- Stretching- PNF & METs
- ...
- PNF= Proprioreceptive Neuromuscular Facilitation
- 70-80% of muscle strength
- METs= Muscle Energy Techniques
- 10-20% of muscle strength
- PNF= Proprioreceptive Neuromuscular Facilitation
- Method
- 1. Passive pre- stretch, 10 secs
- 2. Ease back from stretch
- 3. Hold isometric cont. 6-10 secs. PIR= muscle stretched... RI- antagonist
- 4. Relax- passive stretch 30 secs
- 5. Repeat x 3-4
- 6. Hold final stretch 15-30 secs
- PIR vs RI
- RI less powerful
- PIR may be bad due to injury/ pain
- Best approach depends on healing stage
- Combination can be effective
- Golgi Tendon Organs
- PIR- Relaxation occurs in same muscle that increases tension
- PIR= Post isometric relaxation
- RI- Relaxation occurs in opposite muscle to that contracting
- RI= Reciprocal inhibition
- PIR- Relaxation occurs in same muscle that increases tension
