Abstract
The vast majority of hip or knee arthroplasty finishes with improved limb functional status. Despite this, some patients do not recover; they "save" the operated limb; they cannot trust it. This also happens in patients whose range of motion and muscle strength are rated as very good. It is possible, therefore, that the causes must be located in the movement initiating centre, in the motor cortex. We can link the activation and changes in the metabolism of the cerebral cortex, e.g. during limb movement, with the changes in bioelectrical activity visible in electroencephalography (EEG). Conclusions: Our literature analysis shows that so far, no study has been conducted to check whether EEG activity changes over the sensory-motor region after lower limb arthroplasty. We propose the design of such a study with an analysis of potential difficulties that would have to be overcome by the team undertaking the challenge. The obtained data could be the basis for neurorehabilitation using the EEG biofeedback method. Effective interventions would further improve the quality of life.
