Hand Grip Strength Test

A hand dynamometer is a device used to measure grip strength, providing an objective assessment of hand and forearm muscle function. The hand grip strength measurement test evaluates the isometric strength of the muscles in the hand and forearm, which is crucial for identifying strength levels in sports that rely heavily on the hands and arms, as well as in physical therapy to pinpoint muscular weaknesses.

Before performing the test, it is essential to ensure that the dynamometer is well-calibrated and to collect user data such as sex, age, weight, height, and dominant hand, as modern dynamometers often incorporate these variables into their results.

During the test, the individual squeezes the device, and the dynamometer measures and displays the grip strength in units of force. This measurement aids healthcare professionals in developing personalized treatment plans, monitoring patient recovery, and comparing an individual's strength to normative data. Overall, a hand dynamometer is a valuable tool for assessing muscular strength and functional performance.

Measuring hand strength


  • Ensure the dynamometer is properly calibrated.
  • Collect the individual's data, including sex, age, weight, height, and dominant hand, as these factors can influence the results.


  • Have the individual sit in a comfortable chair with their back straight and feet flat on the floor.
  • The arm being tested should be at a right angle, with the elbow by the side of the body, not touching the torso.
  • The forearm should be in a neutral position, thumb facing up.

Setting the Dynamometer

  • Adjust the handle of the dynamometer to fit the individual's hand size. The handle should rest comfortably on the middle of the four fingers, with the thumb wrapped around the other side.
  • Instruct the individual to hold the dynamometer away from any surfaces to avoid interference.

Conducting the Test

  • Ask the individual to squeeze the dynamometer as hard as possible for about 3-5 seconds.
  • Ensure they maintain a consistent effort and do not use other parts of their body to generate force.
  • Encourage them to give maximum effort but avoid jerky or sudden movements.

Recording the Results

  • Note the reading displayed on the dynamometer.
  • Repeat the test two more times, allowing a short rest period (about 30 seconds to 1 minute) between trials to prevent muscle fatigue.
  • Record the highest value of the three attempts as the final grip strength measurement.

Comparison and Analysis

  • Compare the results to normative data based on the individual's sex, age, and other relevant factors to assess their grip strength relative to standard benchmarks.
  • Use the data to inform treatment plans, track progress, or identify potential issues.


The highest result should be recorded and compared to a guide for adults (these tables may vary depending the dynamometer brand or study)
