Mobility and Flexibility Training Flashcards
Flexibility refers to
the ability to move a joint through an unrestricted, pain free ROM
Musculotendinous unit elongates as the body segment moves through the ROM
Dynamic flexibility refers to
the active ROM of a joint and is dependent upon the amount of tissue resistance met during active movement
Passive flexibility is the
degree to which a joint can be passively moved through available ROM and is dependent on the extensibility of the muscle and CT around the joint
Stretching
therapeutic technique that lengthens shortened soft tissue structures and increases ROM
Ballistic stretching
High intensity, very short duration, “bouncing” stretch
By contracting the opp mm group, the pt uses body weight and momentum to elongate the tight muscle
Considered unsafe!
Prolonged low intensity mechanical stretching
An external force (5 to 15 pounds to 10% BW) is applied by positioning a pt with weight pulley and traction systems
Maintained 20-30 minutes of can be several hours
Dynamic splint does what
Maintains limb position at end range
typically left for 8-10 hours
A serial cast does what
Maintains limb position at end range
typically cast applied for 5-7 days
Active stretching is what
voluntary, unassisted movement by the pt provides the stretch force to the joint
15-30 sec hold
Facilitated stretching is what
Techniques in which the pt reflexively relaxes the mm to be elongated prior to or during the stretching technique (like PNF hold relax)
A quick stretch to a muscle stimulates
the alpha motoneurons and facilitates mm contraction via the monosynaptic stretch reflex
Myostatic contracture
involves a musculotendinous unit that has adaptively shortened with loss of ROM
usually occurs without specific tissue pathology and in two joint mm like hamstrings
Adhesions
abnormal union of membranous tissue resulting from injury or inflammation
