Quiz 4: 1 Flashcards
What MVC should you start with for an exercise program?
60-80%
What is the scale used to determine intensity for a pt?
OMNI resistance scale
What number do you want the pt to be on the OMNI scale?
start at 6
If a muscle does not function in a(n) _____ pattern, it cannot function in a functional pattern
isolated
Should we test motions or individual muscles before training?
individual muscles
Should we start with gross motor exercises or isolated muscle exercises in the absence of isolated muscle weakness or reduced function in MMT?
gross motor
How do we stress shield a healing muscle?
- gross motor
- multi-muscle and multi-joint exercises
How long should isometric exercises be held for?
6 seconds
How should a single rep of isometric exercise be graded?
- 2 second gradual increase
- 6 second hold
- 2 second gradual decrease
How much physiologic overflow do you get with isometric exercise/strength training?
20%
10˚ in each direction
Which part of the motion should you focus on with isometric exercises?
end range
List 5 reasons why to introduce isometrics early on in rehab
- creates muscle activation
- prevents atrophy
- increases strength
- decreases pain
- physiological overflow through ROM
How long does it take for subjective complaints of pain (DOMS) to subside after a bout of eccentric exerciese?
7-10 days
Where does microtrauma occur (components of muscle) with DOMS?
- SEC
- PEC
What substance is released to create the noxious stimulus of DOMS?
hydroxyproline
In an untrained individual, how many sets of exercise do you do for UE exercise?
1
In an untrained individual, how many reps of exercise do you do for UE exercise?
10
In an untrained individual, how long do you wait to increase the number of sets?
1 month`
In a trained individual, how many sets do you do?
multiple, but typically 3
Why should you do 10 reps in each set?
best results for endurance, strength, and power
If you only do 5 reps per set, what are you working on?
strength only
If you do 15 reps per set, what are you working on?
endurance only
What format should you use in your training method?
superset
agonist/antagonist
4 reasons to use superset format
- saves time
- provides muscle recovery time
- efficiency in developing a program
- works on muscle balance
What frequency should you use in your training protocol?
3x/wk
every other day
How much/quickly should you progress a pt?
2-10% increase per week of total volume of work
*done by increasing reps, sets, or weight
Relative rest intervals for isometrics
~ 1 min
Relative rest intervals for isotonics
30-60s
Relative rest intervals for isokinetics
2-4 mins
Frequency for strength training
- 3-4x/wk
- every other day
- need to rest to gain strength
How long does it take for morphological changes to occur?
over 4 weeks
What changes occur within the muscle in the first 4 weeks?
neuromuscular
The majority of patellar dislocations occur in which age range?
10-17 y.o.
What is the primary direction of patellar dislocation?
lateral
What keeps the patella from dislocating?
- retained by medial retinacular structures
- esp the MPFL
What % of pts continue to have limitations with strenuous activity 6 months post-injury (patellar dislocation)
58%
What is the Elftman Proposal?
optimal force production of different modes of contraction is arranged in a predictable hierarchy
What is the hierarchy of modes of force production with the Elftman proposal?
eccentrics » isometrics » concentrics
How much of a difference in force production is there between each type of contraction?
10-40% more
