Know how your device performs between visits
Sentinel captures objective functional outcomes after surgery, neurostimulation, or implant placement using only a patient's smartphone. Movement information is collected passively in real-world conditions — no wearables to ship, and fewer data gaps between visits — via SDK integration or a white-labeled companion app.
Your device deserves data that reflects its clinical value
Office visits miss most of what happens between appointments, and patient-reported outcomes can be inconsistent. Sentinel is designed to make real-world evidence collection practical — turning a patient's smartphone into a source of objective movement information for your team to review.
How it works
Collect objective outcome data at scale
- 01
Capture movement continuously
Embed the Sentinel SDK into your existing mobile app, or deploy a white-labeled companion app, to passively collect gait, balance, and mobility information.
- 02
Review functional status over time
Track changes in functional status, device fit, and recovery trajectories through longitudinal mobility review. Notifications support your team's own interpretation.
- 03
Build longitudinal evidence at scale
Assemble real-world movement information across patient populations to inform device iterations and support regulatory submissions within their approved scope.
See changes as they emerge
Measure before intervention, throughout recovery, and during long-term device use. Subtle gait changes can help your team see who may be improving and who may warrant a closer look.
- Objective functional measures
- Longitudinal mobility review
- Early visibility of change
- Remote data collection
Keep patients engaged with progress
Showing objective progress can help patients stay engaged when their subjective sense of recovery doesn't match the clinical picture.
- Walk Score visibility
- Higher reported engagement
- Support for adherence
- Reduced dropout
Support coverage decisions
Provide clear, traceable documentation that supports the clinical rationale for device use, upgrades, or replacements. Coverage and reimbursement depend on payer rules and jurisdiction.
- Traceable documentation
- Support for payer review
- Clearer justification
- Deployment-specific results
Support product development
Analyze a broad set of validated gait and mobility parameters in real-world patient environments to inform development. Study timelines vary by design and deployment.
- Deployment-specific timelines
- Validated gait parameters
- Real-world data
- Regulatory-scope support
