Does Electroacupuncture Treatment Reduce Pain and Change Quantitative Sensory Testing Responses in Patients with Chronic Nonspecific Low Back Pain? A Randomized Controlled Clinical Trial.

Chronic nonspecific low back pain is common and one of the most disabling conditions in the world. There is moderate evidence that chronic low back pain patients present altered functional connectivity in areas related to pain processing. Quantitative sensory testing is a way of clinical measure of these alterations.

Does electrode placement influence tens-induced antihyperalgesia in experimental inflammatory pain model?

Background: Transcutaneous electrical nerve stimulation (TENS) is a treatment commonly used for managing pain; however, the ideal placement of the electrodes is not fully understood.

Objective: To investigate the best way to apply TENS electrodes in an experimental inflammatory pain model.

Method: Knee joint inflammation was induced in rats, followed by administration of low-frequency TENS (4Hz) under anesthesia for five days.
