Posture & Torso Alignment (PTA) System


TheraTogs Posture & Torso Alignment (PTA) System is the preferred starting point for seeing improvements in upper body alignment and posture by taking advantage of our neuromotor system’s ability to learn and adapt to corrected alignment.

The PTA system consists of two garments and a small set of straps – a basic system that’s simple to apply, cost-effective, and easy to learn how to use.

Leverages the human ‘upright’ response to improved functional alignment

The PTA System includes the same TankTop and Hipster as the Full Body System, and is a good introduction to working with and using TheraTogs because you can see immediate results. The PTA system is simple to use, it only takes a few minutes to put on, and it gives the wearer postural and torso retraining all day long.

By focusing on trunk stability and postural alignment, you’ll lay the foundation for even more advanced outcomes.

Our Postural Alignment Algorithm will help clinicians determine their best options in managing postural alignment.

Product Specifics

If you don’t see your indication in this list talk to your clinician or call us to see if the Posture & Torso Alignment System might be right for you.

  • Hypotonia
  • Flexible kyphosis
  • Flexible lordosis / excessive pelvic tilt
  • Difficulty maintaining midline trunk and sitting balance
  • Weak trunk muscles
  • Shoulder protraction & scapular abduction

Working together, client, clinician and caregiver can achieve these and similar outcomes with the PTA System:

  • Shortening of trunk muscles – letting them work in, and adapt to, a shortened state
  • Improved posture
  • Improved respiratory capacity
  • Reduced deviations between thorax and pelvis
  • Increased sensory awareness
  • Gentle shoulder retraction and scapular stabilization

Measure and Fit Guidelines

Designed to be applied in three easy steps

Step One: Fit the Garment. The Hipster provides hip stability and attachment points for the TankTop and for strapping. The TankTop hugs the upper trunk. Together, the Hipster and TankTop create a full body ‘field’ for postural-assist strapping.

Step Two: Align the Spine. Choose from among 3 strapping applications to improve upper and/or lower trunk extension. If needed, strap to retract protracted shoulders and stabilize the scapulae.

Step Three: Add Advanced Strapping. Choose a strapping application to assist oblique and/or transverse abdominals to complete the core application. Strap from pelvis to thorax to reduce excess anterior pelvic tilt.
