Goniometers and Torsiometers
Biometrics' sensors are sold separately or as part of complete measurement systems. Available systems include instrumentation for static angle readout, dynamic on line data acquisition in 8, 16, or 24 channel configurations, or fully portable wireless data collection systems.
Twin Axis Goniometers
Twin axis Goniometers (SG series) simultaneously measure angles in up to two planes of movement. For example, to measure wrist movements, the endblocks of the Goniometer are attached on the dorsal surface using double sided tape (T10), one end over the third metacarpal, the other over the midline of the forearm, with the wrist in the neutral position.
The Goniometer has two separate output connectors, one measures flexion/extension, the other radial/ulnar deviation. When used to measure a single axis joint such as the knee or elbow, or when measuring a single plane of a twin axis joint, simply connect one channel, the other remains redundant. All twin axis Goniometers function the same way, the difference being physical size.
Single Axis Goniometer
Biometrics' single axis Goniometer (F35) measures angles in one plane only. This smallest goniometer is designed to measure flexion/extension of finger or toe joints.
Single Axis Torsiometers
Biometrics Ltd single axis Torsiometers (Q series) are designed for measurement of rotations in one plane e.g. forearm pronation/supination or neck axial rotation. If the Torsiometer is bent in planes X-X or Y-Y the output remains constant. All Torsiometers function in the same way, the difference being physical size.
