9/27 - RC Nonop Therex Considerations Flashcards
(45 cards)
what are the goals of therex when treating RC (5)
- joint compression
- dynamic ligament tension
- NM control
- ST control
- mobility»_space; stability»_space; controlled mobility»_space; skill
what is an important concept to consider when treating pts when RCs
mobility
> stability
» controlled mobility
»> skill
what other ms should be considered when prescribing therex for RC
delt, upper trap, pec minor
think ab exercises that would be good for RC without activating those ms
how can you prescribe therex for RC without overwhelming the pt
couple exercises that will minimize other ms group activation
exercises that target multiple ms groups
empty vs full can motion
empty can - thumb down, elevation, IR
full can - thumb up, depression, ER
which can is more irritating for impingement
empty
- IR - greater tub isn’t clearing acromion
what path is sidelying ER therex great for
posterior RC
what are the 2 ways that ER therex can be set up? what are the pros/cons of each?
- arm at side - stable environment
- arm up - challenging
- scap musculature need to work harder to stabilize
- more functional
what is a general rule for how to make stability exercises more difficult
as gets further away from body
what ms are specifically activated in sidelying ER
infra & teres minor (aka posterior cuff)
how does adding a towel roll to sidelying ER change the exercise
inc infra activity
- keeps motion in scap plane
improves the form by keeping arm at side
how is ER at 90deg ABD more functional than when arm is at side
more functional for overhead athletes/workers
when should ER at 90deg ABD be avoided and/or why with caution
avoid in early stage of rehab
caution - inc strain on capsule in 90-90 position
where & how should force be applied for manual resistance in ER
at medial border of inferior scap angle and at arm
work to get concentric and eccentric contractions thru whole motion
what is a characteristic of subscap ms fibers that should be considered for therex
upper and lower fibers act independently
what therex motions had the greates subscap activity
pushup plus
diagonal exercises (ie tennis forehand)
what position is not ideal for optimal subscap activation and why
IR at 0deg
d/t co-contraction of:
- ant delt
- pec major
- lats
what is a consideration of upper vs middle vs lower trap when determining therex
upper almost always strong
- will compensate for middle & lower trap weakness
want to prevent upper trap involvement when prescribing middle and lower trap exercises
optimal exercises for upper, middle, and lower traps
upper - unilateral shrug
middle - prone elevation & H - ext (“T”)
lower - prone elevation (“Y”)
how do T vs Y motions change the activation of middle vs lower traps
changes alignment of fibers
- T = middle
- Y = lower
what is a consideration of ms activation for unilateral scap retractions
see more upper trap than lower trap activation
what exercises minimize upper trap while activating lower trap
SL flex
SL ER
prone H-ABD in ER
what exercises minimize upper trap while activating middle trap
SL flex
SL ER
prone ext
what is the difference in sidelying flex compared to sitting or standing flex
sitting or standing, prime position for UT to work
sidelying limits mechanical advantage to use UT
