Acute Effects of a Single-Session Body Awareness Intervention on Cortical Activity and Interoceptive Accuracy
Sponsor: Ertugrul Deniz Kose
Summary
This study will examine the immediate (acute) effects of a single, 30-minute body awareness session on brain activity and interoceptive accuracy in healthy young adults aged 18-25. Participants will be randomly assigned to one of two groups: an intervention group, which will complete a structured body awareness exercise based on Basic Body Awareness Therapy, or a control group, which will rest quietly for the same amount of time without any specific instructions. Before and after the session, brain activity will be recorded using a portable, 8-channel EEG device, and interoceptive accuracy will be measured with a heartbeat perception task, in which participants try to count their own heartbeats without checking their pulse. The main goal is to determine whether a single body awareness session produces measurable changes in EEG brain wave patterns (theta, alpha, beta, and gamma bands) and in the accuracy of heartbeat perception, and whether these two types of change are related to each other.

Conditions
Interventions
Basic Body Awareness Therapy Intervention
A single \~30-minute body awareness session delivered in a quiet, well-ventilated room with minimal distraction. The session follows a structured sequence of low-intensity, pain-free, non-strenuous body awareness exercises performed in supine, sitting, and standing positions, guided verbally by a trained physiotherapist or researcher. The session focuses on conscious awareness of posture, contact points, breathing, and movement quality rather than physical performance, strength, or flexibility. Participants are instructed to move without forcing and to report any pain, dizziness, or discomfort during the session.
No Intervention/Sham Comparator
A single \~30-minute quiet resting session delivered in the same room and under the same environmental conditions as the intervention session. Participants will be asked to remain in a comfortable seated or supine position, close their eyes or fix their gaze on a stationary point, and rest quietly for the full duration. No specific breathing, body awareness, or movement instructions will be given. Participants will be informed that they may notify the researcher if they experience any discomfort.
