Dejerine Percussion Hammer w/needle 21cm

Clinical Application

Designed for neurologic examination, this percussion hammer provides controlled taps to elicit deep tendon and superficial reflexes (eg, patellar, Achilles, biceps) while an integrated needle permits immediate pin‑prick testing of cutaneous sensation. It is intended for use in neurology clinics, preoperative assessments, inpatient bedside exams, EMG/nerve conduction labs, and routine physicals where both reflex and small‑fiber sensory evaluation are required.

Design & Configuration

The Dejerine pattern balances a focused percussion head for repeatable reflex elicitation with a dedicated needle point for sensory assessment in the same instrument. The 21 cm overall length provides good reach and control during bedside exams while remaining compact for transport and storage. A deliberately weighted head and an ergonomically shaped handle help clinicians deliver clear, reproducible taps with minimal wrist strain; the needle is positioned for immediate use without requiring a separate instrument, streamlining the neurologic exam workflow.
