In general, to study the neuromodulation, it is often use the electrical simulation to help the recovery of nerve; however, the pedal wheelchairs do not use the electrical simulation at all.

The main feature of the pedal wheelchairs is that they enable patients to move their paralyzed legs. The patients have suffered from strokes that damaged parts of their brains, leaving half of their bodies paralyzed. Just as the healthy people can run without consciously thinking about it, using the pedal wheelchairs activate similar mechanism in the patients' bodies, enabling them to pedal with both legs.

Why a paralyzed leg can move again?

Although it has not been able to explain the details in the medical science at this moment, this can be predictable. According to a research, this is caused by the response actually appears in the central pattern generator within the spinal cord.

Normally when the healthy people walk, it is the brain to release the walking instruction to the legs. But during cycling the pedal wheelchair by a half paralyzed person (for example, left side paralyzed), the central pattern generator in the spinal cord generates the signal of the walking instruction to the right leg by getting reflex signal from the left leg, and vice versa.

The infants can do a lot of actions which are not instructed by the brain, but by the primitive reflex actions, for example, walking or stepping reflex, Palmar grasp reflex, Babinski reflex and sucking reflex. We believe that these reflexes are deeply related to the neuromodulation.

These pedal wheelchairs provoke the hidden potential ability of human being, and are tools regenerating the human natural born gift in reflex actions. They are not just transport equipment, but actually make the support of rehabilitation for paralyzed patients.

The pedaling does not only improve the motor functions in the patients' legs, but it also improves the central nerves in the spinal cord and the blood circulation in the brain and throughout the body, and the patients can even exercise their weakened legs to defer the degeneration. The patients regain more independence and freedom in their daily life.

As for the rehabilitation effect, although there are a lot of success patient cases, further scientific studies are now being done in the universities.

Neuromodulation is a new medical technology that does not rely on any surgery and medication. It makes sufficient use of the body in the process of rehabilitation.
