- نبذة مختصرة :
Systems, devices, and methods are disclosed for the purpose of quantitatively determining the susceptibility of a human subject to injure their Anterior Cruciate Ligament (ACL). A method for determining injury susceptibility scores or risk categories includes determining hip extension angles and knee varus angles during the performance of a stork test and determining hip abduction angles during a squat test. Determination of angles during certain movements may be achieved using various systems and devices, including wearable devices.

- Claim:
1. A method for identifying a human subject's physiologic susceptibility of ACL injury, comprising steps of: determining a first value characterizing hip extension and a second value characterizing knee varus of a human subject while subjecting the human subject to at least one stork test; determining a third value characterizing hip abduction of the human subject while subjecting the human subject to a squat test; generating a susceptibility score, the susceptibility score comprising positively weighing the first value and the third value and negatively weighing the second value; and based on the susceptibility score being higher than a predetermined threshold, applying a corrective device to a knee of the human subject and administering physical therapy to limit the range of movement of the knee.
- Claim:
2. The method of claim 1 , further comprising: comparing the susceptibility score to one or more thresholds; and based on comparing the susceptibility score to one or more thresholds, determining a risk category indicating a likelihood of future ACL injury for the human subject.
- Claim:
3. The method of claim 2 , wherein the method further comprises: treating the human subject using mechanics therapy or devices to reduce stork hip extension, increase knee varus, and decrease squat hip abduction.
- Claim:
4. The method of claim 1 , wherein one or more of the first value, second value, and third value are determined using a markerless 3D camera.
- Claim:
5. The method of claim 1 , wherein one or more of the first value, second value, and third value are determined using a wearable device.
- Claim:
6. The method of claim 5 , wherein the wearable device comprises a garment.
- Claim:
7. The method of claim 5 , wherein the wearable device comprises a brace.
- Claim:
8. The method of claim 1 , wherein the first value comprises a mean of left hip extension and right hip extension, the second value comprises a mean of left knee varus and right knee varus, and the third value comprises a mean of left hip abduction and right hip abduction.
