Abstract
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.
Claims18
A lower-body garment for identifying a human subject's physiologic susceptibility of ACL injury, comprising:
- a torso portion having a waist opening;
- a first leg portion and a second leg portion extending from the torso portion, the first leg portion defining a first leg opening and the second leg portion defining a second leg opening;
- one or more sensors coupled to the torso portion, the first leg portion and the second leg portion at locations proximate the human subject's hip and/or knees, configured to:
- measure a first value characterizing knee varus while a wearer of the lower-body garment is subjected to a stork test;
- and
- measure a second value characterizing hip extension while the wearer of the lower-body garment is subjected to the stork test;
- and
- communicate the first value and the second value to one or more computer processing components;
- one or more computer processing components coupled to the lower-body garment;
- a non-transitory computer-readable medium coupled to the one or more computer processing components, the non-transitory computer-readable medium comprising computer-executable instructions stored thereon that, when executed by the one or more computer processing components, cause the one or more computer processing components to:
- receive the first value and the second value from the one or more sensors;
- calculate a susceptibility score using a predetermined algorithm that processes the first value and the second value to determine a mean hip extension angle, a mean knee varus angle, and a mean hip abduction angle;
- and
- output the susceptibility score.
A device for monitoring susceptibility of injury to a lower extremity comprising:
- a housing for retaining one or more sensors proximate to a wearer's hip and/or knees when in an as-worn configuration;
- one or more sensors to measure a first value characterizing hip extension and a second value characterizing knee varus while a wearer of the device is subjected to a stork test;
- and
- one or more computer processing components, wherein the one or more computer processing components comprise a machine-readable medium including executable instructions stored thereon which, when executed by the one or more computer processing components, implement a method for determining the susceptibility of lower extremity injury comprising:
- determining a mean hip extension angle;
- determining a mean knee varus angle;
- determining a mean hip abduction angle;
- generate a susceptibility score based at least in part on the first value, the second value, the mean hip extension angle, the mean knee varus angle, and the mean hip abduction angle;
- and
- causing a display on a user interface, the susceptibility score.
