Which instrument would you use to measure grip strength in a clinical setting?

• A. Hand dynamometer
• B. Goniometer
• C. Tensiometer
• D. Sphygmomanometer

Answer: (A)

Measuring grip strength requires a device designed to quantify the force produced by the hand, which is a hand dynamometer. It directly captures maximal isometric grip force and is commonly used in clinical rehab to assess hand function, monitor progress, and guide treatment. A goniometer, by contrast, measures joint angles and range of motion, not strength. A tensiometer gauges tension, often related to fluids or fibers, and isn’t used for grip strength. A sphygmomanometer measures blood pressure and has no role in assessing how strongly the hand can squeeze. In practice, the patient sits with the elbow at about 90 degrees, forearm in a neutral position, and wrist in slight extension, then squeezes the dynamometer as hard as possible for a few seconds, with several trials and rest between attempts. The highest value from the trials provides the grip strength measure.
