Goniometers and Torsiometers

The comprehensive range of Biometrics' Electrogoniometers and Torsiometers are ideal for quick, simple, and accurate measurement of joint movement in multiple planes. Extremely robust, lightweight and flexible, the sensors can be comfortably worn undetected under clothing, without hindering the actual movement of the joint.

The twin-axis Goniometers and single-axis Torsiometers provide improved mechanical integrity and electrical performance.

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 (Q110 and Q150)

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.
