What is flexibility
Ability to move a joint or series of joints easily through an unrestricted, pain free ROM.
What is dynamic flexibility
AROM dependent on muscle contraction and tissue resistance
What is passive flexibility
PROM dependent on extensibility of muscle and connective tissue
What are the types of stretching?
manual, mechanical, self-stretching, neuromuscular, muscle energy, joint mobilization, soft tissue mobilization, neural mobilization
What are some indications for the use of stretching?
- Increase flexibility & ROM
- reduce risk of injury
- reduce postexercise muscle soreness
- restrict deformities due to lack of movement
- increase muscle strength and reduce shortening of tissue
What are contraindications for stretching?
- joint limitation due to bony block
- recent fracture or incomplete bony union
- inflammation or infection in tissue
- sharp acute pain w/ joint movement
- hematoma or tissue trauma
- hypermobility already exists
- shortened sof tissue provides necessary joint stability
- shortened tissue enable paralysed patient to perform special functions
What is viscoelasticity?
tissue initially resists change but will deform after sustained stretch force. mostly happens in connective tissue
What is plasticity?
tissue assumes a new and greater length after stretch is removed
What are the 5 stretching techniques?
- proprioceptive neuromuscular facilitation
When is the Golgi tendon stimulated
with excessive stretch or contraction
What are some advantages having a patient due static stretching?
- decrease chance of causing injury
- eae of instruction
- patient can perform independently
What are some advantages of ballistic stretching?
- modfied to be sport specific
- better prepare athlete for sporting event of high velocity, ballistic and violent activity
What is autogenic inhibition?
relaxation of the affected muscle elicited through contraction (GTO)
What is reciprocal inhibition
relaxation of the affected muscle elicited through contraction of the opposite muscle (agonist muscle)
What type of contraction is used during a contract-relax stretching technique?
What type of contraction is used during a hold-relax stretching technique?
What are the parameters for mechanical stretching?
Light resistance for a long period of time 20-60 minutes in stretch position
What are the 3 commonly used PNF stretching techniques?
