Physical function decline due to aging or disease can be assessed with quantitative motion analysis, but this currently requires expensive laboratory equipment. We introduce a self-guided quantitative motion analysis of the widely used five-repetition sit-to-stand test using a smartphone. Across 35 US states, 405 participants recorded a video performing the test in their homes. We found that the quantitative movement parameters extracted from the smartphone videos were related to a diagnosis of osteoarthritis, physical and mental health, body mass index, age, and ethnicity and race. Our findings demonstrate that at-home movement analysis goes beyond established clinical metrics to provide objective and inexpensive digital outcome metrics for nationwide studies.

“…PROMIS Global Health (PROMIS-GH) is the shortest PROMIS short-form that measures five generic domains of health (physical functioning, pain, fatigue, emotional distress, social health) using 10 global health items [ 10 ]. Its validity, reliability and responsiveness have been confirmed in several populations, including patients with stroke [ 11 ], orthopaedic conditions [ 12 – 16 ], amyloidosis [ 17 ], inflammatory bowel diseases [ 18 ], pregnant women [ 19 ] and older adults [ 20 ]. The international use of PROMIS-GH has also been expanding outside the US, including studies from the UK [ 21 ], Germany [ 22 ] and the Netherlands [ 23 ].…”

Objectives Patient-Reported Outcomes Measurement Information System–Global Health (PROMIS-GH) is a widely used generic measure of health status. This study aimed to (1) assess the psychometric properties of the Hungarian PROMIS-GH and to (2) develop general population reference values in Hungary. Methods An online cross-sectional survey was conducted among the Hungarian adult general population (n = 1700). Respondents completed the PROMIS-GH v1.2. Unidimensionality (confirmatory factor analysis and bifactor model), local independence, monotonicity (Mokken scaling), graded response model fit, item characteristic curves and measurement invariance were examined. Spearman’s correlations were used to analyse convergent validity of PROMIS-GH subscales with SF-36v1 composites and subscales. Age- and gender-weighted T-scores were computed for the Global Physical Health (GPH) and Global Mental Health (GMH) subscales using the US item calibrations. Results The item response theory assumptions of unidimensionality, local independence and monotonicity were met for both subscales. The graded response model showed acceptable fit indices for both subscales. No differential item functioning was detected for any sociodemographic characteristics. GMH T-scores showed a strong correlation with SF-36 mental health composite score (rs = 0.71) and GPH T-scores with SF-36 physical health composite score (rs = 0.83). Mean GPH and GMH T-scores of females were lower (47.8 and 46.4) compared to males (50.5 and 49.3) (p < 0.001), and both mean GPH and GMH T-scores decreased with age, suggesting worse health status (p < 0.05). Conclusion This study established the validity and developed general population reference values for the PROMIS-GH in Hungary. Population reference values facilitate the interpretation of patients’ scores and allow inter-country comparisons.
