TermDefinition
Range of Motion (ROM)
The amount of movement possible at joint.
Flexibility
Ability of muscle to lengthen, allowing one joint (or more than one joint in a series) to move through of a ROM.
ROM & flexibility
ROM & flexibility are related but not equal.
Elasticity
Ability to return to normal length.
Viscosity
Resistance to change from outside force.
Viscoelasticity
Resistance to change, inability to completely return to its former state after changing shape.
Plasticity
Allows permanent change.
Muscle spindles
Sensitive in muscle length.
Golgi Tendon Organs (GTO)
A protective mechanism, less sensitive to stretch & more sensitive to contraction and tension.
Fast stretch
If stretch quickly, muscle contracts (muscle spindle).
Slow stretch
If stretch applied slowly, GTO inhibits muscular contraction.
Benefits of stretch
Increase ROM and maintain available ROM.
Benefits of stretch
Improve posture.
Benefits of stretch
Reduce muscle soreness.
Benefits of stretch
Prevent musculoskeletal injuries.
Benefits of stretch
Provide relaxation and relieve neuromuscular tension.
Benefits of stretch

Stretching cautions
Posture is important.

Stretching cautions
Flexibility is joint specific.
Stretching protocol
Assistant must constantly remind client to inform them if at any time during the stretch they can move further into the ROM.
Stretching protocol
Assistant starts moving the joint through the ROM to the point of stretch or until the client tells you to hold/stop.
Stretching protocol
At this point hold your position and start your count 1-1000, 2-1000, 3-1000, etc.
Stretching protocol
Ask the client if you can go further.
Stretching protocol
If they say yes, move further into the ROM until the client tells you to stop or hold. At this point, hold your position and start counting where you left off.
Stretching protocol
If the client says no, hold the same position and continue count.
