1, the bed must be as flat as possible. 2.The head position should be fixed on the pillow, not flexible and movable. 3.The shoulder joint (mainly the scapula) and pelvis under the hemiplegic side should be padded with thin pillows and fixed on the pillow to prevent the scapula from retracting, the pelvis from sinking and rotating and the hip joint from rotating in the future. 4. Upper limb on the hemiplegic side: shoulder joint slightly abducted, elbow extended, wrist extended, fingers extended, palm down, and fixed on the pillow. Note that the palm of the hand should not be suspended. 5.Lower limb on the hemiplegic side: flex the hip, flex the knee, and step on the bed (pay attention to give some support or protection) or extend the hip, extend the knee, and dorsiflex the ankle by 90° (support can be put on the bottom of the foot or place a thong shoe or support such as a foot rest), and it should be noted that a thin pillow is placed under the knee of the hemiplegic side (i.e. at the N fossa) to avoid knee hyperextension. 6. The limb on the healthy side can be placed in a comfortable position. 7, Note that semi-recumbent position should be avoided, because the trunk flexion and lower limb extension posture of this position directly reinforces the spasticity pattern.
