The term goniometry derives from two Greek words, γωνία 'angle' and μέτρον 'measure'. [1] The protractor is a commonly used type in the fields of mechanics, engineering, and geometry. The first known description of a goniometer, based on the astrolabe , was by Gemma Frisius in 1538.
Analog and traditional devices to measure range of motion in the joints of the body include the goniometer and inclinometer which use a stationary arm, protractor, fulcrum, and movement arm to measure angle from axis of the joint. As measurement results will vary by the degree of resistance, two levels of range of motion results are recorded in ...
The Spencer technique (also known as the "7 stages of Spencer") is an articulatory technique used in Osteopathic medicine to help relieve restriction and pain at the shoulder. [1] Although variations exist, normally 7 steps are included. [2] Indications for the Spencer technique include adhesive capsulitis. [3] The following is a common ...
In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder , thus decreasing the angle between the upper arm and the forearm .

A positioning goniometer or goniometric stage is a device used to rotate an object precisely (within a small angular range) about a fixed axis in space. Its appearance is similar to that of a linear stage .
In both tests, the patient is placed in a standing or sitting position, and the arms are raised parallel to the ground in the scapular plane. [2] The tests differ in the rotation of the arm; in the empty can test, the arm is rotated to full internal rotation (thumb down) and in the full can test, the arm is rotated to 45° external rotation, thumb up.
