    Study Notes

    Definition of PNF

    • Proprioceptive refers to sensory receptors providing information about body movement and position.
    • Neuromuscular involves the interaction between nerves and muscles.
    • Facilitation means making an action easier.
    • PNF combines diagonal movement patterns with neuromuscular techniques to enhance motor responses and neuromuscular control.

    Key Features of PNF

    • Utilizes diagonal movement patterns to improve functionality during activities.
    • Stronger muscle groups activate to support weaker muscle groups in diagonal patterns.
    • Sensory cues, including proprioceptive, cutaneous, and auditory stimuli, enhance motor responses and facilitate movement.

    Applications of PNF

    • Effective in neurorehabilitation and treatment of musculoskeletal conditions.
    • Versatile throughout all rehabilitation phases, from early isometric techniques to high-speed diagonal movements against resistance.

    Basic Principles of PNF

    • Diagonal patterns guide movement.
    • Manual contact ensures proper positioning of the therapist's hands.
    • Resistance is maximized while allowing smooth and pain-free movement.
    • Stretch stimulates muscles used in the desired movement pattern.
    • Verbal commands assist in guiding the patient through exercises.
    • Traction and approximation may be employed to influence muscle activation.
    • Normal timing supports a sequence of muscle contractions from distal to proximal regions.
    • Correct body positioning enhances effectiveness and safety.

    Diagonal Patterns

    • Involves multiplanar, diagonal, and rotational movements for limbs, trunk, and neck.
    • Patterns are identified as Diagonal 1 (D1) and Diagonal 2 (D2) for both upper and lower extremities.

    Components of PNF Patterns

    • Each pattern includes flexion/extension, abduction/adduction, and rotation components, with movement occurring diagonally.
    • Patterns are named according to movements around proximal pivot points (hips or shoulders).

    Upper Extremity PNF Patterns

    • D1 Flexion: Shoulder flexion, abduction, external rotation, wrist radial flexion, and finger extension.
    • D1 Extension: Shoulder extension, abduction, internal rotation, forearm pronation, and wrist ulnar extension.
    • D2 Flexion: Shoulder flexion, adduction, external rotation, forearm supination, wrist radial flexion, and finger extension.
    • D2 Extension: Shoulder extension, abduction, internal rotation, forearm pronation, and wrist ulnar extension.

    Lower Extremity PNF Patterns

    • Similar organization as the upper extremity with distinct diagonal movements for flexion and extension.

    Basic Procedures with PNF

    • Manual Contacts: Placing hands on agonist muscles for optimal stimulation during exercises.
    • Maximal Resistance: Applied resistance that is sufficient to challenge the muscle while allowing full range of motion without pain.
    • Therapist Positioning: Therapist aligns with the diagonal movement path to facilitate better execution.
    • Stretch Stimulus: Positioning limbs to lengthen muscles before contraction.
    • Stretch Reflex: Activation through a rapid stretch beyond the tension point of elongated muscles.
    • Normal Timing: Completion of distal movement patterns is encouraged midway through the diagonal motion to promote coordination.
