Background: Transcranial direct current stimulation (tDCS) triggers brain activity by altering the membrane potential and the synaptic release, thereby aiding in neuroplastic trigger altering. tDCS is widely used to improve motor function in healthy people and neurological patients. This study reviewed the effect of tDCS modality on proprioception in patients with tendinopathy.
Methods: This study mainly evaluated four databases that include PubMed, Scopus, Web of Science, and the first 10 pages of Google Scholar for English clinical articles that studied the effect of tDCS on proprioception. The keywords used in the search included: transcranial direct current stimulation, sense of position, sense of force, sense of effort, tendinitis, tendinopathy, goniometer, electromyography, tendon, muscle force, proprioception, and load cell.
Results: The search yielded nine published articles of the required clinical prospective studies (total participants=199) were obtained. We used the PRISMA checklist for the selected articles.
Conclusion: tDCS can have a positive role in the improvement of proprioception and balance ability. The absolute error of proprioception is predominantly notable in the elbows compared to the other joints.
