What You Need to Know about Shortwave Therapy Device?

In modern rehabilitation medicine, physical therapy methods are becoming increasingly diverse. Among them, the shortwave therapy device, with its unique deep thermal and non-thermal effects, has become an indispensable piece of equipment in major hospitals, rehabilitation centers, nursing homes, and other institutions. This article will provide you with a comprehensive understanding of the powerful functions of the shortwave therapy device from the perspectives of product mechanism, scope of application, clinical use, and economic benefits.

1. What Is A Shortwave Therapy Device?
A shortwave therapy device is a type of high-frequency electrotherapy equipment. Its operating frequency is 27.12 MHz, with a wavelength range between 10 and 100 meters. It utilizes electromagnetic energy generated when high-frequency current passes through human tissues, converting it into deep heat or non-thermal biological effects to achieve therapeutic goals such as reducing inflammation, relieving pain, and promoting tissue repair. Unlike low-frequency and mid-frequency electrotherapy, shortwave therapy can penetrate deep into muscles, joints, and internal organs, delivering a "from the inside out" treatment effect.

2. What Are The Mechanisms of Action of Shortwave Therapy?

2.1 Thermal Effect: Deep Heating with Clear Efficacy
When high-frequency current acts on the human body, heat is generated through three mechanisms: ohmic loss, dielectric loss, and resonant absorption. This thermal effect produces the following significant actions:

Deep pain relief: Reduces the excitability of sensory nerves, interferes with pain signal transmission, and relieves muscle spastic pain.

Improved circulation: Dilates blood and lymphatic vessels, accelerates blood flow, increases tissue permeability, and promotes the elimination of metabolic waste.

Anti-inflammatory effect: Enhances local immune function, promotes the absorption of chronic inflammation, and supports tissue repair.

Clinical tip: In the early stages of acute inflammation, the use of thermal doses is not recommended; priority should be given to non-thermal, heat-free treatment.

2.2 Non-Thermal Effect: Small Dose, Big Impact
When using low doses or pulse modes, patients may not feel obvious heat, yet the tissues still produce a series of positive biological responses, including:

Inhibiting the progression of acute inflammation;

Promoting the regeneration of nerve tissue and granulation tissue;

Regulating cell membrane potential and ion distribution, thereby improving cellular function.

This gives the shortwave therapy device unique advantages in the treatment of acute inflammation and early intervention for nerve injuries.

3. Which Conditions Are Suitable for Shortwave Therapy?
Shortwave therapy has an extremely broad range of indications, covering multiple system disorders:

3.1 Inflammatory Diseases

• Chronic and subacute inflammation (e.g., pelvic inflammatory disease, cholecystitis, prostatitis)
• Acute inflammation (also applicable using the non-thermal mode)

3.2 Soft Tissue Injuries

• Fibrositis, sprains and strains, muscle strain, muscle spasms
• Poor wound healing, postoperative tissue repair

3.3 Bone and Joint Diseases

• Osteoarthritis, scapulohumeral periarthritis (frozen shoulder)
• Delayed fracture healing, hemarthrosis, joint effusion

3.4 Internal Organ Diseases

• Gastroduodenal ulcer, chronic gastritis, colitis
• Nephritis, acute renal failure, pelvic inflammatory diseas

3.5 Rheumatic and Immune Diseases

• Rheumatoid arthritis, osteoarthritis
• In addition, shortwave therapy is also effective for conditions such as segmental nerve reflex regulation and chronic pain syndromes.

4. Clinical Application Operation Points and Safety Precautions

4.1 Electrode Placement Methods

Opposition Method (Contralateral Placement): The lesion is positioned between two electrodes, with electric field lines penetrating deep into the tissue. Suitable for deep tissue lesions.

Juxtaposition Method (Ipsilateral Placement): Electrodes are placed side by side on the body surface, providing a shallower effect. Suitable for superficial tissues or both sides of a joint.

4.2 Dose Grading (Based on The Patient‘s Subjective Sensation of Heat)

4.3 Safety Precautions

- Remove all metal objects from the patient’s body before treatment.

- The treatment area should be dry; avoid sweat or wet dressings.

- Maintain an appropriate gap between the electrodes and the skin. Increase the gap for uneven body surfaces.

- High heat is prohibited in sensitive areas such as the head, eyes, and testicles.

-Cables must not cross or contact the skin during treatment to prevent short circuits and burns.

-It is recommended to use copper mesh shielding in the high-frequency electrotherapy room to reduce electromagnetic interference.
