In rehabilitation, we find several situations that needs the reduction of load over the osteoarticular and muscular structures, aiming the reduction of load and relief of pain. Thus, we studied the reduction of load in plantar area due to walking aids, specifically canes, with computadorized podobarometer ("FSCAN"). Two types of canes, the common and the quad cane were evaluated. Support time and peak pressure of the heel were quantitatively evaluated in eight normal voluntees (without previos ankle, knee or hip complaints). All volunteers used the cane at right hand. We obtained more than 60% reduction of plantar vertical force (newton) at the left side and approximately 50% at the fight side, with both canes. Furthermore, increased gait time of' about twice and reduction of peak pressure of the heel, with both canes were observed. All results showed statistic significancy.
Conclusion: Walking aids (canes) are good methods of plantar vertical forces for both lower limbs.

Objectave- The present work intended to test the confidence of the quantitative datas provided by computadonzed baropodometry based in three comparisons: between static vertical force on the three regions of the foot and weight, between vertical force on the three regions of the foot during gait and weight, and between peak plantar pressure on the three regions of the foot during gait and weight. It was used body weight because the calibration of the equipment is done in relation to the body weight of the patient.
Methods: It was selected ten volunteers without foot pain complaints, age between 27-54 years, 6 women and 4 men. The equipment used was the FSCAN version 1,821 (Tekscan, Boston MA), with new insoles.
Results: At the static assessment, the correlation between vertical force and weight was statistically significant only to the midfoot. At the assessment during the gait the correlation between vertical force and weight was statistically significant for all regions of the foot and the correlation between peak plantar pressure and weight was statistically significant only to the midfoot.
Conclusion: The computadorized baropodometry is an exam that provides confidence qualitative dams; on the other hand, the quantitative datas must be interpreted with caution due to uncount variables that are involved.
