Final answer:
A goniometer is not used to measure muscle strength. Muscle strength can be measured using techniques such as manual muscle testing and dynamometry.
Step-by-step explanation:
A goniometer is not an instrument used to measure muscle strength. It is actually a tool used to measure the range of motion in a joint.
Muscle strength can be measured using different techniques such as manual muscle testing, dynamometry, or hand-held dynamometers. For example, a dynamometer is a device that measures the force exerted by a muscle during contraction. It can be used to assess muscle strength in various body parts.
