PNF Flashcards
What is the purpose/definition of agonistic reversals (AR)?
-Controlled mobility
-Skill of proximal dynamic stability
Definition: an isotonic concentric contraction performed against resistance followed by alternating concentric and eccentric contractions with resistance.
-Requires use in slow and sequential manner
-May be used in increments throughout the range to attain maximal control
What is the purpose/definition of alternating isometrics?
-Stability
-Strength
Definition: isometric contractions are performed alternating from muscles on one side of the joint to the other side without rest
-emphasizes endurance and strengthening
What is the purpose/definition of contract-relax?
-Mobility: increased ROM
Definition: as extremity reaches the point of limitation, pt performs a maximal contraction of the ANTAGONISTIC muscle group. Therapist resists movement for 8-10 sec with relaxation follow.
-Repeated until no further ROM are noted during session.
-stronger contraction than hold-relax technique
What is the purpose/definition of hold-relax?
-Mobility: increased ROM
Definition: Contraction facilitated for all muscle groups at the limiting point in ROM. Relaxation occurs and the extremities move through the newly acquired range to the next point of limitation until no further increases in ROM occur.
-Used for patients that present with pain
-Still uses antagonistic muscle, just a more gentle contraction
What is the purpose/definition of hold-relax active movement?
-Mobility: initiate movement (in muscle groups with strength 1/5)
Definition: isometric contraction is performed once the extremity is passively placed into a shortened range within the pattern. Overflow and faciliation may be used to assist the contraction. Upon relaxation, the extremity is immediately moved into a lengthen position of the pattern with a quick stretch. Pt asked to return the extremity to the shortened position through and isotonic contraction
What is the purpose/definiton of joint distraction?
-Mobility: increased ROM and initiate movement
Definition: Proprioceptive component. Consistent manual traction is provided slowly and usually in combination with mobilization techniques.
-Can also be used in combo with quick stretch to initiate movemnt
What is the purpose/definition of normal timing?
-Skill: distal functional movement
Definition: used to improve coordination of all components of a task. Performed in a distal to proximal sequence. Proximal components are restricted until the distal components are activated and initiate movement.
-Repetition of pattern produces a coordinated movement of all components
What is the purpose/definition of repeated contractions?
-Mobility: initiate movement
-Strength
Definition: used to initiate movement and sustain a contraction through the ROM. Used to initiate a movement pattern or at a point of weakness withing a movement pattern. Therapist provides a quick stretch followed by isometric or isotonic contractions
-Superimposed quick stretch on movement pattern
What is the purpose/definition of resisted progression?
-Skill: distal functional movement
-Strength
Definition: used to emphasize coordination of proximal components during gait. Resistance is applied to an area such as the pelvis, hips or extremity during the gait cycle in order to enhance coordination, strength or endurance
What is the purpose/definition of rhythmical rotation?
-Mobility: increased ROM and initiate movement
Definition: passive technique to decrease hypertonia by slowly rotating an extremity around the longitudinal axis. Relaxation of the extremity will increase ROM
What is the purpose/definition of rhythmic stabilization?
-Mobility: increased ROM
-Stability
Definition: used to increase ROM and coordinate isometric contractions. Requires isometric contraction of all the muscles around a joint against progressive resistance. Pt should relax and move into the newly acquired range and repeat the technique
-if stability the goal, RS applied as a progression from AI in order to stabilize all muscle groups simultaneously around the specific body part
What is the purpose/definition of slow reversal?
-Stability
-Controlled mobility
-Skill: distal functional movement
Definition: technique of slow and resisted concentric contractions of agonists and antagonists around a joint without rest between reversals.
-used to improve control of movement and posture
What is the purpose/definition of timing for emphasis?
-Skill: distal functional movement
-Strength
Definition: used to strengthen the weak component of a motor pattern. Isotonic and isometric contractions produce overflow to weak muscles
What is the purpose/definition of rhythmic initiation?
-Mobility: initiate movement
Definition: used when hypertonia exists. Movement progresses from passive, to active assistive, to slightly resistive. Movements must be slow and rhythmical to reduce the hypertonia and allow for full ROM.
What is the purpose/definition of slow reversal hold (SRH)?
-Stability
-Controlled mobility
-Skill
Definition: Using slow reversal with the addition of an isometric contraction that is performed at the end of each movement to gain stability
