Resumen


This work describes an electronic  system  implemented with  two  force plates,  24  load  cells with  strain  gages, signal conditioning circuit, interfacing circuit and data acquisition system, designed for measuring plantar force distribution in patients. The sistem presented  linear response,  low hysteresis, with  determination  coefficient  of  0.9997,  precision  better than 0,84% and resolution less than 0.5 N. The Measurements are presented on a computer screen and easier visualization to specialists, mainly  physicians,physiotherapists  and  occupational  therapists. Using  the  system were  to  investigate  the distribution of weight  in  the plantar region of 100 normal  subjects and 10 hemiplegic patients. There were determined  the relationship  between weight  distribution  on  the  forefoot  right  and left, hemiplegic patients and normal patients, with  the  implemented system.
