Nerve Entrapment & Release Flashcards

Meralgia paresthetica is caused by entrapment of which nerve, and at what location?

Answer: Lateral femoral cutaneous nerve medial to the ASIS under the inguinal ligament

The lateral femoral cutaneous nerve becomes entrapped as it passes under or through the inguinal ligament just medial to the ASIS, causing anterolateral thigh burning and paresthesia.

In ART, the term 'density change' refers to:

Answer: A palpable increase in tissue stiffness indicating adhesion or fibrosis

Density change describes the practitioner's palpation of abnormally firm or adherent tissue at an entrapment interface, guiding precise contact placement.

Which movement sensitizes the upper limb neurodynamic test (ULNT1) targeting the median nerve?

Answer: Cervical contralateral lateral flexion away from the test arm

Adding cervical lateral flexion away from the tested arm increases tension on the median nerve neurodynamic test, confirming neural rather than musculoskeletal origin of symptoms.

A powerlifter develops posterior interosseous nerve palsy after squatting. ART would most likely address which structure first?

Answer: Supinator at the arcade of Frohse

Heavy axial loading can tighten the supinator and its fibrous arch (arcade of Frohse), compressing the posterior interosseous nerve; ART targets adhesions within the supinator.

Which sequence correctly describes the ART nerve-release protocol steps?

Answer: Contact density change → shorten tissue → apply tension through patient active motion → maintain contact until endpoint

The ART nerve protocol shortens the tissue first, applies contact at the density change, then has the patient actively lengthen the tissue to generate relative motion between nerve and surrounding structure.

A patient with tarsal tunnel syndrome has symptoms aggravated by eversion and dorsiflexion. The ART practitioner targets adhesions between the tibial nerve and which structure?

Answer: Flexor hallucis longus tendon within the tarsal tunnel

The tibial nerve travels in close proximity to the flexor hallucis longus tendon within the tarsal tunnel, and adhesions between these structures are a common entrapment cause.

In the ART management of double crush syndrome, treatment priority is given to:

Answer: The proximal entrapment site first to restore axoplasmic flow before releasing the distal site

Treating the proximal compression first restores axoplasmic flow, which improves the nerve's ability to heal and respond to treatment at the more distal entrapment site.
