... The theory of the Sherrington principle as one of the pioneers of the concept of proprioceptic neuromuscular stimulation in the human body to control motion in the human body explains that imbalance in the lower back muscles will result in a complete change in posture in the lumbosacral joint, hip joint and pelvic joint region 15 . Cases such as scoliosis, lumbar hyperlodosis, lower back syndrome or commonly known as lower quadrant syndrome will clearly provide biomechanical changes to the frontal muscles such as hip flexors, abdominal muscles, back muscles to gluteus muscles so that there are inactive or weak muscle regions and overactive or over tight muscles 16 . The important role of mulligan is to normalize and activate inactive muscles which cannot be done by conventional stretching which only focuses on intervening tight muscles 17 . ...
