GIMA Goniometer With Arms (27338)

To measure analytical motility of various body segments in degrees (from 0 to 360 clockwise or anti-clockwise direction).

Consists of two perspex arms (30 cm long, 3 mm thick) that will remain open at any given position due to the friction at the joint between them.

Two graded scales: one increasing scale and one decreasing scale.

Instructions

One of the two arms can be indifferently used as “fixed” arm.

Place the “fixed” arm on the intra-articular line of the body segment, which will remain still.

Make the patient move and rotate the other arm of the goniometer until it reaches the intra-articular line of

the moving segment or a parallel line.

On the graduated scale read the angle measure corresponding to the movement performed.

To adjust the friction between the two arms, turn the screw (clockwise to tighten it and counterclockwise

to loosen it) while keeping the self-locking nut still.

Instrument Accuracy

The maximum absolute error is equal to 1 degree.
