Background: To our knowledge, this is the first case report of a cervical disc prolapse and foraminal stenosis presenting with dystonic tremor in addition to brachialgia.
Case Description: A 54-year-old, right-handed man presented with a dystonic tremor and aching throughout his right upper limb. Magnetic resonance imaging of the cervical spine revealed a disc osteophyte complex at C5/6 causing C6 foraminal impingement bilaterally in addition to a disc osteophyte complex at C6/C7 causing severe bilateral foraminal narrowing. Electromyography showed neurogenic changes consistent with chronic C6/7 radiculopathy. There was no response to numerous medical treatments for his dystonia or brachialgia. Computed tomography-guided right C6 and C7 root block led to complete but temporary resolution of all symptoms, including the dystonic tremor. Definitive treatment consisting of a C5/6 and C6/7 anterior cervical discectomy and fusion led to a complete, immediate, and continued resolution of his right-sided brachialgia and dystonic tremor.
Conclusions: This case highlights the potential of cervical disc prolapse to present with dystonic tremor with the likely mechanism being secondary to the painful radiculopathy and highlights the potential benefits of surgical decompression with this atypical presentation.

Center for Medical Sciences, Ibaraki Prefectural University of Health Sciences, Japan.
Article Synopsis
- The yips is a coordination issue in athletes, especially baseball players, tied to task-specific dystonia.
- This study focused on two baseball players displaying different yips symptoms, analyzing their throwing motions and muscle activity using advanced technology.
- It identified two types of dystonic movements: one involving excessive elbow flexion due to improper muscle contraction, and another featuring tremors from inconsistent muscle activity, emphasizing the need for personalized analysis in understanding and addressing yips symptoms.

Tremor is defined as an oscillatory and rhythmical movement. By contrast, dystonia is defined by sustained or intermittent abnormal postures, repetitive movements, or both. Tremor and dystonia often coexist in the same individual.

Spasmodic dysphonia (SD) is now generally considered to be a task-specific focal dystonia. For the first time, we wanted to explore the relationship between SD and dystonia from a combined neurological and phoniatric perspective. For this, we studied 115 patients with non-psychogenic SD by a combined neurological and phoniatric evaluation.

Article Synopsis
- Tremor is a common movement disorder with various causes, and surface electromyography (SEMG) is an effective tool for diagnosing different tremor syndromes.
- A study of 97 patients at a movement disorder clinic revealed that essential tremor was the most prevalent syndrome, with distinct electrophysiologic patterns observed across different types of tremors.
- The results indicate that SEMG can help distinguish between tremor-ataxia syndrome and essential tremor, which can be challenging to differentiate in clinical practice.
