This document provides general rules and guidelines for performing a sensory examination, including: - Examining each sensory system from distal to proximal parts of the body and comparing both sides - It defines different sensory systems like touch, pain, temperature and provides tests to assess each one like pin prick for pain and cotton wool for crude touch - Other tests described are for tactile localization, discrimination, pressure sense, vibration sense and stereognosis - Tests for visual fields include confrontation and perimetry tests - Hearing tests covered are watch test, Rinne test, Weber test and audiometry

1. Sensory Revision

2. General rules for Sensory examination
Explain
Close eyes
Move systemically:
From distal to proximal why?
All around why?
Compare the two sides why?

7. Tactlie localization
Two marker test
Tactile discrimination
Weber compass test
Pressure sense
Test for pressure sense
Vibration sense
Tunning fork
Stereognosis
Test for stereognosis using
familiar object
Proprioception
Test for propioception

8. Examination of visual field
I- Confrontation test:
Crude method
Doctor and patient confronting 60cm away from
each other.
Each closes opposite eyes.
They fix their eyes.
Use white object why?

9. II- Perimetry
To examine right eye ask the patient to hold it
with his right hand and place it on his right
cheek and stabilize his right eye on the mirror.
His left eye is closed.
The visual field is plotted on perimetry chart.

10. Light Reflex
Stimulus: Applying light to the pupil
Affrent: Optic nerve
Efferent : Occulomotor nerve
Response: Direct and consensual
pupilloconstriction

12. Near response
(Accommodation reflex)

13. Hearing tests
1. Test for diagnosis of deafness
 Watch test
1. Test for diagnosis the type of deafness
1. Rinne test
2. Weber test
2. Test for diagnosis type and degree of
deafness
 Audiometery
4. Test for localization of sound
