Abstract

Sarcopenic obesity, the coexistence of obesity and sarcopenia, significantly impairs mobility, independence, and healthcare. Functional performance tests, including the Timed Up and Go Test (TUG), Five Times Sit-to-Stand Test (5xSTS), and 4-Meter Walk Test (4MWT), are essential for diagnosing and monitoring sarcopenia. This study aimed to evaluate the reliability of tele-assessment methods for functional performance tests compared to face-to-face evaluations in individuals with obesity. A repeated measures observational study was conducted with 82 participants diagnosed with obesity (BMI > 30 kg/m²). All participants completed TUG, 5xSTS, and 4MWT tests both in a clinical setting and at home via video-based tele-assessment. Inter-rater and intra-rater reliability were assessed using intraclass correlation coefficients (ICCs). Inter-rater reliability between face-to-face and tele-assessment formats was good for TUG (ICC = 0.826) and 5xSTS (ICC = 0.880), and moderate for 4MWT (ICC = 0.743). Intra-rater reliability across two tele-assessment sessions was excellent for TUG (ICC = 0.910) and 5xSTS (ICC = 0.902), and good for 4MWT (ICC = 0.858). Tele-assessment is a reliable alternative to face-to-face evaluation for functional performance testing in individuals with obesity. It provides an accessible way to assess mobility and strength, especially for those with limited access to in-person evaluations.
