How to Use This Calculator
  1. Enter Grip Strength, Patient Age, and Female.
  2. Set Hand Tested.
  3. Review Percentile Rank (%ile) and Classification ((1=Weak, 2=Below Avg, 3=Average, 4=Above Avg, 5=Strong)).
  4. Use Dominant/Non-Dominant Ratio to inform your decision.

What each input means

Grip Strength
Measured grip strength in kilograms using a dynamometer (best of 3 trials).
Patient Age
Age of the patient in years for normative comparison.
Female
0 = Male, 1 = Female. Used for sex-specific normative data.
Hand Tested
1 = Dominant hand, 2 = Non-dominant hand.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Grip Strength = 35, Patient Age = 50, Female = 0, Hand Tested = 1 = 4 input(s) provided
  2. Calculate Percentile Rank
    Percentile Rank
    18 = 18
  3. Calculate Classification
    Classification
    2 = 2
  4. Calculate Dominant/Non-Dominant Ratio
    Dominant/Non-Dominant Ratio
    1.11 = 1.11
