Test of Sensory Functions in Infants (TSFI)

Purpose: Determine whether and to what extent an infant has sensory processing deficits

Age: 4-18 months

Time: 20 Minutes

The Test of Sensory Functions in Infants (TSFI) 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. It provides an overall measure of sensory processing and reactivity, as well as scores on the following subdomains:

• Reactivity to Tactile Deep pressure
• Visual Tactile Integration
• Adaptive Motor Function
• Ocular Motor control
• Reactivity to Vestibular Stimulation

Composed of 24 items, the TSFI can 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 can 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.
