This randomised controlled trial aims to compare the effect of microwave diathermy (continuous and pulsed modes) with sham microwave diathermy in nonspecific chronic neck pain patients. Every patient will also be treated by exercise and transcutaneous electrical neurostimulation (TENS). The primary endpoint is to establish whether the use of microwaves is justified in terms of pain relief or reduction of disability in this patients.
