Wheelchair's users spend most of their
time seated in the same position. Over the time due to unrelieved pressure, shearing forces, friction, humidity, temperature, continence, and medication, these persons tend to develop several injuries. During themovement of the wheelchair through the use of the arms, torso and legs are not only subjected to the pressure
resulting from body weight but also a friction force, some
temperature increment and humidity from sweat. This leads to a series of problems being one of the most serious, pressure ulcers. Despite all the health problems, this is also very uncomfortable
for any person especially for a handicap person, since
he/she is already in a conditioned status. The main corrective action regarding pressure ulcers is, to remove the pressure, changing the position ever two or four hours, depending on the patient . Over the years, if there is nomovement or exercise of the lower limbs, the risk of developing pressure ulcers increases.
Mainly due to the diminution of muscle volume in the legs, itincreases the zones of skin overlying bone prominences. The primary objective of this
study was to demonstrate that thermography can be used to accurately predict whether or not a high regional nerve blockwas successfully performed.
