Isodynamics REVIVER Gets Genuine Results.png

REVIVER is a unique rehabilitation medical device designed to exercise, tone and condition the entire body in order to prevent, reduce or slow the progress of disability and disease.  

REVIVER's unique relaxed style of exercise therapy has application for helping improve symptoms of a wide range of neurological disorders including Parkinson's disease, Multiple Sclerosis, Cerebral Palsy, Autism and Stroke.

The unique motion device is designed to efficiently activate the natural conditioning and healing reactions that occur in the body when tilted against gravity, and moved in slow, radial wavelike motions  to stimulate reflexive muscle reactions  and beneficial gravitational epigenetic responses in different organs and tissues.

Over the past three years at Isodynamics REVIVER Clinic in Sydney Australia, exceptional outcomes have been reported by clients with a wide range of neurodegenerative impairments, in helping the following:

  • Return of mental and physical faculties

  • Increased strength, balance and mobility 

  • Relief of pain and disability

  • Improved quality of life and wellbeing 

Many of these benefits have been observed in the 22,000 patient therapy sessions already conducted at Isodynamics REVIVER Rehabilitation Clinic in Sydney, Australia.  REVIVER has been designed to produce beneficial results well beyond those achieved by existing exercise therapies. 

Isodynamics REVIVER has undertaken clinical trials for patients with Parkinson's disease and Atypical Parkinson's at Australia's Monash University and Alfred Hospital, supported through the Australian Government's Innovation Connection's program, which is delivered nationally by CSIRO.

The Story

Australian 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?” 

Solution: “Have a machine to do the moving for them. 

Allowing people of all ages and disabilities, to receive the full medicinal benefits of exercise.”

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

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

After using the REVIVER device, some patients with differing physical and neurological impairments,
are experiencing regaining their ability to:


·Walk ·Talk ·Balance 
·Smell ·Taste ·Smile ·Swim 

·Clap hands ·Write

·Unfreeze ·Walk Backwards 


As well as experiencing reduced anxiety and pain throughout their body, often at times within minutes of using the REVIVER device*.


Scientific research and clinical trials to better understand and validate these results from the Isodynamics REVIVER clinic in Sydney are already underway.

Neuromuscular Rehabilitation Clinic

Sydney Australia

The REVIVER is a device that reduces the amount of effort required to exercise,
by using the body's balancing system and gravity to stimulate the nervous system and activate abilities that may have become dormant.


The REVIVER is designed to achieve this for a wide range of people across all ages, abilities and disabilities with a minimum amount of time and effort in a safe user-friendly manner whilst delivering beneficial results.


This newly discovered treatment option has been realized through use of the REVIVER's slow, radial wave-like motions and gravity, acting on the body's reflex balancing system. 


REVIVER devices are a unique treatment option for clients that need the benefits of exercise to improve strength, balance and mobility, even if the patient is only capable of laying, sitting or standing, due to pain or disability.


These devices enable the benefits of exercise to occur without the normal stress or impact associated with traditional exercise therapies.

REVIVER delivers exercise benefits well beyond current methods of exercise therapy.  

At present, REVIVER therapy is only available at the Isodynamics Neuromuscular Rehabilitation Clinic in Sydney Australia. Our clinic caters for a wide range of neuromuscular patients including those with Parkinson's disease.  


Bookings for consultation and therapy sessions are billed in half-hour increments at industry rates.
The unique REVIVER therapy sessions are supervised and conducted by university-qualified Physiotherapists and Exercise Physiologists (EP's), experienced in catering for individual patient needs.

All our EPs are accredited members of Exercise & Sports Science Australia (ESSA).

REVIVER: Scientific Principles and Future Research 

Stimulation of Reflexes to Promote Recovery 


The REVIVER effectively tilts the body “off-axis” to gravity in slow, passive and radial wavelike motions through 360 degrees.

The unique REVIVER motions rapidly activate the self-righting reflex by recruiting balance and sensory reflex signalling pathways within the spinal cord that are important for coordinating reflex-induced tone in the trunk and limb muscles required to maintain balance (1).

Activation of the self-righting reflex by the REVIVER motion stimulates neural signalling pathways that control movement and efficiently promotes a coordinated activation of large and small muscle groups throughout the body, that may have become weak through lack of use due to advanced age, disability or disease.

The REVIVER device technology is unique, as to our knowledge there are currently no published research studies of inducing reflexive muscular contractions in response to “off axis” gravity stimulation to treat patients with neurological disorders.

The Role of Neuroplasticity in Supporting Recovery 


The ability to efficiently increase blood flow, tone and coordinated activity of multiple muscle groups throughout the body is undoubtedly playing a significant role in the recovery of strength, balance and mobility reported by patients treated at the Isodynamics Sydney pilot clinic. 

However, the ability of REVIVER treatment to also activate dormant neural signalling pathways or promote the formation of new beneficial neural circuits in the brain and spinal cord (2),(3), a process known as “neuroplasticity”, may also contribute to the recovery of both physical and mental faculties reported by patients.

Through robustly stimulating coordinated activation of the vestibular “balance” system and multiple muscle groups throughout the body, REVIVER treatment has the potential to stimulate the nervous system by a process called “neuromodulation” that is known to drive neuroplasticity (4),(5).

Promoting beneficial neuroplasticity is widely accepted as a promising therapeutic approach for neurological disorders such as Parkinson’s disease (6), stroke (7), cerebral palsy (8),(9), and brain (4) and spinal cord injury (10) and is therefore likely again contributing to the recovery reported by patients with these disorders after REVIVER treatment at the Sydney clinic. 

REVIVER, Gravity and Epigenetics


Epigenetics can be defined as changes in cells and organs of the body caused by environmental stimuli that can modify gene expression without directly altering the genetic code itself (11),(12).

Gravity has been shown to promote epigenetic adaptions in cells and organs of plants and animals (13). Scientific studies of the effects of long-term space travel have in large part driven research into the effects of gravity on the nervous system (14) and other tissues of the body (15). Notably, changes in gravity can alter growth of axons (nerve fibres) (16), a key element of neuroplasticity.

At Isodynamics we consider the REVIVER to be a device for generating beneficial “epigenetic” effects of gravity in humans.

Future laboratory and clinic-based research will determine the epigenetic cellular adaptions to the radial motion “off axis” gravity stimuli provided by the REVIVER motion on the nervous system and other organs of the body.

The Isodynamics REVIVER Devices

REVIVER was designed and created to use our body’s response to gravity to naturally and efficiently stimulate and condition nervous system pathways, muscles, organs and cells throughout the body that may have become weakened or dormant due to age, disability and disease. 

All three REVIVER devices have been listed on the Australian Register of Therapeutic Goods as a Class 1 Medical Device.

REVIVER treatment at the Sydney clinic has achieved results in improving strength, balance and mobility in a wide range of patients who were previously not able to achieve similar degrees of recovery from conventional exercise rehab programs - including patients with neuromuscular diseases and conditions such as Parkinson's disease, Stroke, Multiple Sclerosis and other impairments for which exercise is known to be beneficial.


The REVIVER devices have been undergoing testing and development over the past three years at our pilot clinic in Sydney, Australia. Analysis of client case studies at the pilot clinic have been promising, with an assessment of Parkinson’s disease users indicating an average 22% (p<1x10-5; N=15, unpublished observations) increase in mobility (reduction in timed up and go times; TUG) over an average period of 26 days of REVIVER treatment. These results have warranted an Australian Government's Innovation Connection's program sponsored phase 1 clinical trial, to assess REVIVER treatment of the symptoms of Parkinson’s disease conducted by Monash University and the Alfred Hospital in Melbourne, Australia.


REVIVER users at the Sydney clinic have also reported improved balance, muscle tone, and the capacity to return to previously desisted activities such as walking unassisted, climbing stairs and swimming. Several patients who reported they had lost the ability to walk unassisted prior to treatment, regained this ability after 2-10 weeks of REVIVER therapy.


To our knowledge no other rehabilitation device has the capacity to drive “off axis” gravitational stimulation and conditioning of the whole body, and thus provide the range of benefits observed in patients after REVIVER therapy at the Sydney clinic.

REVIVER works for a wide range of people, providing benefits for those with disabilities as well as elite athletes, by using gravity to effectively stimulate and condition the nervous system, large and small muscle groups, and many other tissues throughout the body, with a single user-friendly motion.
