Methods of Muscular Electrostimulation

  • H. Thoma

Abstract

Since Galvani 1791 pubhshed his experiments on the frog thigh, we have known the principle of functional electric stimulation [1]. There is a hyperbolic connection between the stimulation current and stimulation time. Therefore we need a high current for stimulation with a short impulse. A pulse length of 1 up to 5 ms normally depolarises the fibre. Stimulation is applicable in either muscle or nerve fibre. If we fix the electrodes close to the nerve, stimulation has some advantages:
  • The inhomogeneous electric field allows a smooth movement.

  • Less energy for depolarisation of even larger muscle areas (1–5 mA) is necessary.

  • Knowledge of what kind of fibres we are going to stimulate (afferent and efferent).

  • Less movement of the electrode area during stimulation.

  • Less sensivity in most of the cases.
