Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
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.
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.
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.
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.
tDCS sham and EAC
Subjects will receive 05 sessions of tDCS sham and EAC.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 consist of electrical stimulation with a frequency of 2 Hz for 30 min. The needles are placed beside the spinous processes of L1 to S2, with a depth of 3 cm and in the muscles: vastus lateralis, rectus anterioris, vastus medialis, tibialis anterior, peroneus longus and insertion of the pes anserinus.
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.
tDCS and EAC
Subjects will receive 05 sessions of transcranial direct current stimulation(tDCS) and electroacupuncture(EAC). 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. The electroacupuncture consist of electrical stimulation with a frequency of 2 Hz for 30 min. The needles are placed beside the spinous processes of L1 to S2, with a depth of 3 cm and in the muscles: vastus lateralis, rectus anterioris, vastus medialis, tibialis anterior, peroneus longus and insertion of the pes anserinus.
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.
