Neck & Spine Movements

• Neck extension• Neck flexion• Neck rotation• Neck lateral flexion• Trunk extension• Trunk flexion• Trunk rotation

Terminology

• Unilaterally: to one side• Superficial: close to the body’s surface• Deep: away from the body’s surface• Trunk: mid-portion of body excluding

arms, legs, and head

Neck Flexors

• Sternocleidomastoid• Scalene

Neck Flexors

Sternocleidomastoid

Scaleni

Neck Extensors

• Upper trapezius• Deep spine and neck muscles

Neck Lateral Flexion

• All muscles on one side of the vertebral column contracting unilaterally.

Neck Rotation

• Occurs when the sternocleidomastoid, Scalenes, and other neck flexors contract on the opposite side of the direction of rotation

Trunk Flexion

• Lengthening of the deep and superficial back muscles and contraction of the abdominal muscles and hip flexor muscles.

Trunk Extension

• Lengthening of the abdominal muscles and the contraction of the erector spinae and the strongest hip extensor, the gluteus maximus.

Trunk Rotation

• Produced by the external oblique and internal oblique

Trunk Lateral Flexion

• Produced by the quadratus lumborum muscle and the obliques, and rectus abdominus on the side of the direction of movement.

SPRAINS AND STRAINS OF THE NECK & SPINE

Terminology

• Cervical collar: soft brace that fits around an athletes’ neck

• Intermittently: alternating stopping and beginning again

• Radiating: to spread out in a direction from the center

Cervical Sprain• Despite having an excellent Range of Motion, it is

subject to ligament sprains when it is forcefully moved beyond its normal range.

• MOI: – turning head to catch a ball and then athlete gets

tackled by a defender. When hit forcefully from behind, the receiver often suffers a whiplash injury. The body is forced forward by the blow while the head moves backward which places the cervical spine into extension and stretches the ligaments and muscles at the front of the neck.

Cervical Sprain: S/S

• Usually intense pain if sprain is located in the neck• Palpation of the injured area is

usually painful if the joint is sprained

Neck Strain: Rx

• Rest• Ice (twenty minutes intermittently 6-8

times a day) • Cervical collar if warranted• Perform spinal tests to rule out

possible paralysis• Refer to doctor if needed

Neck Flexors

Sternocleidomastoid

Scaleni

Cervical Nerve Stretch Syndrome “Burner”: MOI

• Head is forced into a lateral position while athlete’s arm is pulled in the opposite direction

Cervical Nerve Stretch Syndrome “Burner”: S/S

• Typically athlete walks off the field with his neck pulled toward the side and the athlete is supporting his arm

• This mechanism of injury can result in burning, tingling, numbness, and stinging sensations• Athlete may recover in seconds or minutes

Cervical Nerve Stretch Syndrome “Burner”: Rx

• Watch athlete carefully • Athlete monitors the intensity of the burning • Between 2-5 minutes the intensity should lower

dramatically or disappear • Manual muscle test for strength and parethesia• Athlete stretches neck muscles, shoulder

muscles and prepares to re-enter game/practice.• Instruct athlete to see athletic trainer after

competition is over to re-check his/her neck

Low Back Muscle Strains: MOI

• Sudden rotation and contraction on an overloaded, unprepared or underdeveloped spine.

Low Back Muscle Strains: S/S

• Discomfort in low back may be diffused or localized in one area

• Pain will be present on active extension and with passive flexion

• No radiating pain

Low Back Muscle Strain: Rx

• Ice 20 minutes 4-6 times a day• Gradual stretching and progressive

strengthening once pain has subsided

Lumbar Sprain: MOI

• Typically occurs when the athlete bends forward and twists while lifting or moving some object. A traumatic force over extends the spinal joints and causes a sudden onset of deep sharp pain.

Lumbar Sprain: S/S

• Pain is localized • Located just lateral of the spinous process• Pain becomes sharper with certain

movements• Any anteroposterior or rotational movement

increases pain

Lumbar Sprain: Rx• R.I.C.E• Athlete may have to wear a supported brace• Stretching in all directions, (ROM) should be limited to a

pain free range• Once appropriate, strengthening exercises for

abdominals and back extensors should be initiated • Doctor referral may be indicated

FRACTURES & DISLOCATIONS OF NECK & SPINE

Terminology

• Spearing: Athlete uses top of the helmet to hit another athlete

• Axial Loading: a force delivered to the top of a straight column of vertebrae

Cervical Spine Fracture/Dislocation: MOI• Often the result of combination of excessive

neck flexion and rotation

• Axial loading of the cervical vertebrae from a force to the top of the head combined with flexion of the neck can result in a fracture or dislocation

http://www.cyclenews.com/articles/industry-news/2009/11/04/neck-protection-let-s-talk-about-it/full

Cervical Spine: S/S

• Athlete reports pain around cervical spine • Weakness• Numbness• Tingling down the arms• With a dislocation, there is often a visible deformity • Pain in the chest• Numbness in the trunk or limbs • Sometimes loss of bladder and/or bowel control

Cervical Spine: Rx

• If signs and symptoms present possibility of a fracture or dislocation call 911 for assistance

• For both a fracture and dislocation often care for

both injuries as identical

• After ruling out life-threatening conditions the neck should be immobilize and athlete should be put on a spine board

FRACTUREE

CHRONIC INJURIES OF THE NECK & SPINE

Ostephytes: outgrowth on a bone

Disk bulge: disk moves out between the two vertebrae causing pinching of the disk

Impinge: to come into contact with a nerve or disk causing a pinching action

Transitory: not lasting, temporary

Posterolateral: in the combined direction of posterior and later movements

Extrudes: to thrust out

Idiopathic: unknown cause

TERMINOLOGY

Spinal Stenosis

Characterized by a narrowing of the spinal canal in the cervical region that can impinge the spinal cord

Spinal Stenosis MOI:– Either a congenital defect or development of bone spurs

osteophytes or disc bulges

S/S:– Transient quadriplegia may occur from axial loading,

hyperextension, or hyperflexion– Neck pain my be absent initially – Symptoms may be burning and tingling or associated

motor weakness in the arms and legs– Complete recovery normally occurs within 10-15 minutes

Spinal Stenosis: Rx• If athlete demonstrates transient quadriplegia the

athletic trainer should use extreme caution initially • Athlete must have diagnostic test including x-rays or

MRI• If identified as having cervical spinal stenosis, athlete

should be advised of the potential risks of continued participation

• Physicians release is required to return to participation

Cervical Disk InjuryMOI:– Sustained, repetitive cervical loading during contact

sports. The disk extrudes posterolaterally

S/S:– Neck pain with some restriction in neck motion– Pain in upper extremity with associated functional

weakness or sensory changes– Possible activation of EMS

Cervical Disk Injury: Rx

• Rest and immobilization of the neck to decrease discomfort

• Physician referral recommended

• Cervical traction may also help reduce symptoms

Low Back Pain

MOI: Either caused by a congenital or idiopathic defect.

S/S: Localized or diffused pain in the low back– Low back muscles may be weak – Range of motion for back may be painful– Athlete may become discouraged with symptoms

because they may last a long time

Low Back Pain: Rx

• Dependent on athlete’s pain tolerance, he/she may continue with regular practice or be in complete rest

• Alternating ice pack and heat pack (20 minutes)

• Low back muscular stretching with athletic trainer

• Athletic trainer teaches and demonstrates exercises the athlete should do at home

Herniated Disk: MOI

• Develops from extruded posterolateral disk fragment or from degeneration of the disk

• Primary mechanism involves sustained, repetitive cervical loading during contact sports

Herniated Disk: S/S

• Neck or back pain

• Pain may be restricted or diffused

• Restriction in neck movement

• At some point in the range of motion of the back and neck the herniated disk may become impinged causing extreme pain

Herniated Disk: Rx

• Initial treatment involves rest and immobilization of the neck to decrease discomfort

• If discomfort is in the lumbar area, rest and an immobilization brace may be helpful

• Cervical traction may help reduce symptoms • If this conservative treatment does not help surgical

intervention may be necessary
