Both hands were tested in within-day and between-day sessions, with vision and without vision. Measures of maximal tactile pressures and forces were measured for the complete grasp duration (8s) and for the plateau phase (5s). Measures of maximal tactile pressures and forces were reported using the highest value among three repeat trials, the mean of two repeat trials, and the mean of three repeat trials. Reliability was determined using changes in mean, coefficients of variation and intraclass correlation coefficients (ICCs). Pearson correlation coefficients were used to evaluate concurrent validity. Results: Changes in mean were very good, coefficients of variation were good to acceptable and ICCs were very good to good for maximal tactile pressures using the highest value among three repeat trials and the mean of three repeat trials for the complete grasp duration (8s) and for the plateau phase (5s) in the dominant hand with and without vision and in the non-dominant hand without vision for within-day and between-day sessions. Maximal tactile pressures had moderate to large correlations with grip strength. Conclusion: The TactArray device demonstrates satisfactory reliability for maximal tactile pressures during a sustained grasp for within-day and between-day testing sessions in both hands. Validity was satisfactory with grip strength in both hands.]]> Fri 11 Nov 2022 18:58:47 AEDT ]]>
