transcutaneous electrical nerve stimulation (TENS, Stimpod NMS460)

^[1]^[2]^[3]

Indications

relief of chronic pain
- neurogenic pain
- functional abdominal pain in patients 11-18 years of age with irritable bowel syndrome (IB-Stim)^[3]
total hip arthroplasty (transcutaneous electrical acupoint stimulation)

a small battery-operated device, worn by the patient, which provides continuous electrical pulses via surface electrodes applied to the skin with the goal of providing symptomatic relief by modifying pain perception (electroanalgesia)
Stimpod NMS460 applies pulsed radiofrequency waveform to the affected area transcutaneously^[2]
IB-Stim^[3]
- prescription-only device
- consist of a small single-use electrical nerve stimulator placed behind the patient's ear
- device contains a battery-powered chip that emits low-frequency electrical pulses to stimulate branches of cranial nerves continuously for 5 days
- device is replaced after 5 days
- stimulating nerve bundles in & around the ear is thought to provide pain relief
- patients can use the device for up to 3 consecutive weeks to reduce functional abdominal pain associated with IBS^[3]
