This test helps you identify infants with sensory integrative dysfunction, including those at risk for developing learning disabilities as they grow older. The TSFI provides objective criteria that allow you to determine whether, and to what extent an infant has deficits in sensory functioning.

Designed for use with children aged from 4 to 18 months, the TSFI provides an overall measure of sensory processing and reactivity, as well as scores on the following sub domains:

  • Reactivity to Tactile Deep Pressure
  • Visual Tactile Integration
  • Adaptive Motor Function
  • Ocular Motor Control
  • Reactivity to Vestibular Stimulation

Composed of 24 items, the TSFI may be individually administered in just 20 minutes. The items require simple interaction with the baby, who is seated on the parent's lap, with bare feet and forearms exposed. The therapist touches the child or presents various stimulus materials and then records the child's reaction using clear-cut scoring criteria.

The TSFI may be used to assess infants with difficult temperament or developmental delays. It is also an excellent way to evaluate high-risk premature babies who may later develop learning problems. Brief, carefully constructed, and easy to administer and score, the test makes it possible to routinely screen infants for sensory integrative dysfunction.
