Study Notes
Warm-up Before Stretching
- Alignment and Stabilization: Crucial for effective stretching.
- Procedure:
- Stabilize the area proximal to the joint being stretched.
- Securely grasp the distal joint.
- Position the patient for stable alignment.
- Passively move the extremity through its full range of motion (ROM).
- Apply a slow, sustained, low-intensity stretch until firm tissue resistance is met.
- Maintain stretch slightly beyond this point for 30 seconds or more, allowing tissue to give.
- Gradually release tension while maintaining the stretched position.
- Repeat the sequence.
Home Exercise Program (HEP)
- HEP Components: Detailed written instructions or diagrams outlining exercises, repetitions, sets, hold times, intensity, frequency.
- Demonstrations: Instruct the patient and have them demonstrate the exercise on follow-up visits.
- Functional Activities: Incorporate exercises into functional activities to sustain improvements.
Contractile vs. Non-contractile Elements
- Contractile:
- Sarcomeres: Give (lengthen) with stretching.
- Decrease muscle guarding: Active inhibition techniques are beneficial.
- Sherrington's Laws:
- Reciprocal Inhibition: Antagonist muscle relaxation during agonist contraction.
- Autogenic Inhibition: Muscle relaxation following muscle contraction (PNF techniques: Hold-Relax, Contract-Relax).
- Golgi Tendon Organ (GTO):
- Located at the musculotendinous junction of extrafusal fibers.
- Senses muscle tension from passive stretching or active contraction.
- Inhibits the muscle it's embedded within, thereby reducing tension.
- Plays a role in Reciprocal Inhibition.
- Non-Contractile:
- Contractures: Conditions where tissues lose flexibility.
- Stress-Strain Curve: Shows how tissues respond to stress.
- Elastic vs Plastic Limits:
- Elasticity: Returns to original length after stretch.
- Plasticity: Maintains a lengthened state after stretch.
- GTO: Impacted by low-load/long-duration stretches.
- Creep: Gradual, sustained elongation of tissue over time.
- Low-load/long-duration stretch:
- Targets and reduces muscle tension via GTO.
- Effective for permanently lengthening adaptively shortened connective tissue.
- Dynasplint/Serial Casting: Used in cases of contractures to promote slow, controlled stretching.
- Hold Time with Exercise: Essential for static stretches, aiming for improving flexibility in connective tissues.
- Static Stretch: A method to increase flexibility.
- Positioning: Essential for optimal stretch outcomes.
