About this study
Official title: Effectiveness of Transcranial Direct Current Stimulation on Functionality and Pain in Individuals With Patellar Tendinopathy: Randomized Clinical Trial
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.
Read the detailed description
Patellar tendinopathy is a painful condition affecting the anterior portion of the knee, commonly exacerbated by activities putting pressure on the patellofemoral joint. It remains a challenge for the healthcare system, not only due to its high prevalence, but also because of its high persistence and negative consequences. Although therapeutic exercise has been widely studied as a treatment strategy, eccentric exercise protocols, while effective, often require long application periods, which may affect treatment adherence. Additionally, eccentric exercise is pain-provoking and its therapeutic benefits for pain relief and functional improvement are controversial when used during the competitive season. More adaptable and personalized treatment strategies could enhance clinical outcomes and treatment adherence in patients with patellar tendinopathy. In this context, interventions combining exercise with other techniques have been proposed. However, existing evidence does not definitively determine the optimal approach for combining conservative treatment options to maximize benefits.
An emerging therapeutic approach combines Transcranial Direct Current Stimulation (tDCS) with therapeutic exercise protocols. tDCS involves the application of weak direct current to specific cortical areas, aiming to modulate brain excitability. This non-invasive method offers painless, selective, and focal stimulation with minimal side effects. Research increasingly supports the effectiveness of integrating tDCS with exercise for patellar tendinopathy, offering the potential to amplify exercise effects by modulating brain excitability. However, to date, no study has investigated the impact of tDCS combined with eccentric exercise on variables related to function and pain in patellar tendinopathy individuals.
Therefore, the aim of this study is to investigate the effectiveness of tDCS prior to a therapeutic eccentric exercise program on parameters related to pain and functionality in individuals with patellar tendinopathy.
This study is a randomized clinical trial in which two groups will participate, with different interventions: i) Experimental group: tDCS + Therapeutic eccentric exercise; and ii) Control group: Sham tDCS + Therapeutic eccentric exercise. The interventions will last for 8 weeks. Participants will be evaluated in four moments, at baseline, week 4, week 8 and week 12. The variables studied are related to pain, functionality, muscle strength and activity, proprioception, and quality of life.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
tDCS + Therapeutic eccentric exerciseOther
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 exerciseOther
The current will be interrupted after 30 seconds.
| Study group | Role | What they receive |
|---|---|---|
| Experimental group | Experimental | Participants will undergo an 8-week intervention of supervised eccentric exercise by a physiotherapist (3 sessions/week). During the first 4 weeks, real tDCS will be administered at a rate of 3 sessions per week (12 in total) as an adjunct to 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Knee functionality
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.
Measured: 5 minutes
Secondary outcomes (8)
Pain intensity
The single-leg squat pain provocation test is used to monitor the response to previous loading in athletes with patella tendinopathy. A visual analogue scale (VAS) will be used to determine pain intensity during the test. A score of 0 points indicates no pain and 10 points is the worst imaginable pain.
Measured: 2 minutes
Health-related quality of life
The EuroQol 5 dimensions (EQ-5D) test is an instrument which evaluates the generic quality of life. Scores range from 0 (worst imaginable health state) to 100 (best imaginable health state).
Measured: 2 minutes
Muscle strength
Maximum voluntary isometric contraction of the quadriceps, hamstrings, and hip abductors will be measured using a force sensor connected to the corresponding software (Chronojump Boscosystem). Higher values indicate greater muscle strength.
Measured: 10 minutes
Electromyographic activity of lower limb muscles
Electromyographic activity during maximum voluntary isometric contraction of the rectus femoris, vastus lateralis, vastus medialis, biceps femoris, and semitendinosus muscles, using electromyography, will be registered.
Measured: 5 minutes
Muscle flexibility
Knee joint range of motion will be measured in flexion and extension using a goniometer. Higher values indicate greater muscle flexibility.
Measured: 5 minutes
Muscle tone
The biomechanical and viscoelastic properties of the muscle tissue will be evaluated using a non-invasive myometer, MyotonPRO (Myoton AS, Tallinn, Estonia). The patellar tendon, rectus femoris, vastus medialis, vastus lateralis, semitendinosus, and biceps femoris will be assessed. Higher values may indicate greater muscle stiffness or tone.
Measured: 5 minutes
Proprioception
Proprioception will be assessed using the active knee repositioning test with an inclinometer. The difference between the target angle and the obtained angle will be registered. A smaller difference between the angles indicates better knee proprioception.
Measured: 5 minutes
Patient global perception of change
The Patient Global Impression of Change Scale (PGIC) will be filled out. It consists of 7 points, with options ranging from "1=much better" to "7=much worse".
Measured: 1 minute

Questions about this trial
What is this clinical trial studying?
A study testing tDCS + Therapeutic eccentric exercise in people with Patellar Tendinopathy, run by University of Valencia at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 25 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
