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.
