简要总结
This study developed a system for studying an individual's postural balance in an upright position on a force platform with controlled movement of 2-axis rotation (transverse and anteroposterior), by analyzing lower limb muscle activation and data from Pressure Center of displacement.
详细描述
The use of rotating force platforms has proven to be an important resource in the study of postural balance and motor control. Platforms composed of two force plates allow the analysis of the load relationship between the feet and the study of the coordination of the lower body segments in postural control. Center of pressure displacement data during perturbations generated by platform rotation allow the study of dynamic postural balance. However, devices that meet these characteristics are not common and have limitations on amplitude or speed of rotation. Thus, a force platform composed of two plates was developed, capable of collecting data for the calculation of the parameters of the center of pressure, differentiating each foot, with a computerized system to control amplitude and speed of rotation in the mid-lateral and anteroposterior axes. A new version of embedded and supervisory systems that control the device, collect and process the created data has also been developed. For platform functionality tests, volunteers were divided into three groups of 15 individuals: Group 1 (G1): women aged 18 to 40 years; Group 2 (G2): women aged 40 to 60 years; Group 3 (G3): women over 60 years old.
