What is bioadaptive impulse therapy?

Bioadaptive impulse therapy is a specially designed and regulated electrotherapy which is used in all products of the Keytec GmbH keyseries and which has already proven its effectiveness for many years. The influence of electrical impulses on the human body was explained by the Gate-Control-Theory as early as 1965. Since then, numerous application possibilities have become known.

Current research and developments in this field now make it possible to use technology that allows the impulses to be adapted to the body in almost real time. An initial impulse is transmitted into the body just beneath the first layers of skin. This means that the underlying tissue is not inadvertently affected. This procedure enables a measurement of the tissue attenutation properties and thus the body’s own reaction to the impulse, which can be evaluated by an integrated processor. Based on this measurement data, the keyseries bioadaptive devices adapt and generate a response signal in a fraction of a second. The adaptation does not only occur once, but many times per second. Due to the constant variance of the impulses and due to the individually selected alternating sequences of the treatment algorithms, regulative and functional changes occur during the treatment period. The bioadaptive impulse therapy is thus ultimately controlled by the patient’s body itself.

These impulses have a positive influence on the autonomic nervous system and thus on the body’s own adaptation and regulation processes. This is why the therapy is used in particular to alleviate acute and chronic complaints and to treat muscular and organic dysfunctions.

The functional principle of bioadaptive impulse therapy

1. Impulse emission

The first impulse is emitted in the physiokey as soon as there is skin contact.

2. Impulse absorption

This impulse, however, only penetrates the skin in the range of a tenth of a millimetre. The receptors of the skin then process this stimulus.

3. Impulse transmission

Once the impulse has been absorbed by the body, the information is transferred to the spinal and neurohumoral levels.

4. Impluse adaptation

The “response reaction” in the form of a change in tissue resistance properties is measured by physiokey within microseconds. The renewed impulse delivery is then already adapted to this “body response”.

Goal of bioadaptive
impulse therapy
treatment aims

Treatment with bioadaptive impulse therapy has the following objectives:

  • Rapid relief of acute and chronic pain
  • Improvement and restoration of function

Following therapy with the keyseries devices, more than 80% of the patients notice a significant change in their complaints. The users report an improvement in the tension state of the muscles. A rapid decrease in soft tissue swelling has been observed in a large number of patients. This is probably due to a rapid lymph drainage caused by the special impulse technique.

Indications and areas of application

The aim of bioadaptive impulse therapy is the relief of acute and chronic pain, the improvement of blood circulation, passive muscle stimulation and improvement and recovery of function for the following areas of application:

  • Nervous system
  • Musculoskeletal system
  • Digestive tract
  • Urogenital area

The device is applied to intact skin. Direct application on injured skin is not advised.
The recommend treatment duration for the device ranges from a few minutes to a maximum of 1 hour. The treatment is usually performed by moving the device on the skin.
The field of application is primarily in trained, professional therapy, but also extends to trained private users.


Bioadaptive impulse therapy must not be used in the following cases:

  • On-demand-type cardiac pacemaker. or other electrically powered implant
  • Electrode placement over malignant tumours
  • Use over open wounds
  • Patients prone to seizures
  • Alcohol intoxication
  • Pregnancy

Side effects

Bioadaptive impulse therapy is extremely low in side effects. However, the following cases can be understood as side effects.

During treatment, symptoms may intensify as the body “dynamises”. In individual cases, this may be accompanied by increased pain, sore muscles and other reactions. However, these usually subside after a short time. If they last longer, interrupt the application for a few days and consult a health professional if needed.

Like all metals, the steels of the exchangeable electrodes of medkey, physiokey, and sanakey and contain traces of nickel. If you have a strong nickel allergy, skin irritation may occur.
