17 sierpnia 2017 zaktualizowane przez: Hospital de Clinicas de Porto Alegre
Effect of Transcranial Direct Current Stimulation and Electro Acupuncture in Pain, Functional Capability and Cortical Excitability in Patients With Osteoarthritis.
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.

Szczegółowy opis
The knee osteoarthritis has high prevalence, which tends to increase with the aging population.
The limited efficacy of pharmacological interventions stimulates the search for other options, in order to increase the therapeutic success.
Acupuncture is widely used for pain control in several pathologies.
A modality of intramuscular stimulation to quantify the intensity of the stimulus is electro acupuncture (EAC) that the intensity of 2 Hz accelerates the release of enkephalins, endorphins and beta-endorphins.
The application of electric currents to modify brain function is a very old technique.
The transcranial direct current stimulation (tDCS) is based on applying transcranial direct weak current (usually above 2mA) through electrodes in a non-invasive, simple and painless.
Other advantages include low cost and the possibility of a placebo reliable.
The purpose of this study is to evaluate the ability to reduce pain and improve functionality in chronic pain for knee osteoarthritis with two techniques, one that promotes a bottom-up approach (EAC) and other top-down (tDCS).
We will seek to analyze the efficacy of them separately and together, seeking summation of results.

Aktywny komparator: tDCS and EAC sham
Subjects will receive 05 sessions of tDCS.
The tDCS consist of application of current of 2 mA, the anode being placed in the motor cortex (M1) and the cathode in the supraorbital region, for 30 minutes,using electrodes with saline solution.
The sham DIMST consist of the use of rubber electrodes placed in the same places that active treatment.
Will use the same electrical apparatus, but without pass of current to the electrodes.
The unit will be in front of the patient on with their lights blinking.
|
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.

Komparator placebo: tDCS sham and EAC sham
The subjects will receive 05 sessions of tDCS sham and EAC sham.
The sham tDCS be performed in the same way as the active, although the Electro device is turned off 30 seconds after the beginning of treatment, the session will have the same duration of 30 minutes.
The EAC sham consists of placement of rubber electrodes in the same areas of active stimulation (beside the spinous processes of L1 to S2, muscles vastus lateralis, rectus anterioris, vastus medialis, tibialis anterior, peroneus longus and insertion of the pes anserinus).
The electrodes are connected to the same device electro, for 30 minutes, but without passage of electrical stimulation to the patient.
The device is kept on and in front of the patient, with the lights blinking.
|
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.

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.
