The left lower extremity in front or the right lower extremity in front relates to the direction of twisting of the human body, and reversing the twisting of the human body is the key to treating chronic diseases. The human body is apparently symmetrical but essentially torsional. Balance and symmetry are relative and torsional imbalance is absolute. Why is this so? How does this relate to human health and disease? As the left and right hemispheres of the human brain are differentiated differently, the left brain is more developed and the left and right brain functions are differentiated. The right leg is usually more flexible, and usually like to put the right leg in front, when standing the center of gravity naturally in the back of the left leg, this habit has existed for a long time since childhood, the existence of the angle between the two legs is bound to produce torsional effect, the long-term existence of the habit can make the pelvis in three-dimensional space to produce torsional deformation. 1, in the sagittal plane around the X (left and right axis) axis to produce clockwise rotation, resulting in the entire spine in the horizontal plane around the Y axis to produce clockwise twisting. 2.The pelvis produces counterclockwise rotation in the coronal plane around the Z (anterior-posterior axis) axis, causing the sacral vertebrae to be forced to swing laterally (right high and left low), resulting in the whole spine to be laterally curved in the coronal plane (generally the lumbar vertebrae are convex to the left and the thoracic vertebrae are convex to the right). 3. Counterclockwise rotation of the pelvis in the horizontal plane around the Y (upper and lower) axis causes the sacral vertebrae to tilt back and forth and the curvature of the entire spine to change. The above-mentioned changes disrupt the small joints of the spine and cause small deviations in the trajectory of joint activities. The presence of long-term torsion produces many undesirable consequences, such as: joint wear and tear hyperplasia, synovitis, intervertebral ligament strain, disc herniation and other pathological changes. Causes cervical, thoracic and lumbar spine and related diseases. Changing the habits of both legs is the only way to reverse the body. Getting into the habit of having the left leg in front of the body in any position will cure spinal and related disorders by creating a reverse directional twist of the pelvis and spine. There are no drugs that can actually cure chronic diseases, and habit modification is the key to prevent recurrence of the disease and is so significant that no other method can replace it and should be taken seriously enough, otherwise the chronic disease will remain untreated for a long time. All other exercise methods that do not take into account the pelvic torsion are not justified (such as: “rice” exercises, etc.), are not credible. In short: the left front and right back can ensure the health of the entire spine, is a set of prevention, treatment, health care and health care in one important habit, it is recommended that 98% of people adopt this good habit of guarding health. Method: require the habit of standing, sitting, sleeping, labor and sports to adhere to the left leg in front of the left leg kicking movement and right leg single leg jumping movement is conducive to the reverse movement of the pelvis and spine and treat the disease, simply these two movements can treat spinal diseases, such as cervical spondylosis, you left leg to do the shuttlecock action 30 times, immediately will get good results, 98% of the people effective. Note: You cannot use your right leg to kick the shuttlecock, and be careful with safety. Patients who have already seen me should take it seriously! This is the key to prevent recurrence.
