Definition : Electromechanical measuring instruments designed for automated measurement of angular twisting (i.e., rotations in one plane), rather than bending. These torsiometers typically consist of small-diameter flexible spring with plastic end blocks and a strain gauge mechanism housed inside the spring that changes electrical resistance proportionally to the change in angle between the longitudinal axes of the end blocks, an amplifier, and extension cables to connect to the electronic measuring unit. The end blocks are attached to limb segments with double-sided adhesive tape. Torsiometers are mainly intended to measure angular torso, forearm, neck, and spine twisting; they are used by rheumatologists and physiotherapists.
