The positive test for the Hoffman's reflex shows a flexion of which structure?

The Hoffman's reflex is a neurological test that is used to assess the integrity of the corticospinal tract. When performing this test, the examiner flicks the distal phalanx of the middle or index finger. A positive response is indicated by the flexion of the thumb or index finger that was flicked. This response suggests potential upper motor neuron lesions or disturbances in neurological function.

In the context of the question, the flexion of the thumb or finger that was flicked is the key indicator of a positive result for the Hoffman's reflex. This reflects a neurological response that may reveal underlying conditions affecting the central nervous system, particularly pathways involved in motor control.

Understanding this reflex and its significance in clinical practice is essential for physical therapists as it provides insight into neurological function and helps guide further assessment and intervention.
