Efectos de una técnica manual de tracción vertebral sobre el patrón de movimiento lumbo-pélvico y activación del erector espinal durante la flexo-extensión del tronco en pacientes con dolor lumbar

Zusammenfassung

Objective To determine the behavior of the erector spinae and patterns lumbo-pelvic movement during flexion and extension movement of the trunk, following the application of a manual technique of lumbosacral decompression in patients with low back pain. Material and methods 10 subjects with non-specific low back pain participated in the study. Surface electromyography recordings of the activity of the lumbar erector spinal muscles (L3 and L5, bilateral) and recordings of the lumbo-pelvic mobility were performed during trunk flexion and extension. These recordings were made before and after the application of the technique. Results After comparing the results of the parameters studied before and immediately after the manual technique no significant differences in either the behavior of the erector spinae, or the pattern of lumbar-pelvic movement found. Conclusions This study suggests that this manual technique of lumbosacral decompression, by itself, is not enough to produce immediate changes in patterns of lumbar-pelvic movement and activation of the erector spinae.
