Patella Hammer

 A Patella Hammer (or Reflex Hammer) is a fundamental neurological diagnostic tool used to test deep tendon reflexes. Its weighted, rubber-tipped head allows clinicians to deliver a controlled, brisk tap to specific tendons, eliciting involuntary muscle contractions that assess the integrity of sensory and motor nerve pathways. As a core component of the neurological exam, it aids in diagnosing conditions ranging from peripheral neuropathies to spinal cord injuries. Its simple, durable design and ease of use make it an indispensable instrument for neurologists, primary care physicians, and any clinician performing a comprehensive physical examination.
