Abstract :
This paper is intended to present an assessment of the experimental results of a previously proposed muscle conduction velocity distribution (CVD) estimator. The performance of the proposed technique was seriously deteriorated when applied to experimental data. The causes for this decline were evaluated by introducing real-world errors in the model parameters and looking at how sensitive the estimator is to these. The simulation results show the high sensitivity of the estimator to parameter errors. The similitude found between the simulation results and the CVD estimates obtained on experimental data helped confirm this observation as well. Given the sensitivity observed the proposed technique is not practical for muscle dimensions such as those found in the biceps brachii.
