Study Notes
Cranial Nerve Examination and Sensory System Testing
- The patient is unarousable with eyes closed and shows no response to inner need or external stimuli
- The examination includes assessing the patient's alertness and orientation to person, place, time, and situation
- The cranial nerve assessment covers various aspects including olfactory, visual acuity, pupillary reactions, extraocular movements, and sensory and motor functions of the trigeminal and facial nerves
- The examination also involves assessing the vestibulocochlear nerve for hearing and the glossopharyngeal and vagus nerves for voice and swallowing
- Evaluation of the spinal accessory nerve includes testing trapezius and sternocleidomastoid muscle strength
- Assessment of the hypoglossal nerve involves inspecting the tongue for symmetry, movement, and strength
- The sensory system testing includes assessing light touch, pain and temperature sensation, position and vibration sensation, and discriminative sensation
- Prior to conducting sensory system tests, it is important to explain the procedure to the patient and ensure their eyes are closed
- The sensory system testing involves comparing symmetry by testing both sides of the body
- The testing covers various sensations including light touch, pain, temperature, position, vibration, and discriminative sensations
- Coordination of sensory system testing is done in conjunction with motor testing
- The testing includes evaluating the quality of lingual speech sounds and the patient's ability to identify different tastes on each side of the tongue
Neurological Examination Techniques
- Specific steps for testing sensation, including light touch, pain, and temperature, with instructions for mapping areas of deficit
- Areas for specific nerve roots and the corresponding body parts affected
- Techniques for testing muscle stretch reflexes, reflex grading, and reinforcement
- Detailed instructions for testing specific reflexes, including biceps, brachioradialis, triceps, quadriceps, and Achilles reflexes
- The importance of assessing body position, involuntary movements, muscle bulk, muscle tone, and muscle strength during the motor system examination
- Common findings in muscle tone, such as spasticity, rigidity, and flaccidity
- Factors to consider when assessing muscle strength, including paresis, hemiparesis, and paralysis
- The significance of asymmetrical findings in reflex testing
- The use of reinforcement techniques to increase reflex activity
- Instructions for using appropriate reflex hammers and striking techniques during reflex testing
- The different grades of reflexes, ranging from absent to hyperactive with intermittent clonus
- Techniques for testing reflexes in both sitting and supine positions, as well as alternative methods for examining the supine patient
