Peripheral nerve stimulation via multi-contact nerve cuff electrodes (NCEs) has proved effective in restoring function to individuals with lower-extremity paralysis. This study investigates clinical measures of nerve health over one year post-implantation of a composite flat-interface nerve electrode (C-FINE) on the tibial and peroneal nerves above the knee in a human volunteer. This represents the first deployment of a novel NCE on new neural targets in a uniquely challenging location prone to prolonged externally applied forces, making acute and chronic postoperative observation critical. ⋯ Above-knee tibial and peroneal NCEs can restore stimulated ankle-joint function without chronic nerve health detriments. Alongside previous femoral nerve data, this study demonstrates the ability of NCEs to enhance lower-extremity function with limited neuromuscular impact.

Ocular pain is a debilitating condition that is challenging to treat as therapies that target the ocular surface are often ineffective. We previously reported a short-term reduction in ocular pain after one periocular transcutaneous electrical nerve stimulation (TENS) session. The current study aims to elucidate the long-term effect of TENS on ocular pain. ⋯ Our preliminary data suggest that TENS can be integrated into the long-term management of ocular pain with improvements in overall pain intensity.

High demand of flexor hallucis longus (FHL) in the positions of extreme flexion of the ankle and toes is required in the dance. The aim was to investigate the effects of single-shot of ultrasound-guided percutaneous neuromodulation (PNM) vs. single-shot of transcutaneous electrical nerve stimulation (TENS) in performance of the FHL muscle in professional dancers. ⋯ Simple single-shot procedure with percutaneous or TENS provided immediate performance improvement of FHL muscle in dancers, being PNM the more effective intervention.

Axillary Peripheral Nerve Stimulation for Chronic Shoulder Pain: A Retrospective Case Series.
The objective of this study was to determine the effect of axillary peripheral nerve stimulation (PNS) on pain reduction in patients with chronic shoulder pain. Chronic shoulder pain was defined as pain greater than six months originating from any of the following and not the result of a stroke: subacromial impingement syndrome/rotator cuff pathology, glenohumeral joint arthritis, acromioclavicular joint arthritis, adhesive capsulitis, or biceps tendinopathy. ⋯ This retrospective case series provides level IV evidence supporting the use of axillary PNS therapy for the management of chronic shoulder pain. Additional, higher-level studies are required to further support its use.
