Pain may refer to the lower abdomen and sometimes the lower back.
It can cause deep aching, burning, or sharp pain in the lower abdominal region, and may contribute to discomfort or restricted movement in the lower back and pelvis.
Pain Pattern
• Potential Causes
• Overuse or repetitive activities involving core stabilization and compression, such as heavy lifting, prolonged sitting, or certain sports.
• Poor posture, especially excessive anterior pelvic tilt or slouched posture.
• Muscle imbalances between the transverse abdominis and other abdominal and back muscles.
• Trauma or injury to the abdominal or pelvic area.
• Prevention Tips
• Use proper techniques and form during core stabilization and lifting exercises to avoid overloading the transverse abdominis.
• Incorporate regular core strengthening and stabilization exercises.
• Ensure proper warm-up and cooldown routines before and after exercise.
• Maintain good posture and ergonomics during daily activities.
• Ensure balanced strength training to avoid muscle imbalances.
