Some of the leading causes of trigger point activations in the rectus abdominis include acute trauma and occupational strain. For instance, trigger points are likely to occur near an abdominal scar.
Paradoxical breathing often develops in response to the soreness of abdominal surgery. Then this breathing pattern perpetuates these trigger points.
What stresses rectus abdominis? Some factors are overall fatigue, emotional tension, viral infections, straining due to constipation and poor posture. Additional factors include cold exposure, carrying a backpack or walking uphill.
Sometimes, whether in spite of or because of regular abdominal workouts, active trigger points develop. The abdomen sags as the trigger points inhibit the muscle’s supportive function. Janda mentioned that the abdominals are generally prone to inhibition. They are a key muscle group in Janda’s Lower Cross Syndrome.
