Summary

The study investigates the capabilities of peripheral magnetic stimulation (PMS) as a tool for creating somatosensory sensations of various submodalities and analyzing the dynamics of bioelectric signals of the brain (using encephalography (EEG)) in healthy participants and participants with upper limb amputations. During the experiment, the participants' subjective sensations and EEG activity are recorded in response to magnetic pulses of varying intensity. In addition, the continuous PMS stimulation protocol and its effect on phantom sensations in participants with amputations will be tested for subsequent implementation in clinical practice.

Conditions

• Phantom Limb Pain

Interventions

Type	Name	Description
DEVICE	Procedure: Peripheral Magnetic Stimulation (PMS)	PMS is a non-invasive neuromodulation technique used to treat chronic pain. Procedure starts with sensory mapping, localisation of the hotspot and detection of sensory threshold. Then two protocols of PMS are implemented: 5 blocks of PMS of varying frequency and 1 block of rPMS.
OTHER	Electroencephalography (EEG)	EEG is a technique commonly used for the registration of brain activity. The procedure is non-invasive, electrodes are placed on the scalp of the participants. The recording is made simultaneously with the PMS.
