Location of Pain
• Often difficult to isolate specific location of pain with low back injuries/conditions
• Radiating pain indicative of nerve root irritation– Must have perspective on myotome/dermatome
patterns for evaluation– Regarding peripheral nerves, must have
perspective on nerve root level origin
4

Onset of Pain
• Acute, traumatic onset of symptoms, while possible, is not a typical presentation of low back pain symptoms
• May be able to isolate one incident with onset of symptoms, but typically that incident is representative of accumulative stresses over time which reach their “breaking” point
5
![Page 6: Kin191 A.Ch.10. Lumbar. Thoracic. Evaluation](https://reader033.vdocuments.mx/reader033/viewer/2022061122/54719be4b4af9fb90a8b4c08/html5/thumbnails/6.jpg)
Mechanism of Injury
• Direct trauma may indicate spinal fracture/s and/or internal organ injury
• Hyperextension activities (gymnastics, FB lineman, etc.) predispose to pars interarticularis injuries
• Multiple compression and shear forces depending upon activities engaged in
• Often difficult to isolate specific MOI
6
![Page 7: Kin191 A.Ch.10. Lumbar. Thoracic. Evaluation](https://reader033.vdocuments.mx/reader033/viewer/2022061122/54719be4b4af9fb90a8b4c08/html5/thumbnails/7.jpg)
Consistency of Pain
• Constant pain– If unable to affect pain with position change,
associated with inflammation from injury (acute or chronic) – swelling from facet sprain or pars interarticularis fracture
• Intermittent pain– If symptoms impacted (alleviated or aggravated)
with spine position, associated with mechanical injury – compression/stretching of nerve root
7
![Page 8: Kin191 A.Ch.10. Lumbar. Thoracic. Evaluation](https://reader033.vdocuments.mx/reader033/viewer/2022061122/54719be4b4af9fb90a8b4c08/html5/thumbnails/8.jpg)
Prior History
• Must question regarding previous history of low back injury/pain
• Structural or degenerative changes may predispose to symptoms
• Scar tissue may irritate tissues causing symptoms
8
![Page 9: Kin191 A.Ch.10. Lumbar. Thoracic. Evaluation](https://reader033.vdocuments.mx/reader033/viewer/2022061122/54719be4b4af9fb90a8b4c08/html5/thumbnails/9.jpg)
Aggravating/Alleviating Factors
• What makes it better? …worse?
• Posture/s– Prolonged sitting, etc. with activities
• Activities– May have postural component with performance
of activities
9
![Page 10: Kin191 A.Ch.10. Lumbar. Thoracic. Evaluation](https://reader033.vdocuments.mx/reader033/viewer/2022061122/54719be4b4af9fb90a8b4c08/html5/thumbnails/10.jpg)
Activity Changes
• As with many lower extremity injuries/conditions, must be mindful of changes in– Intensity of workouts– Duration of workouts– Training surface– Footwear– Sleeping arrangements
10
![Page 11: Kin191 A.Ch.10. Lumbar. Thoracic. Evaluation](https://reader033.vdocuments.mx/reader033/viewer/2022061122/54719be4b4af9fb90a8b4c08/html5/thumbnails/11.jpg)
INSPECTION
• Posture/Curvatures– Standing, sitting, with activities (e.g. – lifting)– Lateral shift away from pain/nerve root
impingement– Frontal curvature – scoliosis (see slide 14)– Sagittal curvature – excessive/absent lordosis
• Muscular appearance– Evaluate for spasm/atrophy – often readily visible
11
![Page 12: Kin191 A.Ch.10. Lumbar. Thoracic. Evaluation](https://reader033.vdocuments.mx/reader033/viewer/2022061122/54719be4b4af9fb90a8b4c08/html5/thumbnails/12.jpg)
• Gait• Skin markings– Café-au-lait spots (neurofibramatosis), Faun’s
beard (spina bifida)– Neurofibromatosis• Increased cell growth of neutral tissues; normally a
benign condition; pain possible secondary to pressure on the local nerves
– Spina bifida occulta• Incomplete closure of the spinal vertebrae

Scoliosis
• Forward flexion test– Posterior view of the spinal column while the
patient flexes the spine; note the presence of hump over the spine, suggesting scoliosis
– If functional, “hump” disappears– If structural, “hump” present

• Rotation– Knees/hips flexed and rotate pelvis with shoulders on
table

• Flexion– Stabilize pelvis, resistance to sternum with “crunch”
• Extension– Stabilize low back, resistance near scapula to “reverse
crunch”
• Lateral flexion/bending – typically not assessed• Rotation– Stabilize opposite ASIS, resistance to opposite shoulder for
“curl crunch”

SLR and Well SLR Tests• Evaluative for nerve root impingement,
typically discogenic in nature• SLR test– Supine, flex hip (SLR) on affected side to pain with
knee extended, back off a little, DF ankle, if symptoms reoccur, + test
• Well SLR test– SLR of opposite (uninvolved) leg, test + if pain felt
on opposite side

and rotates to affected side• If radiating pain, indicative of nerve root
irritation or impingement• If local pain with no radiating symptoms,
indicative of facet irritation/sprain

Slump Test
• Evaluative for nerve root, dural sheath or spinal cord irritation/inflammation
• Seated, cervical flexion and thoracic “slump” followed by knee extension and ankle dorsiflexion
• Pain and/or radiating symptoms are + test – due to neural element lengthening/stretch

Hoover Test
• Evaluative for malingering patient• Supine, clinician holding both heels, patient
instructed to perform active SLR on involved side
• Pressure should be noted in opposite heel by clinician – attempt to stabilize for movement
