SWAY Mobile Application Assessments in Healthy Adults

SWAY Medical, Inc. (SWAY) has developed a mobile application that assesses balance, functional performance, and cognitive function. Clinical reliability, validity, and normative data have been studied extensively in individuals aged 5 to 20. The accuracy of the SWAY Mobile Application in assessing conditions associated with head injury has also been well established. The objectives of this study are to examine the reliability and validity, and establish normative data, for SWAY balance, functional, and cognitive assessments in healthy adults aged 21-90. The SWAY smartphone app will be used to record balance, simple reaction time, impulse control, inspection time, working memory, reverse number counting, flanker task, modified Stroop, and 30 second chair stand test results. The following tests will be administered to participants: Test of Premorbid Functioning, WAIS-IV Logical Memory, WMS-IV Older Adult Logical Memory, Animal Fluency, Boston Naming Test, D-KEFS Color Word Interference Test, WMS-IV Symbol Span, WAIS-IV Coding, Auditory Consonant Trigrams, Verbal Fluency (FAS), and Flanker Inhibitory Control and Attention Test.

Exclusion Criteria:Uncorrected visual or hearing impairment that interferes with testingAlcohol or drug intoxicationSevere, untreated psychiatric illness (e.g., schizophrenia, bipolar disorder, depression)Cognitive impairment (e.g. dementia)Motor impairments that may interfere with testingIndividuals who have a self-reported history of falling or are believed to be at-risk of falling may be excluded from the balance testing portion of the study but will remain eligible to participate in the functional and cognitive assessment portions of the study. Participants over the age of 50 will complete a short fall risk screening assessment.Individuals who have a musculoskeletal injury affecting functional movement and balance may be excluded from the balance testing portion of the study but will remain eligible to participate in the cognitive assessment portions of the study.Volunteers may also be excluded from portions of this study if they do not have the necessary technology to maintain a Zoom connection required for remotely administered follow-up assessments, and a smart-device capable of downloading and operating the SWAY application.
