muscle resting tension Flashcards
the ability of a skeletal muscle to shorten with force
contractility
the capacity to respond to stimulus
excitability
the ability of a muscle and its associated fascia to undergo lengthening deformation during the movement of a joint through its anatomic range
extensibility
the ability of skeletal muscle to recoil to their original resting length after they have been stretched
elasticity
showing both viscous/plastic and elastic behaviour
viscoelasticity
contration type: tension generated is insufficient to overcome the external load on the muscle and the muscle fibres lengthen as they contract
eccentric contraction
contraction type: tension in the muscle remains constant despite a change in muscle length
isotonic contraction
contraction type: muscle tension is sufficient to overcome the load, and the muscle shortens as it contracts
concentric contraction
the extent to which a muscle conforms to the expected anatomical and biological norms
muscle integrity
the resting tension and responsiveness of muscle to passive elongation or stretch
muscle tone
decrease in mobility/movement/restricted motion of a joint or body part
hypomobility
increase in mobility/movement/restricted motion of a joint or body part
hypermobility
Usually the results of brain lesions UMN, brainstem lesions, and basal cell ganglia lesions
hypertonicity
when soft tissue dysfunction is present, can limit the available ROM and change the quality of movement. can be restrictive, pathological, and psychological
barriers
a condition in which a muscle is elongated beyond physiological neutral but not beyond the normal ROM
stretch weakness
the most severe form of muscle tightness. overused muscle shortens over time, changing the muscle’s length-tension curve and becoming more readily activated and weakened over time
tightness weakness
the passive tonus or tension of skeletal muscle that derives from its intrinsic molecular viscoelastic properties
myofascial tone
the vital low-level, passive tension, and resistance to stretch that contributes to maintain postural stability
postural tone
tension developed by the contractile element
active tension
the 3 contractile contributors to muscle resting tension
spasm, trigger points, umrt/holding patterns
the 4 biomechanical contributors to muscle resting tension
water, connective tissue, myofibril, adipose
what 2 forms are water in as a contributor to muscle resting tension
free or bonded
