A MECHANOMYOGRAPHIC ANALYSIS OF CONTRACTION TIME IN LUMBAR SPINE MUSCULATURE; CONTROL DATA
Keywords: mechanomyography, lumbar, sacral, lower back pain
AbstractMechanomyography (MMG) is an emerging diagnostic tool that investigates the contractile properties of human muscle tissues. This study investigated the contraction time (Tc) of localised muscles tissues within the lumbo-sacral spine in young, healthy participants (age: 20.92±2.02, BMI: 23.09±4.51, n=12). Analysis of 10 erector spinae muscle sites, as well as two over multifidus, found that muscle contraction time (Tc) was heterogeneous (p>0.05) and averaged 87.79ms. The data presented here represents control data for a future study into the diagnostic value of injury-related localised changes in Tc in chronic low back pain patients.
