    1. Physical Examination of the Lumbar Spine Chapter 9

    2. Overview Anatomy History Observation Palpation Neurologic exam Circulatory exam Special tests

    3. Anatomy Five lumbar vertebrae Five pairs (10 total) facet joints Intricate ligamentous support Anterior & posterior longitudinal Interspinous & supraspinous

    4. Anatomy Intervertebral disks Annulus fibrosus Outer zone (Sharpey’s fibers) Intermediate zone Inner zone 20 concentric collar like rings criss-crossed for strength Nucleus pulposus Fluid gradually changes to fibrocartilage

    5. Anatomy Erector spinae Latissimus dorsi Obliques Trapezius Segmental muscles Interspinales Intertransversarii Rotatores Abdominals Illiopsoas Hamstrings Quadriceps

    6. History: MOI What was the mechanism of injury? Was there a blow to the back? Did you hear or feel anything at time of injury? Was there any neck involvement? Were you twisting or bending at time of injury?

    7. History: Pain How did the symptoms begin? How soon after did you feel something? Where is the pain? Is the pain sharp or dull? Constant or intermittent? Localized or diffuse? Aggravated by movement?

    8. History: Pain (cont.) Relieved by rest? Are there any abnormal sensations such as numbness, tingling, burning, or radiating pain? Paralysis or paresthesia? Did the symptoms occur right away or later? Do you have any problems sleeping? What type of activity causes pain? Is the pain affected by laughing, coughing, or sneezing?

    9. History: Previous injuries Was there any previous injury? What was the assessment? What was the treatment? Were you fully recovered?

    10. Observation Deformities Movement and position Signs of trauma Skin color Skin temperature

    11. Observation Abnormalities Alignment of neck and back Iliac crest Leg length Scoliosis Winged scapula Forward head

    12. Observation Torticollis or wryneck Lordosis Kyphosis Compare Shoulder height

    13. Observation Symmetry Muscle spasm ASIS PSIS

    14. Observation: ROM Flexion Extension Left and right lateral flexion (“sidebending”) Left and right rotation

    15. Palpations: Bone Spinous process Transverse process Scapula SI joint Sacrum Coccyx Iliac crest ASIS PSIS Sciatic notch Ischial tuberosity

    16. Palpations: Soft tissue Supraspinous ligaments Infraspinous ligaments Paraspinal muscles Anterior abdominal muscles

    17. Neurologic Exam: Sensory Sensory dermatomes C2-C3: Occipital area and angle of jaw C4: Supraclavicular area Axillary Nerve Patch: Lateral aspect of shoulder C5: Lateral upper arm C6: Lateral forearm, thumb, and index finger C7: Middle finger and palmar aspect of hand C8: Small finger, ring finger, and medial portion of palmar surface
