Michael Tetley presents an anthropological and zoological approach to the treatment of low back and joint pain, based on instinctive sleeping and resting postures:
If you are a medical professional and have been trained in a “civilised” country you probably know next to nothing about the primate Homo sapiens and how they survive in the wild. You probably do not know that nature has provided an automatic manipulator to correct most spinal and peripheral joint lesions in primates. In common with millions of other so called civilised people you suffer unnecessarily from musculoskeletal problems and are discouraged about how to treat the exponential rise in low back pain throughout the developed world. Humans are one of 200 species of primates.1 All primates suffer from musculoskeletal problems; nature, recognising this fact, has given primates a way to correct them.
The study of animals in the wild has been a lifelong pursuit. I grew up with tribal people and in 1953-4 commanded a platoon of African soldiers from nine tribes, who taught me to sleep on my side without a pillow so that I could listen out for danger with both ears. I have organised over 14 expeditions all over the world to meet native peoples and study their sleeping and resting postures. They all adopted similar postures and exhibited few musculoskeletal problems. I must emphasise that this is not a comparison of genes or races but of lifestyles. I tried to carry out surveys to collect evidence but they were meaningless, as tribespeople give you the answer they think you want. They often object to having their photographs taken, so I have demonstrated the postures.
Tetley was born in Kenya, where he encountered much worse Mau-Mauing than what Tom Wolfe described:
Mike, who was born and raised in Kenya speaking its native language Swahili, was conscripted to command indigenous troops in the King’s African Rifles as unrest began to spread throughout his homeland.
It was after Mau Mau militants ambushed a police truck that a battle erupted between the rivals.
A clash Mike so vividly recalls as it marked the last time he could appreciate the gift of sight before it was lost.
Remembering the battle, Mike said: “One of the Mau Mau threw a grenade at me and it landed by my foot. I jumped away from it and threw myself on the ground hoping that when it went off I wouldn’t get hit.
“The next thing I remember I was running flat out and I got a bullet in my right ear which came out of my right eye.
“My dad always said I didn’t have anything between my ears and now he’s got definite proof.
“The next thing I remember I fell over and as I picked myself up everything went black. I sat down and I can’t remember much more than that — not in a logical sense anyway.”
Dissatisfied with blasting their victim with a rifle — nearly killing him — the Mau Mau rebels returned armed with machetes to cut up Mike, who lay helpless on the ground nursing his wound. Powerless to defend himself, Mike has always owed his survival to an ally soldier, Reguton — with whom he still has regular contact — who shot dead the seven rebels.
“I was on the ground and they came forward with guns and knives and they tried to cut me up,” he said “Reguton had his gun and shot them and killed them. He killed seven of them from 25 yards — that’s very good shooting, particularly when you’ve only got 28 bullets in a magazine. From 25 yards he would have had three bullets for each person until they were on top of him — I’m very indebted to him.”
For Mike, vivid scenes of massacre and torture remain poignant in his memory. Images of bloodshed to which Mike was repeatedly exposed before he lost his sight have proved impossible to dispel from his mind.
More than 1,800 Kenyan civilians are known to have been murdered by the Mau Mau. Many of the murders of which they were guilty were brutal in the extreme and Mike recalled just one of the savage killings.
“I was walking back to my tent and there was a 12-year-old girl in the middle of the road with her throat cut. There was a note next to her which read ‘We’re not frightened of you, we’ll take you on, the army and the police. It was signed Corporal Kanwemba of the Mau Mau.”
Mike was transferred to a military hospital in England after the attack where he received the devastating news that he would never see again.
He enrolled in a physiotherapy course with the Royal National Institute for the Blind (RNIB) — which brings us back to his paper:
Figure 1 shows a mountain gorilla lying on the ground on his side without a pillow — a position in which I have also seen chimpanzees and gibbons sleeping — and a Kenya African in a similar position on a palm leaf mattress on a concrete floor. Note how he uses his laterally rotated arm as a pillow and can listen out for danger with both ears.
When lying on one side you do not even need the arm as a pillow: when the lower shoulder is fully hunched, the neck is completely supported. I think the neck should deviate towards the ground as gravity then shuts the mouth, preventing insects from entering, and a little traction is applied to the cervical spine (fig 2, top). When the head is down, the vertebrae are stretched between two anchors and every time the ribs move through breathing the tension is increased, the vertebrae realign themselves, and the movement keeps the joints lubricated. Current thinking is to keep the spine straight by use of a pillow. Has anyone ever seen a gorilla shinning up a tree with a pillow? Note also the plantar flexed foot. A dorsiflexed foot rotates the knee and alters the Q angle (between the resultant pull of the quadriceps muscle and the patella tendon), producing uneven wear and, in time, pain.
Tribal people do not like lying on the ground in the recovery position while wearing no clothes as the penis dangles in the dust and can get bitten by insects. When the legs are in the reverse recovery position (fig 2, bottom), the penis lies on the lower thigh and is protected. In this position the Achilles tendon of the leading foot can be inserted in the gap between the big toe and the first lesser toe to help correct a bunion.
When sleeping in the open in very cold climates and when the ground is wet, humans often resort to sleeping on their shins, like the Tibetan caravaneers photographed by Peter, Prince of Greece and Denmark, in 1938 (fig 3). Nature has not covered the anterior border of the tibia and the medial border of the ulna with muscle, so in this position there is only skin and bone in contact with the cold ground and heat loss is reduced. The body is also folded to conserve heat; both ears can listen for danger, be it lion or terrorist; and when the head is down gravity shuts the mouth and it is impossible to snore.
Figure 4 shows the “lookout posture,” another position using the arm as a pillow to reset shoulder, elbow, and wrist: accessory joint movement is regained because the weight of the head resting on the arm is at right angles to the line of movement, producing a lateral glide. I have seen Howler monkeys using this position in Costa Rica
Quadrupedal lying (fig 5) is ideal for stretching collagen fibre throughout the body. In the penis protect position, with the pelvis locked, the spine is rotated and flexed. With the elbows out sideways and the chest on the ground, many spinal lesions can be corrected gently using nature’s automatic manipulator. Animals are clever because they use the radiant heat from the sun to encourage relaxation of their muscles when they adopt this posture. In this photograph note that the dog’s sternum is in full contact with the ground but that of the human is not: this can be easily corrected by rotating the right arm medially to lower the sternum. It has been noted that guide dogs working in towns breathe the same pollutants as humans yet do not have asthma. Could this be because when they lie on their chests the kickback from the upper ribs keeps the corresponding vertebrae mobile, allowing the sympathetic system to work efficiently?
Arabs in the Sahara will sit in the position shown in figure 6 for hours and it keeps the forefoot aligned on the hindfoot, as the ischia rest directly on the calcanea and the feet point straight backwards. People who sit like this do not seem to get much osteoarthritis in their knees in old age. Cross legged sitting prevents arthritic hips. A flying doctor from Kenya remarked to me that over the years as local tribesmen became more civilised he more often saw arthritis of hips and knees.
The full squat, with the heels on the ground (fig 7) resets the sacroiliac joints; takes hips, knees and ankles through the full range; and can be very useful in treating backs. To start with, some Westerners have to hold on to a door frame.
Largely anecdotal evidence has been collected by “old timers” for over 50 years from non-Western societies that low back pain and joint stiffness is markedly reduced by adopting natural sleeping and resting postures. This observation must be recorded to allow further research in this direction as these primitive societies no longer exist and the great apes living in the wild are heading for extinction. All we have to do is to be good primates and use these preventive techniques.
