Physiology W1 Online work
Definitions
Motor control
Ability to maintain and change posture and movement
Complex neurological and mechanical processes
Explains/insight into
How CNS coordinates movement
How sensations are used to select and control movement
Perceptions of ourselves, a task we perform and enviro influence movement behaviour
Movement organisation
Affected by...
The task
Individual
Environment
Regulatory factors
enviro aspects that affect movement
Snow walking for e.g.
Non-regulatory factors
Affects the performance of the individuals movement
Movement itself doesn't have to change
Timeline
Motor control = fractions of a second
Learning = hours, days or weeks
Development = months, years and decades
Motor control, Motor learning and Motor development
Self movement control
Control of movements in changing enviro
Can results from neurological system developing
gross to fine motor mvts
Motor problems
Overcome gravity
Move large head vs small body
Head control needed!!!
Stability vs mobility of Head, trunk and limbs
Control task specific movements
Depends on cognitive and perceptual ability also
Motor control development
Relationship b/w mobility and stability
Automatic postural control developing
Role of sensation
Cues reflexive response to occur
Accuracy of mvt. info
4 stages of motor control
Mobility
Random mvts in first 3 months
Lacks purpose + reflex based
Stability
Due to postural maintenance
Maintain stability in WB antigravity postures
tonic holds + co-contraction
Controlled mobility
Mvts. within posture due to Weight shifting in a posture.
Mobility superimposed on developed postural stability
Distal mobility with proximal stability
Skill
Mvt. from one posture to another
Most mature mvt type
