Medial and lateral gastrocnemius muscle: instantaneous signal. Quiet standing.
Medial and lateral gastrocnemius muscle: instantaneous signal.
Tridimensional representation (3D) of the instantaneous differential voltage in the longitudinal direction on the surface of the gastrocnemius muscle.
Electrode grid of 8x16 electrodes spaced 10mm apart (70x150mm).
No propagating potentials are evident because of the pinnation angle. The signal is almost totally due to the end-of-fiber effect on the superficial aponeurosis.
