The JAY J3 TC Back’s patented internal thermal technology provides exceptional comfort and is designed to help with regulating body temperature. Evaporative cooling helps to dissipate moisture, while the heating system warms throughout the back.

Clinical benefit

Clinical benefit

The patented internal thermal technology in the JAY J3 TC wheelchair back may help those who have difficulty regulating their own body temperature, like Spinal Cord Injury (SCI) as well as Multiple Sclerosis (MS) patients. Especially those patients suffer from temperature dysregulation and therefore cannot fully adjust their body temperature under different environmental conditions.

For years several clinical studies worldwide have been concerned with temperature control issues and the fact that cooling systems have proven to be beneficial in their various forms. Davis et al. mentioned that "increased ambient or core body temperature" worsens clinical signs of MS patients while Song et al. highlighted that SCI patients "cannot appropriately respond to the changing temperatures of their surrounding environments". The JAY J3 TC was specifically designed to help reduce some of these most common symptoms.
