Wrist rigidity evaluation device for deep brain stimulation surgery

摘要

It is disclosed an articulation rigidity assessment device for assessing the rigidity of the articulation when a bending motion is imposed to a limb of said articulation around a predetermined rotation axis of the articulation, said device comprising: a one-axis angular velocity sensor for attaching to said limb such that the axis of measurement is parallel to the axis of rotation of the imposed bending motion; a data processor configured to process the signal of the angular velocity sensor and to distinguish between non-rigid and rigid states of the articulation using the processed angular velocity signal. The articulation may be the wrist articulation of the patient and the limb is the respective hand. The device may comprise a skin-contacting patch for applying to the limb of the patient wherein the one-axis angular velocity sensor is attached to said skin-contacting patch. The skin-contacting patch may be applied to the palm or back of the hand.
