It may be suboptimal functioning of the tested target muscle, or a normally optimally functioning muscle can be used as an indicator muscle for other physiological testing. A commonly known and very basic test is the arm-pull-down test, or "Delta test," where the patient resists as the practitioner exerts a downward force on an extended arm. [ 16 ]
These dynamometer measurements are more sensitive to change compared to manual muscle testing and render outcome on a continuous scale. In clinical evaluation and research studies on patients with hand problems, muscle strength measurements are usually based on grip strength and pinch strength dynamometry. The most commonly used grip and pinch ...
Chapman's physical exerciser. A second device, invented in 1937 by Arthur William Chapman would be used to create the Bullworker.. The patent states: The invention relates to physical exercisers for human use, and seeks to provide in a single device means whereby a large variety of beneficial exercises for the body and limbs may be carried out.
An exhibit of the "Future Soldier" designed by the United States ArmyA powered exoskeleton is a mobile machine wearable over all or part of the human body, providing ergonomic structural support, and powered by a system of electric motors, pneumatics, levers, hydraulics or a combination of cybernetic technologies, allowing for sufficient limb movement, and providing increased strength ...
Irvin Korr, J. S. Denslow and colleagues did the original body of research on manual therapy. [2] Korr described it as the "Application of an accurately determined and specifically directed manual force to the body, in order to improve mobility in areas that are restricted; in joints, in connective tissues or in skeletal muscles."

In humans myotome testing can be an integral part of neurological examination as each nerve root coming from the spinal cord supplies a specific group of muscles. Testing of myotomes, in the form of isometric resisted muscle testing, provides the clinician with information about the level in the spine where a lesion may be present. [ 7 ]
