Regional Thoracoabdominal Mobility Responses to Integrated Myofascial Release in Healthy Adults

Participants will receive a single standardized session of integrated myofascial release therapy targeting selected thoracic and abdominal myofascial regions. Regional thoracoabdominal mobility and thoracic excursion will be assessed before and immediately after the intervention.

Participants will receive one standardized session of integrated myofascial release therapy applied manually to selected thoracic and abdominal myofascial regions. The intervention will include sustained, low-load manual techniques directed at the soft tissues and fascial structures of the thoracoabdominal region. The same standardized treatment sequence will be applied to all participants by a trained physiotherapist. Regional thoracoabdominal mobility and thoracic excursion will be assessed immediately before and immediately after the intervention.

Regional thoracoabdominal excursion will be assessed using a tape measure at predefined anatomical levels of the thorax and abdomen. At each level, the difference in circumference between maximal inspiration and maximal expiration will be recorded in centimeters. Changes from baseline to immediately after the integrated myofascial release intervention will be analyzed separately for each anatomical level, allowing comparison of regional mobility responses.
