Hypermobility Assessment Tool

The HAT app can be used to screen for potential generalized joint hypermobility using the Beighton Score. By submitting 9 short videos of yourself performing simple movements, the HAT app will provide you a preliminary assessment of whether you may have joint hypermobility. The HAT app does NOT diagnose generalized joint hypermobility. The HAT app is a clinical support tool. It does not provide medical diagnoses or treatment recommendations and is not a substitute for professional medical judgment. Always seek the advice of a qualified healthcare provider with questions about your health.

The Hypermobility Assessment Tool (HAT) is a Health Canada Class I Medical Device and is distributed by the University Health Network (UHN). The app is not a substitute for medical care. If you are experiencing a medical emergency, please proceed to your local emergency dept.

The HAT app does not connect to your medical record in any way. Any results obtained by the HAT app will not be shared with your doctor or medical team unless you choose to share these results outside of the app.

Disclaimer:
The HAT app is designed as a preliminary screening tool for joint hypermobility and may yield higher scores than those obtained during an in-clinic assessment. This is expected. Based on validation testing, approximately 75–80% of individuals who receive a HAT score of 4 or more may score below 4 when assessed in clinic. Conversely, individuals who receive a score of 3 or less on the HAT app have a 3–5% likelihood of scoring 4 or greater in clinic.

Only a physical examination performed by a qualified healthcare provider at an EDS clinic should be considered the definitive assessment of joint hypermobility.
The HAT app is a clinical support tool. It does not provide medical diagnoses, treatment recommendations, or replace professional medical judgment. Patients should always consult their healthcare provider for personal medical advice and care decisions.
