- Foot Drop
- Cervical Myelopathy
- Ankylosing Spondylitis
- Neurofibromatosis & Scoliosis
- Spinal Stenosis
- Cervical Radiculopathy

Examination of the Spine
Look (Inspection)
- Expose fully.
- Assess from front and back for:
- Pelvic or shoulder tip asymmetry.
- Posterior rib cage prominence.
- Sagittal alignment (normal curves).
- Inspect skin:
- Stigmata of neurological disease.
- Scars.
- Muscle wasting.
- Observe specific areas:
- Shoulder girdle (C5/C6).
- Hand intrinsics (C8/T1).
- Calf/Quads (L3/S1).
- Gait Assessment:
- General inspection for Trendelenberg or ataxia.
- Heel-toe walking: Tests Tibialis Anterior (L4) and Gastrosoleus (S1).
- Pigeon walking: Assesses balance and early signs of myelopathy.
- Rhomberg’s Sign:
- Eyes shut, standing still.
- Excessive swaying indicates cerebellar lesion or myelopathy.
Feel (Palpation)
- Palpate spinous processes from occiput down.
- Check paraspinal musculature for spasm.
- Assess SI joints, hips, and shoulders for associated pathologies.
Move
- Assess range of motion (ROM) in cervical and thoracolumbar spine:
- Observe for pain, restriction, or radicular symptoms.
Provocative Tests
Cervical Spine
- Spurling’s Test:
- Extend and rotate head to affected side.
- Indicates nerve root entrapment.
- Lhermitte’s Sign:
- Flex and extend spine fully.
- Electric-like axial pain suggests myelopathy.
Lumbar Spine
- Straight Leg Raise (SLR):
- Dorsiflex ankle to stretch sciatic nerve.
- Cross-leg SLR:
- More sensitive than SLR.
- Bowstring Test:
- Flex hip with semi-flexed knee, reduce hip flexion slightly, and straighten knee.
- Femoral Stretch Test:
- Extend hip and flex knee while prone.
Neurological Examination
Motor Power (MRC Grades)
Grades: 0: No power. 1: Flicker of movement. 2: Movement with gravity eliminated. 3: Overcomes gravity but no resistance. 4: Overcomes some resistance. 5: Normal power.
Myotomes:
- C5: Deltoid, Biceps.
- C6: Wrist extension.
- C7: Wrist flexion.
- C8: Finger flexion.
- T1: Intrinsics, little finger abduction.
- L2: Hip flexion, adduction.
- L3: Knee extension.
- L4: Ankle dorsiflexion, Gluteus medius.
- L5: EHL, EDL.
- S1: Ankle plantarflexion.
Sensory Assessment
- Deep Pressure, Vibration, Proprioception: Dorsal columns.
- Pinprick: Spinothalamic tracts.
- Dermatomes:
- C3: Supraclavicular fossa.
- C4: Over ACJ.
- C5-C8: Arm and hand distribution.
- T1-T2: Medial arm/forearm.
- L2-S1: Lower limb.
- S2-S3: Posterior thigh, buttocks.
Reflexes
- C5: Biceps.
- C6: Brachioradialis.
- C7: Triceps.
- L4: Patella tendon.
- S1: Ankle jerk.
Myelopathy Signs
Hoffman’s Sign:
- Flick distal phalanx and observe reflexive thumb flexion.
Babinski Sign:
- Stroke lateral plantar aspect of sole. Big toe extension indicates UMN lesion.
Clonus: 5 beats suggests myelopathy.
Jaw Jerk: Striking mandible causes rapid movement; lesion above spinal cord.
Nonorganic Signs of Waddell
- Nonanatomic tenderness.
- Simulation signs (e.g., axial loading, rotation pain).
- Distraction test discrepancies.
- Regional sensory or motor disturbance.
- Overreaction during examination.
