Contra indications:
It is always advisable to consult with your physician
before starting any exercise program. Ongoing research
in the field of Whole Body Vibration (WBV) indicates
that many conditions can actually benefit from this form
of therapy. However, if you suffer from any of the
following contraindications it is imperative that you
discuss Whole Body Vibration therapy with your
physician before beginning any training program with
DKN equipment.
Please do not use DKN or any WBV device at all if you
have any of the following:
Absolute contraindications:
• Acute inflammations, infections and/ or fever
• Acute arthropathy or arthrosis
• Acute Migraine
• Fresh (surgical) wounds
• Implants of the spine
• Acute or chronic Deep Vein Thrombosis or other
thrombotic afflictions
• Acute disc related problems, Spondylosis, gliding
• Spondylolisthesis or fractures
• Severe Osteoporosis with BMD < 70mg/ml
• Spasticity (after stroke/ spinal cord lesion...)
• Tumors with metastases in the musculoskeletal
system
• Vertigo or positional dizziness
• Acute Myocardial Infarction
Relative contraindications:
• Pregnancy
• Epilepsy
• Gallstones, Kidney stones, Bladder stones
• Articular Rheumatism and Arthrosis
• Heart failure
• Cardiac dysrhythmias
• Cardiac disorders (Post MI)
• Metal or synthetic implants (e.g. pacemaker, artificial
cardiac valves, recent stents, or brain implants)
• Chronic back pain (after fracture, disc disorders or
spondylosis)
• Severe Diabetes Mellitus with peripheral vascular
disease or neuropathy
• Tumors (excluding metastases in the musculoskeletal
system)
• Spondylolisthesis without gliding
• Movement disorder and Parkinsons
• Chondromalacia of the joints of the lower extremities,
osteonecrosis and chondrosis
• Arterial circulation disorders
• Venous insufficiency with ulcus cruris
• Lymphatic edema
• Postoperative wounds
• Acute Rheumatoid Arthritis

WHOLE BODY VIBRATION: How it works
The Plate produces a vibration through which energy is
transferred from the platform to the body. By standing
on the Plate, your body automatically adjusts to the
vibrations. Remember that human bodies are made to
absorb vertical vibrations due to gravity acceleration
effect. This mechanical stimulus produces an
involuntary stretch reflex which, depending on the
selected frequency, results in muscles vigorously
contracting 30 to 50 times per second. The mechanical
stimulation generates acceleration forces working on
the body. These forces cause the muscles to lengthen,
and this signal is received by the muscle spindle, a
small organ in the muscle. This spindle transmits the

Basically the Whole Body Vibration platform recreates
the muscle stretch reflex according to the following
process:
1. Stimulus: a tap on tendon causes a muscle stretch

2. Receptor: the receptors in muscles and joints note
