Abstract

BACKGROUND: With the major impact of post-stroke upper limb motor deficits despite rehabilitation, there is a need to improve manual dexterity assessment. In this study, we aimed to assess the validity of the MDT-AV, a gross manual dexterity assessment developed in augmented virtuality, by comparing it with the gold standard assessment for manual dexterity (BBT) and an immersive virtual reality assessment of manual dexterity (BBT-VR). METHODS: The manual dexterity of 30 healthy adults was assessed using the conventional BBT, the BBT-VR and the MDT-AV. They were performed with a random order and three times for each hand. Spearman Correlation Coefficients were calculated by comparing the score of the MDT-AV to the other two tests. We also analyzed the usability of the MDT-AV and the test-retest reliability of all tests. RESULTS: Strong correlations were found between BBT and MDT-AV for the dominant (r=0.651; p<0.001) and non-dominant hand (r=0.598; p<0.001), and also between BBT-VR and MDT-AV for the dominant (r=0.535; p=0.003) and non-dominant hand (r=0.552; p=0.002). The test-retest reliability was found to be good to excellent for the 3 assessments. The usability of the MDT-AV was rated as excellent. CONCLUSION: The MDT-AV is a valid and reliable tool for assessing global manual dexterity. The excellent usability of this test suggests that the MDT-AV is promising and should be further studied in a larger population of healthy participants and stroke survivors.
