Muscle strength measurements using handheld dynamometry (HHD) increase with faster angular velocities. The make technique may offer more reliable strength assessments compared to the break technique.

Area of Science:

  • Neurology
  • Rehabilitation Medicine
  • Biomechanics

Background:

  • Handheld dynamometry (HHD) is widely used to assess muscle strength.
  • Previous studies show variability in strength measurements using different HHD techniques (make vs. break).
  • The influence of angular velocity on HHD measurements is not fully understood.

Purpose of the Study:

  • To investigate if muscle strength, measured by break-technique HHD, is dependent on angular velocity.
  • To compare the reliability of HHD at different angular velocities.

Main Methods:

  • A repeated-measures study involving 20 individuals with tetraplegia.
  • Participants performed HHD using make-technique (isometric) and break-technique (eccentric) at three velocities (15, 33, 55 degrees/s).

  • Elbow movement and strength were recorded using an electrogoniometer and HHD.

    • Main Results:

    • Break-technique HHD yielded 16%, 30%, and 51% greater strength measurements at 15, 33, and 55 degrees/s, respectively, compared to the make technique (P < .006).
    • Intrarater reliability (intraclass correlation coefficient) was ≥0.89 for all techniques.
    • Higher angular velocities resulted in significantly greater recorded strength.

    Conclusions:

    • Muscle strength measurements obtained via HHD are influenced by angular velocity.
    • Angular velocity variations may account for discrepancies in reported strength values between break and make techniques.
    • The make technique is potentially more reliable for serial strength measurements due to lower variability.
