Clinical Presentation[edit | edit source]
The clinical presentation of lumbar radiculopathy will vary depending on the cause of the radiculopathy and which nerve roots are being affected. Patients will often present with pain in the lumbar region that radiates through one or both legs. This pain is often described as burning, stabbing, or shooting. For this pain to be considered radiculopathy, however, neurological signs must be present such as weakness, numbness, or reflexive changes. The following chart may be useful in identifying radiculopathy clinically.
Question | +LR (yes) | -LR(no) |
Weakness? | 1.2 | .73 |
Numbness? | 1.0 | .94 [1] |
See test diagnostics page for explanation of statistics.
Special Tests:
- Straight leg raise test (http://www.youtube.com/watch?v=u3wkt2KU6lU)
- Crossed straight leg raise test
Clinical presentation for radiculopathy from each lumbar nerve root:
Nerve Root | Dermatomal area | Myotomal area | Reflexive changes |
L1 | Inguinal region | ||
L2 | Anterior mid-thigh | Hip flexors | |
L3 | Distal anterior thigh | Hip flexors and knee extensors | |
L4 | Medial lower leg/foot | Knee extensors and ankle dorsiflexors | Patellar reflex |
L5 | Lateral leg/foot | Hallux extension and ankle plantar flexors | |
S1 | Lateral side of foot | Ankle plantar flexors and evertors | Achilles reflex [1] |
- Dermatomes and myotomes aren't intended as an all-inclusive list, but rather a clinically relevant system to assist in neurological screening.
