Retention of TLR restricts the side-lying, roll-over, creeping and lying to seated ability of the child.7 In developmentally-delayed child, like CP, TLR retention causes the increased flexor tone with the child in prone lying position.8 While there is most likely increase in extensor tone in CP child with supine lying positioning, it leads to stereotypical movements as tonic reflexes are retained at brainstem level.9 This retention of primitive reflex make the CP child uncomfortable in seated position and indirectly has a marked effect on the attention span and learning skills of the child.9
