Modern rehabilitative therapy motion capture systems perform goniometry at the very least measuring active range of motion. [11] While in some cases accuracy may be inferior to a goniometer, measuring angles with a motion capture system is superior at measuring during dynamic, as opposed to static situations.
Measured EMG potentials range between less than 50 μV and up to 30 mV, depending on the muscle under observation. [citation needed] Typical repetition rate of muscle motor unit firing is about 7–20 Hz, depending on the size of the muscle (eye muscles versus seat (gluteal) muscles), previous axonal damage and other factors. Damage to motor ...

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 ...
Spurling's test is somewhat specific when used for individuals with an abnormal electromyogram study and is a relatively sensitive physical examination maneuver in diagnosing cervical spondylosis or acute cervical radiculopathy. It is not a very sensitive test when used for individuals without classic radicular signs suggestive of cervical ...
The approximate conclusion was that an about equal amount of energy would have been used up. Elongated cervical ribs are skeletal evidence for a strong core to support the neck and limit its movement when walking. The study supports the idea that during times of drought and famine, an upright neck was crucial for these sauropods to survive. [3]
A subject must have adequate cervical spine range of motion to allow neck extension, as well as trunk and hip range of motion to lie supine. From the previous point, the use of this maneuver can be limited by musculoskeletal and obesity issues in a subject. [4]
