Sudden shoulder pain followed by muscle weakness?
Parsonage–Turner Syndrome (PTS) is an uncommon neurological condition that affects peripheral nerves, particularly those supplying the shoulder and upper limb.
Clinical Features
- Sudden, severe shoulder or upper-arm pain.
- Muscle weakness developing after the onset of pain.
- Muscle wasting due to denervation.
- Scapular winging in cases involving the long thoracic nerve.
- Difficulty lifting the arm or performing specific hand movements.
Which Nerves Can Be Affected?
Parsonage–Turner Syndrome may involve different nerves, including the suprascapular, long thoracic, axillary, and anterior interosseous nerves. The pattern of involvement varies between patients and does not necessarily affect the entire brachial plexus.
Role of EMG and NCS
Electromyography (EMG) and Nerve Conduction Studies (NCS) help identify the distribution and severity of nerve injury, detect denervation, and assess evidence of reinnervation during recovery. These investigations also help differentiate the condition from other neurological disorders, including cervical radiculopathy and peripheral nerve lesions.
