A first sensor device is configured to be successively attached to each of a wrist carrier, an ankle carrier, and a headset carrier. The carriers are attached to, or positioned next to, the relevant portion of the patient's body in order to perform particular measurements relating to generating a BASMI score. As the patient performs the routine of motions associated with a particular BASMI measurement, the sensor device records the measurements and communicates the measurements to a user computing device. A second sensor device is configured to be applied to the patient's torso and an additional measurement of patient flexibility taken and communicated to the user computing device. The user computing device generates a BASMI score from the recorded measurements.

Abstract: Devices, systems and methods for reducing migration of leads, catheters and similar devices are provided. In particular, devices, systems and methods are provided for creating a slack anchor which assists in maintaining the lead or catheter in a desired position. In some embodiments, the slack anchor is created within the epidural space. When targeting nerve anatomy within the spinal column or in the vicinity of the epidural space, anchoring within the epidural space allows the associated lead or catheter to be anchored as close to the target therapy site as desired or possible. By anchoring close to the target therapy site, the risk of movement or migration is significantly reduced or eliminated.

Abstract: Signal analysis in an implanted cardiac monitoring and treatment device such as an implantable cardioverter defibrillator. In some examples, detected events are analyzed to identify changes in detected event amplitudes. When detected event amplitudes are dissimilar from one another, a first set of detection parameters may be invoked, and, when detected event amplitudes are similar to one another, a second set of detection parameters may be invoked. Additional examples determine whether the calculated heart rate is “high” or “low,” and then may select a third set of detection parameters for use when the calculated heart rate is high.
