      <study_design>Randomization: Randomized, Blinding: Triple blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: The balanced randomization using the covariate adaptive randomization technique described by Taves. First, We will assign a number of participants in each group using sequentially numbered, opaque, sealed envelopes. Then, the Taves method will be used to balance participants in the groups based on the important covariates such as sex and age, Blinding description: The data analyst and the outcome assessor will be blinded to group allocation of each participant.Participants will not be aware of their group allocation ( there is 3 experiment group).</study_design>

      <i_freetext>Intervention 1: The intervention group 1: In this group, participants will receive 10 sessions of real cerebral and peripheral electrical stimulation,   5 days a week, for two weeks. The cerebral stimulation will be applied using a transcranial direct current stimulation (2 mA, energy density of 0.057 mA per square centimeter).  The peripheral electrical stimulation will be applied using a Transcutaneous electrical nerve stimulation apparatus  (100 Hz frequency, a pulse duration of 200 μs, asymmetrical biphasic square wave). TENS current intensity will be regulated according to the patient sensory threshold, characterized as an intense, yet comfortable. In each treatment session, patients will receive 20 min cerebral electrical stimulation, and 30 min peripheral electrical stimulation. Intervention 2: The intervention group 2: Participants will receive real cerebral and sham peripheral stimulation. For sham peripheral stimulation, TENS adjustment will be similar to the group 1. But in this group, 30 sec after adjustment of the intensity of stimulation, the TENS machine will be switched off. Intervention 3: The intervention group 3: Participants will receive sham cerebral and real peripheral stimulation. For sham cerebral stimulation, the cerebral stimulation set up will be similar to the other groups. But after 30 sec the tDCS machine will be switched off.</i_freetext>

      <results_IPD_description>What will be shared:
one year after publication, all of participants data (without identifiers) collected during the trial will be shared 

The study's protocol will be submitted for publication in an international journal, following registration of the trial in IRCT. The study's protocol will contain statistical analysis plan. 

We plan to inform Health Care Professionals of our findings by submitting our results for publication in international scientific journals. Furthermore, the results of our research will be shared with researchers at national and international scientific meetings and conferences.

When:
One year after publication

To whom:
Researchers and health professionals

Conditions:
Research and clinical use.

Where to obtain:
Secure scientific websites and the researchers of the study
Scientific website Journals, and search engines such Google Scholars, Research gate, and Pubmed

How to obtain:
Online access via scientific websites or email to the investigators
