Stretching

Any therapeutic intervention that increases the mobility of restricted soft tissues

Nerve is able to move without adverse stress due to:

Arrangement of the nervous system (spinal cord, nerve roots, and plexus - the movement is dissipated throughout the system and neural ischemia is avoided) Connective tissues (helps to absorb tensile forces) Perineurium (primary guard against excessive tension and allows for 18-22% strain before failure, due to its elastic properties and strength)

Elastic Range

Change in stress results in a proportional change in strain

Principles of neural mobilization treatment

Goal - neurodynamic exercise is to maximize the excursion of that nerve while minimizing the strain Intensity is dependent on irritability of the tissue, the pt's response, and the change in symptoms Technique/application of neurodynamic mobilization is performed relatively symptom free in a slow rhythmic and oscillatory motion so the therapist nudges the stretch and then backs off *not a static prolonged hold like in static stretching Link what you find from the neurodynamic testing to the neurodynamic treatment

Stress-Relaxation

If a subfailure load is applied to a viscoelastic tissue, and kept constant, there's a gradual decrease in the force required to maintain the amount of deformation. This is due to the viscoelastic nature of the connective tissue and redistribution of water content within the tissue

Exercise Prescription for Strength Training

Novice - Intermediate 60-70% 1 RM Advanced - Experienced >80% 1 RM Increased load will more effectively increase strength 8-12 Reps; 1-3 sets (3 sets are most effective) Rest in between sets: 2-3 min; 2-10 sec rest b/w sets may allow increased loads Velocity (slow-mod): untrained individuals start at 1-2 sec; increased tension time may increase strength gains
