“…The scientific literature related to these issues suggests that the Biometrics E-LINK dynamometer and pinchmeter are used around the world, both for the assessment of daily activities, muscle activity, functional status, and to measure the effects of rehabilitation or surgical interventions [ 39 – 49 ], both in healthy participants [ 39 ] and patients with various upper limb problems associated with: hand prosthesis [ 40 ], spinal cord injury [ 41 ], stroke [ 42 ], distal radius fractures [ 43 ], osteoarthritis [ 44 ] multiple sclerosis [ 45 ], chronic lower back pain [ 46 ], tennis elbow [ 47 ] carpal tunnel release [ 48 ], heart disease and pulmonary hypertension [ 49 ]. However, despite such multi-faceted use of this device, there are few reports in the field of inter- and intra-rater reliability in the field of hand grip and pinch strength measurement using the Biometrics E-link [ 37 , 50 ].…”

The aim of the study was to assess the external and internal compatibility of the Biometrics E-LINK EP9 evaluation system device in the area of hand grip and pinch strength in the Polish population. The testing of hand grip and pinch strength was carried out among 122 healthy students. Two examiners performed hand grip and pinch strength measurements with a Biometrics E-LINK EP9 evaluation system device. Measurements were made for the right and left hands. The same people were tested again two weeks later, under the same conditions. The scores of one rater on the first and second tests were compared for reproducibility, and the scores of the two raters were compared to assess the reliability of the instrument. The measurements were found to be highly consistent both between the investigators and between the tests in the hand grip dynamometer test. The findings show high values of the Pearson’s correlation coefficient equal or close to 1, as well as the interclass correlation coefficient (ICC) >0.9. Analysis of pinch strength measurements performed using the pinchmeter also found high values of the Pearson’s correlation coefficient close to 1, as well as the interclass correlation coefficient >0.9; this reflects high agreement between the measurements performed by two investigators as well as assessments performed by one investigator at time intervals. These findings were confirmed by analyses performed using Bland-Altman plots. The measurements made with the Biometrics E-link EP9 evaluation system show high internal and external consistency in hand grip and pinch strength assessment. Biometrics E-link EP9 can be recommended for daily clinical practice.
