Document Summary
Mechanics constraints such as body mass distribution and force generation. The degree of freedom problem resulted from the multi-segmented structure of human body. All of the above are constraints on postural control development. Sensory-percetpion constraints (sensorimotor mapping: somatosensory (moving room experiment and children cannot integrate multisensory information, vestibular system, visual information. Mechanical constraints: multisegmented body, top-heavy, small base of support, ability to create torque. Infants cant generate torque and cannot anticipate to create torque. Neuromuscular constraints: degree of freedom (multi-segmented body) Prior experience: 4 groups of infants active exercise, passive exercise, no exercise and control, active exercise early onset of walking. Active of moving from one place to another: can self-organize into locomotion. Dependent on the exact task to be done. Dependent on the interaction of the body systems that will perform the task. Infants who start to stand e(cid:454)te(cid:374)d all joi(cid:374)ts, a(cid:374)d do(cid:374)"t sepa(cid:396)ate them. Joints capable of moving separately- but need to flex one and extend others.
