SJSU Kin 147 Exam 1 Questions and
Answers 100% Solved | Graded A+
Name different ways to assess muscle function? - ✔✔strength testing
manual muscle testing
dynamometry
electromyography
What is manual muscle testing (MMT)? - ✔✔-a test used to determine the
extent of muscular weakness as a result of disuse, injury, or disease
-can be used to aid diagnoses and plan therapeutic exercises when a
strength deficit exists
concentric contraction - ✔✔muscle shortens as it maintains tension
eccentric contraction - ✔✔muscle lengthens as it maintains tension
isometric contraction - ✔✔Muscle contracts but there is no movement,
muscle stays the same length
What type of contraction is used during MMT? - ✔✔-usually isometric
contraction

, -examinar places patient in optimal position and tries to "break" the patient
by moving them away from their isometric hold
Where should the participant be placed for manual muscle testing? - ✔✔-in
a position of advantage
-muscle is generally placed at optimum muscle length tension relationship
What does an MMT grade of zero signify? - ✔✔none- no visible or
palpablwe contraction
What does an MMT grade of 1 signify? - ✔✔trace- visible or palpable
contraction with no motion
What does an MMT grade of 2 signify? - ✔✔poor- full ROM, gravity
eliminated
What does an MMT grade of 3 signify? - ✔✔fair- full ROM against gravity
What does an MMT grade of 4 signify? - ✔✔good- full ROM against gravity,
moderate resistance
What does an MMT grade of 5 signify? - ✔✔normal- full ROM against
gravity, maximal resistance
T/F: You can modify a patients postion during a physical exam if they are
unable to place themselves in an optimal position by eliminating gravity -
✔✔True
