MEASUREMENT DEVICE

摘要

A handheld measurement device (10) for enabling a user to measure a person's muscle strength and range of motion associated with a limb movement about a joint in a movement plane. The device comprises a contact surface (28) that is arranged to contact a part of the person's limb, a 3D orientation sensor that is arranged to sense the 3D orientation of the device in 3D space and generate representative 3D orientation signals during the limb movement, and a force sensor that is arranged to sense the force applied by the person's limb to the contact surface and generate representative force signals. A control system receives the 3D orientation and force signals and processes those signals to generate force data and angular rotation data.
