Etiology of RSD
Published in Hooshang Hooshmand, Chronic Pain, 2018
Cervicogenic RSD in rare cases can cause tremor in the hand and forearm, and in some cases it can be severe enough to cause writer’s cramp and illegible handwriting. This complication is more commonly seen after traumatic adjustment of the cervical spine.
An introduction to occupational health nursing

Greta Thornbory, Susanna Everton
The person regarded as the ‘father of occupational medicine’ is the seventeenth-century Italian Professor of Medicine, Bernardino Ramazzini. He published in Latin De Morbis Artificum Diatriba or Diseases of Tradesmen and Craftsmen.5 This was an exhaustive work outlining the health hazards of chemicals, dust, metals, repetitive or violent motions, odd postures and other disease-causative agents encountered by workers in 52 occupations; these included stone cutters, millers, masons, bricklayers, chemists, metal diggers, potters and glass makers, surgeons and wet nurses as well as learned men. The latter were affected by the more commonly known ‘writer’s cramp’, or as it is known today, repetitive strain injury or work-related upper-limb disorder. Through personal example, Ramazzini demonstrated the importance of talking directly with workers and of visiting workplaces to investigate the working environment in order to improve it. He focused on the need for providing workers with adequate information about health hazards and he suggested practical measures to protect workers from illness and injury.
Movement Disorders

Isolated dystonic writer’s cramp usually appears in middle or late life and does not usually progress to involve other parts of the body. Some individuals learn to write with the opposite arm, but the problem may spread to that side in up to one-third of cases. Drug treatment is disappointing. Botulinum toxin injections, under EMG control, can help many patients.

In 2015, results of a single blind clinical trial that investigated the effects of levodopa and botulinum toxin in 14 patients with SCA3/MJD-related dystonia were reported [34]. In the whole cohort, dystonia improving effects of levodopa were not significant (p = 0.07). There were, however, some patients who had dramatic improvement. In contrast, dystonia scores declined significantly 4 weeks after botulinum toxin injections in the whole group (p = 0.03). However, some patients had important side effects, such as diplopia, ptosis, and dysphagia, even receiving doses within the usual therapeutic range. There is another report of patients with SCA3/MJD-related dystonia treated with botulinum toxin and developing severe dysphagia. This indicates that these patients might indeed be at increased risk of such adverse reactions, likely due to concomitant peripheral nerve involvement [42,43]. Nevertheless, other patients with blepharospasm and writer’s cramp related to SCA3/MJD have been safely treated with low doses of botulinum toxin [35,44].
René Cruchet (1875–1959), beyond encephalitis lethargica
Published in Journal of the History of the Neurosciences, 2022
He asserted he was the first to identify neuralgic torticollis, a defensive attitude, comparing this clinical picture to facial neuralgia. The professional form was due to a repeated movement or position sustained for a long time, as in the case of writer’s cramp. He established a similarity between paralytic torticollis and facial palsy that can result in a spastic residual contraction. Spasmodic torticollis was similar to facial spasms and could “present as spasmodic bradykinesia, an entirely new disease or one that has not attracted notice until now, our description being the first, as validated by the English School” (1920b).
