1

What type of strength testing uses repetition maximum?

isotonic

New cards
2

What type of strength testing uses a dyanmometer?

isokinetic

New cards
3

What type of strength testing uses MMT, dynamometer, and HHD?

isometric

New cards
4

what is isotonic testing

joint movement occurs against a fixed or variable external load

New cards
5

what is isokinetic testing?

joint movement that occurs at a fixed speed, load is matched to maintain

New cards
6

what is isometric testing?

static testing with no apparent joint motion

New cards
7

define MMT

a system of measurement using manually applies resistance to determine strength of a muscle

New cards
8

what is a 5 MMT

Normal- can move through full available ROM against gravity and hold against maximal manual resistance

New cards
9

which MMT test should you start with on a patient

Fair test (full ROM against gravity) then move up or down accordingly

New cards
10

what is a break test?

most commonly used in mmt, where pt applies resistance and tells patient to resist

New cards
11

what variables affect “normal” mmt results

size, age, gender

New cards
12

what should be used as comparison of normal during an mmt?

the good side

New cards
13

what is it important to prevent during MMT?

substitution

New cards
14

what MMT grades have strong relationships w/ other strength measures?

grades below 4

New cards
15

What does an MMT grade of 4 mean?

good- able to move through full ROM against gravity and hold against moderate resistance

New cards
16

What does an MMT grade of 3+ mean?

fair+ : able to move through full ROM against gravity and hold against minimal resistance

New cards
17

What does an MMT grade of 3 mean?

fair : able to move through full ROM against gravity

New cards
18

What does an MMT grade of 3- mean?

fair- : able to move through more than half ROM against gravity

New cards
19

What does an MMT grade of 2+ mean?

poor+ :able to move through less than half RM against gravity

New cards
20

What does an MMT grade of 2 mean?

poor: able to move through full ROM in gravity minimized position

New cards
21

What does an MMT grade of 2- mean?

poor- : able to move through partial ROM gravity minimized

New cards
22

What does an MMT grade of 1 mean?

Trace: no joint motion, gravity minimized position, muscle contraction palpable or observable

New cards
23

What does an MMT grade of 0 mean?

no observable or palpable muscle contraction
