MMT Testing Procedures 3

Question 1

In the Kendall MMT system, the percentage score assigned to a normal (Grade 5) muscle is:

Accepted Answer

100%

Answer

In Kendall's percentage-based system, Grade 5 Normal equals 100%, representing full strength against maximum resistance.

Question 2

A clinician asks the patient to 'hold, don't let me move you.' This instruction indicates the examiner is performing:

Accepted Answer

An isometric break test

Answer

The instruction to 'hold' while the examiner attempts to move the segment is the classic setup for an isometric break test used in standard MMT.

Question 3

Which factor does NOT directly affect the reliability of manual muscle test results?

Accepted Answer

Time of day the test is performed

Answer

While minor fatigue variation exists throughout the day, time of day is not a recognized primary factor affecting MMT reliability, unlike examiner skill, patient effort, and standardized positioning.

Question 4

When testing hip abductor strength, the patient is typically positioned in:

Accepted Answer

Sidelying with test limb uppermost

Answer

Hip abductors are tested in sidelying with the test limb on top, allowing the limb to move laterally against gravity through the full ROM.

Question 5

If a patient demonstrates a Trendelenburg sign during single-leg stance, which hip muscle group is most likely testing below Grade 3?

Accepted Answer

Hip abductors

Answer

A positive Trendelenburg sign indicates weakness of the stance-side hip abductors, which normally stabilize the pelvis during single-leg support.
