Our balance changes. Stēla helps you understand the system that you rely on every day. Eight short tests, about five minutes with your phone, and you have a reading of what your balance is and which way it's moving. WHAT YOU GET A single number that reflects how you perform across the session, plus the individual test scores that feed it. Each test isolates a different sensory system, so the comparison between your scores reveal which system is carrying load and which is drifting. Tap "Begin" on Home. Follow the 8 tests. Phone placement: hold the phone steady with two hands, arms comfortably at sides, screen facing up, during each test. On completion, view results for the session scores. See updated trend and history. THE 8-TESTS • Standing, eyes open • Standing, eyes closed • Narrow stance, eyes closed • Head turn, reactive • Unexpected cue, eyes closed • Forward head posture • Dual task, arithmetic • Dual task, verbal fluency Vision, inner ear (vestibular), body position sensing (proprioception), and reactive control each get their own window. Dual tasks add cognitive load, because real balance in the world rarely happens in silence. TRACKING OVER TIME One is a starting point. Over time you have a direction. WHAT STĒLA IS AND IS NOT Stēla is a measurement. It produces quantitative postural sway data intended for self-observation, clinical supplementation, and longitudinal tracking. It is not a diagnostic device. It does not screen for, diagnose, or treat any medical condition. Clinical judgment remains with the supervising clinician. If you have a known fall history, vestibular disorder, or neurological condition, consult a clinician before using Stēla unsupervised. THE SCIENCE Stēla uses peer-reviewed measurement methods adapted for phone-based sensors. Test-retest reliability, scoring methodology are documented on stelabalance.com/science/, with 24 references.
