Agreement between remote and in-person assessments of mobility and balance tests for children with cerebral palsy. A pilot study

Aim: To determine the level of agreement between remote and in-person assessment for the Timed Up and Go test (TUG), the Lateral Step-Up test (LSU), the Five-Times-Sit-To-Stand test (FTSTS), and the Pediatric Balance Scale (PBS) in children with cerebral palsy (CP). Methods: Fifteen children diagnosed with unilateral and bilateral spastic CP and Gross Motor Function Classification System levels I–II underwent these four tests in two distinct environments. These assessments were conducted 24 to 48 hours apart, first in person at the physiotherapy clinic and then remotely at home via the VSee platform. Before the remote assessment, all parents attended a preliminary training session that covered technical proficiency with VSee, the proper setup of home equipment, and essential safety protocols. Results: Children had a median age of 7 (IQR = 6–10) years old. All children successfully finished all four tests in both the home and clinic settings without any reported safety issues. The agreement was good for the time of repetitions in the FTSTS: ICC = 0.884 (95% CI: 0.654 to 0.961; MD = –1.26 seconds, 95% CI: –2.81 to 0.28, p = 0.102), and excellent for the total time of the TUG: ICC = 0.998 (95% CI: 0.990 to 0.999; MD = –0.42 seconds, 95% CI: –0.76 to –0.08, p = 0.017), the total score in the PBS: ICC = 0.998 (95% CI: 0.992 to 0.999; MD = 0.26 units, 95% CI: 0.01 to 0.52, p = 0.041), and the total number of steps in the LSU: ICC = 0.988 (95% CI: 0.965 to 0.996; MD = 0.53 steps, 95% CI: –0.68 to 1.75, p = 0.364). Conclusions: Remote evaluation of the FTSTS, TUG, LSU, and PBS demonstrates good-to-excellent agreement with in-person assessment. However, wide limits of agreement indicated individual variability.
