Direct skeletal attachment by osseointegration means:

 

• Improved range of motion since there are no physical boundaries by the socket – therefore the patient can move the remaining joints without restrictions

• There is an eradication of sores and pain caused by the constant pressure from the socket since this robot has no socket

• Stable and easy attachment/detachment

• Increased sensory feedback due to the direct transmission of forces and vibrations to the bone (osseoperception)

• The prosthesis can be worn all day, every day

• No socket adjustments required (there is no socket)
  
   

Implanting electrodes in nerves and muscles means that:

• Due to the intimate connection, the patients can control the robot with less effort and more precisely, and can then handle smaller and more delicate objects.

• The close proximity between source and electrode also prevents activity from other muscles from interfering (cross-talk), so that the patient can move the arm to any position and still maintain control of the prosthesis

• More movements can be controlled in the prosthesis

• After the first fitting of the controller, little or no recalibration is required because there is no need to reposition the electrodes on every occasion the prosthesis is worn (as opposed to superficial electrodes)

• Since the electrodes are implanted rather than placed over the skin, control is not affected by environmental conditions (cold and heat) that change the skin state, or by limb motions that displace the skin over the muscles.

• The control is also resilient to electromagnetic interference (noise form other electric devices or power lines) as the electrodes are protected by the body itself.

• Electrodes in the nerves can be used to send signals to the brain as sensations coming from the prostheses.
