Flexibility & Postural Defects
The ability of a joint to move through its full range of
motion
Types of Stretching Techniques Ballistic Stretching: Stretching the muscle
suddenly in a repeated bouncing movement
- elicits Myotatic Reflex (_____________)
Static Stretching: Slowly stretching the muscle and then holding the stretch position without bouncing
- elicits Inverse Myotatic Reflex (_____________________________)
Stretching & Muscle Reflexes
Myotatic Reflex (Stretch Reflex) Muscle spindles, specialized
sensory receptors, located among muscle fibers detect and respond to the _______ and ______________ of stretch on a muscle - Sends message to spinal cord, which sends a message back to the muscle to __________
The Myotatic Reflex (Stretch Reflex)
Stretching & Muscle ReflexesInverse Myotatic Reflex (Stretch Reflex
Inhibition) Golgi Tendon Organs, specialized sensory
receptors, located within tendons detect and respond to _______ caused either by muscle contraction or by being stretched- Sends message to spinal cord, which sends a message back to the muscle to _______
Inverse Myotatic Reflex (Stretch Reflex Inhibition)
Proprioceptive Neuromuscular facilitation (PNF)
Incorporates the stretch reflex inhibition to better facilitate stretching
Contract-relax-stretch pattern
Developing Flexibility Frequency: __ to ___ days/week Intensity: Stretch to the point of
discomfort, not pain Duration: Hold stretch position __
to __ seconds. Perform approx. 4 reps of each stretch
Low Back Pain Low back pain can result from
traumatic injuries, but is more often the long-term result of “weak” and “inflexible” muscles, poor posture, or poor body mechanics.
Good Posture vs. Lordosis
Lordosis-Excessive anterior curvature of the lumbar spineWeak Muscles ________________ ________________
Inflexible Muscles ________________ ________________

Check for Lordosis Anterior Superior Iliac Spine Posterior Superior Iliac Spine
Strengthen the Weak Muscles:Abdominals Hip Extensors
Crunch Bridge
Stretch the Inflexible Muscles Low Back Ext. Hip Flexors
Knees-to-Chest Lunge
Kyphosis-Excessive ________ curvature of the thoracic spine

Scoliosis- Lateral Curvature of the Spine
Scoliosis 80% of scoliosis is idiopathic Other causes include, congenital
spinal deformities, neuromuscular problems, leg length discrepancies, cerebral palsy, spina bifida, muscular dystrophy, etc.
Most common: Adolescent 10-18 yrs Affects 2% women, .5% men
Scoliosis – Signs & Testing Unequal shoulder or
scapula (prominent) distance between
arm and side Uneven waist ______________
(Adam’s Forward Bend Test)
Check for Scoliosis
Need for Early & Regular Screening at Home Degree of curve can progress as
much as ___ to ___ degrees per month.
If degree of curve exceeds 40 degrees then surgical intervention is usually required.
