Parkinsonian syndromes and spinocerebellar ataxia belong to a wider group family of neurodegenerative disorders. Their increasing incidence highlights the importance of correct diagnostics and therapy. In this context, conduction studies and needle electromyography can help in differential diagnosis. Neurophysiological examination may also provide information on the discussed contribution of peripheral neuropathy to etiology of gait disorder and falls, symptoms that are difficult to treat and significantly decrease the quality of life in Parkinsonian syndromes and spinocerebellar ataxias. Disadvantage of this method is lower specificity; therefore it is necessary to correlate the findings with the clinical neurological state.
