ABSTRACT
BACKGROUND:
The Nine-Hole Peg Test (9HPT) is the golden standard to measure manual dexterity in people with multiple sclerosis (MS). However, administration requires trained personnel and dedicated time during a clinical visit.OBJECTIVES:
The objective of this study is to validate a smartphone-based test for remote manual dexterity assessment, the icompanion Finger Dexterity Test (FDT), to be included into the icompanion application.METHODS:
A total of 65 MS and 81 healthy subjects were tested, and 20 healthy subjects were retested 2 weeks later.RESULTS:
The FDT significantly correlated with the 9HPT (dominant ρ = 0.62, p < 0.001; non-dominant ρ = 0.52, p < 0.001). MS subjects had significantly higher FDT scores than healthy subjects (dominant p = 0.015; non-dominant p = 0.013), which was not the case for the 9HPT. A significant correlation with age (dominant ρ = 0.46, p < 0.001; non-dominant ρ = 0.40, p = 0.002), Expanded Disability Status Scale (EDSS, dominant ρ = 0.36, p = 0.005; non-dominant ρ = 0.31, p = 0.024), and disease duration for the non-dominant hand (ρ = 0.31, p = 0.016) was observed. There was a good test-retest reliability in healthy subjects (dominant r = 0.69, p = 0.001; non-dominant r = 0.87, p < 0.001).CONCLUSIONS:
The icompanion FDT shows a moderate-to-good concurrent validity and test-retest reliability, differentiates between the MS subjects and healthy controls, and correlates with clinical parameters. This test can be implemented into routine MS care for remote follow-up of manual dexterity.Palabras clave
