Does the patient have neurological problem? : 1. Does the patient have neurological problem? Yes/no Or is it a medical condition simulating paraplegia? Fracture dislocation of pelvis/ Polyarthritis of joints of limbs Or is it a case of Gullain Barre Syndrome Or is it Hysteria or malingering If Yes what is the nature of the deficit? Paraplegia/quadriplegia/ cerebral diplegia/cerbral paraplegia 15 2. What is the mode of onset of paraplegia? : 2. What is the mode of onset of paraplegia? Acute Transverse myelitis, Traumatic paraplegia, Anterior spinal artery syndrome Sub acute: Pott’s paraplegia, Spinal epidural abscess, Spinal cord tumors Chronic Familial spastic paraplegia, Amyotrophic lateral sclerosis, Cranio-vertebral junctional anomalies 16 3. What are the subjective sensory symptoms? : 3. What are the subjective sensory symptoms? Radicular (root) pain or Girdle pain Unilateral or bilateral sharp shooting pain of dermatome distribution Exacerbated by coughing, sneezing or valsalva Vertebral pain: An aching pain confined to a point of spine accompanied by point tenderness Neoplastic or inflammatory dural lesion likely Funicular pain Deep seated ill defined dull ache distant from the affected cord level Common with intra-medullary lesion 17 4. What are the objective sensory deficits? : 4. What are the objective sensory deficits? These may be in the form of Segmental hyper-aesthesia Hypesthesia (decreased touch sensation) Hypoalgesia (decreased pain sensation) Loss of all modalities below a level Loss of position and vibration sense Dissociated sensory loss Suspended segmental loss of pain and temperature Loss of pain & temperature below a particular level 18 5. What are the motor deficits? : 5. What are the motor deficits? Is there any muscle wasting? Is there a disuse atrophy? Is there a distal muscle wasting? Small muscle wasting in syringomyelia? Is there a proximal muscle wasting? What is the tone of the muscles? What is the distribution of motor weakness? Is there any abnormal movements? Is there any loss of co-ordination? 19 6. What are the changes in superficial reflexes? : 6. What are the changes in superficial reflexes? Abdominal reflexes of all 4 quadrants are absent. Cremasteric reflexes absent bilaterally. Plantars are extensor bilaterally - D7 lesion Abdominal reflexes of upper quadrants are present. Lower quadrants are absent. Beever’s sign is positive. Plantar reflexes are extensor bilaterally - D10 lesion Abdominal reflexes of all four quadrants are present. Both cremasteric reflexes are absent. Plantar reflexes are extensor bilaterally. - L1 lesion 20 7. What are the changes in the deep reflexes? : 7. What are the changes in the deep reflexes? Loss of Deep tendon reflexes at segmental level with exaggerated DTR below the level indicate level of lesion Biceps reflex – C5 Supinator reflex – C5 Inversion of supinator – C5 C6 Triceps reflex – C7 Knee reflex –L2 L3 Ankle reflex – L5 S1 21 8. Is it an LMN/UMN lesion or a combination? : 8. Is it an LMN/UMN lesion or a combination? LMN signs alone would indicate the possibility of Anterior horn cell lesion (Spinal muscular atrophy) Nerve root disease ( Radiculopathy) Peripheral nerve lesion ( Peripheral neuritis) Myoneural junction abnormality (Myasthenia) Primary Muscle disease (Myopathies) LMN signs of a segmental distribution indicates an appropriate level of lesion Bilateral UMN findings below that level indicates a transection of corticospinal tracts on either sides Both LMN and UMN signs at the same level suggests the possibility of motor neuron disease 22 9. What is the segmental level of lesion? : 9. What is the segmental level of lesion? It is derived from the information gathered through collection of the data as above Sensory segmental level by root/radicular /girdle pain segmental hyperaesthesia Loss of sensations as per dermatomes Motor segmental level Superficial reflex level Deep tendon reflex level Bladder function level 23 10. Are there other features of the level? : 10. Are there other features of the level? Upper Cervical Cord QP and weakness of diaphragm Lesion of C5-C6 Loss of power and reflex at biceps Lesion of C7 segment Triceps, wrist extensors and fingers Lesion of C8-T1 segments Finger and wrist flexion, Horners Lesions of mid thoracic region?

Radicular pains common early Vertibral pain is common Funicular pain – less common UMN signs present and early LMN signs are unusual segmental Parasthesia ascending progression Sphincter involvement is late Trophic changes are uncommon Radicular pain is unusual Vertibral pain is also unusual Funicular pains may occur UMN signs are present but late LMN signs are prominent and diffuse Paraesthesia-descending progression Sphincter involvement is early Trophic changes are common 31 18. Is it a conus/cauda lesion? : 18. Is it a conus/cauda lesion?
