TECAR Therapy for C-Section Scars: What Does the Evidence Say?

Recovering from a caesarean section takes time. Alongside caring for a newborn, you may be adjusting to changes in movement, abdominal strength and how the area around your scar feels.

Some people experience persistent tenderness, sensitivity or a pulling sensation after the wound has healed. These symptoms can raise questions about scar tissue therapy and whether treatments such as TECAR could help.

This article draws on published clinical research and NHS guidance. Research into TECAR for painful C-section scars is still developing, and its effectiveness for this specific purpose has not been established. Understanding that distinction helps you make an informed decision about treatment.

Importantly, this discussion concerns recovery after birth. It does not recommend TECAR treatment during pregnancy.

What Is TECAR Therapy?

TECAR therapy is a non-invasive treatment that uses radio frequency electrical energy delivered through electrodes applied to the body. Depending on the settings, it can produce warmth within the treated tissues.

Physiotherapists may use it alongside exercise, education and hands-on treatment as part of a rehabilitation programme.

The proposed effects on tissue temperature and circulation provide a reason to investigate its clinical use. However, a biological effect does not automatically establish that a treatment reduces scar pain, improves healing or leads to a faster recovery.

You can read more about the treatment on our TECAR therapy in London page.

Why Can a C-Section Scar Feel Tight or Sensitive?

A scar forms as part of the body’s natural repair process after surgery. Its appearance and sensation can change as it matures.

Some people notice tenderness, itching, altered sensation or tightness around the healed incision. NHS guidance recognises that some caesarean scars can feel sore or produce a pulling sensation. NHS guidance on caesarean scars.

However, discomfort around a C-section scar does not automatically mean that scar tissue is the cause. Persistent or worsening symptoms need assessment rather than an assumption that the scar simply needs treatment.

A useful assessment considers your symptoms, wound recovery, movement and medical history, including whether further medical advice is needed.

Could TECAR Therapy Help After a C-Section?

TECAR is being investigated as a possible additional treatment for painful caesarean scars. The question is whether adding it to scar care provides benefits beyond the effects of usual care, recovery over time and the treatment experience itself.

What Does the Direct Research Show?

A 2025 paper in BMJ Open describes the NOCEPAIN trial protocol. It sets out a study designed to compare active TECAR with a sham treatment in women whose C-section scars remain painful at six to eight weeks after birth. Both groups are also taught scar self-massage.

This is relevant research, but the paper is a study protocol, rather than a report showing that the treatment works. It cannot establish the size of any benefit, how long improvement might last or which patients are most likely to respond. NOCEPAIN study protocol

What About Other Postnatal TECAR Studies?

Some research has investigated radio frequency treatment for perineal symptoms after vaginal birth.

A small randomised study published in 2020 found no significant benefit for its main outcome of pain at rest on the second day after treatment. It did report improvements in some secondary measures, including discomfort while walking. These findings need to be interpreted in the context of the study’s size and design. Bretelle and colleagues, 2020

Perineal injuries and abdominal surgical scars are different. These results cannot be used as proof that TECAR treats C-section scars.

What Does This Mean for Scar Tissue Therapy?

Scar tissue therapy is a broad description, rather than one specific treatment. Depending on the assessment, rehabilitation may involve advice, gradual exposure to touch, gentle scar mobilisation once appropriate, and exercises to support comfortable movement.

The aim should be a meaningful improvement in symptoms and everyday function.

Can TECAR Break Down Scar Tissue or Remove Adhesions?

There is insufficient direct clinical evidence to promise that TECAR breaks down C-section scar tissue, removes internal adhesions or restores tissues to their pre-surgery state.

A change in comfort or movement would not, on its own, prove that an internal adhesion had been removed.

Similarly, TECAR should not be presented as a way to erase a scar or guarantee a flatter abdomen. NHS guidance explains that scars commonly fade over time, but cannot be completely removed. NHS information on scars.

Where Might TECAR Fit Into Rehabilitation?

If considered appropriate after assessment, TECAR would be an optional addition to a wider rehabilitation plan.

Before proceeding, your clinician should explain:

• What symptom or functional difficulty treatment is intended to address.

• What evidence supports the proposed approach and where uncertainty remains.

• What other options are available.

• How progress will be measured and when treatment will be reviewed.

A treatment plan should be adjusted if it is not producing worthwhile improvement.

When Can Scar Rehabilitation Begin After a C-Section?

The timing depends on wound healing, any complications and the type of care being considered.

For direct scar massage, NHS advice is to wait until the wound is fully healed. There should be no open areas or remaining scabs. Check with your midwife or GP if you are unsure. NHS advice on when to start scar massage

This guidance does not establish a start date for TECAR. Being six or eight weeks postpartum is not automatic clearance for treatment: suitability requires an individual assessment and adherence to the device’s instructions.

Can You Have TECAR Therapy During Pregnancy?

Winback lists pregnancy among its main contraindications. TECAR should therefore not be offered during pregnancy, including for discomfort around a previous C-section scar. Winback safety information

If you are pregnant and have symptoms around an existing scar, speak to your maternity team. They can assess the symptoms and advise on suitable care.

Planning a C-section is also an opportunity to discuss recovery with your maternity team, rather than starting TECAR as a preventative treatment.

Who Needs Additional Screening Before Treatment?

An assessment should identify medical conditions and other factors that could make treatment unsuitable.

Winback lists pacemakers, electrical implants and active cancer among its main contraindications. Other concerns, such as reduced sensation, infection or problems with wound healing, also require careful clinical assessment. This is not an exhaustive safety checklist; the clinician must follow the instructions for the specific device being used. Winback treatment information

Tell your clinician about your operation, any complications, medical conditions, implanted devices and whether you are breastfeeding.

When Should You Seek Medical Advice Instead?

Contact your midwife or GP promptly if your wound becomes increasingly red, swollen or painful, produces pus or foul-smelling fluid, or if you develop severe pain or heavy bleeding.

Chest pain, sudden breathlessness or a painful, swollen leg require urgent medical attention. These symptoms need medical assessment rather than a routine scar therapy appointment. NHS guidance on C-section recovery
