What is proprioception?
“The perception of joint and body movement as well as the position of the body, or body segments, in space.”
ITS POSITION SENSE RATHER THAN MOVEMENT
What are examples of proprioceptors?
Muscle spindles: Detect change in muscle length
Golgi Tendon Organs: Sense changes in muscle tension
Joint Receptors: Detect movement, position, pressure, and stretch in the joint and send that information to the brain
What is kinesthesia? Examples? What signals does it come from?
Specifically refers to the sensation of movement.
Example: If you close your eyes and someone moves your arm,
- You can determine which direction it’s moving
- How fast it moving
- And when it stops
Comes from sensory signals sent to the brain by the receptors
Is kinesthesia considered proprioception?
Yes, proprioception is a broader term in that is the sense of body position and equilibrium.
Examples of the slide in the lecture are….
- Joint position sense
- Kinesthesia
- Force sense
What is joint position sense? Examples?
Considered a static component of proprioception.
Example: Knowing your wrist is cocked back (extended) in a dark room.
What is kinesthesia in terms of the submodalities of proprioception? Examples?
A dynamic component of proprioception.
Example: Feeling the exact moment your foot begins to slide on a patch of ice, allowing you to make a micro-adjustment before you would actually fall
What does the sense of force mean? Example?
(Sense of Effort)
Example: Lifting a heavy dumbbell compared to lifting a plastic bottle
Identify the sensory receptors that are considered proprioceptors.
What is a joint mechanoreceptors?
Specialized sensory nerve endings in ligaments, capsules, and tendons that detect mechanical changes
What are cutaneous receptors?
Specialized sensory nerve endings located in the skin (dermis and epidermis) that convert physical stimuli such as pressure, touch, vibration, heat, cold, and pain into electrical signals for the nervous system
How is proprioception related to injury and injury prevention?
The Relationship with Injury -
When injured, it damages tissues but disrupts the nervous system.
- Swelling and inflammation interfere with sensory signals
- Damaged mechanoreceptors (in ligaments/muscles) reduce feedback
- Pain alters movement patterns and coordination
In Injury Prevention -
Proprioception reduces the risk of injury by preventing awkward positions, excessive force, or delayed reaction during movement. When proprioception is impaired, joint control decreases and the risk of future injury increases.
Discuss the argument that proprioception cannot be trained
In the study mentioned in class,
Suggest that the improvements seen after “proprioception training” are real, but may not be due to improved proprioception itself, but could be due to motor and neuromuscular changes, not sensory changes
For example, when someone gets better at balancing, it may be because they’re better at controlling movement, not better at sensing position
When people appear to “improve proprioception”, they usually mean,
- Better coordination and motor control
- Improved anticipation and pattern recognition
- Stronger muscles stabilizing joints
And the central nervous adapts
- You can improve how your body uses proprioceptive information differently based on an individual’s issues
