Pioneering work done by orthodontists Brendan Stack and Anthony Sims, first published in 2008, provided an opening for the notion of compressive neuropathy of cranial nerves as a precursor to spasmodic torticollis and other movement disorders (Sims & Stack 2008). (mskneurology.com)
What had previously been unknown, however, was how compressive neuropathy of the trigeminal nerve's branches, especially the auriculotemporal nerve, could induce movement disordes as seen in Tourette's syndrome, and even myoclonic and spasmodic nerve disorders such as spasmodic torticollis / cervical dystonia, or generalized dystonia.

Background This study examines the clinical accuracy of movement disorder specialists in distinguishing tremor dominant Parkinson's disease (TDPD) from other tremulous movement disorders by the use of standardised patient videos. (bmj.com)
Patients and methods Two movement disorder specialists were asked to distinguish TDPD from patients with atypical tremor and dystonic tremor, who had no evidence of presynaptic dopaminergic deficit (subjects without evidence of dopaminergic deficit (SWEDDs)) according to 123 I-N-ω-fluoro-propyl- 2β-carbomethoxy-3β-(4-iodophenyl) nortropane ([ 123 I] FP-CIT) single photon emission computed tomography (SPECT), by 'blinded' video analysis in 38 patients. (bmj.com)
The diagnostic distinction of TDPD from dystonic tremor was reduced by the presence of dystonic features in treated and untreated PD patients. (bmj.com)
Conclusion Clinical distinction of TDPD from atypical tremor, monosymptomatic rest tremor and dystonic tremor can be difficult due to the presence of parkinsonian features in tremulous SWEDD patients. (bmj.com)
In this study, the clinical features of patients with tremor and parkinsonism were assessed by two blinded movement disorder specialists (DGG and AJL). (bmj.com)

BACKGROUND: Early spasticity and dystonia identification in cerebral palsy is critical for guiding diagnostic workup and prompting targeted treatment early when it is most efficacious. (bvsalud.org)
However, differentiating spasticity from dystonia is difficult in young children with cerebral palsy. (bvsalud.org)
