Abstract

BACKGROUND The Box and Block Test (BBT) is one of the assessment tools used by therapists to evaluate the impact of motor disorders on patient’s activity. The objective of our study is to validate a virtual version of the BBT (BBT-VR) in a population of healthy subjects and in patients with stroke. METHODS 23 healthy adult subjects and 21 patients with stroke will be evaluated using the conventional BBT and the BBT developed in virtual reality. The order of the experiment will be randomized. The subjects had to do 3 trials of each tests and will answer Stroke Usability Scale questionnaire (SUS). Pearson Correlation Coefficients was computed between the BTT and the BBT-VR score. The test-retest reliability, SUS score, and the effect of age, sexe, laterality, affinity for technology, dexterity, and stroke stage was determined. RESULTS The number of blocks displaced in the BBT-VR and in the classical BBT were strongly correlated in healthy control subjects (r = 0.67; p<0.001) and in adults with stroke (r = 0.83; p<0.001). A strong correlation was shown in the test-retest reliability in VR in patients with stroke for both paretic (ICC = 0.87; p<0.001) and less affected hand (ICC = 0.8; p<0.001). CONCLUSION The results showed a strong correlation between BBT-VR and BBT whish demonstrates an excellent reliability and validity of this tool for the assessment of the global manual dexterity of UL patients with stroke.
