Assist with developmental injury, brain injury, spinal cord and numerous other injuries. Therapy and physical conditioning for specific problems where persons are unable to use traditional systems or methods of rehabilitation.

​Stimulates the brain cells helping to recuperate some brain functions.


Cuts down on exercise time requirements for fitness, muscle, and bone strength, as well as kick-starting your metabolism.


Increases gravity with low impact on entire body system of muscles and joints to provide a total body workout, all while comfortably lying on a spinning centrifuge.


Restores muscle and bone loss by weight loading the entire body and especially the lower extremities drawing blood toward the feet which stimulates the heart and blood circulation.


Inactive persons are deprived of gravity, similar to astronauts, which changes their metabolism, with fat accumulating to replace lost muscle. The reduced mobility and absorption of the gut alters the basic nutritive value of the foods we eat.


The right type of exercise is important and gravity combined with the right type of exercise makes it more effective.  It is the totality of gravity’s effect on the body that holds the key and knowing which exercises use gravity best.

Speed and gravitational load can be variable and intermittent and adjusted according to physical condition and needs of user.  Acceleration & deceleration best.

  • Improves coordination and balance in elderly people who have lost it. Reduces   exercise time-Get fit without moving a muscle

  • Increases muscles and reduces fat-with increased gravity there is a metabolic shift toward a leaner state. Whole body weight training -Stimulates metabolism

  • Forces muscles to contract-increases your weight without increasing your mass which stimulates bone strength   

  • Increases cardiovascular activity-Improves blood pressure regulation

  • Positive impact on musculoskeletal function-Doubles gravitational load on body

  • Muscle toning and building bone strength targets stabilizer & mobilizer muscle systems to help maintain posture

  • Head out and feet in could also be used intermittently to mimic alternating posture to provide stimulation of the inner ear.

  • Mild longitudinal stretching provides spinal cord decompression for bulging discs

  • Lymph drainage


Primary benefits of centrifuge use consist of cardiovascular health, rehabilitation and fitness:  References at end.

Microgravity (10¯⁵ gravity) experienced by astronauts in space, and the reduced effect of gravity on Earth by being bedridden and inactive, sedentary or aging, have demonstrated similar negative effects on the human body¹. This is especially true for aging persons. Those who are bedridden or sit much of the day, though surrounded by gravity (1Gz) in fact use gravity less because they move less. In particular, they change posture less often, sit almost all day, and do not stand up as often throughout the day. This leads to difficulties in normal mobility starting with problems using the toilet unassisted and in maintaining independence in general. The physiological changes include every system and every cell in the body. With respect to the cardiovascular system, reduced gravity or its use, is characterized by diminished cardiac function and mass²׳³.


This is the result of transient diuresis and natriuresis, a 2-4% reduced body mass, and a 6-15% lower plasma volume (PV)⁴. It is followed by decreased heart size, cardiac stiffening, reduced filling, stroke volume (the amount of blood pumped around the body), cardiac output and aerobic capacity. Aerobic capacity, the amount of oxygen taken in to supply the brain and other organs can decrease by 25% within 4 days of bed rest⁵. The sensitivity of the cardiac-carotid baroreflex in the neck that regulates blood pressure loses its sensitivity within 10-12 days of lying down continuously resulting in orthostatic hypotension (OH), (the tendency to faint on standing up) ⁶. It is not only the heart muscle that is reduced in bed rest and aging, but a weakening in the endothelium lining of blood vessels reduces their ability to constrict in response to the smaller volume as they try to keep the blood flowing⁷. Reduced circulation increases the risk of forming clots and stroke.

Providing passive stimulation to the cardiovascular system that mimics standing up often provides the needed answer. Exposure to 1Gz is equivalent to standing up while lying down. The elderly, those in rehabilitation, as well as those who because of disability, who do not or cannot stand up or stand up often by themselves, are the most likely to benefit from 1Gz centrifugation with all its associated body responses. It can restore to normal all aspects of this cardiovascular response to aging, sedentary lifestyle and disability. These include but are not limited to stronger heart muscle, increased heart rate, PV and stroke volume (more blood volume ejected with each contraction), the ability to pump blood up to the brain to maintain adequate oxygen and fuel for mental function, as well as movement of muscles with all the associated metabolic functions that rely on contracting muscles and independence in general.  

To date, centrifuges have been used for testing the tolerance of the human body to G forces in fighter pilots and in astronauts during re-entry and recovery from space missions. Reduced tolerance means an inability to regulate blood pressure resulting in fainting.

Centrifuges have also been used for over 50 years in research on the chronic exposure of experimental animals to levels greater than +1GZ and up to 4.5 Gz.  Occasionally they have been used in human volunteers at levels of 1-4Gz for research purposes to determine both the benefits and adverse effects of such levels. Higher than 3Gz tolerance (characterized by black-out or fainting) is used in research and fighter pilot selection and training in the military. 

There are only 13 short radius centrifuges in the world. Their design and support costs can run into the millions of dollars.   This has discouraged the transfer of this beneficial technology to the aged and for use during rehabilitation and health maintenance. In none of these studies have adverse effects been described in healthy humans though some nausea may be experienced at first at levels greater than 1Gz with faster rotation.

At the lower +Gz levels, (1-2Gz where 1Gz is used to mimic standing up on Earth) as proposed here, we have developed a simple, safe, low cost, personal centrifuge system for use by individuals in rehabilitation in elderly, disabled or inactive individuals to restore and maintain health and fitness.

Such a controlled low level of hypergravity usually at 1GZ, can benefit persons of all ages, maintain or restore their mobility and help lower their routine health care costs.  Should higher G levels be desired, our centrifuge may easily be adapted to reach levels of or near +2Gz.
Centrifugation by virtue of rotation in the horizontal axis with head in the center and feet out, provides at least three major sources of stimulation to the body:

  1. Whole Body Weight Training where increased body load by gravity pulling the body weight in the head to toe direction, much like standing up does, stimulates muscle and bone.

  2. By pulling blood to the feet, heart pumping is stimulated (increasing stroke volume and cardiac output), to compensate the redistribution of blood. General circulation is increased as blood is shifted from the feet back up to the head and brain.

  3. Rotation stimulates the inner ear (vestibular nervous system) that controls balance and coordination. It is also now known that it stimulates blood pressure, muscle and bone, fat and glucose metabolism and insulin sensitivity. The level of Gravity sensed at the feet for instance depends on revolutions per minute and the diameter of the centrifuge.
    In addition, 

  4. the Mechanical Action of loading and rotation stimulate through a push/pull action every cell directly, primarily skin, fluids, muscle, ligaments, tendons and bone. The process is known as mechano-transduction where mechanical forces are translated into biochemical reactions. For example, the stimulation of collagen synthesis can be triggered by pulling on skin cells and ligaments.Our innovative ‘personal’ centrifuge system, with proven benefits from the space program, is fully developed, safe, market-ready and can be manufactured at a cost comparable to medical rehabilitation treadmills.This new invention, appealing in its simplicity, is a pioneering system primarily for the rehabilitation and aging market on Earth. It will be the first centrifuge product to market to the general public for its gravity-enhancing health and fitness benefits.

The primary benefits demonstrated in humans that would be expected by using our centrifuge on a regular basis, consist of cardiovascular health, rehabilitation and fitness. 

  • Centrifugation improves the performance of the heart⁸׳ ⁹. 

  • Restores to normal plasma volume, heart rate, stroke volume. 

  • It restores the sensitivity of baroreflexes thereby preventing possible falls from sudden drops in BP.⁸

  • Centrifugation is most effective when applied intermittently eg. 30 minutes 2Gz/2x a day or 30 min divided into 6 x5minibouts at 1Gz/1x per day ¹⁰.

  • Centrifugation increases energy and mobility by restoring higher aerobic capacity (VO2max) ¹¹׳¹².

  • Centrifugation prevents falls in older persons by improving balance and gait sensors in the vestibular system¹¹׳¹⁴. 

  • Centrifugation adds to the benefits of exercise restoring aerobic capacity (VO2max) further ¹²׳¹⁴.


A large meta-analysis of all human centrifugation (aka artificial gravity) studies, concluded that to date solid documentation supports cardiovascular effects as the major benefits of centrifugation¹⁴.  Similar studies for muscle, bone or metabolism are encouraging. However, they have not been done for sufficient durations in humans¹⁴ to confirm metabolic bone and other benefits.

Extensive animal research and some human research have indicated, but not confirmed in humans, that continuous rather than intermittent centrifugation/Artificial Gravity  

  • Improves muscle strength, mass and power and increases collagen synthesis through its whole body-weight training effect¹⁵.

  • Increases body mass, composition and food intake¹⁶, increases glucose uptake and metabolism by muscle¹⁷, reduces insulin resistance preventing a pre-diabetic state¹⁷ and increases fat metabolism accelerating weight loss¹⁸׳¹⁶. 

  • Improves cerebral oxygenation and circulation that may aid in brain injury conditions, impaired cognition or dementia¹⁹.

  • Increases testosterone production in rhesus monkeys but has not yet been shown in humans²⁰.
