Agonistic Reversals (AR)
Controlled Mobility, Skill: An isotonic, concentric contraction performed against resistance followed by alternating concentric and eccentric contractions with resistance. Requires use in a slow and sequential manner. May be used in increments throughout range to attain maximum control.
Alternating Isometrics (AI)
Stability: Isometric contractions are performed alternating on one side of the joint to the other side without rest. Emphasizes endurance or strengthening
Contract-Relax (CR)
Mobility: Used to increase ROM. As extremity reaches EROM, pt performs a maximal contraction of the antagonistic muscle group while the therapist resists movement for 8-10 seconds with relaxation to follow. Technique is repeated until no further increases in ROM occur.
Hold-Relax (HR)
Mobility: Isometric contraction used to increase ROM. The contraction is facilitated for all the mm groups at the EROM. Relaxation occurs and the extremity moves through the acquired ROM until no further ROM occurs. Used often for pts that present with pain.
Hold-Relax Active Movement (HRAM)
Mobility: Used to improve initiation of movement to muscles tested at 1/5 or less. Isometric contraction is performed once extremity is passively placed into a shortened range within the pattern. Can use Overflow and facilitation techniques to assist. After relaxation, the extremity is immediately moved into a lengthened position of the pattern via quick stretch. The pt is asked to return to the shortened position through an isotonic contraction.
Joint Distractions
Mobility: A proprioceptive component used to increase ROM around a joint. Consistent manual traction is provided slowly and usually in combination with mobilization techniques. Can also be used in combination with quick stretch to initiate movement.
Normal Timing (NT)
Skill: 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 the pattern produces a coordinated movement of all components.
Repeated Contractions (RC)
Mobility: Used to initiate movement and sustain contraction through the ROM. Used to initiate a movement pattern, throughout a weak movement pattern, or at a point of weakness in a movement pattern. PT provides a quick stretch followed by isometric or isotonic contractions.
Resisted Progression (RP)
Skill: To emphasize coordination of proximal components during gait. Resistance is applied to an area such as the pelvis, hips, or extremity during gait in order to enhance coordination, strength, or endurance.
Rhythmic Initiation (RI)
Mobility: To assist in initiating movement when hypertonia exists. Movement progresses from passive, to active assistive, to resisted. Movement must be slow and rhythmical to reduce hypertonia and allow for full ROM.
Rhythmical Rotation (RR)
Mobility: To decrease hypertonia by slowly rotating an extremity around. Relaxation of the extremity will increase ROM.
Rhythmical Stabilization (RS)
Mobility, Stability: To increase ROM and coordinate isometric contractions. Requires isometric contractions of all mm around a joint against progressive resistance. The pt should relax and move into the newly acquired ROM and then repeat. If stability is the goal, it should be applied as a progression from Alternating isometrics in order to stabilize all mm groups simultaneously around the specific body part.
Slow Reversal (SR)
Stability, controlled mobility, skill: Slow and resisted concentric contractions of agonists and antagonists around a joint without rest btw reversals. Used to improve control of movement and posture.
Slow-Reversal Hold (SRH)
Stability, controlled mobility, skill: Using slow-reversal with the addition on an isometric contraction that is performed at the end of each movement and posture
Timing for Emphasis (TE)
Skill: To strengthen the weak component of a pattern. Isotonic and isometric contractions produce overflow to weak muscles.
