stretching Flashcards
what is mobility
ability to move ROM for functional abilites - functional ROM
assoc with joint integ and tissue extensibility
what is stretching
therapeutic maneuver to inc extensibility of soft tissues - imrpoving flexibility
elongating the structures that have adaptively shortened and became hypomobile
what is flexibility
ability to rotate a single joint or series of joints smoothly and easily through an unrestricted, pain-free ROM
exp dynamic flexibility
AROM - active muscle contraction and depends on contraction and tissue resistance
exp passive flexibility
PROM - external force and depends on muscle and connective tissue extensibility
prereq for AROM but does not ensure AROM
what are the contributing factors for hypomobility
prolonged immob
sedentary or habitual postures
postural or muscle imbalances
paralysis or weakness
compare contracture to tightness
both are adaptive shortening of muscle-tendon unit = LOM
contractures - almost complete loss
tightness - mild shortening lng
types of contracature
myostatic
pseudomyostatic
arthrogenic and periarticular
fibrotic and irreversible
exp myostatic contracture
shortened musculotendinous unit and can be resolved with stretching excericises easily
exp pseudomyostatic contrcture
hypertonicity assoc c CNS lesions, muscle spasm/guarding, pain
excessive resistance to passive stretch and can be reduced temoporarlily w neuromuscular inhib
exp arthrogenic and periarticular contracture
intra-articular pathology d/t adhesion, joint effusion, osteophyte formation - knee oa
connective tissue around joint becomes stiff
exp fibrotic and irreversible contracture
fibrotic - connective tissue becomes fibrous = adherence & fibrotic tissue
irreversible - permanent loss of extensibility s surgery
possible naman to stretch but vv hard to re-establish optimal tissue length
exp concept of selective stretching
stretching some muscles but allows LOM to some for stability or function - usually in pt’s c paralysis
SCI paraplegic - LOM of trunk motion but stretching on hams
what is overstretching
stretching beyond normal length of muscle and ROM of joint = hypermob
type of tissue that has elastic and plastic qualities
contractile and non-contractile
type of tissue that has visoelastic qualities
non-contractile only
what is the response of soft tissues to stretch
elastic - viscoelastic - plastic
what is elasticity
ablity of soft tissue to return to its pre-stretched resting length directly after a short duration stretch force
what is viscoelasticity
for non-contractile
time dependent - resists deformation initially and allows change in length if sustained then gradually return after stretch
what is plasticitiy
tendency of soft tissue to assume a greater length after stretch
grade 1 strain
microfailure - some ruptures at early plastic
