Research on treatment efficacy with dry needling is scarce. The pronator teres is also involved in patterns of spasticity observed in people who had suffered a stroke. AIN syndrome is increasingly thought to be neuritis and it often resolves spontaneously following prolonged observation. Views Cite Permissions Share Abstract Background Entrapment of the median nerve at the pronator teres muscle can contribute to symptoms in the forearm and wrist. In addition, the two syndromes may occur simultaneously, meaning that. The two syndromes are therefore often confused. Pronator Syndrome leads to symptoms similar to those of carpal tunnel syndrome, as the same nerve is involved, but is much less common. PS is a controversial diagnosis and is typically treated nonsurgically. Pronator syndrome is compression of the median nerve about the elbow and/or upper forearm. Pronator Syndrome: Median nerve compression at the elbow and in the proximal. Typically, the findings of electrodiagnostic studies are normal in patients with PS and abnormal in those with AIN syndrome. Carpal tunnel syndrome, a disorder of the median nerve at the wrist. The sites of anatomic compression are essentially the same for both disorders. AIN syndrome is a pure motor palsy of any or all of the muscles innervated by that nerve: the flexor pollicis longus, the flexor digitorum profundus of the index and middle fingers, and the pronator quadratus. Pronator Syndrome leads to symptoms similar to those of carpal. PS is characterized by vague volar forearm pain, with median nerve paresthesias and minimal motor findings. PRONATOR SYNDROME (PS) Pronator syndrome commonly refers to compression of the median nerve as it passes between the 2 heads of the pronator teres muscle or under the proximal edge of the proximal FDS arch. Pronator syndrome is compression of the median nerve about the elbow and/or upper forearm. Dysfunction of the median nerve at the elbow or proximal forearm can characterize two distinct clinical entities: pronator syndrome (PS) or anterior interosseous nerve (AIN) syndrome. PTS develops from compression of the median nerve by the pronator teres muscle, and is sometimes referred to as pronator syndrome.
