Bismillahirahmanirahim..
The concept of human posture has
different meanings to different persons:
·
To the orthopedic surgeon, it may be an indication of
the soundness of the musculoskeletal system.
·
To the Kinesiologist, it is a measure of mechanical
efficiency of muscles, balance and of neuromuscular coordination.
·
It is considered as the relative arrangement of parts
of the body. It changes with the positions and movements of the body throughout
life and throughout the day.
·
It is the attitude which is assumed by body parts to
maintain stability and balance with minimum effort and least strain during supportive
and non supportive positions.
Definition of a “ Good Posture”:
·
A good posture is the state of muscular and skeletal
balance which protects the supporting structures of the body against injury and
progressive deformities, irrespective of the attitude in which these structures
are working or resting.
·
Under these conditions, the muscles will function most
efficiently and the optimum positions are afforded for the thoracic and
abdominal organs.
·
There is no single best posture for all individuals.
Each person must take the body he / she has and make the best of it. The “ good
Posture” is the one that suits one’s own condition and the condition of the
environment.
·
e.g. during attention. The normal posture will be
erect, while in extreme fatigue, the normal posture will be that conserves
energy.
·
The “good posture” is the posture in which the body
segments are balanced in the position of least strain and maximum support.
Postural Control:
·
Postural control refers to the ability to maintain the
stability of the body as a whole and body segments “against gravity” or “movement of different body segments” or
“changes in the supporting surface”.
·
Control depends on the integrity of nervous system,
muculoskeletal system and special senses.
Types of Postures
Easy Posture
·
It is a good, symmetrical and balanced position though
this position cannot be maintained for a long time.
·
The subject will therefore shift his weight in a
swaying movement in order to prevent fatigue and to maintain a good circulation
in the postural muscles of the legs when standing.
·
By alternating the main support from one leg to
another, the muscles become periodically unloaded and relaxed.
·
The pelvic inclination is about 60°.
Fatigue Posture
·
It is asymmetrical or sagging posture. This position s
relaxed and can be maintained for a long time as most of the body’s joints are
in semi- flexion.
·
The load on the muscles will decrease and the energy
expenditure is 10 % less than easy posture.
·
The pelvic inclination decreases due to posterior
tilting of the pelvis.
Rigid Posture
·
It is called normal stellung posture or posture of
attention. It doesn’t mean normal posture. This position cannot be assumed for
a long time as most of body’s joints are in extension.
·
Therefore, the load will increase on the joints and
muscles and the energy expenditure is 20% more than in the easy posture.
·
The pelvic inclination increases due to the anterior
tilting of the pelvis.
Faulty Posture
·
Faulty relationship of the various body parts which
produces increased strain on the supporting structures.
·
Inadequate balance over the base of support.
·
Postural deviations will occur with an increase or
decrease of body curvatures and pelvic inclination.
Faulty posture leads to prolonged posture strain which causes
1. Ligaments
stretch which, if becoming permanent, will lead to joint instability increased
faulty posture.
2. Uneven
pressure on joint cartilage which will cause abnormal friction, which in turn
will lead to joint damage ,increased faulty posture.
SO MAKE A CHANGE
The conclusion to understand for Your
Back is A healthy back has three natural curves: a slight forward curve in the
neck (cervical curve), a slight backward curve in the upper back (thoracic
curve), and a slight forward curve in the low back (lumbar curve). Good posture
actually means keeping these three curves in balanced alignment , wallahuaklam.
