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.

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
