Question Answer
Rhythmical Rotation (RR) Mobility - Stage I Completely passive motion, used with hypertonia. Therapist rotates back and forth along long axis for about 10 seconds. May be followed by passive or active movement into new range.
Rhythmic Initiation (RI) Mobility - Stage I Used with hypertonus. Movement through a pattern moves from passive to active-assisted to active to slightly resisted.
Slow Reversal (SR) - aka Dynamic Reversals or Isotonic Reversals Multi-faceted Mobility, Stability, Controlled Mobility - Stages I, II, III Alternating, slow, rhythmical concentric contractions of the agonistic and antagonistic patterns without relaxation between reversals. Isotonic in each direction - you change direction of resistance & hand placement.
Slow Reversal Hold (SRH) - aka Dynamic Reversals, Hold Multi-faceted Mobility, Stability, Controlled Mobility - Stages I, II, III Same as SR except that a gradually applied isometric contraction is introduced at the end of range of the movement pattern, prior to reversing the pattern. Isometric at end of range - you change direction of resistance & hand placement.
Repeated Contractions (RC) - aka Repeated Contractions Multi-faceted Repeated contractions are applied to the muscles during the pattern (in the opposite direction) for facilitation. Like little "quick stretches" throughout.
Hold Relax Active Movement (HRAM) - aka Replication - applied to agonist in shortened range r/i reciprocal inhibition & agonist recruitment Mobility - Stage I Used with hypotonia or weakness. Pt. holds a graded, manually resisted isometric contraction in mid- to shortened range. Pt. then told to relax, moved into lengthened position, and a quick stretch is applied. Pt. actively moves through the range against RCs. PT may assist, track, or resist.
Hold Relax (HR) - applied to antagonist in lengthened position r/i autogenic inhibition Mobility - Stage I Used with mm tightness on one side of a joint and/or pain. An isometric contraction of antagonists to movement is elicited. Once maximized, pt. relaxes and then therapist moves patient into newly gained range. Repeat until no range increases occur.
Contract Relax (CR) Mobility - Stage I Used with decreased ROM on one side of a joint. Similar to HR except, with the joint at the point of limitation, the pt. turns and pushes (or pulls) against resistance that blocks all except the rotatory component of the antagonist mm movement pattern.
Assist to Position Technique wherein the pt. has the range of motion (mobility) to assume a position but is not able to do so independently. He/she may be assisted to position in order to begin working on Stage II (stability).
Rhythmic Stabilization (RS) - aka Isometric Stabilizing Reversals Mobility - Stage I Stability - Stage II Used with pain. Isometric contractions of both agonist and antagonist patterns are alternately elicited by the therapist. Relaxation is not permitted as manual contacts are altered. Build up to maximal contraction and then relax.
Shortened Held Resisted Contraction (SHRC) Stability - Stage II Pt. is placed in a shortened, non-weightbearing position (such as side lying) and isometric contractions are resisted by the PT.
Alternating Isometrics (AI) - aka Isometric Stabilizing Reversals Stability - Stage II Isometric resistance of agonists followed by isometric resistance of antagonists.
Agonist Reversals (AR) - Combination of Isotonics Multi-faceted Controlled Mobility in preparation for Skill Stages III-IV Emphasizing either the flexion or extension portion of a pattern, the patient moves isotonically through the range. Resistance is provided to the concentric and then to the eccentric movement several times. Your hands don't move.
Timing for Emphasis (TE) Multi-faceted Controlled Mobility in preparation for Skill Stages III-IV A strong isometric contraction is elicited in the part of the range where the pt. is strong in order to facilitate overflow to the weaker components of the pattern. Using irradiation!
Resisted Progression (RP) - aka Resisted Gait Progression Skill - Stage IV Resistance to progression (in prone, quadruped, or upright positions) to increase strength and endurance and to enhance normal timing. Manual contacts on part to be emphasized.
Hold Relax Agonist Contraction (HRAC) - applied to agonist in shortened range r/i reciprocal inhibition & agonist recruitment Mobility - Stage I Used with mm tightness on one side of a joint and/or difficulty initiating movement. An isometric contraction of antagonists to movement is elicited. Once maximized, pt. relaxes and then moves actively against minimal resistance through newly gained range. Repeat until no range increases occur.
