Hand(some) prosthetic technology

Neuroprosthetic devices providing tactile feedback sensation have been recently developed. Electrodes stimulating peripheral nerves have been shown to provide patients with the sense of touch and pressure when using upper limb prosthesis. Moreover, targeted muscle innervation can provide prosthesis control. However, the number of independent movements is still limited. Now, Vu et al. showed that regenerative peripheral nerve interfaces (RPNIs) implanted in upper limb amputees allowed the control of finger movements using hand prosthesis for almost a year without the need for adjustments. The results suggest that RNPIs could provide a stable and improved upper limb prosthesis control.
