Lafayette Instrument Hand-Held Dynamometer is a valid and proven assessment tool used for objectively quantifying muscle strength. The Lafayette HHD (formerly known as the Manual Muscle Tester) has a high inter/intrarater reliability and is the ideal instrument for documenting medical necessity or tracking the progress during a rehabilitation or a strength training program.


Manual Muscle Testing Device Measures

  • Peak force
  • Time to reach peak force
  • Total test time
  • Time within selectable ranges
  • Average force
  • Real-time force
  • End force
  • Average force from peak to end
  • Percentage decrease from peak force to end force


More Information

  • When performing repeated tests, inconsistent placement of the MMT will adversely affect scores.
  • Extreme temperature, especially heat, may affect the values obtained.
  • The MMT cannot tolerate the stress of being used as a floor scale.
  • Care should be taken not to drop the MMT, as it may affect the calibration.
  • Exceeding the force limit (300lbs/136kg/1335N) may permanently damage and/or invalidate the calibration of the MMT.
  • Upon initial receipt of MMT, charge for 2 hours.
  • Stirrup should be rotated clockwise on and off to reduce friction on O-ring.
