Objective: The Hand Test System (HTS) is an engineered-sensorized glove that has been originally developed in the neuroscientific field for the evaluation of hand fingers’ speed movement. This pilot-study aimed to evaluate the reproducibility of HTS analysis in rheumatoid arthritis (RA), correlating glove-derived parameters with clinical disease activity indexes, self-reported disability-related questionnaires and hand strength. Methods: Fifty-five RA patients and fifty age and sex matched healthy controls (HCs) performed HTS analysis. The glove recognized the touch speed between the finger tips during standard sequences of movements, providing three quantitative parameters: touch duration (TD), inter-tapping interval (ITI) and movement rate (MR). These variables were correlated with Health Assessment Questionnaire (HAQ), Health Assessment Questionnaire-Disease Index (HAQ-DI), Hand Disability Index (HDI), Hand Grip Strength (HGS), DAS28-CRP, CDAI and SDAI. Results: Intraclass correlation coefficient was 0.93 (CI: 0.92, 0.95). RA patients showed significantly slower TD, ITI and MR than HCs, for all classes of disease activity (P < 0.001). All HTS parameters correlated significantly with HAQ, HAQ-DI, HDI, HGS, DAS28-CRP, SDAI, CDAI (between P < 0.05 and P < 0.001). Of note, also RA patients in clinical remission showed a significantly higher TD compared with HCs (P < 0.001). Conclusion: HTS seems a new safe and fast tool to evaluate rheumatoid hand's functionality, measuring the speed of finger movements. Furthermore, the HTS parameters significantly correlate with quality of life, disease activity, hand strength and perceived hand disability, evaluating also potential hand motor impairment in RA clinical remission.

Abstract

Objective: The Hand Test System (HTS) is an engineered-sensorized glove that has been originally developed in the neuroscientific field for the evaluation of hand fingers’ speed movement. This pilot-study aimed to evaluate the reproducibility of HTS analysis in rheumatoid arthritis (RA), correlating glove-derived parameters with clinical disease activity indexes, self-reported disability-related questionnaires and hand strength. Methods: Fifty-five RA patients and fifty age and sex matched healthy controls (HCs) performed HTS analysis. The glove recognized the touch speed between the finger tips during standard sequences of movements, providing three quantitative parameters: touch duration (TD), inter-tapping interval (ITI) and movement rate (MR). These variables were correlated with Health Assessment Questionnaire (HAQ), Health Assessment Questionnaire-Disease Index (HAQ-DI), Hand Disability Index (HDI), Hand Grip Strength (HGS), DAS28-CRP, CDAI and SDAI. Results: Intraclass correlation coefficient was 0.93 (CI: 0.92, 0.95). RA patients showed significantly slower TD, ITI and MR than HCs, for all classes of disease activity (P < 0.001). All HTS parameters correlated significantly with HAQ, HAQ-DI, HDI, HGS, DAS28-CRP, SDAI, CDAI (between P < 0.05 and P < 0.001). Of note, also RA patients in clinical remission showed a significantly higher TD compared with HCs (P < 0.001). Conclusion: HTS seems a new safe and fast tool to evaluate rheumatoid hand's functionality, measuring the speed of finger movements. Furthermore, the HTS parameters significantly correlate with quality of life, disease activity, hand strength and perceived hand disability, evaluating also potential hand motor impairment in RA clinical remission.
