Neural observer based spasticity quantification during therapeutic muscle stimulation.

Repetitive peripheral magnetic stimulation (RPMS) is an innovative approach in treatment of central paresis, e.g. after stroke.

A fronto-parietal network is mediating improvement of motor function related to repetitive peripheral magnetic stimulation: A PET-H2O15 study.

Repetitive peripheral magnetic stimulation (RPMS) is a focused and painless stimulation method, in which muscle contractions are elicited by depolarization of the terminal motor branches. Clinical-experimental investigations on different disorders of sensorimotor integration in the last decade have shown that RPMS can be used for the rehabilitation of motor functions after stroke. It is supposed that this therapeutic effect is based on the RPMS-induced proprioceptive inflow to the CNS.

Modulatory effect of repetitive peripheral magnetic stimulation on skeletal muscle tone in healthy subjects: stabilization of the elbow joint.

To investigate the role of repetitive peripheral magnetic stimulation (RPMS) on the postural component of motor performances, the long-lasting modulatory effect of RPMS on the stabilization of the elbow joint was examined in 13 healthy subjects. The resistance against very slow passive movements in the relaxed state was recorded simultaneously with the electromyogram (EMG) of the forearm extensor and flexor muscles. The experiments show that RPMS performed on the forearm flexor muscles increased the degree of stabilization of the elbow joint, whereas RPMS on the forearm extensor muscles caused a decrease in stabilization.

Modulation of sensorimotor performances and cognition abilities induced by RPMS: clinical and experimental investigations.

The investigations presented in this chapter lead to the conclusion that proprioceptive afferent inflow to the CNS induced by RPMS elicits various modulatory effects in sensorimotor and cognitive systems. Since the build-up of the conditioning effects is delayed and the effects itself are long-lasting, it has to be assumed that these effects are caused via neuromodulators. Therefore, the presented approach is promising to improve sensorimotor and cognitive disturbances after lesions in the CNS, e.
