Taylor Percussion Hammer

The Taylor Percussion Hammer, also known as a tomahawk-style reflex hammer, is distinguished by its unique triangular rubber head and solid handle design . The triangular head is not merely aesthetic; it serves a dual diagnostic purpose. The flat, broad edge of the head is ideally suited for eliciting responses from large tendons, such as the patellar tendon during a knee-jerk reflex test. Conversely, the rounded apex or pointed end is designed for more precise strikes on smaller, deeper tendons, like the biceps tendon in the arm, or for direct percussion on muscles to observe their response .

The handle, typically around 8 inches long and made from solid chrome-plated or stainless steel, is engineered for a secure and balanced grip . This design allows the clinician to hold the hammer loosely between their thumb and forefinger, using a pendulum-like motion from the wrist to deliver a consistent and controlled strike. This technique ensures the tap is of appropriate force, enhancing patient comfort while providing an accurate stimulus for assessing the deep tendon reflexes, which are crucial for evaluating the central and peripheral nervous systems .

While its primary function is testing deep tendon reflexes, the Taylor Percussion Hammer is a versatile diagnostic instrument with several other clinical applications. Its design allows it to be used for percussion, a diagnostic tapping technique used to assess the condition of underlying organs. Specifically, the hammer can be used for chest percussion, where tapping on the chest wall helps a healthcare professional evaluate the density of lung tissue and detect abnormalities such as fluid or masses . Similarly, it can be used for abdominal percussion to assess the size and density of organs like the liver and spleen, or to detect the presence of fluid in the abdominal cavity .

Furthermore, the hammer is an essential tool for a complete neurological examination. The pointed end of the handle is frequently used to test superficial cutaneous reflexes, with the most notable being the Babinski sign . To elicit this response, the clinician strokes the lateral aspect of the sole of the foot with the hammer’s pointed end to observe the toe’s reaction, which can indicate upper motor neuron damage . It can also be used to test for other sensory nerve damage by lightly stroking the skin on the arms, legs, and back .

Proper care and maintenance of the Taylor Percussion Hammer are essential for ensuring its longevity, reliable performance, and adherence to clinical hygiene standards. The primary care routine involves regular cleaning after each use. The hammer should be wiped down with a soft, damp cloth to remove any skin oils or debris . For disinfection, especially in a clinical setting, it is important to use appropriate medical-grade disinfectant wipes that are safe for metal and rubber. Harsh chemicals or strong solvents should be avoided, as they can degrade the chrome finish on the handle and cause the rubber head to crack or become brittle over time .

Regular inspection of the instrument is also a key part of its maintenance. Clinicians should periodically check the triangular rubber head for any signs of wear, such as cracks, hardening, or becoming loose from its mounting . The integrity of the rubber is vital for patient comfort and for delivering a consistent strike. Additionally, the handle should be checked for any signs of rust or corrosion, particularly if it is chrome-plated rather than solid stainless steel. When not in use, the hammer should be stored in a dry, clean environment, such as a drawer or a medical bag, to protect it from dust and moisture . Some models are even designed to be disassembled for more thorough cleaning . Avoiding dropping the hammer is also important, as impact can affect its weight balance and overall functionality .
