Share the main points and precautions of sitting and standing posture for your reference.
sitting position
1. Keep your body straight and relaxed, and don't have too much tilt angle of the thoracic and cervical vertebrae.
2. Keep your shoulders flush and don't shrug.
3. Lean forward slightly naturally. Don't lean back.
4. Hold the pen in one hand, pillow the wrist, lift the wrist or hang the wrist. Look at personal habits and word size. Relax your other hand and put it on the table or press it on paper.
5. The body is about one punch away from the console table.
6. Feet fall naturally. If the seat is high, you can put a pedal on the ground to help your body stay comfortable and relaxed.
7. When sitting and writing, the body should be straight, and the thoracic vertebrae and cervical vertebrae should not be tilted too much. When writing with your right hand, your left hand should relax or hold down the paper and keep it straight. At this time, the body should be relaxed, not tight, not stiff. Be careful not to have obstacles on both sides of your hand, so that you can write fluently.
standing position
1. Stand straight and relax, and naturally lean forward slightly. Don't bend your spine too much, and don't bend down to write.
2. Shoulder level, don't shrug, keep a proper distance from the edge of the table, don't touch or be too far away.
3. Hold the pen in one hand, with the elbow and wrist suspended, so that the pen is vertically downward. Uncontrolled hands naturally rest on the table or press on the paper.
4. Put your feet flat on the ground so that the center of gravity is evenly distributed.
5. When standing, you need to relax, put your feet flat on the ground, and the center of gravity is evenly distributed. When writing, the center of gravity moves between your feet. After a long time, you will find a balance. The more uniform the pressure, the more comfortable you feel.
6. Don't bend the spine excessively, and be careful not to bend down to write, which is very bad for the lumbar spine. So the height of the desk should be appropriate. Writing desks are usually about 10 cm higher than ordinary desks. When you start writing standing up, you can pad your desk a little higher.
