Full text available on request.Abstract
During walking on a prosthesis after a transfemural amputation, the reorganization in the motor and somatosensory cortical maps can influence brain activity and the ability of motor learning. However, it is uncertain what changes in brain activity due to walking on a prosthesis may be expected. The current exploratory study therefore tries to gain first insight in the influence of walking with a dummy prosthesis by healthy individuals on brain activity in the frontal and motor cortices. Participants were equipped with a 32-electrode wireless electroencephalography (EEG) system with additional two accelerometers on the upper leg and one on the trunk (L3-L4). The measurements included one block of 4-minute normal walking and three blocks of 4-minute walking with a dummy prosthesis, all on a instrumented treadmill with a speed of 0.9 m/s. Brain activity was analysed and displayed in an event related spectral perturbation (ERSP). Results show an enlarged event related desynchronization (ERD) in the theta and alpha frequencies, lasting for most of the double support and the right swing phase, when walking on a dummy prosthesis in comparison to normal walking in both the motor and frontal cortex. Additionally, the ERD diminished after more experience walking on the dummy prosthesis. Results suggest that walking on a dummy prosthesis requires more motor learning, preparation and execution than normal walking and this effect will reduce after more experience with walking on a dummy prosthesis.
