Recent applications of functional electrical stimulation to stroke patients in Ljubljana.

Functional movements can be restored after stroke by portable neuroelectric stimulator controlled by the patient. This field of activity is called functional electrical stimulation (FES). A common example of FES is electric stimulation of the peroneal to prevent dropfoot. A more sophisticated multichannel enables stimulation of more than one paralyzed muscle of the leg. This system is used temporarily to facilitate recovery of muscle function following stroke. Upper extremity FES systems have proven more difficult to develop than lower extremity systems designed to improve walking. A single-channel hand stimulator is available to assist finger movements.

Rigidity in parkinsonism: characteristics and influences of passive exercise and electrical nerve stimulation.

Rigidity was measured during sinusoidal passive movements of the ankle joint in 7 patients with parkinsonism. Velocity-dependent changes were observed, less marked than in spasticity and expressed in a different way in flexor and extensor muscles: a mild decrease in resistive torques at faster stretching of dorsal flexors and an increase in resistance on stretching of plantar flexors. Dorsal flexors also frequently showed shortening reactions. Passive exercises and electrical stimulation of the peroneal nerve resulted in decreased electromyographic responses to stretch, smoother passive movements and in improved voluntary contraction.
