Summary

The objective of this study is to evaluate the efficacy of transcranial direct current stimulation (tDCS) and electro acupuncture (EAC) compared to sham treatment in reducing pain, improving functional capacity and functioning of the neuro-immune-endocrine system in patients with chronic pain due to knee osteoarthritis.

Conditions

Interventions

OTHER

tDCS and EAC sham

The tDCS apparatus is operated on battery power, will be used rubber electrodes soaked in saline solution. The anode is placed in M1 and the cathode in the supraorbital region.

OTHER

tDCS sham and EAC sham

For the EAC sham we will use rubber electrodes. They will be applied in the same areas of active EAC. They are connected to the same electroacupuncture device, but without current passing for the patient. All subjects receive one 30min session.

OTHER

tDCS sham and EAC

For the sham tDCS we will use the same apparatus in the same location, but the current is stopped after 30 seconds.

OTHER

tDCS and EAC

For the acupuncture we will use needles with guide tubes that are 40 mm in length and 0.25 mm in diameter. The needling will be applied using an electro acupuncture device in the dermatomes, myotome, or sclerotome corresponding to the nerve roots involved in the knee (L1, L2, L3, L4, L5, S1, and S2). All patients received one 30min session using a frequency of 2 Hz.
