What is arthritis 

Arthritis (Antient Greek - ἄρθρον - joint) - the collective designation of any diseases (lesions) of the joints.

It can be a major disease (eg, spondylitis) or a manifestation of another disease (eg, rheumatism). Occurs in acute and chronic forms with lesions of one or more (polyarthritis) joints. Among the causes are infections (tuberculosis, brucellosis), metabolic disorders (eg, gout), trauma, etc.


There are several diseases where joint pain is primary, and is considered the main feature. Generally when a person has "arthritis" it means that they have one of these diseases, which include:

  • Osteoarthritis
  • Rheumatoid arthritis
  • Gout and pseudo-gout
  • Septic arthritis
  • Ankylosing spondylitis
  • Juvenile idiopathic arthritis
  • Still's disease

Joint pain can also be a symptom of other diseases. In this case, the arthritis is considered to be secondary to the main disease; these include:

  • Psoriasis (Psoriatic arthritis)
  • Reactive arthritis
  • Ehlers-Danlos Syndrome
  • Haemochromatosis
  • Hepatitis
  • Lyme disease
  • Sjogren's disease
  • Hashimoto's thyroiditis
  • Celiac disease
  • Non-celiac gluten sensitivity
  • Inflammatory bowel disease (including Crohn's disease and ulcerative colitis)
  • Henoch–Schönlein purpura
  • Hyperimmunoglobulinemia D with recurrent fever
  • Sarcoidosis
  • Whipple's disease
  • TNF receptor associated periodic syndrome
  • Granulomatosis with polyangiitis (and many other vasculitis syndromes)
  • Familial Mediterranean fever
  • Systemic lupus erythematosus

An undifferentiated arthritis is an arthritis that does not fit into well-known clinical disease categories, possibly being an early stage of a definite rheumatic disease.


  • swelling
  • change in the structure and shape of the joint
  • pain and loss of joint function
  • inflammation
  • redness of the joint

All types of arthritis accompany pain, the nature of which depends on the type of arthritis. Also, arthritis is characterized by redness of the skin, restriction of mobility in the joint, a change in its shape. Often the joints that are susceptible to the disease unnaturally crunch during exercise. A person with arthritis may experience difficulties in cases when physical force is needed.


Diagnosis is made by clinical examination from an appropriate health professional, and may be supported by other tests such as radiology and blood tests, depending on the type of suspected arthritis. All arthritides potentially feature pain. Pain patterns may differ depending on the arthritides and the location. Rheumatoid arthritis is generally worse in the morning and associated with stiffness lasting over 30 minutes. However, in the early stages, patients may have no symptoms after a warm shower. Osteoarthritis, on the other hand, tends to be associated with morning stiffness which eases relatively quickly with movement and exercise. In the aged and children, pain might not be the main presenting feature; the aged patient simply moves less, the infantile patient refuses to use the affected limb.


There is no known cure for either rheumatoid or osteoarthritis. Treatment options vary depending on the type of arthritis and include physical therapy, lifestyle changes (including exercise and weight control), orthopedic bracing, and medications. Joint replacement surgery may be required in eroding forms of arthritis. Medications can help reduce inflammation in the joint which decreases pain. Moreover, by decreasing inflammation, the joint damage may be slowed.

DENAS therapy is also actively used to treat and eliminate the symptoms of various forms of arthritis, as well as inhibit the progression of the disease.

The basis of DENS-therapy is the effect on the biological active zones with the help of a neuroimpulse.

With the help of the course of action, the DENAS devices achieve a stabilizing effect, which is most valuable for chronic diseases.

For the treatment of joint arthritis at home and medical facilities, we recommend the following kit: DENAS PCM device with DENAS applicators

Method of DENS therapy in treatment of arthritis 

Lumbosacral zone

In severe pain syndrome, it is recommended to perform procedures on demand several times a day. Course 10 - 20 days. 

1. The area of the affected joint. Mode "Therapy": with a pronounced pain syndrome at a frequency of 140Hz or 200Hz as pain and inflammation decrease - 77Hz, 20Hz, 7710Hz., 9.6Hz, 1.6Hz. The exposure time is from 10 to 20 minutes or the program "Joints", "Pain", "Severe Pain"

For a more comfortable and efficient procedure, use the DENS-applicator 

2. Symmetrical healthy joint (with unilateral defeat) in the "Therapy" mode 10Hz or 77Hz, 5 minutes or the DER program

For a more comfortable and efficient procedure, use DENAS applicator 

3. The lumbosacral zone is treated with lesions of the joints of the lower extremities. Mode "Therapy"

at a frequency of 77Hz, 20Hz, 9.6Hz for 5-10 minutes or the program "BACK". 

Cervical-collar zone

For a more comfortable and efficient procedure, use DENAS applicator

4. Cervical-collar zone - when the joints of the upper extremities are affected. Mode "Therapy" at a frequency of 77Hz, 20Hz, 9.6Hz for 5-10 minutes or the program "BACK". 

For a more comfortable and efficient procedure, use DENAS applicator

Additional options for the treatment of arthritis:

1. The device DENAS-Vertebra II: with severe pain program "B", with a moderate - the program "C", once a day, the course 10-14 days.

2. The device DENAS-Osteo: the program "Relaxation", 1-2 times a day, the course 10-14 days. More information here

3. Medical clothing: DENAS-OLM-1 blanket, 1-2 procedures per day, 20-40 minutes or DENAS-OLM-2 waistcoat, 1-2 procedures per day, 40-60 minutes.

There are contraindications. Before use, it is recommended to consult a doctor.
