Feasibility of an Analgesic Device Enabling Local Anesthetic Delivery and Neuromodulation After Shoulder/Foot Surgery

Percutaneous peripheral nerve stimulation with a frequency between 1-250 Hz, a pulse duration of 1-200 µs, and a current of 0.001-10 mA (1-10,000 µA). If the same pattern holds for the RELAY device as for previously tested peripheral nerve stimulators, we will maximize frequency, minimize pulse duration, and have participants adjust the amplitude, as needed.
