Cortical Excitability and Typing Performance After Action Observation and Motor Execution
Sponsor: University of Sharjah
Summary
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.

Conditions
Interventions
Motor Execution Typing Task
Participants will perform a 3-minute typing task using custom-designed text that emphasizes index finger use. This task is designed to actively engage the motor cortex and will be administered in a controlled environment using standard posture and equipment. The task aims to elicit changes in cortical excitability, which will be measured pre- and post-intervention using TMS.
Action Observation of Typing Task
Participants will observe a 3-minute first-person video of an individual typing the standardized text. The video is designed to activate mirror neuron systems through visual engagement with a familiar motor task. It will be shown once in a controlled setting, and post-assessment of cortical excitability will follow immediately after.
