Abstract		The various clinical entities of neuromuscular trauma and other lesions leading to pain and limited movement in the shoulder are described. Localised disturbances are most often due to involvement of individual nerves, very rarely due to brachial plexus or radicular involvement and only exceptionally due to spinal cord disease. Focally manifested pain and paresis may occur in generalised lesions such as primary muscle diseases (myositis). Neuromuscular lesions as a rule do not only cause pain, but also additional symptoms and signs. Electrophysiological diagnosis may be used to support a clinical diagnosis of neuromuscular involvement, which can also be more precisely defined. Electrophysiological testing is not, however, a good method to generally rule out neuromus- cular involvement in patients complaining of pain syndromes. Concentric needle electromyography (EMG) is the method of choice to distinguish befween normal, myopathic, and denervated-reinnervated muscle (by analysis of the spontaneous activity, the motor unit potentials and the interference pattern). The tests measuring conduction in motor and sensory fibres of peripheral nerves may distinguish between axonal and demyelinating nerve lesions. In the shoulder girdle area, however, only M-waves can be registered, whereas all other parameters of conduction can only be collected from the long nerves (of the upper extremity), which applies in diagnostics of more widespread trauma or disease. After recent injury a definitive statement on the extent of denervation by EMG can only be expected after approximately three weeks. After the process of reinnervation has been documented by control EMG further follow up can be entirely clinical.
