Parsonage Turner Syndrome

Summarized by Plex Health
Last Updated: 09 May 2022

Parsonage-Turner syndrome is uncommon neurological disorder defined by fast onset of extreme pain in the shoulder and arm. Affected people may recover without treatment, indicating that strength returns to the affected muscles and pain disappears. PTS can be extensively identified as a form of peripheral neuropathy or disorder of the outer nervous system, which encompasses any disorder that largely impacts the nerves outside the central nervous system. Pain may also influence the neck and the arm and hand on the same side as the affected shoulder. Again, it is vital to keep in mind that PTS is a highly variable disorder and one person's specific instance might not look like another person's experience. Additionally, recurrent episodes might include the same outer nerves that were originally affected, completely various peripheral nerves, or a mix of the different and same outer nerves. The strength, duration and location of pain can vary significantly from a single person to another. Pain can potentially be distressing and incapacitating. At some point, affected individuals go into a period where the continual pain reduces and there may be no pain when the affected shoulder and/or arm are not being used. The seriousness of muscular tissue weakness can vary greatly, ranging from mild weak point that might be barely visible to, in uncommon cases, practically total paralysis of the affected muscles. In individuals with PTS, muscle mass weakness results from damages to the nerves that serve the muscle mass in the shoulders and arms. When the shoulder's tendons are pressed or caught throughout shoulder movements, secondary impingement is unpleasant problem that occurs. Subluxation refers to partial misplacement of the shoulder joint. Affected individuals may additionally go to risk of developing contractures, in which abnormal reducing of tendons or muscles results in deformity or rigidness of an affected joint. Contracture of the shoulder, called glue capsulitis, can lead to pain and restriction of the normal series of movement of the joint. Sometimes, nerves outside of the brachial plexus may be entailed such as the nerves of the lumbosacral plexus, the phrenic nerve, or the recurrent laryngeal nerve. The phrenic nerve sends signals between the brain and the diaphragm, which is the muscle mass that divides the lungs from the abdomen. Participation of the phrenic nerve can cause a significant shortness of breath. Involvement of the recurrent laryngeal nerve can result in weak point and partial paralysis of the singing cables and, consequently, hoarseness and soft speech. In very rare cases, other or facial cranial nerves might be affected. Since nerve damages in PTS can impact capillary additional symptoms might develop including affected skin, specifically on the hands, becoming reddened, purplish or discovered. Excessive sweating might occur or affected individuals might feel extraordinarily cold in the affected areas. Some individuals might recover full stamina and useful degrees of the shoulder or affected areas. Current research studies indicate that this can take more than 2 years in some people, while other people will experience residual, persistent pain and issues such as impaired movement of the shoulder and/or affected joints.
