Background. Spinal cord stimulation (SCS) is being used with increasing frequency in the treatment of various chronic pain conditions. There is a paucity of reliable outcome data regarding changes in pain tolerance and peripheral sensory nerve function. ⋯ The results of this study appear to substantiate the postulates that both segmental and suprasegmental effects are involved in SCS-mediated analgesia. SCS modulates segmental large afferent fiber input as reflected by a statistically significant increase in large fiber CPTs (2000 Hz) at the symptomatic site post-SCS. A statistically significant increase in small fiber (5 Hz) CPTs at the control site suggests a central sensory (suprasegmental) modulating effect on nociceptive fiber activity. sNCT testing provided reliable outcome data for evaluating response to SCS.

Objective. The aim of the paper is to present various relatively simple functional electrical stimulation (FES) systems that affect neural circuits and reflex behavior by providing necessary peripheral input to the lower extremities of incomplete spinal cord injured (SCI) persons. Methods. ⋯ The information about several gait variables can be first integrated and afterwards delivered to the walking subject as a single command. Conclusions. Significant improvements in the duration of the double support phase, metabolic energy expenditure, and physiologic cost index were observed when using FES-assisted training of walking in incomplete SCI persons.

Objectives. To investigate the feasibility of inhibiting the stretch reflex of the soleus muscle by a conditioning stimulus applied to the deep peroneal nerve in spastic stroke participants during the early swing phase of gait. Materials and Methods. ⋯ Conclusions. It is concluded that the inhibition of the soleus stretch reflex with an electrical conditioning stimulus applied to the deep peroneal nerve is feasible in the early swing phase of walking. This shows a potential for being used in the rehabilitation of walking by spastic stroke persons.

Objective. This one-year pilot outcome study was designed to investigate prospectively a series of patients with chronic discogenic back pain who underwent intradiscal electrothermal annuloplasty (IDET). Patients with chronic discogenic low back pain usually respond poorly to conservative medical care. ⋯ There were no significant complications. Conclusions. One-year pilot study outcome results suggest that IDET may be an effective, minimally invasive treatment for chronic discogenic low back pain.
