This document provides guidance on performing manual muscle testing of the upper extremities. It describes testing individual muscles and muscle groups, assessing range of motion, and classifying the amount of resistance a muscle can provide on a scale of 0 to 5. Key points include stabilizing the proximal joint while palpating the muscle belly and applying resistance distally, always explaining the test to the client, and stabilizing safely without putting pressure on joints. Grades 0 to 3 test in a gravity eliminated plane while grades 3 to 5 test against gravity. The document also includes a table with positioning and resistance guidelines for specific upper extremity muscles.

Upper Extremity Manual Muscle Testing

Tests individual muscles and muscle groups (motions)


Looks at Joint AROM (Complete, Partial, None?)
Looks at amount of Resistance (Maximal, Moderate, Slight?)
Can do MMT against gravity or on a gravity eliminated plane
depending on ct.
Always look at AROM before assessing STRENGTH!

***Gravity eliminated means on a horizontal plane

When Administering the Break Test (MMT)


1. Ask Client - Can you move your arm up toward the ceiling like this?
(Observe how they do)
2. Then say - Okay, please do the same movement again. Now, position
arm full ROM. (STABILIZE PROXIMALLY & PALPATE)
3. Then say Good, now, hold your arm in this position & dont let me
push it down, up, in or out depending on what muscle or muscle group
you are testing.
4. Apply resistance distally In direction movement came from (LIGHT
AT FIRST & INCREASE TO MAX OVER 2-3 SECONDS)

Things to remember:
Always explain to client what you are going to do
Stay off of clients joints
Stabilize proximally, Palpate muscle group & Apply resistance distally
