Dejerine Percussion Hammer 20cm.

Clinical Application

Designed for neurologic assessment, this instrument is used to elicit deep tendon reflexes (biceps, triceps, patellar, Achilles) and superficial reflexes during focused neurological and perioperative examinations. It provides a predictable, focal stimulus for reflex grading and serial examinations in outpatient clinics, inpatient wards, pre-operative assessments, and neurology practices.

Design & Configuration

The Dejerine pattern combines a single striking head and a 20 cm length to balance reach and control: the length enables comfortable access to distal lower-extremity reflex sites while remaining compact for pocket or lab-coat carriage. A resilient striking surface concentrates the delivered impulse to a small contact area to produce a clear tendon stretch response, and a solid handle geometry supports a controlled wrist flick technique for reproducible testing.
