Sensors that make sense of walking in artificial legs

Switzerland: People with leg disabilities can walk with the help of prosthetic legs, but they do not feel the need to step on the ground and set foot, which causes a lot of problems, but now with special sensors, they feel the need to step. Are.

The Swiss Federal Institute of Technology scientist in Switzerland, Dr. Stenisa Rispo Povch and colleagues applied sensors to the foot and ankle of two men's prosthetic legs, and the strands were attached to the thigh nerve. Is.

Later, when the sensors were tested on those who lost their legs, both men said that they can now walk very confidently and fast. Individuals with leg dislocations up to the knees cannot feel their leg position and have difficulty walking.

It should be noted that people with arms and legs suffer from a mysterious condition for a period of time in which they sometimes feel their broken hands and feet and they also feel discomfort. This disease is also called phantom lump. People also noticed this decrease after applying the sensor.

When both men were tested for a month by applying sensors to their thigh nerves, they described it as astonishing and said that they now feel like real legs because of the sensor. Experts then put sensors on the prosthetic legs of the missing persons, and tested them outside the laboratory.

After sensing the sensation, both men felt very comfortable and confident in walking. At first they could walk six meters a minute, but after being sensed, they were able to walk just like healthy humans and their speed increased. One person said that the prosthetic leg now looks like a real leg.

Similarly, in three months, the condition of Phantom Lamp in people with disabilities was 80%.
