Stabilize proximally, grasp distally

A stretching technique where you stabilize the body part closer to the center of the body, then grasp the part farther away.

Passive stretching

Stretching a muscle or joint by an outside force, not by contracting the muscle itself.

Contractile elements

Parts of a muscle that contract to cause movement.

Non-contractile elements

Parts of a muscle that do not contract to cause movement, but contribute to the overall flexibility.

What is the goal of proximal stabilization during stretching?

Proximal stabilization ensures the part of the body closest to the center remains fixed, preventing unwanted movement and allowing for a focused stretch on the target muscle or joint.

What are contractile elements in muscle stretching?

Contractile elements are the parts of the muscle responsible for contraction, such as the sarcomeres, and they lengthen primarily through relaxation or inhibition.

What are non-contractile elements in muscle stretching?

Non-contractile elements are the connective tissues surrounding muscles, like tendons and fascia, which lengthen primarily through remodeling.

How does the Golgi Tendon Organ (GTO) influence stretching?

The GTO senses tension in the muscle and inhibits muscle activity when excessive tension is detected, contributing to relaxation and increased range of motion.

What is autogenic inhibition?

Autogenic inhibition occurs when a muscle contracts and then relaxes, leading to a greater relaxation in the muscle. This technique is used in stretching to increase range of motion.

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.
