RESUMEN
@#Objective To simulate and evaluate the upper and lower limbs posture on rehabilitation devices training with the Computer Aided Tri-Dimensional Interface Application (CATIA) man-machine analysis module. Methods The human body sizes were determined as the 95th percentile Chinese men. Based on the ergonomics analysis of CATIA, three-dimensional human body was constructed in the upper and lower limbs rehabilitation equipment. Virtual human relationship was established. The attitude of the upper and lower limbs in rehabilitation equipment was simulated and evaluated. Results The human limbs model moved in the normal range and the scores were more than 90 which meant comfortable. The forces of various parts of the body was under the stress limit, as well as the force moment. The arm tension was 3-5 points with the rapid upper limb assessment, which meant the rehabilitation equipment was acceptable. Conclusion Rehabilitation robot may be optimized through the model of the human upper extremity stretch domain analysis, body posture assessment, rapid upper limb assessment and biomechanical analysis under CATIA.
RESUMEN
O objetivo foi investigar as relações entre força muscular nos membros inferiores e nos superiores, prática de exercícios físicos e atividades de vida diária em mulheres idosas recrutadas na comunidade. Um mil quinhentas e trinta e oito idosas com idade média = 72,07 ± 5,46, renda familiar média = 3,59 ± 3,96 SM, sem déficit cognitivo sugestivo de demência. Foram submetidas a medidas de força de preensão manual e velocidade de marcha; a itens de autorrelato sobre prática regular de exercícios físicos; de desempenho de 13 atividades avançadas de vida diária (AAVD) de natureza social (ex: trabalhar, viajar e frequentar igreja) e de 3 atividades instrumentais de vida diária (AIVD) manejar dinheiro, fazer compras e usar transporte, 1.538 idosas com idade média = 72,07 ± 5,46, renda familiar média = 3,59 ± 3,96 SM, sem déficit cognitivo sugestivo de demência. Foram preditivos de pior desempenho em atividades de vida diária (AVD): baixa força muscular (OR = 2,48 para comprometimento da preensão e da marcha e 1,66 para comprometimento em qualquer dos critérios), baixa renda (OR = 2,46 e 2,45 para < 1 e para 1,1 a 3,0 SM) e sedentarismo (OR 2,08). A funcionalidade de mulheres idosas é afetada pelo envelhecimento fisiológico e por condições contextuais e de estilo de vida.
The scope of this study was to investigate relationships between muscle strength of the upper and lower limbs, physical exercise, and functionality to perform complex activities of day-to-day life in elderly women recruited from the community. 1538 elderly women with mean age = 72.07 ± 5.46 and average household income = 3.59 ±3.96 MW, without cognitive deficit suggestive of dementia, were submitted to tests of grip strength and walking speed. They were asked to self-report on regular practice of physical exercise and performance of 13 social AADLs (e.g. working, travelling and church attendance) and 3 IADLs (handling money, doing the shopping and using public transport). The worst performance key factors were low grip strength and low gait speed in ADL (OR = 2.48 if both; OR = 1.66 if either were present), as well as low income (OR = 2.46 low income < 1 MW and = 2.45 to 1.1 and 3.0 MW) and sedentary life style (OR = 2.08). The functionality of elderly women is influenced by physiological aging, but also by contextual conditions and life style.
