Eficacia de la infiltración de ozono paravertebral lumbar y en puntos gatillos como coadyuvante del tratamiento en pacientes con dolor lumbar crónico y lumbociatalgia crónica en el síndrome doloroso miofascial aislado o acompa?ado de otras patologías

摘要

Background: After the first episode of low back pain, recurrence persists for a year or more in 25 to 60 %, affecting economically active population, causing disability and 80 % absenteeism. Objective: To evaluate the effectiveness of the use of ozone injection technique with paravertebral lumbar and trigger points along the drug treatment and rehabilitation in patients with chronic low back pain and sciatica due to chronic pain syndrome myofascial isolated or accompanied other pathologies. Methods: A non-probability, experimental type double-blind controlled. We studied 43 patients (22 experimental and 21 control). The experimental group received lumbar paravertebral ozone trigger points and more drug treatment and rehabilitation. The control group received drug treatment and rehabilitation. Was applied in both groups VAS, Oswestry and measuring the degrees of flexion of the trunk at the beginning, two and four weeks after initiation of therapy. Results: The application of ozone and lumbar paravertebral and trigger points along the drug treatment and rehabilitation in the management of patients with chronic low back pain and sciatica, compared to just drug treatment and rehabilitation, was more effective, with statistical significance (p < 0.05) to decrease the intensity of pain (90.5 %), functional disability (90.5 %) and increased degrees of trunk flexion (85.7 %) versus 40.0, 70 and 75 %, respectively, at four weeks after initiation of treatment. It is evident improvement in patients with MDS or accompanied isolated lateral recess syndrome, facet syndrome, disc herniation varying degrees except the central extrusion. Conclusions: The ozone infiltration paravertebral lumbar and trigger points along the drug treatment and rehabilitation was more effective, to reduce pain and functional disability and increase the degrees of trunk flexion early in patients with chronic low back pain and sciatica due to chronic isolated or accompanied by other conditions that cause back pain.
