Techniques of PNF
Slow Reversal
Slow Reversal Hold
Hold Relax
Contract Relax
Slow Reversal
The slow reversal techinque, involves alternate, slow rhythmical concentric contractions of all the components of agonistic and antagonist patterns without relaxation between reversals
Slow Reversal Hold
This technique varies from SR in that a gradually applied isometric contraction is introduced at the end of he range of movement pattern.
Hold Relax
An isometric contraction of all of the components of the range limiting or antagonistic pattern is elicited usually at the point of limitation of the available range. The isometric contraction is gradually maximized over a period of seconds and it is followed by a command to relax slowly. The limb actively moves against minimal resistance trough the newly gained range to the new point of limitation.
Contract Relax
With the joint at the point of limitationthe subject is asked to turn and pull of turn and push as much as possible. The result is an isotonic contraction of the rotary component and an isometric contraction of the other two components of the antagonistic pattern. Unlike HR, however the rotation is allowed, not gradual and the release is abrupt.
Elements of PNF
Manual Contacts (MC) Verbal Commands (VC) Resistance (Manual, theraband, weights) Traction/Approximation Prolonged Stretch (PS) Quick Stretch (QS)
Cephalocaudal development
Motor abilities first occur in the face, head and neck and then progress to the upper trunk then to the lower trunk.
Proximal to Distal Direction of Devlopment.
UE begins promiall in the scapula and shoulder and progress distally to the elbow and hand.
LE motor control progress from the pelvis and hip to the knee and ankle.
The Stages of Motor Devlopment
Mobility
Stability
Controlled Mobility
Skill
Sequencing of Posture and Activities
Prone Sequence
Supine Sequence
Prone Sequence
Pivot prone Prone on elbow Reaching Prone on Hands Quadricped
Supine Sequence
Supine Flexion Rolling Sitting Reaching Standing Walking
Proprioception
The body’s ability to transmit position sense, interpret the information and respond consciously or unconsciously to stimulation through appropriate execution of posture and movement.
Optimal Training Rates
Cardiorespiratory development occurs when the heart is working between 40-85% of HRR
Increases in VO2Max are accelerated when the heart is working closer to 85% of HRR
Phases of Rehbilitation
Protection Phase
Controlled Motion Phase
Return to Function Phase
Protection Phase
Educate the patient Decrease acute symptoms. -address any potential bias Use passive support as necessary. -Use passive support as necessary.
Teach awareness of pelvic position and movement
“Neutral Position”
demonstrate safe postures
Initiate neuromusclular activation and control of stabilizing muscles
Teach safe performance of ADLs
