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)
* pain relief slower than intra-articular glucocorticoid
Contraindications
- not useful for lateral epicondylitis[1]
- should not be used near cardiac pacemaker (i.e. TENS for shoulder)
Procedure
- 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]
