Proprioception/Neuromuscular Control

Afferent Inputs (3 subsystems) • Vision – Horizontal and vertical references

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

Somatosensory System • Afferent Receptors – Free Nerve Endings – Cutaneous Receptors – Articular (Joint) • QA and SA • Pacinian Corpuscle • Ruffini Endings – Capusular collagen – SA – Sensitive to…

Somatosensory System • Afferent Receptors – Free Nerve Endings – Cutaneous Receptors – Articular (Joint) • QA and SA • Pacinian Corpuscle • Ruffini Endings • Golgi-tendon Like Organs – Ligaments – Sensitivity

Somatosensory System • Afferent Receptors – Free Nerve Endings – Cutaneous Receptors – Articular (Joint) – Musculotendinous Receptors • Muscle Spindles • Golgi tendon organs

Location of Muscle Spindle

Somatosensory System • Afferent Receptors – Free Nerve Endings – Cutaneous Receptors – Articular (Joint) – Musculotendinous Receptors • Muscle Spindles • Golgi tendon organs

Path of GTO to Spinal Cord

Spinal Cord Entry • Dorsal Roots • Synapse with interneurons

Spinal Cord Entry • Dorsal Roots • Synapse with interneurons • Monosynaptic Stretch Reflex

Spinal Cord Entry • Dorsal Roots • Synapse with interneurons • Monosynaptic Stretch Reflex • Polysynaptic Reflex

Pathways to the Brain • Anterolateral Pathway • Dorsal Column

• Brain Stem • Cerebral Cortex The Brain • 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
