Lumbopelvic Movements Influencing the Perception of Back Pain in a Driving Static Posture, Made from a Device Placed on the Seat

Introduction: Evidence shows an association between lbp and sitting posture there. Moreover, the macro repositioning effected on the seat is the natural response of the body because of the perceived inconvenience versus time prolonged, but the evidence shows that these movements made by the subjects not mitigate low-back pain and the perception of discomfort increases. Materials and methods: Several experimental studies were conducted for macro repositioning movements using a seat, a device placed on it developed, the following variables were recorded: 1) the variation of the angle of the seat under the criteria of less biomechanical demand and lower perception of discomfort, 2) the rate of change of the angle of the seat under the criteria of lower perception of instability and 3) how often you should perform these repositioning. Results: The macro repositioning are performed with a frequency of 12.6 minutes and speed without percep¬tion of instability is 0.17 rad/s; the seat tilt affects intradisk pressure (sig 0,003) and in negative inclinations of the seat charge which is not transmitted to the ischial tuberosities is transferred to the knees and feet. Discussion: This studio is located in the validation of their main hypoth¬esis, which if true, is to create new tracks in the design of seats to alleviate lumbar pain in drivers working in prolonged sitting position.
