tDCS + Therapeutic eccentric exercise: A direct current of 1.5 mA will be applied for 20 minutes to the primary motor cortex (M1) during each session of eccentric exercises.
Sham tDCS + Therapeutic eccentric exercise: The current will be interrupted after 30 seconds.
Study summary
The aim of the present study is to investigate the effectiveness of transcranial direct current stimulation (tDCS) prior to a therapeutic eccentric exercise program on parameters related to pain and functionality in individuals with patellar tendinopathy. For this purpose, participants will be randomly divided into two groups: i) experimental group, receiving tDCS prior to a therapeutic exercise program; and ii) control group, receiving sham tDCS and a therapeutic exercise program. The interventions will last for 8 weeks. Additionally, four assessments will be conducted (baseline, week 4, week 8 and week 12). The variables studied are related to pain, functionality, muscle activity and strength, proprioception, and quality of life.

Primary outcome measure(s)
Knee functionality — 5 minutes The Victorian Institute of Sport Assessment-Patella (VISA-P) is a questionnaire to assess the severity of patellar tendinopathies. It consists of 8 items with a rating range from 0 to 100. The optimal state would correspond to a score of 100.
