Abstract
This study aims to explore how Delayed Onset Muscle Soreness (DOMS) can induce changes in lumbar erector spinae neuromuscular activity, trunk kinematics and lumbar spine stiffness, and how DOMS can be confirmed as an experimental pain model for studying LBP mechanisms. Seventeen adult participants were asked to perform four sets of 25 repetitions of trunk flexion and extension. During these tasks, trunk muscle activity, spinal stiffness and kinematics were assessed. Our results suggest that in the presence of DOMS, significant increases in lumbar spine stiffness whereas only limited changes in flexion relaxation phenomenon parameters are observed.
期刊介绍：
Journal of Electromyography & Kinesiology is the primary source for outstanding original articles on the study of human movement from muscle contraction via its motor units and sensory system to integrated motion through mechanical and electrical detection techniques.
As the official publication of the International Society of Electrophysiology and Kinesiology, the journal is dedicated to publishing the best work in all areas of electromyography and kinesiology, including: control of movement, muscle fatigue, muscle and nerve properties, joint biomechanics and electrical stimulation. Applications in rehabilitation, sports & exercise, motion analysis, ergonomics, alternative & complimentary medicine, measures of human performance and technical articles on electromyographic signal processing are welcome.
