Computer games in charge of the affairs of the back pain has increased among adolescents in the nation? The problem of low back and neck pain among adolescents is likely to increase significantly in coming years, This seems on the cards considering the health problems associated with obesity, reduced activity levels, and the popularity of passive entertainment systems such as game stations that encourage further inactivity and prolonged sitting in the age group of adolescents. Terry O’Brien of back problems in the United Kingdom said: “While 80 percent of the population are likely to experience lower back pain at some point in their lives, there is a disturbing trend in amount of back pain in adolescents. It is well established that the presence of another family member with a history of back pain means you’re more likely to develop back pain as a teenager. As the family functioning and stress of living has increased. High levels of stress, anxiety and depression are also associated with back pain in adolescents. Back pain is often caused by sports activity and static postures such as sitting. It is also known that specific sporting groups such as rowers are at higher risk of back pain. Children seem to fall into two major groups, those who do little activity and those who do too. Both groups are prone to back pain. However, it is the disturbing trend of inactivity among youth is the greatest source of concern. Fueled by the dramatic rise of computer games and multimedia consoles. “ Let now the bio-mechanics. Bio-mechanics and its association with back pain. When our body is upright, he is in a state of unstable equilibrium because the base is low and the center of gravity is a long way over. Therefore it must be balanced by keeping the center of gravity on the base, otherwise the body would fall over. Balance: The firmness of the body depends on the size of its base and the distance from the center of gravity of the base. An object with a wide base and low center of gravity is not easy to disturb. The first thing needed to achieve a good posture is to straighten the neck, keep your chin down and back. The second important thing is proper deep breathing. The line of gravity falls fundamental standing in front of the ears and in front of the cervical and thoracic through the lumbar vertebrae, through the hip and slightly forward of the ankle. But this probably varies among individuals according to their construction and height. ”Biomechanics is the branch of science concerned with the understanding of the interdependence of structure and function of living things with respect to the kinematics and kinetics of movement” Wrong position associated with the following: Genetic diseases, family association, irregular / no exercise, bad habits when sitting or standing, carrying excessive weight, (school / shopping) Underweight / Overweight (poor nutrition) Mental attitude towards oneself. Biomechanics is our way of describing how each bit of your body moves relative to the other bit. Our bodies are amazing to compensate when things are not quite perfect, but unfortunately, when we run out of offsets we usually end up with the pain and stiffness. Let’s take a look at some of the most common biomechanical problems: Problem 1. Because it’s cool not to link trainers and shoes so far, but prevents the shoe to support the inside of the foot and allows the foot to roll or “pronation” too much standing and walking. This means that the knee and hip rolls inwards too much which makes the calf to the inside and the inner thigh short. The iliotibial band can then rub the outside of the knee hurt. Higher up, the muscles become too long down and stop working as they should, which puts additional stress on the pelvis and lower back joints. Before you know you have back pain, knee pain and ankle! And all this because fashion! Problem 2. Whether you are 5 miles or 500 miles per day of your car seat is really important. In many cars the rear seat base slopes. In fact, some of the most expensive cars are the worst because they want you to feel “comfortable” and safe in the seat. However, this position forces your pelvis to sit too far back. Once that happens in your lower back and upper back flex too forward, but the neck muscles have to work hard to stop bending the head too much and you can see where you go. This position requires the shoulder blades and then to stretch too far forward and a significant stress is placed on the front and back of the shoulder. The result is a pain in the neck and / or upper or lower back pain. This position can aggravate sciatica because it is a big stretch for the nerves. The solution is to increase the return of the chair so that it becomes more horizontal. Some cars allow you to change that but if yours can not sit on a small pillow or cushion to buy a special wedge shape that fits into the seat. Terry O’Brien United Kingdom, back problems.
