An articulation rigidity assessment device comprises a single-axis angular velocity sensor attachable to a limb such that an axis of measurement is parallel to a predetermined rotation axis of a bending motion imposed during a dosage administration regime of a drug in order to identify a clinically effective dose as having been administered. A data processor is configured to process an angular velocity sensor signal during the dosage administration, calculate a non-rigidity index of the articulation using the processed signal, wherein the non-rigidity index is the square root of the multiplication of the average of the angular velocity signal by the average peak value of the angular velocity signal. The device outputs feedback of the non-rigidity index at a current dose of the drug, whereby the clinically effective dose is identified as having been administered as a function of the output. A method is also disclosed.

A sensor system includes an actuator, an accelerometer coupled with the actuator, a rigid member, a transducer, and one or more processors. The actuator generates motion. The accelerometer outputs an acceleration signal responsive to at least the motion of the actuator. The rigid member extends from a first end coupled with the accelerometer to a second end. The transducer is coupled with the second end of the rigid member. The transducer can be configured to couple with a load, and can output a force signal responsive to at least a portion of the motion of the actuator transmitted to the transducer via the rigid member. The one or more processors determine a mechanical impedance of the load based at least on the acceleration signal and the force signal.

Total energy shaping control methods and devices for powered orthosis for controlling the device to counteract forces exerted on the person including inertial forces.

A reverberant shear wave field in an object such as a patient's body or organ causes deformations in one or more selected directions measured with an imaging modality such as ultrasound or MR equipment or other imaging equipment, to estimate displacements in one or more selected directions over time increments and then viscoelastic properties such as stiffness or other parameters of the ROI.

The present invention relates generally to a system and method for measuring the structural characteristics of an object. The object is subjected to an energy application processes and provides an objective, quantitative measurement of structural characteristics of an object. The system may include a device, for example, a percussion instrument, capable of being reproducibly placed against the object undergoing such measurement for reproducible positioning. The system does not include an external on/off switch or any remote on/off switching mechanism. The system also includes a disposable feature or assembly for minimizing cross-contamination between tests. The structural characteristics as defined herein may include vibration damping capacities, acoustic damping capacities, structural integrity or structural stability.

A device can detect and retrieve a blood clot by advancing a catheter with a clot sensing element through a patient vascular. The catheter can map, using an electromagnetic sensor disposed at a distal end of the clot sensing element, the patient vascular. A force sensor can generate a position signal indicating the clot sensing element contacted the clot in the patient vascular. Once located, a blood clot retrieval device can be deployed through the catheter and a lumen in the clot sensing element to remove the clot from the patient vascular

A method of treating a sacroiliac joint including: approaching the sacroiliac joint with an implant including a sensor supported by a body; delivering the implant either a) non-transversely into the sacroiliac joint, b) transversely across the sacroiliac joint, or c) up to the sacroiliac joint without insertion therein, the sensor providing a signal that indicates a present condition of the sacroiliac joint; receiving an input from a sensory indicator based on the signal from the sensor, the sensory indicator being in communication with the sensor, and wherein the input from the sensory indicator provides data associated with the signal; and, treating an ailment of the sacroiliac joint based at least in part on the input.
