Is manual muscle testing reliable?
The reliability of individual muscle strength grades ranged from . 80 to . 99, with those in the gravity-eliminated range scoring the highest. Concluded that the MMT was reliable for assessing muscle strength in boys with DMD when consecutive evaluations are performed by the same physical therapist.
What does manual muscle testing measure?
Manual Muscle Testing: A Method of Measuring Extremity Muscle Strength Applied to Critically Ill Patients.
What conditions do you use manual muscle testing for?
MMT is employed by physical therapists to determine the grades of strength in patients with pathological problems and neurologic or physical injuries (strokes, post-polio syndromes, fractures, post-surgical disabilities, etc.).
What are the limitations of manual muscle testing?
The limitations of manual muscle testing arise from the subjective nature of the testing. Because the tester must provide the external resistance, this force may be variable between testers. The variability results in interrater reliability values that are unac- ceptable given other more reliable methods.
What are the grades of manual muscle testing?
Manual Muscle Testing Grading System
| Grading Scale Range: 0 to 5 | ||
|---|---|---|
| 0 | None | No visible or palpable contraction |
| 1 | Trace | Visible or palpable contraction with no motion ( a 1 ) |
| 2 | Poor | Full ROM gravity eliminated |
| 3 | Fair | Full ROM against gravity |
Why is a dynamometer used?
A dynamometer, also known as a “dyno”, is a device that measures force, torque or power. For chassis or engine applications, a dynamometer is designed to create a load to duplicate various speed (RPM) and torque (Nm or lb-ft) requirements. From this data, power (HP or kW) can be calculated.
Can you do muscle testing on yourself?
Muscle testing can either be done for you by another person or you can do it yourself using various methods. Often, when muscle testing is done for you, your arm is used as the indicator muscle. The tester places their hand on a shoulder while you extend your other arm straight out, to the side of your body.
