Proprioception/Neuromuscular Control
Afferent Inputs (3 subsystems)
• Vision– Horizontal and vertical

Afferent Inputs (3 subsystems)
• Vision• Vestibular
– Head movement
– Inner ear
– Balance and posture
• Somatosensory– Peripheral Afferent
Receptors
Somatosensory System
• Afferent Receptors– Free Nerve Endings
• Hair follicles
• Pain receptors
Somatosensory System
• Afferent Receptors– Free Nerve Endings
– Cutaneous Receptors• Few respond
• Respond at extreme ROM
Somatosensory System
• Afferent Receptors– Free Nerve Endings
– Cutaneous Receptors
– Articular (Joint)• QA and SA
• Pacinian Corpuscle– Joint capsule
– RA
– sensitivity

Path of GTO to Spinal Cord
Spinal Cord Entry
• Dorsal Roots• Synapse with
interneurons
Spinal Cord Entry

interneurons• Monosynaptic Stretch
Reflex• Polysynaptic Reflex
Pathways to the Brain
• Anterolateral Pathway• Dorsal Column
The Brain
• Brain Stem
• Cerebral Cortex
• Cerebellum
Motor Control Maintenance: How do we control motor
Performance?• FEEDFORWARD AND FEEDBACK
• Feedforward– Preactivation– Functions
Motor Control Maintenance: How do we control motor
Performance?• FEEDFORWARD AND FEEDBACK
• Feedback
• So what?
• The Key
Components of Neuromuscular Control Training
• Proprioception
• Kinesthesia
• Dynamic Stability
• Preparatory Muscle Contractions
• Reactive Muscle Characteristics
• Conscious and Unconscious Movement Patterns
Re-establishing Neuromuscular Control
• Four Basic Elements– Proprioceptiom– Dynamic Joint Stabilization– Reactive Neuromuscular Control– Functional Motor Patterns
Phases of Neuromuscular Control Training
• Phase I
• Phase II
• Phase III
• Phase IV
