For patients who may not be ready for the Thoracic Denneroll orthotic, the Thoracic Retrainer can be used as an introductory tool. Shorter and flatter than the Thoracic Denneroll, the Thoracic Retrainer is designed to gently stretch abnormal thoracic kyphosis back to normal. Like all Denneroll orthotics, the Thoracic Retrainer can be used in concert with our Thoracic Support Block System.
