Overview
Physical examination of patients with tremor varies depending on the cause of tremor.
Physical Examination
Physical examination of patients with tremor varies depending on the cause of tremor.
Appearance of the Patient
- Patients with tremor may present with variable appearance depending on the cause of tremor. It is important to observe for gait, apathy, resting tremor, tremor with voluntary movement, posture, facial masking, sweating when the patient walks in and during history taking.
Vital Signs
- Temperature is usually normal in common causes of tremor.
- Hyperthermia may be present in hyperthyroidism.
- Tachycardia with regular pulse may be found in hyperthyroidism, stress, anxiety
- Tachypnea may be found in stress, anxiety
- Blood pressure with usually normal.
Skin
- Skin examination of patients with tremor is usually normal.
HEENT
- HEENT examination of patients with tremor depends on the cause.
- Look for eye changes characteristic of hyperthyroidism[1].
- Eye movement should be assessed for cerebellar disorders and Parkinson's disease could have double vision due to convergence insufficiency[2].
- Action tremor in patients under forty should be examined for Wilson's disease eye changes, Kayser–Fleischer ring in the cornea.
- Assess for nystagmus if cause of tremor is sudden in onset, associated with new onset headache, vertigo, gait changes. possiblke cause could be a stroke.
- Decreased blinking in Parkinson's disease.
Neck
- Neck examination of patients with tremor is usually normal.
- Hyperthyroidism may have neck swelling, thyromegaly / thyroid nodules[2].
Lungs
- Pulmonary examination of patients with tremor is usually normal.
Heart
- Cardiovascular examination of patients with tremor is usually normal.
Abdomen
- Abdominal examination of patients with tremor is usually normal.
Back
- Back examination of patients with tremor is usually normal.
Genitourinary
- Genitourinary examination of patients with tremor is usually normal.
Neuromuscular
- Patients are usually oriented to persons, place, and time. Detailed neuromuscular examination of patients with tremor should include:
- Parkinson's disease
- Muscle rigidity: Cogwheel rigidity
- Bradykinesia: Slow movement, occurs in Parkinsons disease.
- Abnormal gait: Rombergs test
- Unilateral/bilateral tremor:Frequency, amplitude, pattern, distribution.
- Dysdiadochokinesia (palm tapping test)
- Postural reflexes impaired.
- Cerebellar Tremor:
- Alcohol induced tremor:
- Finger-to-nose test / Dysmetria
Extremities
- Hands should be pronated and resting on the lap to induce resting tremor, it is important to be patient as tremors may take up to thirty seconds to appear. Repositioning hand with little finger down and thumb up can induce Parkinsonian tremor and Holmes tremor.
- Parkinson's disease
- Shortening of stride length
- Appendicular bradykinesia
