Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another. In biomechanics and strength training , ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. [ 1 ]
PPIVM is used as an assessment technique to assist with identifying the location, nature, severity and irritability of vertebral symptoms. They can be used to test for cervical or lumbar joint hypermobility or instability, or whether a joint is locked. PPIVM assessments test the movement available at a specific spinal level through the ...
Goniometer made by Develey le Jeune in Lausanne, late 18th–early 19th century. A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position.
Its primary function is the flexion of the fingers, and this is used as the clinical test for C8 integrity, in conjunction with the finger jerk reflex. [ 4 ] The particular muscles receive innervation from C8 [ 3 ] (shown by specific nerve and spinal nerve segments; muscles in italics only have a minor contribution from C8) :
The number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.
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 .
[7] [8] Irradiation of the cervical spine may also evoke it as an early delayed radiation injury, which occurs within 4 months of radiation therapy. [citation needed] Delayed onset Lhermitte's sign has been reported following head and/or neck trauma.
The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient, it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps (checking both hip flexion and knee extension strength simultaneously).
