Pretest 1. Which structures in the cervical region are the most frequent cause of chronic pain? a) the occipital muscles b) the supraspinous ligaments c) the scalene muscles d) the sternocleidomastoid muscles 2. The most frequently injured ligament in the neck is the C4 supraspinous ligament. True or False? 3. The term whiplash refers to a specific injury. True or False? 4. Ligament injuries in the lower neck can cause headaches. True or False? 5. Most of cervical rotation takes place at the C5 vertebra. True or False? 6. Cervical ligament injuries can cause pain in the hand. True or False? 3

4 The Neck A Vulnerable Area Second most frequent site of injury Cervical pain affects 50 to 100 million Americans Often begins in an accident Most common is whiplash What is Whiplash? Sudden, physical action of accelerationdeceleration force Can damage various structures in the neck Usually posterior-anterior, resulting from a rear-end collision Often accompanied by concussion 4

5 Neck pain can be triggered by: 1. Overstretching the neck 2. Body use on the job 3. Lack of exercise 4. Poor body use Anatomy 5

6 Muscles Occipital muscles of the neck Splenius cervicis and splenius capitis Sternocleidomastoids Scalenes Ligaments Supraspinous Supraspinous Ligament 6

7 Ligaments Interspinous Interspinous Ligament Ligaments Intertransverse Intertransverse Ligament 7

8 Discs Damaged intervertebral discs press into cervical nerves Cause severe, longlasting pain Involved in only 3-5% of neck injuries Muscles vs. Ligaments vs. Discs Muscles: Frequent cause of immediate, temporary pain Discs: Occasional severe, long-lasting injury Ligaments: Most common cause of chronic neck pain especially at C4, C5, and C6 8

9 Assessment Tests Neck Assessment Tests Be sure the client sees a physician to test for serious damage Active tests: check for pain and limitation Passive tests: primarily assess the ligaments Resisted tests: assess the muscles 9

10 Active Tests Tests 1 2: Active rotations 10

11 Tests 3 4: Active side flexion Test 5: Active flexion 11

12 Test 6: Active extension Passive Tests 12

13 Tests 7 8: Passive rotations Test 9: Passive flexion 13

14 Test 10: Passive extension Resisted Tests 14

15 Tests 11 12: Resisted rotations Tests 13 14: Resisted side flexions 15

16 Test 15: Resisted flexion Test 16: Resisted extension 16

17 Normal Range of Motion Rotation: 90º Side flexion: 45 60º Flexion: chin to chest Extension: face parallel to ceiling Theory 17

18 Understanding the Assessment Test Results Muscle injury: Pain on resisted testing Ligament injury: Pain and limitation on passive testing (most commonly rotation; also flexion and extension) Disc injury: More complex results weakness, reflex changes, numbness, asymmetrical limitation of movement Mechanisms of Whiplash Forceful neck hyperextension followed rapidly by hyperflexion Causes tears in ligamentous and muscle tissues Leads to chronic scar tissue pattern 18

19 Other Symptoms of Whiplash Headache (can become chronic) Shoulder pain Scapula pain at the medial border Dizziness Fatigue Jaw pain Arm pain Visual disturbances Tinnitus (ringing in the ears) Weakness in the arm In chronic cases various emotional states can include: depression, anger and frustration Other Common Mechanisms of Cervical Injury No use, then sudden use 19

20 Other Common Mechanisms of Cervical Injury Spondylolisthesis Other Common Mechanisms of Cervical Injury Poor head and neck alignment 20

21 Other Common Mechanisms of Cervical Injury Loss of neck flexibility Common Injury Patterns Most common: supraspinous ligaments (especially at C5) Sternocleidomastoid, splenius cervicis, and splenius capitis often painful and sore for a few weeks Injured muscles heal quickly Injured ligaments do not 21

22 Commonly Injured Structures Vary by Body Area Thigh: Muscles Shoulder: Tendons or joint Neck: Ligaments (supraspinous and sometimes intertransverse) Referred Pain Patterns in the Neck 22

23 Referred Pain Patterns in the Neck Treatment 23

24 Friction Therapy Myofascial Therapy 24

25 Craniosacral Therapy Massage Therapy 25

26 Osteopathic or Chiropractic Manipulation Alexander Technique Feldenkrais Method 26

27 Exercise Therapy (restoring full range of motion) Flexibility Exercises 27

28 Occipital muscle tension The Neck Relaxer Device Post-test 1. Which structures in the cervical region are the most frequent cause of chronic pain? a) the occipital muscles b) the supraspinous ligaments c) the scalene muscles d) the sternocleidomastoid muscles 2. The most frequently injured ligament in the neck is the C4 supraspinous ligament. True or False? 3. The term whiplash refers to a specific injury. True or False? 4. Ligament injuries in the lower neck can cause headaches. True or False? 5. Most of cervical rotation takes place at the C5 vertebra. True or False? 6. Cervical ligament injuries can cause pain in the hand. True or False? 28
