Week 5 (Impairment of Co-ordination) Flashcards
Loss of co-ordination of voluntary muscles to meet environmental demands is due to
- Timing (onset, speed, duration)
- Amount of force
- Mode of contraction
Assessment of co-ordination
Speed/accuracy
- Assess: smooth/jerky of tasks
- Measure: # in 15 seconds - a score and compare to the normal cycles per 15 seconds
Clinical implication of postural adjustments
Need to train task and not balance as a seperate entity e.g. train sitting, standing, walking, running, etc.
Clinical implications of task and context specific
Need to consider nature of external support (rails vs harness) - different muscles activate during different activities
What are the 4 inputs of sensory information
Vision, proprioception, tactile, vestibular
Proprioceptive input provides
Sensory information about body and limb position and movement that is transmitted to the CNS from the proprioceptors
Tactile sensation provides
Information about BOS’s contact with environment e.g. foot on floor tells us how stable the ground is, respond to pain, temperature touch and pressure
Vestibular input provides
Information about bodies orientation and movement
Vision input provides
Information of motion of body relative to the environment, vertical alignment and when the body will make contact with objects in the environment
Balance training programs must…
- Provide high challenge to body - controlled movements of body, feet close together, minimal arm support
- High dose (>50 hours)
- Ongoing exercise is necessary
Measurement of balance
Timed Up n Go Test
- Patient has to get up from a chair and walk 3m and sit down and if they are <10 seconds then good. >14 is a good indicator of falls.
Outputs of balance
Strength, ROM, co-ordination
