Abstract: Lower extremity motion data may be received from one or more sensors. The lower extremity motion data may be used to quantify propulsion performance, which is used to calculate one or more gait characteristics of the lower extremity. A risk level of the lower extremity may be determined based, at least in part, on the calculated gait characteristics.

Abstract: A range of motion (ROM) removeable cast walker (RCW) has an ankle hinge that may be locked and unlocked by the user. A first sensor is responsive to the locked/unlocked condition of the RCW. A second sensor is responsive to the presence of a limb within the RCW. A third sensor is responsive to weight borne by the RCW. If the ankle hinge is unlocked, the ROM RCW is being worn and weight is being borne, a warning is provided to the patient to remind the patient to lock the ankle hinge to conform to the therapeutic regimen. A radio transmitter may report the state of the ROM RCW to a smart phone and to a remote storage facility for use by a physician.

Abstract: A game-based platform for exercise procedures for prevention of venous thromboembolism (VTE) may have a wearable sensor and human-machine interface technology configured to monitor and encourage VTE prevention exercises. The wearable sensor may attach to a patient's foot to monitor movement of the ankle joint, such as pronation, supination, dorsiflexion, or plantar flexion. The patient may be instructed to move their foot by operating their ankle to move a cursor around on a screen to reach a target. Targets may be randomly presented to keep the patient moving their foot for a specified duration of time.

Abstract: A lace tension-controlled compression sock that can be easily donned and removed and delivers the necessary amount of pressure to mitigate the effects of chronic venous disorders (CVDs) comprises easily read, graphic pressure indicators for use by the wearer when adjusting the degree of compression.
