Treatment of muscle weakness in neuromuscular disorders

Introduction: Weakness is one of the predominant clinical manifestations of neuromuscular disorders (NMDs), which strongly influences daily life, prognosis, and outcome of affected patients. One of the major therapeutic goals in NMD-patients is to completely resolve muscle weakness. Various treatment options are available and include physical therapy, electrotherapy, diet, drugs, avoidance or withdrawal of muscle-toxic and weakness-inducing agents, detoxification, stem-cell-therapy, plasma-exchange, respiratory therapy, or surgery. Most accessible to treatment is weakness from immune-mediated neuropathies, immune-mediated transmission-disorders, and idiopathic immune myopathies.Areas covered: This manuscript aims to summarize and discuss recent findings and future perspectives concerning the treatment of muscle weakness in NMDs. Data were obtained by a literature search in databases such as PubMed and Current-Contents.Expert commentary: Weakness is most easily treatable in acquired NMDs and in hereditary myopathies and neuropathies beneficial treatment options are also available. Research needs to be encouraged and intensified to further expand the spectrum of treatment options for weakness.
