Jamar Hydraulic Hand Dynamometer Overview

Jamar Hydraulic Hand Dynamometer is designed for quick and accurate evaluations of isometric grip force (hand grip strength). This hydraulic hand grip dynamometer is lightweight, portable, and can provide readings for up to 200 pounds or 90 kilograms. This dual-scale dynamometer uses sturdy components and features an adjustable handle with five different settings to accommodate various hand sizes. Jamar Hydraulic Hand Dynamometer product pairs nicely with an Xtensor Hand Strengthener.

Dual-Scale Readout

Jamar Grip Dynamometer displays grip force in pounds as well as kilograms, allowing readouts of up to 200 pounds or 90 kilograms.

Peak-Hold Needle

Jamar Hydraulic Hand Dynamometer uses a peak-hold needle that automatically retains the highest reading until it is reset, making it perfect for quick recording.

Adjustable Handle

Jamar Hand Dynamometer accommodates various hand sizes with five different grip positions, ranging from 1 3/8 inches to 3 3/8 inches.

Use and Care Instructions

  1. Set the adjustable handle to the desired spacing. If the handle is not replaced in the correct position, the readings will not be accurate.
  2. Rotate the red peak-hold needle counter-clockwise to zero.
  3. Let the patient comfortably arrange the instrument in his or her hand. Have the patient squeeze with their maximum strength. The peak-hold needle will automatically record the highest force exerted.
  4. Record the reading and reset the peak-hold needle to zero for future uses.
  5. Please note that temperature extremes during shipping may cause the gauge needle to rest slightly away from zero. If this is the case, follow the steps below to reposition the gauge needle.
  6. Unscrew the crystal and locate the center screw that holds the gauge needle.
  7. Carefully hold the needle between the thumb and forefinger.
  8. Using a screwdriver, turn the screw clockwise to move the needle lower or counter-clockwise to move the needle higher.
  9. Check the needle to make sure it is not bent before replacing the crystal.
  10. Be sure to keep the dynamometer in a room temperature area when not being used.

Hand Dynamometer Indications

  • Uniform measurement of handgrip strength

Frequently Asked Questions (FAQ)

Q: How do dynamometers work?
A: The patient squeezes the handheld device with all of their strength, usually three times for each hand, and an average score is calculated using the measurements from both hands. Dynamometers come in various forms. The Jamar Dynamometer is a hydraulic (operated by a liquid moving in a confined space under pressure) device.

Q: What is the normal grip strength?
A: Men between 20 and 30 years of age tend to have the greatest strength, while women over 75 years of age have the lowest. In people aged 20 to 29 years old, the average grip strength is 46 kilograms (101 pounds) for men and 29 kilograms (64 pounds) for women.

Q: How is grip strength measured?
A: Hand grip strength can be quantified by measuring the amount of static force that the hand can squeeze around a dynamometer. This force is most often measured in kilograms and pounds, but can also be measured in millimeters of mercury (mmHg) and in Newtons.
