| 7. CORRECTING YOUR 
            POSTURE: Yoga, the Alexander Method of posture correction, Osteopathy and 
            Chiropractics can help you to improve your posture. The first two 
            involve learning to use your body in a better way, while the last 
            two depend on external manipulation.  Let us however look at the problem from an Engineering 
            perspective. There are 206 bones in the human body and more than 600 
            muscles; these interrelate with one other in complex ways. Clearly, 
            posture cannot be corrected the way in which you would repair a 
            motorcar. Since the problem is mechanically very complex it is 
            necessary to evolve simple principles which will help the body to 
            naturally go back to its correct alignment.  It is useful to keep in mind, as we attempt to correct our 
            posture that all humans have precisely the same number of bones and 
            muscles in their bodies. If one person moves more gracefully than 
            another, or he looks better proportioned, it may not all be due to 
            any major difference of equipment, but rather the way in which the 
            equipment is used.  7.1 STRATEGY FOR CORRECTING POSTURE: 
              
              
                |  | Fig 7. Correcting posture has three important aspects:

                    MENTAL ASPECT 
                    BEHAVIORAL ASPECT  |  The Mechanical aspect can be split as follows:

            them:

                    BALANCING POSTURE  |  |  7.2 PHYSICAL ENVIRONMENT:  
              CLOTHING 
              FOOTWEAR 
              CHAIR 
              SOFT SURFACES 
              TAKING EXERCISE  7.2.1 CLOTHING …………… And the Lord God called unto Adam, and said unto him, where art 
            thou? And he said, I heard thy voice in the garden, and I was 
            afraid, because I was naked; and I hid myself. And he said, Who told 
            thee that thou was naked? Hast thou eaten of the tree, whereof I 
            commanded thee that thou shouldest not eat?  ……….. The Bible, Genesis 3:9,10,11  The instinct to cover the naked body has prompted all cultures to 
            tie something or the other around the waist. Humans (Proto-humans) 
            could have started to tie things around their waist as long as 2 
            Million years ago! Tying anything around the waist will however 
            prevent proper functioning of the stomach muscles. For girls and 
            women therefore the best items of wear are frocks and gowns. Skirts 
            and saris are not advisable unless you can find some way to suspend 
            them from the shoulders. For boys and men, shorts and trousers, 
            which are loose around the waist and suspended from the shoulders, 
            are best. Anything tied around the waist, even loosely, like dhoti 
            and pyjama will create problems. Pyjamas should also be suspended 
            using shoulder straps. Modern V type underwear, with soft elastic 
            that grip the pelvic bone are OK. The important thing to remember is 
            that we are not born with our clothes on and no animal other than 
            ourselves wear clothes. Clothing should not inhibit movement of the 
            body. If the musculoskeletal system is inhibited in any way, at any 
            location, it will upset the postural balance of the whole body.  7.2.2 FOOTWEAR ………… Improper footwear will cause major problems. The best thing to 
            wear is leather slippers with thin soles, in which the soles, both 
            where they come in contact with the feet and where they come in 
            contact with the ground are perfectly flat. We will find invariably 
            that slippers available in the market have heels. It is important to 
            have the heels removed. It is more difficult to find suitable shoes: 
            shoes may severely restrict freedom of movement of the feet and thus 
            affect posture. Hawaii slippers provide tremendous freedom of 
            movement, hence they are recommended – a firm material such as 
            leather is however better than rubber which provides cushioning. 
            Proper gait is a complex wave like motion starting at the feet. 
            Improper footwear will alter this gait.  7.2.3 CHAIR ……….. 
             The thighbones are attached to the pelvic bone by means of ball 
            joints and actuated by very complex arrangement of muscles. It is 
            very important to sit in such a way that the freedom of movement at 
            this joint is not seriously compromised. When sitting in standard 
            chairs you are effectively sitting on the muscles which move the 
            thighs, thus severely restricting their freedom of movement, Fig 8a. 
            The problem can be solved by sitting on chairs and benches, which 
            are lower, or by using footrests, Fig 8b. It is better to sit on 
            hard surfaces rather than on cushioned surfaces.  
              
              
                |  |  
                | Fig 8a: In a standard chair the thighs make 
                  intimate contact with the chair, inhibiting free movement of 
                  muscles. Fig 8b: By limiting contact of the thighs with the 
                  chair the legs can be made more active and postural balance 
                  can be achieved. Fig 8c: Soft cushions will prevent free 
                  movement of muscles. |  7.2.4 SOFT SURFACES …………..  Our ideas about comfort are closely associated with soft 
            surfaces. Excessively cushioned surfaces on chairs, shoes, bed, 
            pillows etc. however will inhibit use of muscles and prevent them 
            from achieving postural balance (Fig 8c). Use of hard or firm 
            surfaces will help to keep muscles active and thus promote good 
            health.  7.2.5 TAKING EXERCISE ………..  Taking exercise and improving posture are basically incompatible. 
            Small children and animals do not take exercise, they play, they are 
            active and maintain superb postural balance: they are much healthier 
            than human adults. When exercise is heavy it is impossible to ensure 
            that all the muscles will be exercised uniformly: because of this, 
            different persons doing the same exercise can end up with markedly 
            different results. Walking is perhaps the best physical activity to 
            keep us fit; it should not be viewed as an exercise, rather it 
            should be interwoven in the fabric of our daily life. Exercising 
            with anything tied around the waist and while wearing faulty 
            footwear will distort posture. (When exercising or doing heavy 
            physical work we should also try to be in present space – see 
            below) 
              
              
                | 
                    
                    
                      | SCIENTIFIC BASIS FOR 
                        TAKING EXERCISE It is difficult to establish a scientific basis for 
                        taking exercise, especially heavy exercise. From an 
                        engineering perspective, if a structure is distorted 
                        (Fig 6), it is necessary to remove the distortion. You 
                        never load a deformed structure! Doing exercise with clothing and footwear, which are 
                        likely to distort the muskuloskeletal system, is equally 
                        questionable. In Greece, where the Olympics first took 
                        place, participants did not wear clothes! (Women were 
                        not invited to these events.) Perhaps, they understood 
                        human posture better than we 
                  do.
 |  |  7.3 MENTAL ASPECT  There are 206 bones in the human body and more than 600 muscles, 
            it is impossible for us to figure out consciously how to hold them 
            all in a proper way. Only the subconscious mind can accomplish this 
            difficult task. To improve our posture therefore we have to 
            periodically move into PRESENT SPACE. Using this principle we can 
            begin to understand why small children and animals naturally 
            maintain good posture, and why for human adults it presents a 
            difficult task. Moving into present space is simply seeing things 
            around you sharply and clearly…  The principle can be explained by a simple experiment, which does 
            not need any tools. Become fully conscious of your immediate 
            surroundings by looking at things sharply and clearly – the 
            beautiful painting on the wall, the floral designs on the curtains, 
            the walls of the room, the books on the table, the beautiful green 
            of the lawn outside. Don’t strain to see any particular object – 
            keep the eyes relaxed by moving gently from one object to another. 
             Next, while looking clearly at external objects think of 
            something – anything. Perhaps the pleasant holiday you spent last 
            summer. Or try to conjure your wife’s / husband’s face. What 
            happens? When I persuaded a few friends to try this experiment, not 
            one was able to think in any way when he was fully focused on his 
            surroundings – it is in effect an animal state, of becoming one with 
            the environment. If you try to force yourself to think while holding 
            on to the images of your surroundings, the eyeballs are put under 
            severe strain as they try simultaneously to turn outwards (towards 
            the surroundings), and inwards (towards a thought or mental image). 
            Hence we can form a principle:  YOU CAN’T BE FULLY CONSCIOUS OF YOUR SURROUNDINGS AND 
            SIMULTANEOUSLY ENGAGE IN A PROCESS OF THOUGHT. 
              
              
                |  | Fig 9: Experience tells us that animals can 
                  occupy only Present Space, while Humans can occupy Present 
                  Space, Thought Space or a Space 
            in-between. 
 |  The concept is explored further in Fig 9. The space in which the 
            brain can wander (when the subject is awake and alert) can be 
            divided into two parts, Present Space and Thought Space – the two 
            separated by a barrier. Observations of animals suggest that they 
            are always alert to what is happening around them, they are never 
            ‘lost in thought’ in the human sense. Hence it can reasonably be 
            assumed that they can occupy only Present Space – the construction 
            of their brain does not permit them to do otherwise. Human beings, 
            on the other hand, can occupy Present Space, Thought Space or a 
            Space that is in-between the two. For occupying an intermediate 
            state a price has to be paid in the form of increased physical 
            tension, which is first felt in the eye-balls and from there, the 
            rest of the body.  In the Alexander method of posture correction two complementary 
            principles are used which achieve the objective of bringing the mind 
            to present space in different ways. The first is the principle of 
            INHIBITION in which you are advised to inhibit your movements, that 
            is, let us say you are reaching for a book, you should deliberately 
            pause for a fraction of a second before you start your movement. The 
            pause will make you focus on the task at hand.  The second principle is AVOIDING AN END GAINING APPROACH. Let us 
            say you are driving a car, you are late and in a hurry to reach the 
            railway station. If you keep worrying about missing the train, your 
            muscular coordination will automatically become faulty. On the other 
            hand if you say to yourself OK it does not matter whether I catch 
            the train or not, your muscular co-ordination will improve, you will 
            be less likely to involve yourself in an accident, you will enjoy 
            your drive to the station and probably reach there sooner.  Good posture can be defined only when we are in present space. 
            When we are thinking our posture will automatically become faulty! 
            It is important to move into present space at periodic intervals to 
            keep us healthy and also to improve our mental functioning. Both, 
            the human body and mind work better in the subconscious state.

                      | IMPROVING PERSONAL 
                        RELATIONS  Moving into present space will help improve our 
                        personal relations. In this state we can make eye 
                        contact, and judgment of others, which vitiate many 
                        relationships will be temporarily 
                    suspended. |  |  7.4 BALANCING POSTURE 
              
              
                |  |  
                | Fig 10: A balanced system is easy to oscillate 
                  too and fro. |  Balancing posture is very similar to balancing weights using a 
            weighing balance, Fig 10. Discovering how the large number of bones 
            and muscles in the body are linked is however not easy. To balance 
            posture we must not lock our bodies externally or internally.  Crossing one leg over the other when sitting down, crossing hands 
            over the chest and passing the weight of the upper body through the 
            arms when sitting next to a table are all examples of external 
            locking of the musculoskeletal system. The body should be held 
            symmetrical and the weight of the body should be passed to the 
            ground uniformly on both the legs – the woman in the plaque fixed on 
            the Voyager spacecraft is striking an attractive pose, but 
            supporting the weight of the body mainly on one leg is a form of 
            external locking, which provides poor postural balance. Even using 
            the backrest when sitting in a chair, which will prevent proper use 
            of a large number of muscle groups, can be conceived as external 
            locking.  Internal locking is when joints are held at their extreme 
            position. For instance the knees should always be slightly flexed to 
            keep all the muscles active. If the knees are moved to an extreme 
            position many muscles will have no work to do. Just as a shark must 
            swim continuously in order to breathe, so also, we must balance our 
            posture continuously to maintain the shape of the body.  When balancing our posture we have to minutely adjust the 
            musculo-skeletal system to get a feeling of strength and flexibility 
            over the whole length of the body. We must rediscover the contour of 
            the spine and we must be able to flex it, somewhat the way in which 
            a snake slithers on the ground. We must attempt to poise the head 
            gracefully and strongly over the spine. (Postural balance is easier 
            to feel out early in the morning in bed, after a good night’s sleep; 
            make sure your pillow elevates the head by no more than 2.5 cm, so 
            that the natural curvature of the spine is maintained). The girl in 
            (Fig 11) has good postural balance, observe that she is very much in 
            present space.  
              
              
                |  | Fig 11: Child demonstrating good postural 
                  balance. (From The Alexander Principle by Dr. Wilfred Barlow). 
 |  Balance is a fundamental concept in Engineering. Many stationary 
            systems and practically all systems that move must be balanced to 
            function properly. The concept of balance is important for the 
            following reasons:  
              Posture can only be corrected by trial and error. By keeping 
              this concept in mind we can avoid going dramatically wrong. 
              It helps explain why 99% of adults will have postural faults. 
              A concept of balance (lacking in our environment and social 
              interactions) is required to integrate the musculoskeletal system. 
              The concept of balance provides a suitable guideline for the 
              science of ergonomics. The dress we wear, the footwear and the 
              design of our physical environment must ensure that we are able at 
              all times, to keep the whole body in balance.  7.5 BEHAVIORAL ASPECT 
              
              
                |  | Fig 12: Fredrick Matthias Alexander, 
                  (1869-1955), developed the Alexander Method of posture 
                  correction, achieving in the process, deeper insight into the 
                  problem of faulty posture than any one before him. He 
                  discovered the very important principle, USE AFFECTS 
                  FUNCTIONING, known as the Alexander Principle. |  The Alexander Principle states that ……  USE AFFECTS FUNCTIONING Because correcting posture is difficult we have to try to 
            maintain good posture at all times, this is in marked contrast to 
            the concept of taking exercise, where we exercise for say half an 
            hour and then use the body carelessly for the rest of the day. 
            Considerable organic changes have to take place in the muscular 
            system before good posture can be achieved. These changes will take 
            place in the positive direction only if we try to maintain good 
            posture at all times.

                        Movement have informed me that the Alexander Principle 
                        was actually coined by Dr Barlow, even though he himself 
                        calls it the Alexander Principle. To commemorate Dr. Barlow’s memory - he has 
                        contributed a great deal to the understanding of Human 
                        Posture - let us agree to call this principle the 
                        Alexander/Barlow Principle. 
                
 |  |  (The Alexander/Barlow Principle is a very important concept. It 
            is a concept we can use in other ways to enrich our lives )  7.6 SAFETY PRECAUTIONS  
              The musculoskeletal system is enormously complex. If your 
              posture is already good, you are lucky. If you have to correct 
              your posture you are taking on a difficult task. It is best to 
              start by paying attention to your ‘Physical Environment’ 
              Parents should protect the posture of their children by paying 
              attention only to the ‘Physical Environment’. Consciously 
              correcting posture should be delayed till after the age of 20. 
              In the process of correcting posture it is likely that you may 
              feel dizzy at times or you may have a muscle pull (when muscles 
              not used for a long time suddenly come into play). If there is any 
              physical distress do not make any sudden movement and move into 
              PRESENT SPACE. Your subconscious mind will know how to protect 
              you. 
              It is not possible to maintain good posture if you are 
              mentally agitated. Personal worry should be converted into plans 
              of action so that you can focus on the work at hand. 
              You should feel very comfortable in Present Space, if there is 
              any feeling of discomfort it will be because of the following 
              reasons. a) Your mind has blanked out – you are not thinking of 
              any thing, neither are you focused properly on the surroundings. 
              This is a very disorienting state. b) You are not able to suppress 
              your thoughts – if you are worried about something you will find 
              it difficult to move into present space c) you are trying too hard 
              – being in present space is a natural state! 
              When you are tired your posture will become faulty. Lying down 
              for 5 to 10 minutes will rejuvenate you physically and mentally. 
              You can lie down on a mat or rug. If you habitually use a soft bed 
              it is important to find out what a hard surface feels like! 
              Slumping in a chair is a bad way to relax. 
              Posture should not be corrected consciously for more than a 
              few minutes at a time – move into Present Space periodically. Or 
              engage yourself in other activities.
