Wunzi Infant System

The Wunzi Infant System was inspired by the familiar ‘onesie’ for infants. The Wunzi is designed for babies up to 26 lbs. and provides a customizable body hug that improves trunk alignment and stabilizes the core.

Description

TheraTogs Wunzi Infant System was inspired by the familiar ‘onesie’ for infants. Wunzi is designed for babies up to 26 lbs. and provides a customizable body hug that provides hours of carryover for rehab activities aimed at improving trunk alignment and stabilizing the core.

Postural control is an essential component of early intervention

Babies build trunk and neck control/strength before they gain functional skills. Trunk control problems that occur in infancy typically lead to long-term developmental deficits in limb use and movement.

The Wunzi system is designed to help very young clients by increasing sensory input while improving core stability. One of our most popular products, it supports therapy goals both during and between therapy sessions, providing essential carry-over.

The base system includes limb cuffs and strapping to create optimal posture, and the add-on Limb Kit operates like external muscles and ligaments to improve functioning body and proximal joint alignment for better motor development.

Goes on in seconds and over diapers

Caregivers love the over-the-diaper design which is quick and easy to put on. Closure tabs are embedded right into the garment – no loose tabs to keep track of.

Like all TheraTogs systems, the Wunzi is a comfortable, foam-lined, Velcro®-sensitive garment and strapping system that grips the skin. The patented composite fabric is elasticized with a stretch bias that favors good postural alignment – excellent for a growing baby.

Sizing

Guidelines for Wunzi System Measurements

For Torso Length measurement, measure down from C-7 (the big bone at the bottom of the neck) over the diaper and up to the child’s navel as shown below. Be careful to wrap the tape gently over the diaper. For Belly Girth, measure the infant’s belly circumference at the navel.
