ABSTRACT
Aims:
This study aimed to evaluate the changes in the spine curvatures and the sensations caused by different types of seats standard, ischial support and salli.Methods:
The analyzes were performed by the kinematics and scales of discomfort and pain in 14 healthy subjects. The data collection occurred in three days, one day for each type of seat. The subjects answered questionnaires and were assessed for placement of kinematic markers used to measure the thoracic, thoraco-lumbar and lumbar angles. Each trial was conducted in a sixty-minute period on each chair. Results andconclusions:
The results showed that the salli seat type causes larger lumbar angles, which is consistent with the maintenance of lumbar lordosis. Likewise, the salli seat showed smaller thoraco-lumbar angle, which is consistent with smaller inferior thoracic kyphosis. Paradoxically, the ischial support seat produced less discomfort and pain than salli type. And finally, the longer the sitting position was the higher the score on the discomfort scale.(AU)
