BalanSens™

Objective balance and postural sway assessment with wearable sensors.

BalanSens is a portable, FDA-listed wearable system for objective assessment of balance and postural sway. Two body-worn inertial sensors estimate center-of-mass motion and quantify sway during standard balance tasks, without a force plate.

Balance assessment without a force plate

Force plates can quantify postural control, but dedicated equipment can limit where assessments take place. BalanSens brings balance assessment to the study setting with two lightweight sensors: it estimates center-of-mass sway from ankle and hip motion to support standardized testing and repeated measurements across clinical sites and remote study visits.

What BalanSens measures

BalanSens estimates center-of-mass sway from ankle and hip motion to quantify postural control during standard balance tasks.

  • Sway index

    A summary measure of postural sway during the selected balance task.

  • Sway area

    Estimated area covered by center-of-mass sway during the balance task.

  • Sway velocity

    Estimated speed of center-of-mass motion during the balance task.

  • Directional sway

    Estimated side-to-side (ML) and forward-backward (AP) center-of-mass sway.

  • Ankle and hip motion

    Sensor-derived estimates of ankle and hip motion during balance tasks.

  • Postural strategy

    Coordination of ankle and hip motion to characterize postural control strategies.

Designed for objective balance assessment

Portable sensors, standard test protocols, and automated reports make quantitative balance assessment practical across study settings.

  • Two-sensor setup

    Sensors on the shin and lower back capture movement used to estimate center-of-mass sway.

  • Portable sway assessment

    Lightweight and portable, BalanSens delivers objective balance measures without dedicated force-plate hardware.

  • FDA-listed

    An FDA-listed wearable device for objective balance assessment.

  • Studied in clinical research

    Sway measures have been used in published clinical studies, with automated reports available for review.

  • Standard balance tests

    Built-in software modules guide standard balance tests and record performance.

  • Remote-ready

    Works with BioDigit Home for remote balance assessments, with supervision tailored to the study protocol.

BalanSens data across disease cohorts

Balance data from selected patient and healthy-control studies can support digital biomarker research through the BioDigit Database. Research and industry partners can explore cohort-specific data access.

  • Healthy controls

    Balance and sway data from participants without the condition under study, supporting comparisons with patient cohorts.

  • Alzheimer's disease

    Postural sway and balance performance to study functional impairment and differences across test conditions.

  • Charcot-Marie-Tooth disease

    Balance measures to investigate associations with clinical severity in hereditary motor and sensory neuropathy.

  • Corticobasal syndrome

    Balance and postural sway measures to investigate functional impairment in corticobasal syndrome.

  • Huntington disease

    Balance measures in prodromal and manifest cohorts to explore relationships with disease stage and clinical scores.

  • Progressive supranuclear palsy

    Balance and postural sway measures to investigate postural instability and changes in function.

Available measures, participant counts, follow-up duration, and access terms vary by cohort. Data sharing is subject to study consent and applicable agreements.
