Tinel's sign; Transverse section across the wrist and digits. (The median nerve is the yellow dot near the center. The carpal tunnel is not labeled, but the circular structure surrounding the median nerve is visible.) A photograph conveying Tinel's sign being performed on the left foot to support the diagnosis of morton's neuroma. Specialty
Tinel's sign is performed by lightly tapping the median nerve just proximal to flexor retinaculum to elicit paresthesia. [ 5 ] Durkan's test , carpal compression test , or applying firm pressure to the palm over the nerve for up to 30 seconds to elicit paresthesia.
Tinel's sign and Phalen's tests can be used to assess for CTS. They may be administered by the physical therapist (PT) or occupational therapist (OT). Tinel's sign involves tapping at the volar wrist while Phalen's test involves maintaining maximum wrist flexion for 60 seconds. In both tests, a positive sign is indicated by numbness, tingling ...
Diagnosis is based upon physical examination findings. Patients' pain history and a positive Tinel's sign are the first steps in evaluating the possibility of tarsal tunnel syndrome. X-ray can rule out fracture. MRI can assess for space occupying lesions or other causes of nerve compression. Ultrasound can assess for synovitis or ganglia.
In Autumn 1915, he published his famous article about the distal regeneration sign, then baptised Tinel's sign. [2] [3] In 1916, he published in French an amazing book about the cutaneous nerves distribution of the whole body. Each aesthesiography is a mapping of the hypoaesthetic area induced by the nerve injury. [4]
It is a new variation of Tinel's sign that was proposed by JA Durkan in 1991. [1] Process

Tarsal tunnel syndrome is the most commonly reported nerve entrapment of the ankle. It is analogous to carpal tunnel syndrome in the wrist.It is caused by compression of the tibial nerve underneath the flexor retinaculum of the foot. [1]
