Exam 3: PNF Flashcards
What does PNF stand for?
Proprioceptive Neuromuscular Facilitation
Describe what the term “proprioception” indicates in the definition of PNF?
Stimuli produced within an organism by movements of its own tissues that is stimulated by some aspect of muscle length or tension, joint angle, and head position
Describe what the term “neuromuscular” indicates in the definition of PNF?
Pertaining to nerves and muscles
Describe what the term “facilitation” indicates in the definition of PNF?
Promotion or quickening of natural processes, more specifically the effect produced in nerve tissue by the passage of an impulse that lowers the resistance to transmission so that a subsequent stimuli may be elicited more easily
What are the five main principles of the foundations of PNF?
- Target the whole person rather than a specific problem or body segment
- Mobilize reserves of untapped potential
- Positive approach to reinforce what a patient can do at a physical and physiological level
- Achieve highest level of function though most efficient movement combinations
- Integrate the principles of motor control and learning
What is the systems model of motor control, and what did it lead to the creation of with PNF?
Functional movement based on the interaction of many systems. Helped to created the stages of motor control
What are the stages of motor control?
- Mobility
- Stability
- Controlled mobility
- Static dynamic
- Skill
What is the general concept of direct PNF techniques?
Apply activities and techniques to the most impaired areas
What is the general concept of indirect PNF techniques?
Apply activities and techniques to less involved areas create movement and synergies that will develop movement in the more involved areas
What two things should be considered when determining the appropriate activity and technique for PNF?
The personal environment and context. What is the posture or movement that is functionally necessary for the patient
What are the three parameters for PNF intervention?
- Frequency
- Duration
- Intensity
What is the principle of “afterdischarge”?
The effect of the stimulus continues after the stimulus is removed. As the strength and duration of the stimulus increased, the afterdischarge will increase as well
What is the result of afterdischarge?
Feeling of increased power that comes after the maintained static contraction
What is temporal summation?
A succession of weak stimuli to cause excitation
What is spatial summation?
Weak stimuli is simultaneously applied to different areas of the body to reinforce each other and cause excitation
What is irradation?
Spreading and increased strength of a response that occurs when either the number of stimuli or the strength of the stimuli is increased
What is successive induction?
An increased excitation of the agonist muscles follows the stimulation of their antagonists
What is reciprocal innervation or reciprocal inhibition?
Contraction of the muscles is accompanied by the simultaneous inhibition of their agonists as a means of coordinating movement
What are the four categories within PFN treatment that the therapist has to consider?
- Learning sequence
- Diagonal pattern
- Elements
- Techniques
What is a learning sequence?
The organization of postures and movements based on normal and typical growth and development. Is not a linear approach, and will reflect the development of motor abilities
What are diagonal patterns of movement?
Highly sophisticated set of movement patterns for the extremities and trunk which are based on normal and typical patterns of movement observed in functional activities
True or False: Diagonal patterns of movement incorporates movement in multiple planes and are based on normal and typical muscle synergies
True
How are extremity patterns named?
By what is happening at the proximal joint
The Ulnar Thrust pattern is a combination of what two movements?
Proximal D1 flexion and distal D1 extension
The Ulnar Withdrawal patterns is a combination of what two movements?
Proximal D1 extension and distal D1 flexion
The Radial Thrust pattern is a combination of what two movements?
Proximal D2 extension and distal D2 flexion
The Radial Withdrawal pattern is a combination of what two movements?
Proximal D2 flexion and distal D2 extension
What are the four combinations of extremity patterns?
- Bilateral symmetrical
- Bilateral asymmetrical
- Symmetrical reciprocal
- Asymmetrical reciprocal
What is the bilateral symmetrical combination pattern?
Same diagonal and same direction
What is the bilateral asymmetrical combination pattern?
Different diagonals in the same direction
What is the symmetrical reciprocal combination pattern?
Same diagonal in different directions
What is the asymmetrical reciprocal combination pattern?
Different diagonals in different directions
