Validity and Reliability of the InGrip ® Load-Cell Handgrip Dynamometer Compared With the Takei Handgrip Dynamometer in Healthy Adults and Patients With Stroke

Year: 2026

Type: article

Abstract: BACKGROUND: load-cell handgrip dynamometer by comparing its performance with the Takei handgrip dynamometer in measuring handgrip strength (HGS) among healthy adults and patients with stroke. METHODS: dynamometers following a standardized protocol. Correlation, agreement, and test-retest reliability were evaluated using Pearson's correlation coefficient, Bland-Altman plots, intraclass correlation coefficient (ICC), standard error of measurement (SEM), and smallest real difference (SRD). RESULTS: exhibited excellent test-retest reliability, with ICC values exceeding 0.9, SEM below 10%, and SRD under 30% across all groups. CONCLUSION: dynamometer is a valid and reliable instrument for HGS assessment. Further research should explore its applicability across broader clinical and population-based settings.
