Afferent Inputs (3 subsystems)
• Vision• Vestibular
– Head movement
– Inner ear
– Balance and posture
• Somatosensory– Peripheral Afferent
Receptors
Somatosensory System
• Afferent Receptors– Free Nerve Endings
– Cutaneous Receptors• Few respond
• Respond at extreme ROM

• Afferent Receptors– Free Nerve Endings
– Cutaneous Receptors
– Articular (Joint)• QA and SA
• Pacinian Corpuscle– Joint capsule
– RA
– sensitivity

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
