Introduction
The examination and evaluation of deep tendon reflexes are indicated for a wide variety of conditions that affect the Peripheral Nervous System (PNS), Central Nervous System (CNS), or both. The following is an abbreviated list of the most common neurological signs and symptoms that require further examination and evaluation.
- Head, facial or dorsal neck pain or head, neck or spinal injury.
- Disregard or neglect of a body part or lack of awareness of injury or pain.
- Altered movement patterns (e.g., involuntary, unsteady, or slow movements, tremors or twitching of facial muscles).
- Change in muscle tone (e.g., spasticity or rigidity).
- Change in balance or coordination (e.g., clumsiness) or unsteady or altered gait; especially changes resulting in falls or injury.
- Muscle weakness or wasting.
- Paralysis or paresis.
- Slurred or altered speech patterns or drooling, or difficulty swallowing.
- Paresthesia (e.g., tingling, pricking, burning, and numbness) or change in somatosensation (e.g., altered hot/cold, sharp/dull or light touch sensation).
- Change or alteration in sense of hearing (e.g., hearing loss or buzzing in ears), sight (e.g., blurry vision, diplopia, or visual field changes), smell (e.g., anosmia) or taste.
- Change in behavior, personality or cognition, or difficulty concentrating or thinking, confusion or lethargy; including changes expressed by friends and family members.
