Robotic prosthetic ankle improves ‘natural’ limb movement

Researchers have developed a robotic prosthetic ankle that boosts the postural control of the wearer and stability of the lower limb. The prosthesis was controlled using electromyographic (EMG) signals, which are the electrical signals recorded from an individual’s muscles.

They developed their model on a previous study, in which the team had demonstrated that the device responded to electrical signals from a patient’s muscles using neural control technologies and helped them to move more naturally and intuitively. The team observed that the patients were able to perform a wide range of…
