“…Port workers present a high mean of age, which causes dehydration of the intervertebral disks, leading to degeneration, instability and pain in the lumbar region. (10,11) It is also worth noting the worker's compromise by systemic conditions, such as obesity, which may contribute to the increase of lumbar lordosis, favoring the occurrence of mechanical low back pain, (12,13) which is an etiology condition different from lumboischialgia. Therefore, these conditions require clinical reasoning to be characterized in an accurate physical examination and a complete neurological evaluation, that comprise different clinical techniques, such as palpation, in which it is possible to identify the hypertonia in paravertebral muscles, as well as to identify mechanical, compressive, root or spinal nerve compromise with the lumbar spine, from the Lasegue's maneuver, (10) detecting the possibility of lomboischialgia.…”
