Non-Invasive Neuro Stimulation

What is Non-Invasive Neuro Stimulation | What to expect from a typical treatment |  Links


Non-Invastive Neuro Stimulation is a therapy that has been in Australia for many years, and is continually growing in popularity due to its effectiveness. Sarah was trained as a SCENAR Therapist in 2002, and as a result is one of the longest standing therapists in this field in Australia.


SCENAR (Self Controlled Energo Neuro Adaptive Regulator) is a hand held electro-stimulation medical device. It is a certified pain relief device that was designed by a Russian Neurologist to relieve pain and restore function. SCENAR is non-invasive and does not involve needles, drugs or surgery.


Sarah with a patien performing SCENARSCENAR is able to alleviate pain and assist people to restore function. SCENAR is used for:

   •  musculoskeletal problems

   •  surgery

   •  trauma

   •  bursitis

   •  dental problems

   •  physical therapy

   •  during labour


Key Therapy is one of the most recent variations of Non-Invasive Neurostimulation. Due to the additional benefits to clients, Sarah has become a trained Key Therapist.

Key Therapy is used to:

   •  reduce chronic and acute pain

   •  improve blood circulation

   •  perform passive muscle stimulation

   •  restore functional restoration


Key Therapy also has the added benefit of iontopherosis, which means the device can be used in conjunction with creams or gels as part of your treatment plan.


Key Therapy also offers a user friendly home device (Sanakey) that can provide ongoing treatment in the comfort of your home. Sarah is an authorised reseller for Sanakey, and can also provide training for both home devices (Sanakey) and professional devices (Physiokey).


Bio scenar & PhysiokeyYour initial appointment will involve you filling in some paper work. Your therapist will then take a comprehensive medical history. Following this, you will receive a thorough explanation and demonstration of the non-invasive neurostimulation device being utilised to assist you with your complaint.


Your treatment plan will be discussed with you to ensure it meets your goals, and works towards increasing your function and improving your health and wellbeing. Your initial appointment will usually take approximately one hour.


The device is placed on your body and you are asked when you feel a slight tingling sensation. This is not a painful experience. The device is brushed over your body throughout your treatment. During this time, you may notice some sensations in different areas in your body. You are encouraged to explain these sensations as they occur. This is to aid in directing your treatment.


SCENAR and Key Therapy are unique in their ability to be able to locate exactly where your body requires assistance to relief pain or restore function. The device will then deliver the necessary treatment to that area. Non-Invasive Neurostimulation will assist to put your body in a position to heal itself by opening up nerve pathways and ensuring a clear message is being sent from the brain to the area requiring treatment.


SCENAR and Key Therapy aim at creating a change in your current condition. Any change means that the body has listened to the treatment and it is therefore working. However, some people may have an increase in pain, especially following their first treatment. This is a positive sign; as it means the body is listening to the problem, responding quickly to treatment and beginning to restore function. An increase in pain or symptoms does not usually last for any longer than 24hours.


The number of sessions you require will depend on your condition. Some acute issues will resolve in as few as three sessions. Other chronic, long lasting conditions will require a series of sessions. You will be given an estimate of the number of treatments you may need on your first session.


Contraindications: If you have a pacemaker you are unable to receive SCENAR or Key therapy. Please ensure you inform your therapist if there is any chance you may be pregnant. You are still able to receive treatment, however, there are certain protocols to be avoided during this special time.

“This trial demonstrated improvements in function in individuals with MTPs (Myofascial Trigger Points)following INS (Interactive Neurostimulation) therapy, which may be of clinical significance in certain patients with neck or shoulder pain. Further large-scale clinical trials are required to confirm this effect and to determine if INS also reduces pain and neck disability.”

Interesting to note treatment time was only 10min. At least 15 to 20 minute is required I think to get an efficient cascade of cytokines.
