The goal of this clinical trial is to evaluate the effect of pressure biofeedback training on abdominal muscle strength and quality of life in adults following ventral hernioplasty. The main questions it aims to answer are:

• Is there a significant effect of pressure biofeedback training on abdominal muscle strength in patients following ventral hernioplasty?
• Is there a significant effect of pressure biofeedback training on quality of life in patients following ventral hernioplasty?

Researchers will compare the effect of adding pressure biofeedback training to a conventional physical therapy program versus a conventional physical therapy program alone to determine whether pressure biofeedback training provides additional benefits in improving abdominal muscle strength and quality of life following ventral hernioplasty.

Participants in the study group will receive pressure biofeedback training in addition to the conventional physical therapy program, while participants in the control group will receive the conventional physical therapy program only.
