Enraf-Academy Introduction Note

  • Users of Enraf-Nonius treatment devices must be trained in how to use the system properly and have the appropriate skills.
  • Any treatment instructions regarding treatment location, duration and strength require medical knowledge and should only be given by authorised doctors, therapists and health professionals. It is imperative that these instructions are followed.
  • Before using Enraf-Nonius equipment, read, understand and practice the instructions for use. Know the limitations and hazards associated with using the device. Also observe the precautionary and operational decals placed on the unit.

Biofeedback and myofeedback

Myofeedback is a form of feedback, in which the patient receives electronically recorded information about his own physiological processes. The electromyographic recording used in the diagnostics and treatment of the moving mechanism is an indispensable supplement to the study of movement. When we place electrodes on the skin to obtain information from an EMG signal about the underlying musculature, we must be acquainted with the development of the EMG signal and the construction and function of the motor mechanism.  Thus, properties and mutations in the musculature, the joints system, the sensory and the neural system can be found in the motor system and also in the EMG recording.

Surface EMG provides us with detailed information about the organ-specific properties of a muscle, such as:

  • the activation of the muscle;
  • the muscle’s capacity for relaxation;
  • coordination between muscles;
  • the tiredness of a muscle;
  • the capacity of a muscle to lengthen.

This makes myofeedback especially suitable as a measuring instrument for charting our locomotive operations

Biofeedback is the process of gaining greater awareness of physiological functions primarily using instruments that provide information on the activity of those functions, with a goal of being able to manipulate them at will. The Enraf-Nonius Myomed systems allows for biofeedback (besides myofeedback) by means of pressure feedback. This is very usefull for pelvic floor training. Biofeedback is done with cavity probes (vaginal or anal) and gives feedback on the the coordinated action of the pelvic floor muscles. It is a very funtional approach for re-educating and relaxation of the pelvic floor and can solve many highly inconvenient dysfuntions in the pelvic area.

Biofeedback and myofeedback Indications and Contra-Indications


  • Loss of coordination (voluntary muscles)
  • Craniomandibular dysfunction
  • Tension headache / Migraine
  • Stress-related disorders
  • Low-Back Pain
  • Respiratory diseases
  • Orthopedic, post-traumatic and post-surgical disorders
  • Peripheral nerve lesions
  • Mimic (Facial) Rehabilitation
  • Pelvic Floor Reeducation (Incontinence)
  • Dysphagia


Because Myofeedback therapy does not “do” anything to the body, few contraindications exist. Myofeedback therapy is not recommended for persons with severe psychosis, depression, or obsessional neurosis, nor for debilitated patients or those with psychopathic personalities. However, because resulting functional improvements can require strenuous physical effort, individuals interested in Myofeedback may need to be aerobically fit.

Precautions and Warnings

Myofeedback is dangerous for diabetics and others with endocrine disorders, as it can change the need for insulin and other medications. Please check with the doctor to see whether this is an appropriate treatment for you.

Please consult the Instructions for Use for more information on indications and contra-indications and for warnings and recommendations.

The above indications and contra-indications originated from the 6-Series_User_Manual_1600751_4B_EN.
