Symmetric Tonic Labyrinthine

A retained STNR has been linked to difficulties with upper and lower body integration and hand-eye coordination, both of which are needed for adequate performance in physical activities.  The STNR has also been linked to poor attention, posture and reduced ability to sit still. The retained STNR may lead to slow visual accommodation (speed of refocusing between different visual distances), which can affect speed and accuracy when trying to catch a ball or copy from a blackboard or book.  

Additional effects if the STNR is retained: 

  • Posture (both sitting and standing) often wrap legs around chair. 

  • Upper and lower body integration.

  • Attention/concentration

  • Hand-eye coordination

  • Swimming (upper ext/lower flexes) 

  • Re-establishment of binocular vision (difficulty copying, catching a ball, accommodation takes longer) 

  • "W" seated position 

  • Messy eater

  • Vertical tracking (math)
