Objective. Sensory feedback extracted from muscle afferents is an approach to achieve closed-loop control of paralyzed muscles using functional electrical stimulation (FES). The objective of the present study was to characterize the effect of agonist-antagonist electrical stimulation on nerve cuff recordings of muscle afferent activity. ⋯ It was suggested that the increased background activity could be attributed to the increased activity of the Golgi tendon organs. Conclusions. Sensory information about joint flexion and joint extension are preserved in muscle afferent recordings from electrically activated muscles at low and intermediate stimulation levels, but it still has to be shown whether muscle afferent information can be useful as sensory feedback in FES control.

Objective. To present a novel treatment approach for intractable inguinal neuralgia utilizing percutaneous peripheral electrostimulation. Materials and Methods. ⋯ Both patients who were on disability due to inguinal pain have been able to return to full-time employment. Conclusion. These preliminary results suggest that the technique described is effective and safe, and may be cost-effective as well.
