The core is a box structure made up of the abdominal muscles in the front and the sides, the paraspinal and gluteal muscles at the back, the diaphragm at the roof, and the pelvic floor and the hip girdle muscles as the floor.

Biofeedback is a valuable tool for assessing and training muscle power in the lower back region. It involves using pressure biofeedback units to measure the strength of core muscles such as the transversus abdominis and lumbar multifidi. Pressure ranged from zero to 100 and zero point means weak muscle and 100 means high power muscle

It is a scale ranged from zero to ten and zero point indicate there is no pain and ten point indicate the worst pain
