Amputees cannot feel slopes or holes and continuously risk falling as well as feel phantom limb pain. The reason – current prostheses that replace lower limb amputations do not relay sensory feedback.
There is an estimated 3.18 million people in the EU with lower limb amputations and about 295 000 amputations are performed annually. Currently used prostheses do not have sensory feedback resulting in amputees having lack of confidence in the prosthesis and reduced mobility. Patients may even abandon use of the prosthesis altogether, and at best, reduce their activity levels in everyday tasks dramatically.
