Neuromuscular Centre the Netherlands
The field of neuromuscular diseases in the Netherlands is characterized by a longstanding tradition of collaboration between seven neuromuscular centres of the university hospitals. This collaboration has been formalised since 1993, when the Dutch Neuromuscular Research Centre (Stichting ISNO) was founded. ISNO has stimulated the focussing of the individual neuromuscular centres upon specific disorders (e.g. on ALS or Guillain-Barré syndrome). ISNO has continued in 2016 as Neuromuscular Centre Netherlands, with the aim to encourage and facilitate research, and to improve treatment of neuromuscular disorders. It forms a platform bringing together Dutch neuromuscular specialists and researchers in a network of excellence. It collaborates especially with the Dutch Neuromuscular Fund (the Prinses Beatrix Spierfonds) and the neuromuscular patients organization (Spierziekten Nederland). The Neuromuscular centre the Netherlands organises a yearly symposium on neuromuscular diseases for neurologists, paediatricians, and physiatrists, aimed at improving knowledge on neuromuscular diseases. Furthermore, the Centre has successfully developed a curriculum for a neuromuscular fellowship for neurologists, which intends to improve neuromuscular knowledge throughout the country.

National registry
The Neuromuscular Centre the Netherlands has developed a national registry for neuromuscular diseases, the Computer Registry of All Myopathies and Polyneuropathies (CRAMP database).1 The Dutch CRAMP database started in 2004, and was the first nationwide registry that did not focus on a specific disorder, in contrast to various registries across the world. It allows registration of a vast number of neuromuscular disorders, including certain neuromuscular features (such as myalgia, cramps, dys- or atrophy of the muscle) in case a classified neuromuscular diagnosis is lacking. One of the incentives was to gather up-to-date nationwide epidemiological data regarding neuromuscular disorders. From 2004 until 2015, over 25,000 individuals with a neuromuscular disorder have beeb registered in CRAMP, of whom 56% were men.2 CRAMP contained 90% of all reimbursed diagnoses in university medical centres in 2010, meaning that the registration coverage is high. This data is important in the daily practice both in the diagnostic process of individuals and in other health care issues like assessment of trial feasibility and planning of care.
Expert centres
The longstanding collaborative effort within the Neuromuscular Centre the Netherlands has stimulated research, and also has led to numerous collaborative papers. 3-14 Another purpose of the Dutch Neuromuscular Centre is the development of expertise centres for several neuromuscular diseases, such as myasthenia gravis, myotonic dystrophy, ALS, facioscapulohumeral muscular dystrophy, inflammatory neuropathies, small fibre neuropathy, mitochondrial myopathies, Pompe disease, and Duchenne muscular dystrophy. This development, acknowledged by the Dutch government, has further stimulated excellent patient care and research, and ultimately resulted in the acknowledgment of all these centres as part of the European Reference Network EURO-NMD, coordinated by the group in Newcastle upon Tyne.
The collaborative effort of the Dutch Neuromuscular centres within the Neuromuscular Centre the Netherlands emphasises the strong benefits of collaboration, resulting in improvement of patient care as well as clinical and preclinical research, and has proven its success over many decades.
