Full Abstract: Chronic overuse of the arm or fingers results in movement disorders. In particular, repetitive motion can result in upper extremity 'dystonias'. These are painless contractions that hinder smooth repetitive movements of the involved digits or limb. As a result, patients present with twisted appendages or unusual posture. This review aims to elucidate these dystonias and separate them from peripheral nerve entrapments, tenosynovitis, epicondylitis, and arthritis. The appropriate diagnosis provides the basis for proper medication, muscle restrengthening and botulinum toxin injections.
