Shortwave Diathermy (SWD) in Indirapuram

Shortwave diathermy uses high-frequency electromagnetic energy to heat tissues deeper than a hot pack can reach. It's used to reduce stiffness and muscle spasm in larger joints and the spine, usually before stretching and exercise.

How SWD heats tissue

The machine generates an electromagnetic field between two plates or through a drum placed near the body. Tissues absorb the energy and warm from within. You feel a gentle, deep warmth, never burning.

Pulsed settings produce little heat and are sometimes used for their proposed effects on tissue repair, though evidence for that is limited.

Where it fits

Deep heat can ease stiffness in knee and hip arthritis, spinal stiffness and chronic muscle tension. As with other heating methods, it's a preparation for movement. The mobility and strengthening work that follows is what produces lasting change.

Safety

Metal is a hazard with SWD. We ask about metal implants, joint replacements, pacemakers, IUDs, jewellery and hearing aids before every course. It's not used over a pregnant abdomen, over areas of reduced sensation, poor circulation, active cancer, DVT, infection, over the eyes, or on growing bone in children.

Medical note

This page is general information, not a diagnosis. Treatment is planned after an in-person assessment by a physiotherapist, and we refer you to a doctor where symptoms need medical review first. If you have sudden weakness, loss of bladder or bowel control, chest pain or severe unexplained pain, seek emergency care.

Frequently asked questions

Can I have SWD with a knee replacement?

No, not over or near the metal implant.

Should it feel hot?

Only comfortably warm. Tell the therapist straight away if it feels too hot.

How often is it used?

Typically a few times a week for a limited period, alongside exercise.

What is Shortwave Diathermy (SWD)?

Shortwave diathermy (SWD) uses high-frequency electromagnetic energy to produce deep heat in muscles and joints, easing pain and stiffness.

Who can benefit from Shortwave Diathermy (SWD)?

People with stiff, painful joints and muscles, such as arthritis, frozen shoulder and chronic back pain.

What conditions can Shortwave Diathermy (SWD) help with?

It commonly helps with knee osteoarthritis, lumbar spondylosis, frozen shoulder physiotherapy, cervical spondylosis and ankylosing spondylitis. Chronic muscle spasm is also treated.

What are the benefits of Shortwave Diathermy (SWD)?

Deep, comfortable warmth that relaxes muscle, eases pain and makes stretching easier.

How does Shortwave Diathermy (SWD) work?

The electromagnetic field makes tissue molecules vibrate, generating heat deeper than a hot pack can reach.

What happens during a Shortwave Diathermy (SWD) assessment?

We check for metal implants, pacemakers, pregnancy and sensation before use.

What happens during a Shortwave Diathermy (SWD) session?

The area is positioned comfortably, Shortwave Diathermy (SWD) is applied for about 15 to 20 minutes within a longer session, and it is usually followed by exercise such as passive, assisted and active range of motion and stretching exercises, because it works best as part of an active plan.

What treatments are used with Shortwave Diathermy (SWD)?

It is usually combined with manual therapy, heat therapy (thermotherapy), interferential therapy (IFT) and spinal traction therapy, depending on your assessment and how you respond.

What exercises are commonly used with Shortwave Diathermy (SWD)?

Common exercises include passive, assisted and active range of motion, stretching exercises, pendulum exercise and pelvic tilts. They start at a comfortable level and are progressed as you improve.

How long does a Shortwave Diathermy (SWD) session take?

A session usually takes 15 to 20 minutes within a longer session.

How many Shortwave Diathermy (SWD) sessions might be needed?

A limited number of sessions during stiff or painful phases.

How often should Shortwave Diathermy (SWD) sessions be scheduled?

Two to three times a week.

Can Shortwave Diathermy (SWD) help reduce pain?

Yes, through deep heat. Pain relief is one of the main aims of treatment.

Can Shortwave Diathermy (SWD) improve mobility?

Yes, by preparing tissue for stretching.

Can Shortwave Diathermy (SWD) improve strength and flexibility?

No. Strength and flexibility come from the exercises your physiotherapist sets alongside it.

Can Shortwave Diathermy (SWD) be provided at home?

No. SWD uses clinic equipment.

Is Shortwave Diathermy (SWD) suitable after surgery or injury?

Only once healed and never over metal implants.

Is Shortwave Diathermy (SWD) suitable for older adults or children?

Used with care in older adults; not used over growing bones.

What precautions should be considered with Shortwave Diathermy (SWD)?

Not used with metal implants, pacemakers, pregnancy, cancer, reduced sensation or over wet dressings.

When should I consult a physiotherapist about Shortwave Diathermy (SWD)?

When joint or muscle stiffness is limiting exercise. You can book an assessment at our Indirapuram clinic or ask for a home visit.
