Hello,
I am working on a project looking at quadriceps torque steadiness or control (aka: variability, fluctuations) during submaximal isometric and isokinetic target-matching knee extension contractions.
Our lab has completed previous studies looking at torque steadiness using the coefficient of variation of torque (= torque standard deviation/torque mean * 100) as our primary outcome, but we were wondering if anyone had any suggestions for an alternative analysis techniques to quantify unsteadiness or poor stability during muscle contractions?
One analysis we are interested in using is approximate entropy. Any thoughts on the appropriateness of approximate entropy to quantify the steadiness/control of an isometric or isokinetic contraction?
Thank you for your thoughts,
- John
