Cortical Excitability and Typing Performance After Action Observation and Motor Execution

Goal: This study will aim to investigate the effects of different motor stimulation strategies-motor execution (ME) and action observation (AO)-on cortical excitability and typing performance in healthy individuals. Recruitment: A total of 60 healthy university students will be recruited and randomly assigned into three groups: Motor Execution group (n=20) Action Observation group (n=20) Control group (n=20) Evaluation Tools: Transcranial Magnetic Stimulation (TMS) using DEYMED DuoMAG XT will be used to measure Resting Motor Threshold (RMT), Motor Evoked Potential (MEP) Amplitude, and MEP Latency of the First Dorsal Interosseous (FDI) muscle. Online Typing Test will be used to assess typing speed (words per minute) and accuracy (percentage of correct characters). Intervention: The ME group will perform a 3-minute typing task. The AO group will observe a 3-minute first-person video of typing. The Control group will not receive any intervention between assessments. All participants will undergo TMS and typing assessments twice, once before and once after the intervention.
