ABSTRACT
Introduction: the lumbosacral radiculopathy is a disease that tends to be chronic and it causes disability in patients who suffer from it. For a proper treatment, it is important the implementation of neurophysiologic studies because they are highly adequated to get to a diagnosis, improvement and prognosis.Objective: to determine the electromyography behaviours in the lumbosacral radicular complaints in elderly persons.
Method: A case- control study was carried out in the patients admitted due to low back pain and diagnosed with an herniated disk in the neurosurgery department of Carlos Manuel de Céspedes Hospital from January, 2006 to January, 2011. The study included 293 cases who were complaining of low back pain, a sample of 25 patients were diagnosed electromiographically with lumbosacral radiculopathy due to an herniated disk and a control group of 75 elderly persons apparently healthy who were assisted for other causes in the consultation of orthopaedic, neurology, neurosurgery and neurophysiology.
Results: In the patients suffering from a herniated disk, the isolate contraction pattern was predominant in a 72 %, as well as the fibrillation potentials in a 24%, the acute positive waves in a 12 % and potentials of action in the poliphasic motor unit (88%). The myelinated harm was predominant in the 52% of the cases.
Conclusions: The electromyography showed radicular complaints to a certain degree in all the patients of the sample and it was not the same in the control groups.
