Product Overview:

The TheraTogs ULTRA Wunzi Infant System is designed as a comfortable, foam-lined wearable therapy system that feels like a body hug for young infants. Addressing such indications as Hypotonia, Diplegic or Hemiplegic Cerebral Palsy, Torticollis, Athetosis, Cerebellar Ataxia, BPI, and Developmental Delay with the Wunzi Infant System should be accompanied by the direction of a therapist. Like all TheraTogs systems, the Wunzi is a Velcro½®-sensitive garment and strapping system that grips the skin. The patented composite fabric is elasticized with a stretch bias that favors good postural alignment - just the thing for a growing baby. The Wunzi Limb Kit includes grip-lined elastic straps that operate like external muscles and ligaments to improve functioning body and proximal joint alignment in order to optimize motor development. Extra limb cuffs and straps are also included. If ordering a new Wunzi system for the first time, we suggest ordering a limb kit.

Wunzi Key Features & Benefits-
With garment-embedded closure tabs, the "onesie" styled over-the-diaper Wunzi goes on quickly and easily. Simpler than 2 piece 'Togs, the Wunzi still utilizes the same core-strengthening straps and Goldtone fabric of the PTA System in a more manageable 1 piece set. Familiar Design means Improved Compliance!

Now with even longer Velcro tabs attached to the ends of the straps for a stronger anchor point- no more straps popping loose- and makes it easier to dress those wiggling babies!

The Wunzi system now includes limb cuffs and basic strapping to address a broader range of infant posture and alignment issues. The Limb Kit (described below) can still be purchased as a separate item for infants of any size who need significant abdominal support, lateral rotation, or iliopsoas muscle assistance beyond what the base system now provides. For clients wearing the larger sizes, you may need the Limb Kit for spinal or upper trunk extension to stabilize scapulae, or to support hip extension with abduction and lateral rotation.

Add the Wunzi Limb Kit to address any of the indications previously supported by TheraTogs' Upper or Lower Extremity strapping applications. The Wunzi combines the functions of three TheraTogs systems into one targeted solution. Use the Wunzi for infants and very young children to address any of the indications supported by TheraTogs garment and strapping applications for:
Posture & Torso alignment, balance, and strengthening
Lower Extremity alignment and function
Upper Extremity alignment and function

TheraTogs are an FDA-registered Class I medical device, providing gentle and prolonged muscle stretch and alignment that replicates the manual positioning and supervised therapy that the rehab clinician offers in a typical session. Commonly known as wearable therapy devices, the benefits of having thousands of repetitions in the garment to align correctly are readily apparent. These softgoods are not an off-the-shelf tool to be used without professional direction, however they are easy to wear and care for once properly fitted and instructed on how to best utilize them. The complete line of TheraTogs include the new Wunzi for infants, the PTA system, full body, lower extremity, autism/SPD and wrist/thumb. We hope that you will contact us with any questions that you may have before purchasing.

You May Need a Limb Kit When:
 -Developmental milestones become more complex
 -Distal fine tuning of limbs is needed (core/trunk milestones are met)
 -Integrative and intensive therapy program is matched with developmental milestones
 -The child sits independently, but additional strapping options are needed to meet position and
control objectives.
You Probably Need a Limb Kit When:
 -Sitting, crawling and rolling milestones are progressing quickly and the therapist requires
different control or positional strap lengths
 -A multifunctional team (PT, OT, SP) is working with the child with separate therapy goals.

Our daughter has the congenital diagnoses of arthrogryposis, lordosis, and severe scoliosis. Her doctors are a bit skeptical of her suit (I think because they just don’t have much knowledge on the topic), but her therapists are keen to use it and the straps. Our daughter is nine months old, and she currently has low/no muscle tone. Holding her when she is wearing her suit is like holding an entirely different baby. The suit makes it more difficult for her to pull back into her birth position, which was like a backbend/donut with her knees touching her head. I am THRILLED to finally have a TheraTog for her! We are looking forward to seeing how much she improves with this added assistance. Another mom turned me on to the suit, as her son was affected similarly to our daughter. She told us to talk to our PT to get one (the OTs want to learn about it, too, because they have said they have patients who could benefit, as well). And, since casting and bracing are so restrictive, and kiddos with AMC have to work so hard for any movement, this was a good route for us to explore. I am pleased thus far and HIGHLY RECOMMEND the TheraTog system. I am hopeful for a complete, miraculous recovery for our daughter. Her TheraTog will be a part of that.
