Could Thermal Imaging Supplement Surface Electromyography Measurements for Skeletal Muscles?

1) Background: The aim of this study is to present the results experiments in which surface electromyography (sEMG) and thermal imaging were used assess muscle activation during gait verify hypothesis that there a relationship case low fatigue level between sEMG-measured activation, assessed frequency domain, factors calculated as minimum, maximum, kurtosis, mean, median, mode from area interest. 2) Methods: Comparison activity recorded sEMG data for rectus femoris (RF), biceps femoris, tibialis anterior, gastrocnemius medialis (GM) with obtained infrared vision. 3) Results: Data 14 healthy volunteers 10 min treadmill are presented analyzed. analysis revealed statistically significant linear correlations RF (five moderate relationships) GM (one good relationship) nonlinear all examined muscles. Also, detailed protocol precise, repeatable examination presented. 4) Conclusions: Estimated electromyographic parameters found fatigue, suggests method useful use complement sEMG.
