1. Forward head--This causes contant strain on the muscles of the upper back, neck, and head. The cervical spine is in constant flexion which can cause damage to the vertebrae, pinch nerves and decrease blood flow to the head. This in turn can cause migrane headaches, tension and chronic fatigue.
2. Dropped chest--This causes the head to fall forward out of alignment and puts a constant strain on all the muscles in the back. In this posture, decreased lung volume and shortness of breath is often a problem. Fibromyalgia and chronic fatigue exist in this posture.
3. Shoulders rounded forward-- This decreases the space in the shoulder joint which can inhibit the major muscles in the arm to properly perform. This can cause strain and injury to the rotator cuff and develop overactive upper traps and neck muscles. Major causes of this condition could be Fibromyalgia, chronic fatigue and headaches.
4. Pelvic instability-- This can come in three forms. 1. forward tilt which puts strain on the lumbar and pushes upper body forward out of good alighment. Symptoms can include back pain and sciatica. 2. Backward tilt which is a flat lower back and causes strain on the lumbar. Shoulder tend to be rounded and chest dropped. Causes of this posture could back and hip pain and sciatica. 3. Rotation is when one side of the pelvic rotates forward and puts stress on the muscles of the opposite side of the low back. Risks of this posture can include instability of the knees, ankles and feet.
5. Knees Locked--This puts stress on the knee joint and creates instability and loss of balance. It also pushes the upper body forward out of alignment and shifts weight from entire foot to heel causing strain on the arch.
6. Feet pointing in or out--This type of standing causes strain on the hops, knee, ankles, and feet. It slao changes the the walking stride causing inefficiency and could lead to injury.
