Poor directional control Poor separation of separate limb movements from the overall movement: spatially asymmetric on the left and right but temporally consistent. That is, simultaneous spatial asymmetry: one flexion side extends at a time. Many therapists focus only on spatial asymmetry and do not even notice temporal simultaneity, resulting in making training that is overly passive in maintaining posture but not separating the patient’s limb movements from time. Poor motor combination ability, presence of fixed asymmetric postures (asymmetry) and fixed motor patterns. Upper extremity: Taking the toy in front of him, the child with the non-random motion type first showed abduction of the shoulder joint (horizontal plane motion), then extension of the whole upper extremity (sagittal plane), then adduction of the shoulder joint and then rotation of the forearm forward (coronal plane), and finally extension of the metacarpophalangeal and finger-finger joints to complete the grasping action. The movement of all three planes of motion is almost always present, as if the movement is broken down and then quickly combined. The temporal sequence (sequence) and spatial displacement (range of motion) of each movement are fixed. Lower extremities: both lower extremities rotate around the vertical axis in the horizontal plane, the angle of external rotation of both lower extremities is different, each lower extremity is in hyperextension, the range of flexion is small but the rate is large, resulting in the appearance of doing small fractional movements, if combined with the asymmetry of the upper extremities, and the distal joints of some patients do not move randomly, chorea, looks like a puppet hanging on a string. Postural stability (ability to control the center of gravity), the vast majority of postural stability is accompanied by oscillations, apparently amplified by constant oscillations in the opposite direction on displacement. External stimuli can cause the patient and tension to increase rapidly thus losing postural stability, not only lacking the power of isometric contraction but also losing the power of isotonic contraction in response to external stimuli. The fall resembles scattered blocks. Speech, language, and swallowing: roughly the same, but patients with the involuntary-motor type who have more difficulty pronouncing words will have speech problems, such as asking, “What are you doing there?” Patients with the spastic type will stand down and answer at a slower rate, “I’m going home for dinner.” Even with dysarthria, some vowels or consonants are not pronounced, vocal tone changes are close to normal, and speech problems communicate with people with difficulty or even only parents can understand them, but the grammar is still close to normal. In contrast, a sudorific patient will say one word at a time, “Back, home.” The grammar is faulty, the subject is omitted, intonation changes rarely in the four tones, and sometimes a word is used to represent a word, also only the parents can understand. He will try to omit as much as possible because talking is a very distracting activity for him and can cause him to fall down.
