The whole-body hyperextension pattern and the whole-body hyperflexion pattern, i.e., the whole-body abnormal posture, may be harmful to movement even if the child has a high level of motor development. Generalized hyperextension pattern is a generalized hyperextension pattern caused by hypertonia of the extensor muscles, mainly head dorsiflexion (neck hyperextension), which affects the child’s development such as turning and sitting balance. Most commonly seen in children younger than 1 year old or seriously ill children. (1) Treatment principles: The main focus should be to reduce the muscle tone of the extensor muscles, while increasing the strength of the flexor muscles. (2) Passive exercise: the child is in sitting or prone position, the trunk is fixed, the therapist controls the child’s head and trunk with his hands, and repeatedly pulls the cervical and lumbar muscles in the sagittal plane to reduce the muscle tone of the child’s cervical and trunk muscles. The child is placed in a prone position and the therapist gently compresses the muscles of the child’s neck and shoulders to relax the muscles, and the child’s cervical muscles are stretched under the effect of head gravity. (3) Active movement: For younger children, brightly colored toys with sound can be used to move up and down, so that the child can actively move the cervical muscles in the process of chasing the eyes and induce coordinated contraction and diastole of the left and right sides of the trunk. For the older children, the child can be told to lower or raise the head repeatedly to control the contraction of neck muscles and the left and right rotation of the trunk, so as to inhibit neck hyperextension through the active rotation of the neck and the active movement of the neck flexors. (4) Key point control: The therapist selects the shoulder joint as the key point, the child is seated, and the therapist passively pulls the upper arm of the child to make the shoulder joint retracted to inhibit neck hyperextension. Flex the hip and knee joints of the child to make the child sit in a cross-legged position, and the therapist will pull the upper limbs of the child forward to make the trunk in a flexed position, and the neck hyperextension can be inhibited in a whole body flexed state. The therapist can also sit the child on his or her chest and use his or her trunk to inhibit the child’s cervical hyperextension, control the child’s head with both hands, fix the child’s trunk with both forearms and limit the upper extremity abduction movement. The whole body flexion pattern caused by the high tone of the whole body flexor muscles includes flexion and inversion of the proximal joints such as the shoulder and hip joints, and the distal joints such as palmar flexion of the wrist and ankle flexion. The child mostly adopts a lateral recumbent posture because the head, trunk and limbs are unable to resist gravity, resulting in an arched-back sitting position, forward sitting position, and difficulty in achieving elbow support, hand support, and four-point support, thus affecting the development of motor functions such as crawling. (1) Treatment principles: The main focus should be to reduce flexor muscle tone while increasing extensor muscle strength. (2) Passive exercise: place the child in a prone position on the bobath ball, hold the child’s legs, push them back and forth, sway them from side to side, and in the process the child’s trunk is stretched. The child is seated on the bobath and the therapist pulls the child’s upper limbs upward behind the child and causes the upper limbs to abduct and externally rotate. With the child in supine position, the therapist controls the child’s trunk with both hands and exerts moderate force, and the flexion of the child’s extremities is stretched to extension by gravity. (3) Active movement: The child rides on the round roll, makes squatting movement, and can grasp the toys on the top after standing up, thus stretching the trunk and limbs. (4) Key point control: The therapist pulls and holds the child’s hand and moves the shoulder joint to the abducted and externally rotated position, which can promote trunk extension and head straightening. In this key point control process, the therapist can make the child take different positions such as kneeling, sitting and standing according to the different motor development stages of the child.
