Muscle Performance Examination and Intervention Principles Flashcards

1
Q

Isotonic Testing

A

Joint movement occurs against a fixed or variable load

includes (concentric) and (eccentric)

Q

Repetition Maximum

A

Maximal weight a person can lift in perfect form

Requires you to determine failure or inability to complete next rep

Q

Isokinetic Testing

A

Joint movement that occurs at a fixed speed

Accommodating resistance

Load is matched

quantifies fatigue or amount or rate of force decline

quantify rate of force development

Q

Isometric Testing

A

No apparent motion at joint (static testing)
external load equals the force produced by the muscle
Manual techniques (MMT)
Instrumented techniques

16
Q

Objective

A

ability of patient to complete full ROM or to hold position
ability to move against gravity or inability to move at all

17
Q

Break test

A

PT applies resistance until muscle contraction overcome by patient
More force than make test
“hold this position, dont move”

18
Q

Make test

A

Set force level and ask patient to match it
Force lower than break test
commonly used with HHD

19
Q

Intrarater

A

reliability is good

20
Q

Interrater

A

reliability is fair/good

21
Q

Grades above good (4)

A

Not strong with other strength measures

22
Q

Grades below good (4)

A

strong relationships with other strength measures

23
Q

MMT reliability depends on

A

muscle tested
experience/ education of tester
patients
studies

24
Q

Errors affecting reliability

A

submaximal contractions
substitutions
report of wrong side

25
Q

Strengths of MMT

A

always available
inexpensive
useful for individual muscles

26
Q

Weakness of MMT

A

imprecise
reliability/validity issues
ceiling effects
