DEFINTIONS
Neuromuscular Control Is the integration of a number of sensations from
the periphery. These “inputs” from the periphery are combined with a coordinated muscular response as the outcome (the efferent response)
![Page 4: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/4.jpg)
DEFINITIONS
Kinesthesia
It is the sensation or feeling of joint motion or acceleration. It is also the awareness one has of their body in space (knowing how quickly your hip, knee and ankle joints are moving when you walk)
essentially, what you feel when a joint is moving These sensations are transmitted to the CNS via
afferent pathways.
![Page 5: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/5.jpg)
DEFINITIONS
Proprioception?
Is both the conscious and unconscious appreciation of joint position…or the ability to determine the position of a joint in space (i.e. where your foot is when you walk, in relation to your hip, knee and ankle)
These sensations are transmitted to the CNS via afferent pathways.

DEFINITIONS
Muscle stiffness?
It is the muscle’s ability to resist stretch/deformation. It is through this resistance that there is an increase in joint stability/restraint to joint displacement.

PHYSIOLOGY
Mechanoreceptors?
They are specialized nerve endings that respond to mechanical changes (deformation) of tissue. the change in the tissue causes the mechanoreceptor to “fire”.
![Page 8: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/8.jpg)
PHYSIOLOGY
MECHANORECEPTORS:There are 2 types:
1. ArticularFound within joints (ligament, capsule, menisci,
and labrum)Function: stabilize and guide skeletal segments
while providing mechanical restraints to abnormal joint movements.
![Page 9: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/9.jpg)
PHYSIOLOGY
MECHANORECEPTORS: 2. Tenomuscular:
Include both muscle spindles, embedded within the skeletal muscle, detect length and rate of length changes (the stretch reflex) and
![Page 10: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/10.jpg)
GTO’s responsible for monitoring muscle tension or load, located within the tendon and tenomuscular junction, force detectors (inhibit muscle activation when excessive loading might cause damage under load)
![Page 11: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/11.jpg)
MECHANORECEPTORS
Both respond to changes in muscle length. GTO’s also respond to changes in muscle tension.
Muscle spindles elicit a reflex contraction in the agonist muscle
GTO’s cause relaxation (protection)

Muscles
Agonist –the muscle that contracts to produce a movement
Antagonist – the muscle being stretched in response to contraction of the agontist
![Page 13: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/13.jpg)
PHYSIOLOGY
neural pathways of peripheral afferents Either one (or both) of the mechanoreceptors
respond to a signal (i.e., deformation in joint; change in muscle length/tension).
Send signal along afferent nerve to the CNS (cerebral cortex, or directly synapses at spinal level…ie knee jerk of muscle spindles)
CNS evaluates the signal, then responds via efferent nerve to the appropriate muscle/tendon for the required response.

REESTABLISHING NM CONTROL
Why is NM control important in the rehab process?
When injured, there is an increase in the response time of the mechanoreceptors.
This leads to mechanical instability and functional instability (i.e. balance on foot)
![Page 15: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/15.jpg)
REESTABLISHING NM CONTROL
Therefore we must retrain the Mechanoreceptors in order to increase the reaction time and decrease the chance of potential re injury due to mechanical instability.
![Page 16: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/16.jpg)
REESTABLISHING NM CONTROL
Objectives of NM Rehabilitation Four key elements
1) Proprioceptive amd Kineshetic sensation
2) Dynamic joint stability
3) Reactive NM control
4) Functional motor patterns

REESTABLISHING NM CONTROL
What are some techniques that can be used to “train” or improve an athlete’s neuromuscular control?
![Page 18: RE-ESTABLISHING NEUROMUSCLULAR CONTROL. DEFINITIONS DEFINITIONS: What is neuromuscular control? What is kinesthesia? What is proprioception? What is muscle.](https://reader035.fdocuments.us/reader035/viewer/2022081515/551b3dbb550346dd1a8b54fc/html5/thumbnails/18.jpg)
REESTABLISHING NM CONTROL
Training NM Control CKC activities Balance training Reflex facilitation through reactive training Stretch shortening exercises (plyos) Biofeedback training

REESTABLISHING NM CONTROL
LOWER EXTREMITY TECHNIQUESCKCBalance training (PWB stable – PWB
unstable) ( wobble boards etc) Combine strength and balanceStretch shortening exercises (plyos)Reactive NM activities (trampoline hopping)Functional activities

REESTABLISHING NM CONTROL
Important point:During rehab, it is important to progress the
athlete into “unstable” positions. By doing so, the athlete will “learn” what the position feels like, and how to prevent the position from happening/over-extending.
i.e. in shoulder dislocation, train in increasing abduction/external rotation
