Tinel is a term that refers to a medical diagnostic test used to assess nerve injury or irritation in the body. It is named after the French neurologist Jules Tinel, who first described this technique in the early 20th century.
The Tinel sign or Tinel test involves the application of light to moderate pressure over a specific area of a nerve pathway, typically in the limbs, to determine the presence of abnormal sensations or symptoms. The examiner gently taps or strokes the area in question, often using a reflex hammer or their fingertips, and observes the patient's response.
A positive Tinel sign is characterized by the reproduction or exacerbation of specific symptoms, such as tingling, pins and needles sensation, numbness, or pain, radiating along the path of the nerve being tested. This can indicate nerve compression, entrapment, or irritation, often associated with conditions like carpal tunnel syndrome, cubital tunnel syndrome, or peripheral neuropathies.
The Tinel test is commonly performed in clinical settings by healthcare professionals, including neurologists, orthopedic specialists, and physiotherapists. It is a non-invasive and cost-effective method used to aid in the diagnosis and evaluation of nerve-related conditions.
It is important to note that while a positive Tinel sign can provide valuable clinical insights, it is not a definitive diagnostic tool and should be used in conjunction with other assessments and investigations to confirm a nerve injury or pathology.
