PNF Quiz

Which of the following is a proprioceptive neuromuscular facilitation stretching technique that is characterized by passively stretching the target muscle followed by active contraction of the muscle opposite the joint? hold-relax contract-relax agonist contraction hold-relax with agonist contraction

agonist contraction The proprioceptive neuromuscular facilitation (PNF) stretching technique of agonist contraction refers to the contraction of the muscle opposite the range-limiting target muscle. Therefore contraction of the agonist would result in lengthening of the shortened muscle (antagonist). This stretching technique is also known as dynamic range of motion and active stretching.

What type of muscle contraction is utilized when performing rhythmic stabilization? isometric isotonic isokinetic eccentric

isometric Rhythmic stabilization is used to increase range of motion and coordinate isometric contractions. The technique requires isometric contractions of all muscles around a joint against progressive resistance. The patient should attempt to relax and move into the newly acquired range of motion.

Which upper extremity proprioceptive neuromuscular facilitation pattern does this image depict? D1 flexion D1 extension D2 flexion D2 extension

D1 flexion Proprioceptive neuromuscular facilitation (PNF) is an approach used to establish gross motor patterns within the central nervous system. The upper extremity D1 flexion pattern consists of flexion, adduction, and external rotation of the glenohumeral joint, while the upper extremity D1 extension pattern consists of the opposite motions (i.e., extension, abduction, internal rotation).

What is the correct developmental sequence for skill acquisition? stability, controlled mobility, mobility, skill mobility, stability, controlled mobility, skill controlled mobility, mobility, stability, skill stability, mobility, controlled mobility, skill

mobility, stability, controlled mobility, skill Mobility, stability, controlled mobility, skill represents the correct sequence of motor control for skill acquisition. This sequence starts with the ability to initiate movement and eventually progresses to performing functional tasks and manipulating the environment.

Which of the following terms describes muscle activation of an involved extremity due to intense action of an adjacent muscle or group of muscles? chopping developmental sequence mass movement patterns overflow

overflow Overflow is a proprioceptive neuromuscular facilitation concept that refers to muscle activation of an involved extremity due to intense action of an adjacent muscle or group of muscles. Chopping is a neuromuscular technique that uses a combination of bilateral upper extremity asymmetrical patterns performed as a closed chain activity. Developmental sequence refers to a progression of skill acquisition from mobility to skill. Mass movement patterns are similar in concept to overflow, but refer specifically to the hip, knee, and ankle moving into flexion or extension simultaneously.

Which proprioceptive neuromuscular facilitation technique is characterized by a patient with hypertonia first being passively moved through the range of motion and then moving actively? dynamic reversals rhythmic stabilization rhythmic initiation combination of isotonics

rhythmic initiation Rhythmic initiation is a technique used to assist in initiating movement when hypertonia exists. Movement progresses from passive ("let me move you"), to active assistive ("help me move you"), to slightly resistive ("move against the resistance"). Movements must be slow and rhythmical to reduce the hypertonia and allow for full range of motion.

Which proprioceptive neuromuscular facilitation technique would be the most appropriate to improve mobility and reduce the effects of rigidity in a patient with Parkinson's disease? alternating isometrics rhythmic initiation rhythmic stabilization agonist reversal

rhythmic initiation Rhythmic initiation is indicated with hypertonicity, inability to initiate movement, motor learning deficits, and communication deficits

Which proprioceptive neuromuscular facilitation technique is performed while the patient performs isometric contractions? dynamic reversals stabilizing reversals rhythmic stabilization approximation

rhythmic stabilization Rhythmic stabilization utilizes alternating isometric contractions of the agonists, followed by the antagonists against resistance. Indications for the use of rhythmic stabilization include impaired strength and coordination, limitations in range of motion, and impaired stabilization control and balance.

Which of the following combined motions make up a D2 flexion upper extremity proprioceptive neuromuscular facilitation pattern? shoulder extension, abduction, external rotation shoulder flexion, adduction, internal rotation shoulder extension, adduction, internal rotation shoulder flexion, abduction, external rotation

shoulder flexion, abduction, external rotation The D2 flexion upper extremity proprioceptive neuromuscular facilitation pattern combines shoulder flexion, abduction, and external rotation. The diagonal patterns can be carried out unilaterally or bilaterally.

A proprioceptive neuromuscular facilitation technique that uses slow and resisted concentric contractions of agonists and antagonists around a joint without rest between reversals is termed: alternating isometrics rhythmic initiation rhythmic stabilization slow reversal

slow reversal Slow reversal is a technique used to improve stability, controlled mobility, and skill. Slow reversal is indicated with improving posture and general control of movement.
