Forearm motions; Upper arm motions; Shoulder motions; Momentum should be employed to assist the worker whenever possible, and it should be reduced to a minimum if it must be overcome by muscular effort. Smooth continuous motions of the hands are preferable to zigzag motions or straight-line motions involving sudden and sharp changes in direction.
The International Federation of Orthopaedic Manipulative Physical Therapists defines joint mobilization as "a manual therapy technique comprising a continuum of skilled passive movements that are applied at varying speeds and amplitudes to joints, muscles or nerves with the intent to restore optimal motion, function, and/or to reduce pain." [1]
The larger scales of imperceptible motions are difficult for humans to perceive for two reasons: Newton's laws of motion (particularly the third), which prevents the feeling of motion on a mass to which the observer is connected, and the lack of an obvious frame of reference that would allow individuals to easily see that they are moving.

An experiment from Harvey's Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus. Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus (Latin, 'An Anatomical Exercise on the Motion of the Heart and Blood in Living Beings'), commonly called De Motu Cordis, is the best-known work of the physician William Harvey, which was first published in 1628 and established the ...
Pronation is the motion of the inner and outer ball of the foot with the heel bone. [13] One is said to be " knock-kneed " if one has overly pronated feet. It flattens the arch as the foot strikes the ground in order to absorb shock when the heel hits the ground, and to assist in balance during mid-stance.
Continuous passive motion (CPM) devices are used during the first phase of rehabilitation following a soft tissue surgical procedure or trauma. The goals of phase 1 rehabilitation are: control post-operative pain, reduce inflammation, provide passive motion in a specific plane of movement, and protect the healing repair or tissue.
The following 9 degrees of active articulatory areas are known to be contrastive (sorted such that the top-most is in the front-most area of the mouth and the bottom-most is in the rear-most area of the mouth): [1]: 10-15 The lower lip ; Various parts of the front of the tongue : The tip of the tongue
Passive range of motion (or PROM) – Therapist or equipment moves the joint through the range of motion with no effort from the patient. Active assisted range of motion (or AAROM ) – Patient uses the muscles surrounding the joint to perform the exercise but requires some help from the therapist or equipment (such as a strap).
