always confusing ipsilateral Vs contralateral
Posted: 31 Aug 2012, 05:45
It's always confusing (ipsilateral, toward) and (contralateral, away) physical signs in neurologic lesions.
Here's an attempt to collect these signs in one thread:
• Hypoglossal Nerve Palsy: Tongue deviated toward the side of the lesion, except in UMN.
• Vagus Nerve Palsy: Uvula deviates away but the palate droops on the same side.
• In Sensorineural Deafness: Weber lateralizes away from the affected ear.
• Accessory Nerve Palsy: Sternomastoid is weak in turning away from the lesion but you can't shrug the shoulder on the affected side.
• Facial Nerve Palsy: in UMN lesions there's loss of motor function of contralateral (away) lower half of the face.
• Cerebellar lesions: The body sways towards the side of the lesion in Romberg's test.
• Nystagmus (fast component): Ipsilateral in cerebellar lesions but contralateral in vestibular lesions.
• Caloric test: away from the cool water.
• Horizontal Gaze Palsy: Eyes deviates to the contralateral side in frontal cortex lesions and to the ipsilateral in PPRF lesions.
• Jaw jerk: The chin deviates toward the lesion side.
• Abducens nerve palsy: You will have ipsilateral medial strabismus.
• Oculomoter Nerve Palsy: You will have ipsilateral lateral and down strabismus.
• Descending hypothalamics lesion: Always ipsilateral Horner syndrome.
