The thoracic spine, as viewed from the side, should have a natural 'oval or egg shell'-shaped curve with slightly more curvature in the mid and upper region. This curve is called the Thoracic Kyphosis (Figure 3 above). Lifting injuries, falls, poor posture, and poor ergonomics all contribute to abnormal Thoracic Kyphosis (Figures 1,2,4, and 5 above). Poor or abnormal Thoracic Kyphosis detrimentally effects your muscles, spinal ligaments and discs, nerves, bones and even the internal organs in the chest and abdominal cavities. In short, abnormality of the Thoracic Kyphosis can contribute to a number of unhealthy ailments.
The Denneroll is a Thoracic orthotic device developed by chiropractors. Its unique design provides a gentle but effective stretch that assists in the correction of abnormal Thoracic Kyhposis (Figures 6-8 above). When properly used, the Denneroll can assist in relief of pain, muscle tension, and improved postural appearance. Enhanced patient comfort and improved health are the goals.
There are three regions of Thoracic Corrective setups appropriate for Denneroll application: Lower Thoracic, Mid-Thoracic, and Upper-Thoracic. See Figures 9-11 above. Only a radiographic and postural analysis can determine which Denneroll placement is right for the individual patient. To be effective the Denneroll device should only be used on a firm surface such as the floor, or a bench.
When finished with your DENNEROLL session, do not raise straight up. Roll to your side off the device and once comfortable sit up.
The thoracic support blocks can be used for minimizing posterior translation of the thoracic spine. Fiures 12, 13, and 14 (above) show varying degrees of translation. The translation block also has a compression strap attachment (shown below) which is used to help to combat against strong forward head carriage.
