Q

Mechanoreceptors

A
  1. Input received by the skin, muscles, and tendon that facilitate a motor response.

Q

CNS

A
  1. Spinal cord
  2. Brain stem
  3. Cerebral cortex
17
Q

Spinal cord

A
  1. Reflexes
  2. Joint quick motion protects body with a quick reflexive contraction
  3. Provide joint stability
18
Q

Brain Stem

A
  1. Receives input from proprioceptors, eyes, and ears
  2. Assist in maintaining balance
  3. Maintains posture and position
  4. Vestibular
  5. Swtitch board for incoming and outgoing messages
19
Q

Cerebral cortex

A
  1. Conscious movement
  2. Controlled movement
  3. controlled movement is learned before it becomes automatic
20
Q

How does the neuro system talk to muscular system?

A
  1. Afferent nervous system: skin, joint receptors, etc.
  2. CNS
  3. Motor response
21
Q

Balance Sensory Input

A

Systems involved:
1. Vestibular system (20%)
2. Oculomotor system (10%)
3. Proprioceptor system (70%)

22
Q

Vestibular

A
  1. Inner ear
    -sick
    • concussion
  2. Allows the eyes to remain steady when body is on motion
23
Q

Oculomotor system

A
  1. Provides basic feedback of where you are
  2. Are you moving or is the environment
  3. Visual fixation can help balance,.
24
Q

Proprioceptive system

A
  1. Somatosensory feedback
  2. Foam surface
    3.Uneven surfaces
25
Q

How does proprioception affect performance

A

Interaction with group
2. Info
3. Command
4. Better performance
5.Less injury

26
Q

Balance Exercises (Romberg’s test)

A
  1. Mainly tests position sense
27
Q

Stork Stance

A
  1. Single leg balance
  2. Making dynamic stability harder
    a. Somatosensory feedback
    b. Removal of ocular feedback
28
Q

Dynamic Balance Test

A
  1. SEBE (star excursion balance exercise test)
  2. Y balance test/arm balance exercise test
29
Q

Coordination

A
  1. Complex process by which a smooth pattern of activity is produced by a combination of muscles acting together with appropriate intensity and timing
  2. Muscles
    a. Stimulate to provide an activity
    b. Some inhibit activity
  3. Muscle strength
30
Q

Shoulder Kinematics

A
  1. Correct strength to be able to get shoulder into appropriate position to throw or hit
31
Q

Ankle mobility

A
  1. Must have to perform squat, correctly run, jump, etc.
  2. Don’t forget to check when doing assessment
32
Q

Activity Perception

A
  1. Awareness of what the activity involves
    a. what posture do i need etc.
    b. Does the activity feel right
33
Q

Feedback

A
  1. Action occurs
  2. Proprioceptive system makes adjustments to correct system
  3. Ex. throwing a ball, catching a ball as a baby
34
Q

Feedforward

A
  1. Response to environment
  2. Action based on previous knowledge and activity
  3. Based not on error correction but pevious expericence
    a. walking down steps
  4. more automatic
35
Q

Repetition

A
  1. Will eventually become automatic
  2. Development of accuracy and coordination
36
Q

Progression of Proprioceptive Activities

A
  1. Balance –> coordination –> agility
  2. Simple to complex tasks
  3. Slow, deliberate to fast, inherent
  4. Narrow to broad focus
  5. Internal to external focus
  6. Closed to open environment
  7. Advancement is made only after the activity is mastered.
37
Q

When should proprioception exercises be performed?

A
  1. Early in rehab session
  2. Repetition is key
    a. Performance must improve each time
