Study Notes
Motor Learning and Postural Control
- Sensitisation increases neural system responsiveness and can occur through sensory learning and associative learning, involving classical and operant conditioning.
- Procedural learning leads to automaticity and habits, while declarative learning results in consciously recallable knowledge.
- Various theories of motor learning include closed loop processing, open loop processing, and ecological theory, with possible stages of cognitive, associative, and autonomous learning.
- Motor learning progresses through novice, advanced, and expert stages, involving control of degrees of freedom and increasing automaticity.
- Practical applications of motor learning include transfer of learning to new tasks/environments, mental practice, feedback, and practice conditions.
- Recovery of function post-injury involves considering recovery versus compensation, stages of recovery, and factors affecting recovery such as age, lesion characteristics, experience, pharmacology, and training quality.
- Postural control involves stability and orientation, with balance as the ability to maintain equilibrium at rest or in motion.
- Postural sway is described as mediolateral or anterior-posterior, and balance involves maintaining the body within the limits of stability.
- Systems required for postural control include environmental perception through proprioception, vision, and vestibular cochlear systems.
- Afferent neurons send signals to the CNS, which makes decisions and sends information to the motor systems via efferent pathways to make necessary postural adjustments.
- The cerebellum anticipates and coordinates postural adjustments and is important in learning new tasks, reducing the difference between anticipation and actual outcomes as learning progresses.
Developmental Milestones in Infants' Postural Control
- Infants aged 4-6 months should achieve prone weight bearing on forearms with some strength against gravity and chin tuck, and they should be able to track objects with their eyes and bring hands and feet to the midline.
- Key goals for infants aged 4-6 months include eye-hand coordination and reaching and grasping toys, while those aged 9-15 months should develop fine pincer grasp and constructive play.
- Infants aged 6-8 months should progress to reaching forward from the base of support and sitting upright, and those aged 7-9 months may demonstrate commando crawling.
- Infants aged 9-15 months should be able to crawl on hands and knees, stand alone with a wide base of support and lumbar lordosis, and squat to play with eccentric control of quadriceps and calf range.
- Postural control development in infants is influenced by intact musculoskeletal system, proprioceptive, visual, and vestibular systems, and maturation and experience.
- There is a large variation in postural control development between females and males, and the process of mapping individual senses to actions, such as vision stimulating action in neck muscles for head righting, is crucial for postural control.
- Infants develop postural responses that are reactive (responding to perturbations) and anticipatory (preparing the body for movement or in anticipation of being perturbed).
- Adaptive postural responses are the last to develop in any particular orientation or posture, and protective responses, such as extension of limbs and movement away from the trunk, act as the second line of defense to protect the head from hitting the surface.
- Postural adjustment or protective response recruitment in infants is influenced by the speed and strength of the perturbing force, and they develop stepping strategies in lower limbs when achieving standing.
