Method & Evidence

AimTo assess the reliability and clinical applicability of the Enhanced Paper Grip Test (EPGT) for measuring lower limb strength.
MethodTest-retest and inter-rater reliability study, with clinical applicability assessment.
ProcedureTwo experts administered the EPGT to healthy adults, measuring hallux grip force using a dynamometer. The same standardized protocol was used for all participants. Clinical applicability was assessed in community-dwelling adults.
Sample45 participants (20 for reliability, 15 for clinical applicability)
ContextPhysical therapy and rehabilitation settings, assessment of lower limb strength.

Variables

IVTest administration (e.g., by different examiners, at different times).
DVHallux grip force (measured in Newtons).
CVStandardized protocol for EPGT administration, type of dynamometer used, participant demographics (e.g., healthy adults).
04

Strengths & Limitations

Strengths

  • +Demonstrated good to excellent reliability metrics (ICC values).
  • +Investigated both test-retest and inter-rater reliability.

Limitations

The study was conducted on a specific group of adults; results might differ for other age groups or individuals with foot conditions.

Reliability & validity

The study focused on reliability (test-retest and inter-rater) by examining the consistency of measurements. Validity (whether it measures what it intends to measure) is implied by its clinical applicability but not directly tested in this paper.

Think critically

How might the EPGT be adapted or modified to assess different aspects of lower limb function, such as endurance or dynamic strength, for use in a design project?

05

Design Principles

"Quantify human physical performance with validated and reliable testing methods to inform design decisions."

Understanding and quantifying subtle variations in human physical capabilities is crucial for designing assistive devices, rehabilitation tools, and even everyday products. This research offers a validated method to assess a specific aspect of human motor function, enabling more precise design interventions.
