UNIT 2: Week 3 Content

-afferent (sensory) -efferent (motor)

-input can be altered -mechanoreceptors in skin, ligaments, muscles, tendons

-output can be altered -muscle inhibition

-agility -activation -balance -coordination -proprioception

-the ability to voluntarily contract a skeletal muscle in isolation

-arthrogenic muscle inhibition

-following injury clients may be unable to voluntarily contract an otherwise healthy muscle

-ask client to contract the muscle -observe for isolated muscle contraction and signs of associated function -palpate muscle to determine degree and duration of voluntary contraction before fatigue

-the ability to change direction to achieve a specific goal

-modified agility T test

-refers to the complex motor control process that integrates relevant sensory information to execute appropriate motor actions to control body positions

-when the center of gravity is within the base of support

-visual -proprioceptive -vestibular

-BESS

-Y balance test

-the ability to execute accurate, smooth, controlled movement patterns

-observation of the quality of a single leg squat (knee vs hip dominant, dynamic knee valgus etc)

-the ability to sense limb movement and positioning in space

-may be measured through joint position sense (ability to reproduce a joint position)

-resolve neuromotor impairments -reduce injury recurrence risk

-frequent practice -meaningful practice -vary sensory input -attentional focus -implicit learning -autonomy

-most effective way to build a skill is repetition

-important and challenging for the client -simulate the clients function/goal

-challenge sensory systems
