Term
Agonistic Reversals
Definition
isotonic concentric contraction against resistance
followed by alternating concentric and eccentric contractions with resistance

used in a slow and sequential manner
Term
Alternating isometrics
Definition
isometric contractions performed by muscles on alternating sides of the joint without rest
Term
Contract-Relax
Definition
at end-range, pt performs max contraction of antagonist mm, resisted by therapist for 8-10 sec
Term
Hold-Relax
Definition
isometric contraction of all mm groups at the limiting point in the ROM
Term
Hold-Relax Active Movement
Definition
(for mm groups tested at 1/5 or less)

Isometric contraction performed with mm in shortened range;
upon relaxation, extremity is immediately moved into a lengthened position with a quick stretch
Term
Joint Distraction
Definition
proprioceptive component used to incr ROM;
consistent manual traction provided slowly
Term
Normal Timing
Definition
performed in distal to proximal sequence

proximal components are restricted until distal components are activated and initiate movement
Term
Repeated Contractions
Definition
therapist provides quick stretch followed by isometric or isotonic contractions
Term
Resisted Progression
Definition
Resistance applied to proximal component (hips, pelvis, etc) during the gait cycle to enhance coordination/strength/endurance
Term
Rhythmic Initiation
Definition
movement progresses from
passive >> active assistive >> slightly resistive

must be slow and rhythmical (reduce hypertonia)
(used to assist in initiating movement when hypertonia exists)
Term
Rhythmical Rotation
Definition
slowly passively rotating an extremity around longitudinal axis (reduce hypertonia)
Term
Rhythmic Stabilization
Definition
isometric contractions of all mm around a joint against progressive resistance

(should be applied as a progression from Alternating Isometrics)
Term
Slow Reversal
Definition
slow and resisted concentric contractions of agonists and antagonists without rest
Term
Slow Reversal Hold
Definition
slow reversal with the addition of an isometric contraction at the end of each movement
Term
Timing for Emphasis
Definition
isotonic and isometric contractions producing overflow to weak muscles

(used to strengthen weak component of a motor pattern)
