Overview

A complete physical examination may be suggestive of initial diagnostic clue about an ischemic stroke presenting as decreased motor strength, sensory loss or cranial nerve involvement.[1]It may also help assess degree of neurological deficit, identifcation of cause, localization of site of infarction, selection of patient for appropriate intervention, determination of prognosis and complications and ruling out differential diagnosis.

Physical Examination

A complete physical examination in the patient of ischemic stroke is essential for the following reasons:

  • Assess degree of neurological deficit
  • Identify the cause
  • Locate the site of infarction
  • Selection of patient for appropriate intervention
  • Determine the prognosis and complications
  • Rule out differential diagnosis

Physical assessment may be divided into 1) GPA 2) Systemic examination 3) Neurological examination:

General physical assessment and Systemic Review

Neurological examination

The physical examination findings in ischemic stroke may vary according to the blood vessel involved and site of infarction:

Vessel involved Physical examination
Anterior cerebral artery [2][3]
Middle cerebral artery[7]
  • Most common site of infarction
Posterior cerebral artery[14][15][16][17][16][18]
Vertebrobasilar artery[22] Midbrain
  • Contralateral decreased motor strength
  • Deviation of eye downwards and outwards-ipsilateral 3rd nerve palsy
Medulla
  • Impaired gag reflex
  • Uvula deviated to the opposite side of lesion
  • Ptosis
  • Miosis
  • Enophthalmos
  • Ipsilateral impaired pain, touch and temperature sensation on the upper half of the face
  • Contralateral decreased motor strength and sensory loss
  • Romberg's sign
  • Deviation of tongue to the side of lesion-hypoglossal nerve
  • Contralateral decreased motor strength
  • Contralateral loss of position sense, vibration and two point discrimination
Pons
  • Inability to close eyes
  • Deviation of angle of mouth
  • Facial muscle weakness-Facial ner ve
  • Loss of taste sensation on the anterior two thirds of tongue
  • Affected eye deviation inwardsand down-Abducent nerve
  • Locked-in syndrome[28][29]
Cerebellum

Neurological assessment with standardized scales

The neurological assessment of the patient with ischemic stroke may be done using standardized scoring system to assess patient prognosis and treatment strategy. Two types of scoring systems widely used are:


For more information about Glasgow coma scoring system, click here.

Glasgow coma score

Glasgow coma score helps determine the severity of infarction, extent of damage and prognosis in unconscious or semi conscious patients. The score is determined by adding score in each category with the maximum score of 15 and minimum score of 3.[30][31][32][33][34]

  • Abnormal extension to pain (decerebrate posture)

Interpretation of Glasgow coma scale:

The following interpretation of glasgow coma scale may help determine the prognostic outcome in patients with brain injury:

Mild brain injury

Glasgow coma scale of 13-15

Moderate brain injury

Glasgow coma scale of 9-12

Severe brain injury

Glasgow coma scale of 3-8
