video, the neck and body were stable, and life skil s were improved. Children with epilepsy and cognitive impairment or who had imaging changes in the basal ganglia showed a little improvement, and children with dance-athetoid type and dystonia type had a better progress than those with athetoid spasm.

Objective To explore the resilience status and its influencing factors of rescue nurses in Wenchuan earthquake, so as to provide evidence for future psychological intervention and psychological rehabilitation. Methods Totally 736 nurses who took part in the rescue works of the great Wenchuan earthquake were selected as the research objects. They were surveyed by a self-designed general information questionnaire and the Connor-Davidson resilience scale (CD-RISC) in order to understand the psychological resilience factors of rescue nurses in Wenchuan earthquake. Results Total score of CD-RISC of 736 rescue nurses was (59.03±20.67) points, scores of tolerance, strength and optimism were (29.64±11.58), (20.55±6.70), (8.83±3.50) points, respectively. Univariate analysis showed that rescue nurses had different posttraumatic growth who had different gender, cultural level, household income monthly per capita, financial loss in the disaster, rescue place, physical health status, satisfaction with houses, satisfaction with leaders and colleagues, friends and relatives. Multiple linear regression analysis showed that household income monthly per capita, satisfaction with leaders and colleagues, title and physical health status could affect the total score of CD-RISC (adjust R2=0.157, F=12.163, P<0.01). Conclusions After 6 years of earthquake, the resilience of rescue nurses in disaster areas is at moderate level and needs to be improved. Household income monthly per capita, satisfaction with leaders and colleagues, title and physical health status are independent factors affecting rescue nurses' resilience. It is suggested to pay attention to such high-risk groups, and give them positive and effective psychological intervention to improve the resilience level of disaster relief nurses.
