Abstract

This study demonstrated a high degree of equivalence between SEMG spike parameters and traditional time and frequency measures. The findings described in this article are important for patients who are unable to maintain constant-force contractions. The SEMG signal is stationary for constant-force contractions which is a necessary condition that must be met before applying spectral analysis techniques. However, before SEMG spike analysis can be advanced to regular clinical use, its limitations must be further understood.
