Techniques of PNF

Slow Reversal
Slow Reversal Hold
Hold Relax
Contract Relax

2

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

3

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.

4

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.

5

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)

7

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.

8

The Stages of Motor Devlopment

Mobility
Stability
Controlled Mobility
Skill

9

Sequencing of Posture and Activities

Prone Sequence
Supine Sequence

10

Prone Sequence

Pivot prone
Prone on elbow
Reaching
Prone on Hands
Quadricped

11

Supine Sequence

Supine Flexion
Rolling
Sitting
Reaching
Standing
Walking

12

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.

13

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

14

Phases of Rehbilitation

Protection Phase
Controlled Motion Phase
Return to Function Phase

15

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

16

Controlled Motion Phases

Educate the patient
Progress awareness and control of spinal motion
Increase mobility in restricted regions
Teach techniques to develop neuromuscular control, strength and endurance.
develop cardiopulmony endurance.
Teach techniques of stress relief
Teach safe body mechanics and functional adaptations

17

Static Stability

dependent on the material properties of the system.

dependent upon the geometry of the system

18

Dynamic Stability

Postural Control
Anticipatory postural adjustments
Postural Reactions
