TONEFITreha: Proof of Concept and Usability Study.

The newly developed Tonefit Reha is based on the existing fitness device, the TONEFIT belt. Similar to Nordic Walking, the device aims to include upper limb activity in walking exercise to train the shoulder girdle and arm. While Nordic Walking uses poles, the existing TONEFIT belt uses body-worn resistance handles to actively involve the upper body. It is worn around the waist, like a belt. The two independent pull-push elements with non-adjustable resistance on each side allow increased intensity for strengthening and endurance training during walking, particular for upper extremities and trunk stability.
