Adverse mechanical tension

Nature 
Adverse mechanical tension (AMT), also known as 'neural tension,' is where the nerves running down to the arm have become contracted and possibly compressed as a result of muscle spasms in the shoulders and elsewhere. AMT is often misdiagnosed as or associated with one of the other occupational overuse disorders. It is largely reversible and can be treated with physiotherapy.
