Brief summary
Studies on the improvement of body image or body perception have proven their effectiveness in different clinical situations such as pain management and chronic pain treatment. The aim of this study is to evaluate the hand lateralization cognitive task by recording Electroencephalography (EEG) signals from different personal perspectives in amputees. In this study, the paradigm in which personal perspectives are evaluated over the hand lateralization task will be applied to amputees and healthy volunteer participants. Data will be recorded via EEG and Eprime software program.
Detailed description
The aim of this study is to evaluate the hand lateralization cognitive task by recording Electroencephalography (EEG) signals from different personal perspectives in amputees. In this study, the paradigm in which personal perspectives are evaluated over the hand lateralization task will be applied to amputees and healthy volunteer participants. It was planned to enroll two groups to the study. One group is named amputees the other one is control. Control group will be matched in terms of age and gender with the amputees group. Before hand lateralization test, participants will be evaluated regarding eligible criterias and EEG paradigm regarding hand lateralization will be performed for each participant. Both groups (Amputees and Control) will complete hand lateralization program for at least 10 days. The test will be sent each day on an online system. Participants' performances will be recorded via online system. Following 10-day period, EEG paradigm regarding hand lateralization will be performed for each participant, again. Before and after comparisons will be analyzed. Data will be recorded via EEG and Eprime software program. EEG-Event Related Oscillation (power spectrum, phase locking) analysis will be performed for each frequency bands: alpha, theta, beta, gamma. Eprime analysis will be performed for the data of reaction time and accuracy rate.
Interventions
BEHAVIORALHand Lateralization Test
Before hand lateralization test, participants will be evaluated. Both groups (Amputees and Control) will complete hand lateralization test for at least 10 days. The test will be sent each day on an online system. Participants' performances will be recorded via online system. After hand lateralization test, participants will be evaluated.
