COGY Profhand PH1608 – Medium

COGY Profhand™ : is the World's most Innovative Pedal Wheelchair.

Combining state of the art Japanese industrial design and engineering, the COGY Profhand pedal wheelchair was developed by Professor Yasunobu Handa and his research team from Tohoku University Graduate School of Medicine, Japan. In applying the Neuromodulation Technique (NMT) with enormous efforts and time dedicated, the team has undergone numerous researches and testing throughout the product development process which yields encouraging results. The pedal wheelchair is proven to be a highly effective and reliable partner for user mobility and rehabilitation since its launch in 2009. COGY Profhand has CE and FDA approval.

COGY Profhand ingenious pedaling system and single-arm steering was is designed for individuals experiencing walking disabilities and paralysis on one side of the body which may result from stroke, spinal injuries, cerebral palsy, hip joint or lower back pain due to degenerative diseases, osteoarthritis, knee deformity, Parkinson’s disease, chronic obstructive pulmonary disease, obstructive atherosclerosis, diabetes and other. Its design enables the affected leg to be exercised and strengthened while being supported by the stronger leg. Profhand therapeutic function, helps to potential benefit in the overall Cardio-Respiratory capacity (blood circulation and breathing), strengthen weak or passive muscles, increase muscle activity, and engaging multiple body systems with synergy. In addition to the physiological therapeutic gain, COGY Profhand fosters positive rehabilitation and yields therapeutic benefit in confidence and independence, vitality, feeling of freedom and regained mobility, as well as lessened need for less close caregiver assistance.


Therapeutic alteration Neuromodulation ? encompasses a variable definition in both its entity and activity. It can include treatments that involve the stimulation of various nerves in the central nervous system, peripheral nervous system, autonomic nervous system, or deep cell nuclei of the brain that lead to the ‘modulation’ of its activity. By definition, Neuromodulation is a therapeutic alteration of activity either through stimulation or medication, both of which are introduced by implanted devices. However, COGY Profhand pedal wheelchair based on this technology does not rely on any surgery and medication; it optimizes the use of the body in the process of rehabilitation.

Central Pattern Generator

The key feature of COGY Profhand pedal wheelchair is that it enables users to move their weak or even paralyzed legs. According to Professor Yasunobu Handa of Tohoku University, Japan, this is caused by the response actually appears in the Central Pattern Generator (CPG) ? within the spinal cord producing rhythmic movements. In case of an individual with either side paralyzed who pedals COGY Profhand wheelchair, the Central Pattern Generator (CPG) in the spinal cord generates the signals of walking instruction to the disabled leg by getting reflex signal from the normal leg. Disabled leg thus moves like as normal without any consciousness from the brain.

  2. Neural networks in the spinal cord, referred to as “central pattern generators” (CPGs), are capable of producing rhythmic movements, such as swimming, walking, and hopping, even when isolated from the brain and sensory inputs
