摘要:
A portable quantification apparatus for assessing joint accessory movement is disclosed in the present invention. The apparatus includes a reference unit, a movement unit, a sliding unit and a displacement sensor. The reference unit has a first probe and a first force sensor. The movement unit has a second probe and a second force sensor. The sliding unit is disposed between the reference unit and the movement unit which allows the movement unit to slide alongside with the reference unit. When a patient is under a test, the first probe is against one of two adjacent bones of a joint, while the second probe is against the other adjacent bone. The first force sensor and the second force sensor sense a first force and a second force applying to the reference unit and the movement unit respectively. The displacement sensor measures a relative movement of the movement unit over the reference unit.
