    • Techniques for controlling therapy delivery based on the relative orientation and/or motion of a device accelerometer and a lead accelerometer are described. In one embodiment, a therapy system includes an electrical stimulator and a lead. The electrical stimulator comprises a processor that controls delivery of a therapy to a target stimulation site in a patient and a device accelerometer coupled to the electrical stimulator. The lead is coupled to the electrical stimulator to deliver the therapy from the electrical stimulator to the target stimulation site in the patient, and includes a lead accelerometer. The processor compares signals from the accelerometers, and controls delivery of the therapy to the patient based on the comparison. In this manner, the processor may adjust stimulation to, for example, address movement of electrodes relative to target tissue when a patient changes postures.
    • 描述了基于设备加速度计和线加速度计的相对取向和/或运动来控制治疗递送的技术。 在一个实施例中,治疗系统包括电刺激器和引线。 电刺激器包括处理器,其控制对患者的目标刺激部位的治疗传递和耦合到电刺激器的装置加速度计。 引线耦合到电刺激器以将治疗从电刺激器传递到患者中的目标刺激部位,并且包括引线加速度计。 处理器比较来自加速度计的信号,并且基于比较来控制对患者的治疗传递。 以这种方式,当患者改变姿势时,处理器可以将刺激调整为例如电极相对于靶组织的地址移动。
