Non-invasive brain neuromodulation

Transcranial Direct Current Stimulation (TDCS)

TDCS is a non-invasive and painless neuromodulation technique that applies a very low-intensity direct current to specific scalp areas to modulate brain activity. It helps adjust cortical excitability — increasing or decreasing it as needed — to improve pain processing, motor control and cognitive-emotional balance. The procedure is quick, precise and well tolerated.

What it is and how it works

We place soft electrodes on specific scalp regions according to the cortical areas we want to influence. A gentle galvanic current flows for about 20–30 minutes, shifting the membrane potential of cortical neurons. Depending on polarity, stimulation can increase (anodal) or decrease (cathodal) excitability.
tDCS promotes neuroplasticity — the brain’s ability to reorganise and form new connections — and often enhances the effect of physiotherapy, percutaneous techniques and therapeutic exercise performed in the same plan.
Parameters (electrode montage, intensity and duration) are based on scientific evidence and tailored to your presentation. The technique is non-invasive, painless and allows you to relax during the session.

Good to know: You may feel a light tingling or warmth under the electrodes during the first seconds — it fades quickly and is normal.

Therapeutic effects

Pain modulation

Improves pain processing and reduces central sensitisation.

Can help decrease medication needs in chronic conditions.

Supports calmer, more comfortable movement.

Motor function

Facilitates motor cortex excitability when needed.

Improves coordination and motor learning.

Pairs with task-specific training for best results.

Neuroplasticity boost

Primes the brain to respond better to rehab.

Enhances the effects of EPTE/PNM/exercise.

Contributes to faster, more durable recovery.

Clinical indications

Chronic pain

Chronic pain.

Fibromyalgia and widespread pain.

Migraines and tension-type headaches.

Neurological rehab

Motor recovery after stroke.

Parkinson’s disease (adjunct).

Neurocognitive & mood

Depression and anxiety (adjunct).

Addictions and attention deficit (ADHD).

Safety & contraindications

tDCS is very safe when used by trained professionals. Possible minor effects include slight itching or redness under the electrodes — they resolve quickly.
We avoid or adapt in cases such as uncontrolled epilepsy, metal implants in the head, open scalp wounds, implanted electronic devices, pregnancy (as precaution), or when you prefer a non-stimulation approach. We assess every case individually.

What a session looks like

Assessment & plan. We define goals and select the cortical targets and montage.

Electrode placement. We prepare the skin and place comfortable electrodes precisely.

Stimulation. 20–30 minutes of gentle current while you relax; you may chat or rest.

Integration. We combine tDCS with movement or targeted tasks to consolidate the effect.

TDCS — FAQs

Answers to common questions about non-invasive transcranial direct current stimulation at Weheal.

What is tDCS and how does it work?

tDCS is a non-invasive, painless technique that uses very low-intensity direct current delivered through scalp electrodes to modulate brain activity. Depending on the montage and polarity, it can increase or decrease cortical excitability to support pain relief, motor control and emotional regulation.

What are the main benefits of tDCS?

It can reduce pain, enhance motor learning and promote neuroplasticity. It often helps decrease medication needs in chronic conditions and accelerates recovery when combined with exercise therapy, percutaneous techniques and manual therapy.

Is the treatment painful?

No. Most patients notice only a light tingling or warmth under the electrodes at the start — it fades quickly. Sessions are calm and well tolerated.

How many sessions are usually needed?

It depends on your goals and condition, but many people improve after 5–10 sessions, typically 2–3 per week. Each session lasts about 20–30 minutes, and effects are cumulative.

Can tDCS be combined with other physiotherapy techniques?

Absolutely. We often use it to prime the nervous system so that exercise therapy, percutaneous neuromodulation or electrolysis — and education — have a greater, more durable impact.

What conditions can be treated with tDCS?

Chronic pain, fibromyalgia, migraines; motor recovery after stroke; Parkinson’s disease (adjunct); depression, anxiety and addictions; and attention deficit (ADHD), among others — always after individual assessment.

Are there any contraindications or side effects?

tDCS is very safe; minor effects like temporary redness or itching may appear under electrodes. We avoid or adapt in uncontrolled epilepsy, head metal implants, open scalp wounds, implanted electronic devices, pregnancy (as precaution) and similar cases.

How soon can I return to normal activity after a session?

Immediately — there’s no downtime. Many patients resume their day feeling calmer, with reduced pain perception or clearer focus, which helps rehabilitation tasks.

Is tDCS right for your case?

Tell us about your situation and we’ll guide you clearly. If tDCS adds value, we’ll integrate it with movement and education so benefits translate to daily life and sport
