Motor Control definition
- Ability to regulate and direct the mechanisms essential to movement
- Study of postures and movements and also the functions of mind and body that govern posture and movement
Posture
static position of any body segment
Movements
Transition from one posture to another
Movement emerges from what?
interaction of individual, task, environment
3 constraints of movement
1) individual
2) task
3) environment:
Individual:Movement and action
Walking, Running, Talking Smile, Reaching
Study the systems that control action
Degrees of freedom
degrees of freedom
how many ways of movement
i.e: flex-ext, abd-add= 2
Individual: Movement and perception
- integration of sensory impressions into meaningful info
- adds interpretation and meaning of afferent information
Individual: Movement and cognition
attention planning problem solving motivation emotions intent
Task: Recovery of function
sensory/ perceptual impairments
motor impairments
cognitive impairments
Task constraints on movement
Recovery of function sequence tasks to achieve movement Functional task groupings discrete vs. continuous tasks stability vs. mobility manipulation components movement variablity
Task: functional task groupings
bed mobility
transfers
ADLs
discrete vs. continuous tasks
discrete: def beginning and end
concrete: variable beginning and end
discrete tasks
kicking a ball
throwing
striking a match
continuous tasks
running
swimming
steering a car
stability vs. mobility
- non moving BOS vs moving BOS
- attention demands increase in mobility activities
manipulation components
adding manipulation increases task demands
- standing, standing lifting light load, standing lifting heavy load
movement variability
open movement: soccer/ tennis
closed movement: confined
factors that constrain movement in individual
movement and action
movement and perception
movement and cognition
Environmental constraints
regulatory
non-regulatory
regulatory constraint
size, shape, weight of cup
type of surface we walk on
non regulatory constraint
background noise
presence of distractions
Why study motor control
Pts retrain clients to move better
Intervention focuses on teaching typical motor patterns
Reflex theory of motor control
- Sir Charles Sherrington- 1906
- Reflexes are building blocks of complex behavior
- reflexes work in sequence to create movement
