Abstract
This study examines the use of muscle activity and nerve stimulation for trans-tibial prosthetic control. We tested various modes of an osseointegrated prosthesis – in a cat subject – that varied in their implementation of control using soleus EMG activity as well as residual nerve stimulation to see if these factors would improve locomotor biomechanics in level and sloped walking. The results indicate that there were varying effects of EMG-based control and nerve stimulation on locomotor variables. It was found that the prosthesis was able to reduce asymmetry of locomotion, but there were still compensations from remaining portions of the ipsilateral limb. The EMG-based prosthetic control with communication of sensory motion-dependent information from the prosthesis still requires further studying and adjustment but show promise in improving locomotion.
