Mediroyal TONUS® is a new dynamic splint for tonus reduction for patients with spasticity. It combines a rigid frame that can be adjusted individually to the patient in combination with an inflatable air bladder, which provides both individual support to the MCParch as well as dynamic finger and wrist extension.

The Mediroyal TONUS™ splint provides a unique treatment option with both stabilizing flexion of the wrist as well as providing dynamic extension to the wrist- and fingers in combination with supporting the MCP-arch. Patients with spasticity usually end up in a flexion pattern over the wrist and fingers that can further trigger spasticity. In order to reduce spasticity it’s important to stabilize the wrist flexion and at the same time provide support over the MCP-arch to open the fingers and to provide constant and even stretch over the flexor tendons. This is an effective way to reduce tonus on the patient and to reach a long-term stretch that aims to make the stretch reflex in the muscle spool less hyper sensitive.

The recommendation is to use the splint in intervals of 1-2 hours at a time, two to three times daily for at least 3-6 months.

The TONUS™ material has been specially developed to provide both a good ventilation, humidity control and pressure absorption. Neurological patient have a very sensitive skin. Moisture in combination with pressure can effectively cause skin breakdown. We spent almost 2 years to develop the new material, that combine specially treated ecological wool from Norway and New Zealand and a hollow PES fiber that enhances moisture transportation from the skin surface. The wool is excellent to regulate temperature and transport moisture. The new TONUS™ material is machine washable at 60 degrees Celsius to maintain a good hygienic condition on the patient. All the splints come with a special laundry bag that has been developed for the cover.

TON406 TONUS® RG model has a rotation adapter built in to adjust ulnar- and radial deviation. This provides an opportunity to more specific extension stretch over affected flexor tendons and to compensate for ulnar or radial deviation. The adapter can be adjusted individually and then secured in place with the screw driver included.
