Summary

Patients suffering from neurological disorders often exhibit unwanted sensorimotor activities e.g. spasticity, hypersensitisation, hyper- and dystonia and motor disabilities. Currently, several therapeutic interventions are developed and implemented to overcome these unwanted activities e.g. transcutaneous electrical stimulation (TES), oral medication, botulinum neurotoxin injections, local anaesthetics, rehabilitation robotic training and surgery. However, these therapies offer varying results. Compared to analgesic drugs, TES is associated with fewer side effects and has therefore become a popular therapeutic strategy to treat these unwanted sensorimotor activities. To enable this TES strategy, surface electrodes are attached to the skin overlying the site of pain. Next, a low-frequency electrical current (LFC; 1-100 Hz) is applied. However, this low-frequency current acts as an excitatory agent and results in muscle contraction. Therefore, this technique cannot be used to treat unwanted motor activities.

Electrical stimulation with medium-frequency alternating electrical currents (MFAEC; 2-50 kHz) can inhibit peripheral motor nerve activities and force production, when implanted directly on top of the peripheral nerve of interest. However, this strategy is rather invasive. Thus, the administration of transcutaneous medium-frequency alternating electrical currents (tMFAEC), i.e. administration of electrical currents through the skin, might offer a solution. However, the effects of tMFAEC on motor nerve inhibition remains largely unknown. Theoretically, the administration of tMFAEC on the sensory nerve may even result in partial or complete (reversible) nerve block thereby serving as an anesthesia in order to perform surgical or painful procedures.
