flexibility and factors that impact movement Flashcards
flexibility
ability of a joint to move through a full ROM in a single plane
ROM
full movement potential of a joint measured by linear or angular distance beterrn two limits
mobility
movement ability during multi-joint actions which rely on the coordination of several muscle groups and body segments
flexibility and mobility are ___ but not ____
interrelated
synonymous
a client may have goof flexibility at a single joint, but poor ____ in the same area
mobility
differences between bilateral joint movement capabilities depend upon several variables including
genetic variations
strength, balance
connective tissue discrepancy
joint injury
activity participation
activation issues
resting postural alignment
asymmetrical postures created by bilateral ROM disparities increase the risk for
injury and promote faulty movement patterns
benefits of flexibility
increased movement range
reduction in the rate of functional decline
postural symmetry
stress reduction
reduced tension
muscle relaxation
reduced incidence of muscle cramps
reduced risk of injury
relief of muscle pain
improved quality of life
activities that emphasize flexibility reduce musculoskeletal stress via
alleviation of tension
reduction of psychomotor distraction
improved state of overall relaxation
hyper mobility
movement capacity of a joint beyond the normal ROM
hypermobility compromises
stability
soft tissue in the human body include
muscle and fascia
tendons and ligaments
skin, fat, collagen
synovial membranes
nerves and blood vessels
elasticity
property that allows stretched tissue to return to its original form
plasticity
ability of tissue to become permanently deformed or elongated after being stretched
viscosity
variable fluid resistance to stretch within soft tissue, can be reduced with warm up
the collagen content of a tissue primarily determines
extensibility, capability to be stretched
joint capsule tissue, ligaments and fascia have ___ collagen content
high
elastin fibers allows for
greater stretching and deformation potential
contributors to movement resistance:
joint capsule __%
muscle fascia __%
tendon __%
skin __%

high muscle/joint stress can cause _____ which can manifest as
myofascial restriction
movement dysfunction, trigger points, pain
restriction and trigger points can be alleviated using different treatments, including
stretching
manual massage
thermotherapy
electrotherapy
acupuncture
pressure rolling using foam rollers and related devices
three primary proprioceptors are used for
neural management of ROM
muscle spindles
receptors that identify stretch length/speed
muscle spindles not activated with ____ but will activate to _____
slow, controlled stretches
to prevent overstretch
golgi tendon organs located in the
musculotendinous junction
golgi tendon organ contributes to
autogenic inhibition of muscle to protect from a tear or overstretch
autogenic inhibition
reduction in muscle excitability in response to high tension
autogenic inhibition self induced by
the muscle due to negative feedback signaled by activation of proprioceptors
