The Neurological Buck Reflex Hammer is a versatile diagnostic instrument used by healthcare professionals to evaluate deep tendon reflex and assess nerve sensitivity. Its multi-functional design combines several tools into a single, compact device, making it a staple for neurologists, GPs, and medical students. The classic Buck design typically measures about 18 cm (7 inches) and includes the following components:
- Dual-Head Percussor: The hammer head features two differently sized rubber mallets. The larger side is used for broad tendons like the patella (knee), while the smaller side allows for more precise tapping on smaller areas.
- Integrated Brush: A small brush is often concealed within the base of the handle. It is removable and used to test cutaneous reflexes and light touch sensation.
- Removable Needle: A sharp pin or needle is typically hidden in the head of the hammer (spinning out from the top) to evaluate pain perception and nerve sensitivity.
- Balanced Handle: Usually made of chrome-plated brass or stainless steel, the handle is ergonomically designed and weighted to provide controlled percussion force with minimal effort.
