Suggested Grip Strength Testing Protocol

"Based on our findings, we recommend that the following protocol be used in future studies involving frail older adults:

  1. The patient should be comfortably seated with the elbows supported at an angle of 90 degrees to the body.
  2. Three successive tests should be performed using a Jamar hand dynamometer (handle setting adjusted for the comfort preference of the subject) consisting of a grip duration of 3 seconds with a 1-minute rest in between.
  3. Alternating bilateral assessment of hands should be performed with no warm-up tests.
  4. Verbal encouragement should not be provided during the assessment of grip strength.
  5. The maximum measured grip value for each hand should be used for the assessment of frailty."
