Study Notes

Neurological Emergency Case Study

Patient Presentation: 52-year-old male, head trauma, drowsy, verbal response only, slurred speech, pupils equal and reactive to light.
Level of Consciousness: Obtunded (likely).
Glasgow Coma Scale (GCS): Score is 7 (eyes open to voice, localized response to pain, inappropriate words).

Suspected Meningitis Case Study

Patient Presentation: 24-year-old student, severe headache, stiff neck, fever, suspected meningitis.
Meningeal Irritation Test: Brudzinski's sign.
Positive Brudzinski's Sign: Flexion of knees and hips when neck is flexed.

Musculoskeletal Injury Case Study

Patient Presentation: Difficulty with shoulder movement following a fall, limited abduction, pain with active range of motion.
Passive ROM: Nurse assists patient in moving the joint.
Possible Condition: Rotator cuff injury (limited abduction but flexion and extension possible).

Stroke Symptoms Case Study

Patient Presentation: Elderly woman, struggles to form coherent sentences, difficulty understanding verbal instructions.
Suspected Conditions: Receptive or expressive aphasia (or global aphasia).
Cranial Nerve for Speech Assessment: Cranial nerve XII (Hypoglossal), also important for speech.

Balance and Coordination Case Study

Patient Presentation: Frequent falls, difficulty maintaining balance, unsteady gait during tandem walk.
Brain Region Impaired: Cerebellum.
Romberg Test: Positive result indicates sensory ataxia.

Pain and Sensory Response Case Study

Patient Presentation: 35-year-old male with diabetes, numbness and tingling in both feet.
Sensory Examination Techniques for Light Touch: Compare sensations bilaterally, start proximally and move distally.
Vibration Sense Test (Tuning Fork): Inability to detect vibration in toes, but detection on shins, suggests peripheral neuropathy.

Motor Function and Reflexes Case Study

Patient Presentation: 28-year-old athlete, weakness in right leg, knee injury.
Reflex for L2-L4 Spinal Segments Assessment: Patellar reflex.
Reflex Grade 0: No reflex response (indicates nerve damage).

Musculoskeletal Posture Case Study

Patient Presentation: Middle-aged teacher, back pain, hunched posture, exaggerated thoracic curvature (kyphosis).
Condition: Kyphosis.
Further Assessment: Measuring spinal flexibility during forward bending.

Neurological Coordination Case Study

Patient Presentation: 62-year-old man, tremors, poor coordination, hand tremors when reaching for objects.
Possible Condition: Intention tremor or Parkinsonian tremor.
