RehaBike offers people affected by paralysis a higher quality of life through physical exercise during an activity which is fun!

By means of Functional Electrical Stimulation (FES), muscles in the thigh are activated in such a way that coordinated movement is possible and sufficient power is generated.

This enables paralysed people to actively use their lower limbs again. As shown by research, this exercise boosts the metabolism and the cardiovascular system with many positive effects.

For many years scientists and engineers from the University of Glasgow, the Max Planck Institute in Magdeburg and the company HASOMED GmbH have been investigating the use of Functional Electrical Stimulation for neurological rehabilitation purposes.

Frequently, an accident or disease leads to the loss of a person’s ability to move their muscles. However, paralysed muscles can be made to contract by electrical impulses.  For applications of this kind, the RehaStim stimulator was developed which allows controlled movement of the legs or arms using Functional Electrical Stimulation (FES) technology.

The RehaBike consists of a specially equipped recumbent tricycle together with the RehaStim stimulator.

The user sitting on the tricycle is protected by seat-belts and purpose-built orthoses support the paralysed person’s legs.

Self-adhesive electrodes are fixed to the skin of the thighs and connected to the stimulator. The stimulator has a special program for cycling. The necessary parameters such as stimulation frequency and strength are easily adjusted. The individual parameters for each user can be saved.

At the push of a button cycling starts. The cyclist uses a “throttle” to control the stimulation intensity and thus the speed of the RehaBike. A sensor in the cranks continuously informs micro computers in the stimulator about the position of the cyclist’s legs. The micro computers calculate at what time each muscle needs to be stimulated and send the stimulation impulses to the electrodes on the legs. Thus they create a fluent pedalling movement.

Regular exercise of this kind improves the cyclist’s strength and endurance. RehaStim contains rechargeable batteries which allow independent cycling for several hours.

Reactivated and healthier 

Medical research shows that the activation of paralysed legs through Functional Electrical Stimulation boosts the metabolism and the cardiovascular system.

Risks such as arteriosclerosis, coronary heart disease and pressure sores can be reduced. The musculature rebuilds and the bone structure improves. The person affected by paralysis takes a more active part in life and gains new mobility.
