tender
a tissue is strained leading to recruitment of pain receptors within that tissue that respond by reflexive contraction. which pain model
nociceptive
MoA of counterstrain in which excessive stretch of primary spindle induces protective contraction of extrafusal fibers
proprioceptive
counterstrain theory in which agonist is shortened in response to strain
nociceptor
countesrtrain theory in which the antagonist muscle is shortened
proprioceptive
four phases of counterstrain
relaxation
reset fo spindle fibers and nociceptors
washout
slow return to neutral
phase of counterstrain in which the affected tissue is shortened in three plaines
relaxation
phase of counterstrain where the primary and secondary endings of muscle spindle stretch receptors (but not golgi tendon organs) are reset
spindle reset
when does metabolic washout begin to occur
10-15 seconds after optimal position is achieved
when does peak washout occur
approximately 1 minute
why do we slowly return to normal in counterstrain?
a rapid return could reactivate spindle cell activity
where can tender points be found
where motor nerve pierces investing fascia and enters the muscle
tendons, ligaments, fascia, muscle bellies
where do you document counterstrain
in objective
usually abbreviated
