Short wave therapy in Chennai

Short wave diathermy, also known as SWD, employs electromagnetic energy to produce heat and treat joints and body tissues. The process accentuates blood flow, relieves pain and improves mobility in the tissue. It enhances flexibility in the joints and connective tissue, thus relieving arthritis. Short wave therapy in Chennai, is available at Dr Karunakaran spine centre, which has a whopping 22 years experience in spine care.

SWD is applied as pulsed or continuous energy waves. Short wave therapy in Chennai enables patients to comfortably participate in rehabilitation processes. However, it has its own limitations by not allowing children and pregnant women to take therapy besides barring those with metal implants and pacemakers.

The therapy is promotes cell growth and enhances cell repair and is effectual for those suffering rheumatoid arthritis and osteoarthritis.

Healing attributes of short wave therapy in Chennai

Short wave therapy, also known as short wave diathermy (SWD), employs electromagnetic energy to induce heat in joints and tissues, as a part of healing treatment. The heat thus produced promotes blood circulation and relieves pain. The term dia(through) thermy(heat) explains the process. It is also efficient in treating kidney stones and pelvic inflammatory diseases.

The blood circulation enhances flexibility in the joints and connective tissue, thus answering discomfort caused due to arthritis. The patients accentuate their range of motion and participate in the rehabilitation process with better ease.


Instead of applying heat directly, SWD machine generates heat waves from the specified tissue. SWD is a part of another treatment whose frequency and length varies. The therapy uses three frequencies including 27.12 MHZ (wavelength 11m), 13.56 MHZ (wavelength 22m) and 40.68 MHZ (wavelength 7.5m).

It is employed either as pulsed or continuous energy waves which treat pain and muscle spasms. The waves are capable of reaching as deep as two inches below skin level. Sub acute and chronic conditions are treated with continuous SWD, while acute lesions are treated with pulsed SWD.

Short wave diathermy units could be inductive units or capacitive units to create local heating in tissues. The inductive SWD units comprise of coils whose magnetic fields which projects on target tissue and create circular electric field. Capacitive units, on the other hand, employ condenser plates to transfer oscillation of electric field between the plates and create local heating in the tissue.

The therapy is applied to procure uniform rise of temperature in deep tissues and interior parts of joints.

Short wave therapy in Chennai: Risks and limitations

Owing to effectual bone penetration, SWD is not recommended for children since the therapy might hamper growth and lead to other side effects. Also it is not advisable for those equipped with metal implants, pacemakers and deep brain stimulators. SWD may affect metal devices such as bone pins, dental filings and metal sutures and may cause burns near the tissue.

Since electromagnetic waves can heat water, the therapy is not suitable for those with excessive fluid accumulation, pregnant or menstruating uterus. A rule of “no water no metal” is observed while employing SWD.

Hemorrhage, venous thrombosis or phlebitis, arterial diseases, disturbed skin sensation, x ray exposure are few conditions which SWD treatment could be avoided.


SWD is preferable if target areas are interior of large joints, like knee, hip, ankle for instance. It is used instead of ultrasound, when wider area of application is required. Short wave therapy in Chennai is employed to treat joint ailments such as rheumatoid arthritis and osteoarthritis.

SWD promotes cell growth, assists damaged cells to regain normalcy and heals wounds. SWD along with hot packs and iso-kinetic exercises, mitigate pain and encourage function in patients suffering from knee osteoarthritis. It also increases flexibility in patients who have low back pain.

SWD also provides relief to symptoms such as fibromyalgia, myositis, neuralgia, tenosynovitis, burn injuries and bursitis.

SWD treats musculo-skeletal disorder, ligament sprains, muscle strains, frozen shoulder, degenerative joint disease and chronic inflammatory conditions including tendinitis.
