The Story

Australian Tongan inventor Mr Geoffrey Redmond first noticed that his mother at the age of 86, was having great difficulty with her short-term memory and being able to walk without pain. He considered exercise as the obvious solution.

The problem being: “How do you exercise a person that cannot move without pain?” 

Answer: “Have a machine to do the moving for them. Thereby allowing them to receive the miraculous benefits of exercise.”

Since first using her REVIVER and now at the age of 91,

she maintains her 3 to 4-minute daily exercise routine on the device. Mrs Redmond continues to improve her memory and ability to walk distance without pain, while maintaining her happy disposition.

Geoffrey's Testimonial

At 60, I was overweight with a number of health issues such as gout and joint pain, which limited my ability to be active and exercise. I use the manual ADAM REVIVER at home, once or twice a week for around 6 mins at a time.​

Now at the age of 63, I am doing a lot of the things that I used to do at a much younger age, such as boxing and sprinting. REVIVER is proving that balance is a fundamental foundation of exercise and its use provides benefits that go well beyond current methods of exercise, in activating areas of the body that have become dormant.

"I believe the benefit of REVIVER is its ability to produce strength and healing signals that consistently and uniformly radiate throughout the body"

Scientific Principles of REVIVER

Dr Ben Sinclair
Research Fellow, Department of Neuroscience, Monash University

Dr Benjamin Sinclair attained his PhD at the University of Queensland and has worked as a lecturer in MRI physics at University of Queensland and as a Research Fellow at the University of Melbourne. He is now a Research Fellow in the Department of Neuroscience at Monash University in Melbourne Australia.

His major area of study and research is in the field of brain imaging. Dr Sinclair has published papers on a range of topics including supernova cosmology, space plasma physics, the heritability of brain networks and effects of physical exercise interventions on brain atrophy in elderly people.


Thus far, self-reports by users of the REVIVER exercise machine and simple observations by Isodynamics Centre staff indicate a myriad of benefits. A number of users demonstrate immediate and marked improvements in walking and posture, which persists through regular use. Regular use also produces visually evident increases in muscle tone, and some users report improvements in memory and reduction in pain symptoms from pre-existing ailments. Rapid improvements in some users are best explained in terms of neurological, rather than muscular phenomena. The closest precedent in scientific literature is the emerging field of neuromodulation.

In what follows, the probable scientific basis of the observed improvements is explored. The physical benefits obtained from the use of the REVIVER derive from improvements in both muscular and neural systems. These improvements can be explained by a number of principles; neuroplasticity, neuromodulation, assisted motion, recruitment of full-body automatic/reflex actions and utilisation of gravity.

1 Muscular Effect

Muscular atrophy is the reduction in muscle mass, caused primarily by lack of physical activity. Use of the REVIVER has the ability to reverse this effect considering the following principles.
1.1 Assisted Motion
For elderly people or people with a physical impediment, a large range of natural motions and muscular activation patterns will not be available to them. Assisted motion is a prominent technique used in neuromuscular rehabilitation whereby some mechanism is used to help the person perform a motion that they would otherwise be unable to perform. For example, robotics are used in the therapy of chronic stroke patients to aide in limb motor control and has been shown to increase motor control (Kwakkel et al., 2008; Prange et al., 2006). In some studies, this improvement is greater than conventional movement therapies (Lum et al., 2002).
The REVIVER machine fully supports the participant whilst moving them through a range of body positions. These body positions engage strongly and simultaneously a set of core and peripheral muscles required to keep the body upright. This engagement will strengthen those muscles and strengthen the neural pathways from the brain to those muscles, which may have weakened through non-use.
1.2 Automatic Responses
There are some cases in neurology where a specific function may be impaired, but if that function is part of a distinct or more complex process, then the impaired function can nevertheless be recruited. For example, some patients in advanced stages of Alzheimer’s disease may have impaired speech and communication, but can nevertheless sing along to familiar songs, and experience temporary improvements in communication (anecdotal) and reduction in agitation and anxiety (Gerdner, 2005) subsequent to music therapy. The self-righting reflex in response to falling is an automatic reaction requiring minimal conscious decisions or actions.
The REVIVER activates this response by placing the participant on positions at the edge of, and beyond their balance. This strong survival response appears to be recruiting motor patterns and muscles which had become weak through lack of use and reduced signalling, and which are no longer activated through the participant's other physical activities or daily living.

1.3. Gravitational Effects
All-natural human movements evolved within the constraints of gravity and counteracting the force of gravity is a major component of these movements. The most striking example of the necessity of gravity in human physical function is the dramatic wastage of muscle tissue in astronauts exposed to periods of zero gravity. 
One of the major design principles of the REVIVER is to maximise the effects of gravity and to maximise the participants' counter-reaction to gravity. In an upright position, as utilised in most physical activities and sports, minimal force is required to counteract gravity as the centre of gravity is directly above their support base. In a tilted position, the participant has to counteract torques (rotational forces), due to their centre of gravity being displaced from their support base. Counteracting these torques requires substantial muscular activation, yet due to the support of the machine, this muscular activation is possible for most participants, even those with substantial movement impairment.

2 Neurological Effects

All motion other than simple reflexes originates in the brain. The brain and the bodywork as a single integrated system, and many physical impairments have origins in the brain. In fact, improvement in any movement or action, from hitting a tennis ball to walking up the stairs results from refining and strengthening of the neural circuits which compute and execute these actions. The strengthening of these circuits comes about by repetition and adaptation in response to external feedback.
2.1 Neuromodulation
The drastic improvements observed after relatively short periods of use on the REVIVER exercise machine are most likely due to a process of neuromodulation. Neuromodulation is the alteration of nerve activity through targeted delivery of a stimulus, such as electrical stimulation or chemical agents, to specific neurological sites in the body. In the context of therapy, neuromodulation is primarily used as a means of inducing neuroplasticity, which is described in the following section. Neural activation is crucial for neuroplasticity to occur. For example, stem cells can replace damaged oligodendrocytes and re-insulate axons, but will only do so if the neuron is active, which is often not the case for damaged or disused tissue.
Neuromodulation for therapeutic purposes artificially activates natural intact pathways, and synchronises healthy neural tissue, leading to stronger connections and healthier neurons within these pathways (Kuo et al., 2014; Ridding and Ziemann, 2010). Neuromodulation can also enforce reconnection in malfunctioning tissue. Neuromodulation has been used effectively for Parkinson’s Disease patients, whereby an implantable pulse generator is implanted in areas identified via Magnetic Resonance Imaging as defective.
This therapy generally reduces motor symptoms and most patients can reduce medication (Benabid et al., 2009). Neuromodulation has also been used effectively for Epilepsy patients, where the vagus nerve is stimulated, and 30-50% of patients experience a reduction in seizure frequency and severity (Ben-Menachem, 2002). These therapies are quite invasive and require the implantation of a device.
Less invasive methods involve the application of a miniature electrode array to the tongue, a technique developed by the Neurorehabilitation group at the University of Wisconsin. This group applies the stimulation to the tongue at the same time as the patient carries out a movement task (Cranial Nerve, Non-Invasive Neuromodulation; CN-NINM). This combination is thought to be highly efficient at stimulating neuroplasticity (Danilov et al., 2007; Wildenberg et al., 2010). This technique yields large and rapid improvements in walking capabilities of traumatic brain injury and multiple sclerosis patients. We have documented equally large and rapid improvements in low-mobility elderly participants and in one case a cerebral palsy patient.
The REVIVER uses a very similar principle to CN-NINM, but is even less invasive. The stimulus is the periodic perturbation of the vestibular system via circular motion at a tilted angle. Such a stimulation does not occur in day-to-day life. Although the input stimulus is not electrical, the stimulus (motion) will generate an electrical impulse
