Stability Flashcards
What is the correct definition for static balance?
The ability to maintain a base of support with minimal movement
What is the correct definition for dynamic balance?
The ability to maintain a stable position whilst performing a task
Which receptor type helps with proprioception?
Mechanoreceptors
Kinanesthesia refers to the awareness of the position and movement of the parts of the body by means of sensory organs, true or false?
True
An afferent response is a message that sends a signal to the brain based on proprioceptive input, true or false?
True
An efferent response is an appropriate response from the brain based on an afferent input, true or false?
True
What does the following definition refer to?
An ability to sustain body equilibrium by maintaining the centre of mass with the base of support limits.
Postural Stability
Which passive tissue that help with joint stability?
Ligaments
Are deficits in stability due to a MCL sprain an example of mechanical instability?
Yes
Which tests assesses dynamic balance?
Modified BASS test
Star excursion
Definition of proprioception.
Ability to integrate sensory signals from the mechanoreceptors to determine
body segment positions and movements in space
What is neuromuscular control?
The interaction of the nervous and muscular system to
create coordinated movement to maintain and restore
functional movement.
- Appropriate efferent response to afferent proprioceptive input
- Proprioceptive input is vital for neuromuscular control
Feedback?
Feedback is a corrective
response following afferent
signals based upon a
movement-to-movement
basis.
Feedforward?
Feedforward control is
anticipatory actions that occur
before a change in stimulus
Describe the joint reaction process?
Peripheral receptors: Skin, joint, tendon, muscle spindles, visual, vestibular
¬
Afferent signal
¬
CNS: Interpretation, response generation
¬
Efferent signal
OR
Feedforward to muscle spindle
¬
Motor output (muscle)
¬
Feedback to the start
