Q

Describe the mechanics of a positive screening test outcome caused by the middle scalene muscle being tight.

A

Middle scalene. positive travell’s test.
the tight middle scalene pushes the neuro vascular bundle against the ant. scalene and causes the pulse to drop out or weaken and a possible recreation of symptoms. if negative, take a deep breath in to contract mid scalene making it push even more firmly against the neuro vascular bundle.

Q

Describe the mechanics of how a slump test may present positive based on a picture of the lumbar disc pushing posterior lateral.

Q

Describe the mechanics of a screening test used to assess for inflammation of the supraspin tendon.

A

Supraspinatus tendon - Drop arm testing
Pressure on the abducted humerus, causes deltoid to contract pulling the head of the humerus superior in the glenoid fossa, putting pressure against the acromion process pressing on the sub acromial burssa and the suprasinatis tendon.

Q

Describe the mechanics of the screening test used to assess for impingement of the costcoclavucular nerovascular bundle of nervous tissue.

A

Military brace, costal clavicular impingment of the neuro vascular bundle.
Trying to irritate the neuro vascular bundle by compressing it between the clavicle and the ribs by hyper extending the GH, causing anterior tilt of the scapula and pushes the clavicle down onto the first rib. deep breath in brings the rib closer to the clavicle furthering the pressure or making the space even more narrow.

32
What represents the typical/ most likely biomechanics of muscle strain in the cervical region?
Eccentric loading while the muscle is lengthened by an external force
33

True

good extension
55

longer
56
cervical TPs are, _____________and project_____/_____
short, anterior/lateral at a 45 degree angle
57
Flexion of the C-Spine specific kin:
-SCM,Longus Colli, sclene contract -Motion occurs inferior to superios segments -segments translate anterior -along a Z axis on a horizontal plane -The discs displace poserior -The erector spinae muscles eccentrically contract to control rate and speed of motion. -The facet joints open and the SPs distract.
58
Extension Of The Cervical Spine specific kin
-The Erector spinae muscles perform a short concentric contraction to move the head outside the line of gravity. -Motion occurs from the inferior to the superior segments -Each segment translates posterior along a Z axis and on a horizontal plane -The discs displace anterior -SCM, Longus Colli and scalenes eccentrically contract to control rate and speed of motion -The facet joints close
59
Side Bending C-Spine kin
-Side bending occurs on a frontal plane around a z axis -The disc displaces to the opposite side -The force is gravity and control is eccentric contraction of the erector spinae, trapezius and scalene on the opposite side. -This motion is limited in the cervicals due to the structure of the vertebral bodies and the TPs proximity to each other
60
Side Bending And Rotation - remember
We must note that the primary muscles involved in these motions will switch, depending on which motion is introduced first
61
Rotation Of The Cervical Spine specific Kin
-This motion occurs on a horizontal plane, around a Y axis -The force is muscular contraction of the trapezius, multifidi and rotatores -Control is accomplished through eccentric contraction of the corresponding muscled on the contrallateral side
62
Rotation and Sidebending From Flexion
-In Flexion the facets are open -Sidebending will close the facets on the side of motion -because of attachments of the cervicis muscles rotation will occur to the same side (non-neutral mechanics)
63
Rotation and Sidebending From Extension
-In extension the facets will be closed -Sidebending will open the facets on the side opposite the motion -Because the muscles concentrically contracting on the side of motion cause rotation to that side (the cervicis muscles), rotation again occurs to the same side (non-neutral mechanics)
