描述
We will enroll 84 women that being starts a chemotherapy protocol with a Anthracycline and Cyclophosphamide (AC) as a part of breast cancer treatment. All volunteers will be submitted a 30 minutes TENS prior to chemotherapy administration. Three different TENS treatment will be test: 1) placebo; 2) high frequency and 3) low frequency. The self-adhesive electrodes will be positioned in the same position for all different TENS treatment (opposite arm to the chemotherapy infusion). The eletctrodes will be positioned as follows: the first electrode at the PC6 point which is located proximal to the flexion fold of the wrist in the middle of the anterior face of the forearm, between the tendons of the long palmar and radial flexor muscles of the carpus and the second electrode at any point in the hand. After that, all volunteers will receipt a formulary to self-complete a nausea and vomit symptoms record during the next 24 hours. Number of incidence and magnitude of the symptoms will express the accumulated indices the occurrence and severity of the symptoms, as further describe in this protocol.

Placebo Comparator: Placebo Group Placebo Group: In this group the participants received TENS with frequency of 75Hz, pulse duration of 200 microseconds. The stimulation time will be for only 10s. | Device: Placebo Group In this group, the TENS will be administered by 30 minutes prior to chemotherapy administration with the stander electrodes positions, in the opposite arm of the chemotherapy infusion, but in this group the electrical stimulation will be performed just by 10 seconds and turn off for all reminiscent time of the protocol. |
Experimental: Low Frequency Group Low Frequency Group: In this group the TENS will be adjusted with frequency of 10Hz, pulse duration of 200 microseconds. The stimulation time will be 30 minutes and the intensity will be constantly adjusted in order to keep as high as possible within the tolerance threshold of the patient. | Device: Low Frequency Group In this group the TENS will be administered by 30 minutes prior to chemotherapy administration with the stander electrodes positions, in the arm opposite the chemotherapy infusion. The electrical stimulation will be continued for all time secession. The electrical pulse parameters will be setting according describe early. |
Experimental: High Frequency Group High Frequency Group: In this group the TENS will be adjusted with frequency of 150Hz, pulse duration of 200 microseconds. The stimulation time will be 30 minutes and the intensity will be constantly adjusted in order to keep as high as possible within the tolerance threshold of the patient. | Device: High Frequency Group In this group the TENS will be administered by 30 minutes prior to chemotherapy administration with the stander electrodes positions, in the arm opposite the chemotherapy infusion. The electrical stimulation will be continued for all time secession. The electrical pulse parameters will be setting according describe early. |
