Immediate Changes in the Elasticity of Tissue and the Pain Pressure Threshold in Cesarean Scar Tissue After a Vacuum Intervention: An Open Clinical Trial.

: Cesarean section (C-section) scars are commonly linked to reduced tissue elasticity and increased pain due to adhesion formation. Addressing these concerns is essential to improving patient comfort and functional outcomes. This study aimed to assess the immediate effects of vacuum therapy on skin elasticity and pain sensitivity in C-section scar tissue. : Thirty-one women with C-section scars older than six months and less than two years participated in an open clinical trial. The skin elasticity was assessed using the Adheremeter, and the pain sensitivity was measured through the Pressure Pain Threshold (PPT) using algometry. The intervention consisted of a 15 min vacuum therapy session using the AeroFlow device that targeted the scar and surrounding areas. : The vacuum therapy intervention resulted in significant improvements in the skin elasticity at multiple assessment points, particularly in regions with fascial restrictions ( < 0.05). Concurrently, the PPT values decreased, indicating a reduction in pain sensitivity around the scar area ( < 0.05). These findings suggest that vacuum therapy may enhance tissue flexibility and alleviate pain in adherent C-section scars. : This study demonstrated the potential of vacuum therapy as an effective intervention to improve skin elasticity and reduce pain sensitivity in C-section scars. The Adheremeter-based assessment provided valuable insights into the biomechanical properties of scar tissue and supported its use in scar management protocols. This approach offers a promising, non-invasive strategy for personalized scar treatment, ultimately aiming to enhance patient outcomes and quality of life.
