Neurology 2 Part 3
Assessing Motor System Muscle Strength Tone – Tension pressure when the muscle is at rest Spasticity – Increase muscle tone Rigidity – Resistance to passive stretch
Flaccidity – Decreased muscle tone Atrophy – Wasting away of muscle Hypotonia – Lose of tone or strength Atonia – No tone or strength
Hypertonia – Increased tone or strength Gait – Manner / style of walking Ataxia – Failure of muscle coordination, irregular voluntary muscle action Akinesia – Abnormal absence of movement Bradykinesia – Slow movement
Have the patient walk across the room under observation. Next ask the patient to walk heel to toe across the room, Then on their toes only, finally on their heels only.
Romberg – Stand feet together arms at side – Eyes open – Eyes closed 20-30 seconds – Slight sway is normal
Assessing Reflexes Grading Scale 0 = No response + = hypoactive ++ = Normal +++ = More active ++++ = Hyperactive
Deep Tendon Reflexes Biceps 1.Thumb on the biceps tendon 2.Strike your thumb with hammer 3.Compare with other arm
Deep Tendon Reflexes Triceps 1.Strike the triceps tendon directly with the hammer while holding the patient's arm with your other hand. 2.Repeat and compare to the other arm.
Deep Tendon Reflexes Patellar
Deep Tendon Reflexes Achilles
Superficial Reflexes (protective reflexes) Corneal Reflex – Test using a clean cotton wisp, lightly touch the outer corner of each eye on the sclera – Normal: (+) elicits a blink – Abnormal: (-) no blink Eye protection Lubrication
Superficial Reflexes (protective reflexes) Gag reflex – Test: gently touch posterior pharynx with cotton applicator – Normal: (+) elevation of the uvula (gag) – Abnormal: (-) No gag NPO
Superficial Reflexes (protective reflexes) Plantar Reflex – Test: stroke the lateral side of the foot with tongue blade – Normal: (- Babinski) toe flexion (curl) – Abnormal: (+ Babinski) toe tanning
