Efectos de un programa de fortalecimiento funcional del CORE utilizando dinamometría electromecánica funcional sobre el dolor, incapacidad, fuerza y calidad muscular en sujetos con dolor lumbar agudo no específico

Abstract

Based on the above background, the main objective of this Doctoral Thesis was: To determine the effects of a functional trunk strengthening program using a FEMD on pain, disability, strength, and muscle quality in subjects with non-specific low back pain. Given the temporal restrictions imposed by the pandemic, we will only be able to give a partial answer to this objective, for this we have four investigations published in journals indexed in the Journal Citation Reports plus a research project in development, whose objectives were: (1) determine the quality of evidence of articles evaluating isokinetic trunk strength in subjects with acute low back pain and healthy subjects and establish reference values of isokinetic trunk strength in subjects with acute low back pain (study 1); determine the quality of evidence and examine the reliability and most reliable protocol of trunk strength assessment with an isokinetic dynamometer in patients with low back pain (study 2); explore the reliability and determine the most reliable protocol of trunk extensor strength assessment using a FEMD (study 3), and analyze muscle quality and compare the ratio of conventional and functional trunk strength using different strength variables collected under isokinetic and isometric conditions (study 4). In addition, to determine the effects of isokinetic trunk training on pain intensity, disability, and isokinetic trunk strength in patients with non-specific low back pain (study 5).
