Abstract: An exemplary system and method that non-invasively assess the effusion state of a joint via the use of a non-invasive measurement device. The measurement device actively interrogates the bone connected to the joint and nearby tissue with mechanical or acoustic energy by applying an impulse or vibratory mechanical or acoustic energy into the bone to assess the response of the bone at its connecting joint and its proximate tissue. The measurement device may additionally interrogate the bone connected to the joint and nearby tissue with electrical energy by applying an impulse or vibratory electrical energy into the joint (e.g., knee) or its nearby tissue to assess the electrical response of the joint and its proximate tissue. In some embodiments, the sensors employ both mechanical interrogation and electrical interrogation of the joint for the non-invasive assessment, e.g., for bioimpedance characteristics of the tissue and joint.
