Investigation of Study Procedures to Estimate Sensitivity and Reliability of a Virtual Physical Assessment Developed...

Area of Science:

• Neurology
• Rehabilitation Medicine
• Digital Health

Background:

• Remote concussion assessment feasibility is underexplored.
• Limited data exists on psychometric properties of remote physical assessments.

Purpose of the Study:

• Assess feasibility and acceptability of remote concussion evaluations.
• Determine recruitment capability for future studies.
• Estimate preliminary sensitivity and reliability of remote assessments.

Main Methods:

• 20 individuals with acquired brain injury completed in-person and remote assessments.
• Assessments included finger-to-nose, balance, and Vestibular/Ocular Motor Screening (VOMS).
• Clinicians reviewed remote assessment recordings for interrater and intrarater reliability.

Main Results:

• Recruitment rate was 61%; 20 participants completed the study.
• Remote assessments averaged 13 minutes; both methods were deemed acceptable.
• Preliminary sensitivity ranged from 0.0 to 1.0; reliability ranged from 0.38 to 1.0.

Conclusions:

• Remote concussion assessment procedures are feasible and acceptable.
• Some measures show promising psychometric properties.
• A larger study is needed to confirm findings due to small sample size.
