Proprioceptive Neuromuscular Facilitation Techniques in Rehabilitation pt 1

A set of vocabulary flashcards covering key concepts related to Proprioceptive Neuromuscular Facilitation techniques in rehabilitation.

Proprioceptive Neuromuscular Facilitation (PNF)

A therapeutic exercise approach based on functional human anatomy and neurophysiology, using sensory input to enhance motor output.

Objectives of PNF

To explain the neurophysiologic basis of PNF techniques, discuss their rationale, identify basic principles, demonstrate various techniques, and describe patterns for different body regions.

Basic Principles of PNF

Includes teaching PNF patterns, using visual and verbal cues, employing manual contact, and ensuring proper body mechanics.

Muscle Spindles

Sensory receptors within muscles that detect changes in muscle length.

Golgi Tendon Organs

Receptors that sense changes in muscle tension.

Autogenic Inhibition

Relaxation of a muscle in response to its own stretch, mediated by afferent fibers.

Reciprocal Inhibition

The process where the contraction of one muscle group (agonist) leads to relaxation of its opposing muscle group (antagonist).

Stretch Reflex

A reflexive response that occurs when a muscle is stretched, involving muscle spindles and resulting in muscle contraction.

Contract-Relax Technique

A stretching technique that involves passively moving a body part into an agonist pattern and then involves the patient contracting against resistance.

Rhythmic Stabilization

An isometric contraction technique that promotes co-contraction and stability of opposing muscle groups.

D1 and D2 Patterns

Specific movement patterns used in PNF that involve flexion and extension of upper and lower extremities.

Range of Motion (ROM)

The full movement potential of a joint, typically measured in degrees of a circle.

Viscoelastic Changes

Changes in muscle properties that affect its ability to stretch, influenced by the rate of stretching and duration of holding the stretch.

Goals of Muscle Energy Techniques

To achieve muscle lengthening, strengthen weak muscles, reduce localized edema, mobilize joints, and stretch fascia.
