Virtual Reality for the Feet

NASA Challenge: Space Pioneering – Achieving Earth Independence

I wrote the following up for this contest. I was rejected for a rather weird reason. Click here to find out why? Don't Go to Mars with NASA

What is virtual reality for the feet?

Virtual reality for the feet is a method for simulating much of the earth bound sensory experience of resisting gravity. Devices embedded with servo- mechanisms can stimulate the proprioceptors in the feet. 

Why virtual reality for the feet?

Pressure to the feet has a myriad of effects. One of the most important functions is to stimulate the postural muscles. The postural muscles have an impact on the organization of the body. Postural muscle stimulation on the metabolic system and the tone of the musclo-`skeletal system. Further the impact extends to mental functions such as depression..

How could you achieve virtual reality for the feet?

Simple pressure to the feet could be achieved in a number of ways. Changeable shoe beds is the simplest way. Simply insert them into the boots.  Pressure enhancers could take the pressure from the sole of the shoe and amplify the signal into the sole of the foot. Both these techniques have their drawbacks. 

Or you can embed servo-mechanisms in the inside of the colonist's boot to apply light patterns of pressure to sole of the foot.This is the method I favor. Although more of a technical challenge it affords you greater flexibility in what could be provided to the colonists. 

When would you use virtual reality?

I can see using VR for the feet during the waking hours. It could be that a lessened amount of pressure is used during the sleep cycle. 

VR of the feet could be used on the long space flight as well as once on Mars.

Who would employ virtual reality for the feet?

The colonist would manage the VR for the feet. However, it could be setup for remote monitoring and control. There could be remote commands to stimulate the colonists if they needed it. Ot it could even be used to perform actions like revival. 

Note: These are attempts to answer questions from NASA.

How does humanity facilitate, enable, and incentivize the establishment of a second home on Mars?

Health is a major factor in any space colony. Knowing that steps have been taken to maintain the health of the colonists would help recruitment. improve the health of the colonist and may be a way to hack into the nervous system to solve various health problems.

Weightlessness and reduced gravitational fields can lead to bone loss and muscle destruction.  The loss of proprioceptive senses can lead to disorientation and perhaps certain psychological states such as anxiety. 

Physical Issues of Space Colonization

The space flight to Mars will take 260 days during that time the colonists will experience zero gravity and the detrimental effects arising from that environment. Add to that the fact that that the fact that the gravity on Mars is only about 38% of the surface gravity on Earth.   

The neural network of the body is profoundly impacted by the lack of weight bearing activities of standing, walking and moving while here on earth. The bedridden and wheel chair bound experience muscle weakness and bone loss.

Recent research on earth bound prolonged sitting has found the serious health effects of not weight bearing on frequent enough intervals. The impact on metabolic functions can lead to serious disorders such as diabetes, heart/lung and even Alzheimers as  examples. 

Could being in a zero gravity or reduced gravity environment lead to effects similar to the effects of prolonged sitting or uninterrupted sitting? It is hard to tell since the longest time an  astronaut was 437 days. A mission to Mars would entail a lot more time.

But the lack of stimulation to the postural muscles on an extended stay on Mars may be similar. A whole array of metabolic problems could  arise with an extended stay of Mars. 

However the differences could be to the musclo-skeletal system. While distortions to the earth bound prolonged sitter is complicated by gravity effecting their muscles the Mars colonists may be different issues. Still complicated by lack of full earth-like weight bearing muscles and bones could be distorted.   

Cognitive decline is associated with prolonged sitting. This could be a potentially dangerous situation on a space colony. 

What if there was a way to simulate locomotive activities thrby triggering the postural muscles which would reset the metabolic system, stimulating cognitive abilities, relieving some of the strains experienced by the musclo-skeletal system and building ground awareness for physical and psychological purposes. 

The bottom of the feet are a potential portal to access the nervous system. By applying the proprioceptive signals to the feet there could  be a way to simulate the actions of the postural muscles in an earth environment. 

Boots containing servomechanisms tuned to the locomotive needs of the colonists could be a way to deliver much needed sensory input. Pressure to the bottom of the feet can be programmed in a variety of ways to simulate the weight bearing of standing, walking or other movement patterns. 

Programs

Standing simulation for space flight

Increased standing sensory input in a diminished environment like Mars. 

Walking simulation in space.

Enhanced walking on the surface of Mars. 

Movement simulation during space flight.

Movement enhancements once on Mars. 

Relaxation modules.

Healing modules.

Virtual reality for the feet means that basic metabolic, musculo-skeletal and cognitive abilities can be addressed by simulating the proprioceptive messages that are routinely received in the everyday activities of walking, standing and other movements. 

It would facilitate preventative health measures that would protect the colonists from the serious consequences of the travel to Mars in zero-gravity. And it would it would address the issues arising from a diminished gravity environment. 

Keeping the body toned by stimulating the postural muscles would enable the colonists to function in a better fashion and keep their body's toned up.

How do we become and maintain Earth independence while living away from Earth?

Health is a critical element in living independently from the earth. The effects of zero gravity on the human body is well known. On Earth the devastating effects of prolonged sitting on our metabolism increases the risk of metabolic disorders such as diabetes. If you could even sent a supply of insulin with a crew of 4-6 crew members how long would a supply last. And since the onset of diabetes is an ongoing problem prevention seems to be key. 

And moving on to muscle-skeletal problems from a lack of tone would the colonists face greater challenges from not being able to perform the tasks necessary for survival. We need a system that can recreate the locomotive function of walking and moving in a field of gravity. 

How do we shape NASA’s human exploration program to minimize what we must bring with us and maximize the value and utility of what we bring, and augment it with what is already there?

There is some gravity on Mars. But what is missing is the demands of gravity on the locomotive system. If NASA would value the human foot and it's interplay with other bodily systems such as the the internal organs and the organs of balance it would make it feasible to establish a colony on Mars. The lack of proprioceptive signals and the cascading effects that will ensue may not be offset by a space ship full of pharmaceuticals. Stimulation of the foot triggers effects throughout the locomotive system. It may be more cost effective and feasible to create virtual  reality for the feet. It could simulate ground awareness and weight bearing with simple techniques. 

What specific capabilities and operations need to be developed, and how can specific natural resources on Mars be used to achieve true Earth independence?

Virtual reality for the feet would require programming of servo mechanisms that would simulate walking and other weight bearing activities, these servo mechanisms would be embedded in the boot. Pressure to the bottom of the feet could be patterned to trigger the maximum effect on the postural muscles and the vestibular apparatus even when the colonist wasn't upright. 

What should be put in place so that this initial foothold can thrive, instead of just surviving? 

If you expand on the initial thought that pressure to the bottom of the feet is critical to the colonist's health then creating many forms of sub stainable technology could be developed. A boot for instance that by applying pressure in Mars's gravity amps up the pressure signal could be developed. 

Just like a space suit is monitored for pressurization so to could the tone of the body be monitor for vagal tone by measuring heart rate variability. It would also be important to monitor vagal tone in order to keep inflammation in check. 

So a heart rate variability monitor would be essential to see proper tone is maintained. 

How do can we make sure that the sustainable systems/capabilities that we choose to implement will really provide the best holistic approach to Earth independence?

Testing the capabilities of a virtual reality system for the feet would be fairly straight forward. C-reactive protein tests and heart rate variability tests would show if the technologies developed are effective. 

What do you need to bring with you?

Boots that are programmable, or manually developed. Testing equipment such as a heart rate variability monitor ( i assume this would all ready by apart of the equipment on board) C-reactive protein test kits. 

What will be established once you get there?What will be established once you get there?

Testing stations and protocols for stimulating the proprioceptors.

How does it operate and how can it be tested now?

The basic principal is to apply the proprioceptive signal to the plantar aspect of the foot. It could be a pattern that simulates standing or walking. Or it could be a random pattern that would simulate the random patterns encountered in rough terrain. 

A series of servo mechanisms under the footbed of the shoe would be electronically triggered causing an increase of a slight pressure to the sole of the foot. 

Certain highly innervated areas such as the metatarso-phalangeal joint could be targeted for special attention. This area of the foot is activated in the beginning of the toe off stage in the end of the stance phase in walking. It communicates through the brain with the opposite foot to coordinate the swing phase with the stance phase. 

 Directional areas on the foot such as the cuboid bone which has also been referred to as the variable sensor can be target with movement sequences that simulate moving across rough terrain. This bone and it's movement has a global effect on the foot. It effects the subtalar joint which is involved in maintaining an upright position in human stance. It also effects the mid-tarsal joint  and the mid-foot joint which adjusts for terrain.  

If you want something a little further out you could have programs to perform revival, recovery from stroke, spinal cord injuries and other disorders. 

You could test it here on earth. Metabolic functions could be monitored to see the impact of plantar stimulation. Functional MRI's could be used to show the impact of various parts of the brain. Of interest would be the prefrontal cortex and the insular cortex. 

Why is it sustainable? Is there recycle, reuse? How long will it last?

It is sustainable because the technology is straight forward and should be simple to repair.

How is it intertwined with other systems/capabilities?

It would be integrated into other life support systems. 

How will it be maintained? 

It would require some electronics and repair of the servo units.

The New Reflexology: A Theoretical Summary Part 1

We wrote this orginally after our Paralysis Project in 1980. The percepts have really remained the same which is remarkable considering this was written 30 years ago. Editor
************************************************************************


 Our views of the foot and of reflexology have changed dramatically in the last two years (since 1980). This view suggests that the foot contributes to two basic integrated functions of the body, the stride mechanism and the survival mechanism. The foot is thus a participant in the body's interactions with both the external and internal worlds. The following is a summary of the logical extensions of this viewpoint, which lies at the heart of the “new” reflexology.

The Foot as a Sensory Organ

The foot is a sensory organ and a participant in the functioning of the body. Just as any other sensory organ, the foot has its specialty. It specializes in the information which makes locomotion possible. This information is in the form of proprioception, a type of sensation from joints, muscles, and tendons, communicating that which is not always consciously perceived about their position in relationship to the rest.

“This view suggests that the foot contributes to two basic integrated functions of the body, the stride mechanism and survival mechanism.” of the body, so that posture is maintained by reflex movement. This is the raw data used by the Central Nervous System to perceive the body's position in space so that it can be maintained or changed to make adjustments to the changing environment.


Additional thoughts from the editor. 
This concept is completely revolutionary in the sense that the foot takes on a very important function. the foot is not simply a conveyance but also detects pressure, stretch, movement, heat, cold and vibration. The foot is also key to "ground awareness". Indeed to stay upright in a field of gravity on two legs is indeed a difficult task. And the feet and it's communication links play a key role in preventing disaster.

Wobble Board, wobble balance board exercises.

I love my wobble board. I am not very good at it but I am getting better. 

My reaction to using the wobble board is a strange feeling in a way. I feel as though I have better grounding right after I leave the board. I am more aware of my feet. I also "feel" my body more. Why?

The body has sensors all around it which sense where parts of the body are even without looking. These sensors are called proprioceptors. -sportsinjuryclinic.net

These proprioceptors can get harmed do to accident or injury. The messages about body position become somewhat scrambled and so re-injuring  becomes a real possibility. A wobble board can retrain the senses of proprioception to retune the communications among body parts.  

Using a wobble board on a regular basis can help retrain the proprioceptors and improve coordination, hence preventing further injury.- sportsinjuryclinic.net

I like the exercises that are on this site. they start out slow and build your sightless sense of body position therefore improving the foot to brain link. Try these exercises. 

Reflexology can really help to reconnect the disconnected. The pressure that a reflexologist applies creates the same type of signal as a wobble board. While a reflexology session is quite relaxing wobble boarding can be a little more intense especially when you first start out. 

Oh yeah and take their advice on using a support like a chair to start out with. The last thing you want to do is injure those proprioceptors. 

These wobble board exercises are a lot of fun as they train your reflexes.

Is the foot a data storage device?

We were just talking this morning when an interesting question came up. Could you really call the foot a data storage device? I think you can. 

The foot does storage information. The body is a sum of it's parts including the feet. Information sharing goes on between all body parts. That alone implies stored memory. Past learned moves are stored as presets that respond to new demands. 

But the foot doesn't contain brain cells. So how does the foot send, receive, and store information. The proprioceptors have the capacity to send feedback through information received and signal changes in pressure, stretch and movement. 

What about storing information? Do proprioceptors have a memory capacity.  The proprioceptors don't exist within a vacuum. Rather they are pressure, stretch and movement sensors that coordinate their information with the brain and muscles. The proprioceptors work directly with the brain and rest of the nervous system to set the appropriate amount of tension within the body to respond to demands placed upon on it. This is referred to as movement intelligence and is where some of our overall memory takes place.    

But every footstep is not reinvented.  Rather it calls on preset stored information (data) to make that step possible. It has to be stored. 

What do you think? Is the foot a data storage devise?

The Body Has a Mind of Its Own

The Body Has a Mind of Its Own


I have been reading this book with great interest. The subtitle is interesting: How Body Maps in Your Brain Help You Do Almost Anything Better.

It is a self help book but I really like the discussion of the maps are brains contain that relate to our bodies. There is one body map called the "body schema". this map is "a felt sense based on the physical properties of your body." Another map "stems from learned attitudes about your body."

We know that there are maps of our body's schema. There are several schematics in several parts of the brain. Each and every body part is reflected in these blueprint like structures. These maps are both conscious and subconscious representations of our felt and perceived body. This book explains proprioception meaning "perception of one's own." It is how we sense where we are and how our bodies are configured. "These maps guide your body movements and expectations about those movements."

The authors blew my mind when they went on to talk about the important receptors on the bottom of the feet. They write about the decay to these receptors that occur over time and the impact on the aging process. They talk about some high tech solutions with faint vibrations to the bottom of the feet as was done by Dr. Collins at Boston University or more recently with the IShoe.

But according to the authors you don't need high tech to achieve the same results. You can simply walk on cobblestones like the Chinese have done for centuries. "The science of body maps explains how it works." And then they go on to explain it.

I have to say this book talks about what we have talked about for years. The reflexology charts are not without precedent. There are maps throughout the brain and yes, there are schemata throughout the body as well. This exists because we must map our existence from moment to moment just to survive. Every part of the body is a part of these maps.

This book makes me feel very positive about what we have said about the workings of reflexology.
