For the patient usually one of the ®rst symptoms of a lesion within the central motor system represents the movement disorder, which is most characteristic during locomotion in patients with spasticity. The clinical examination reveals exaggerated tendon tap re¯exes and increased muscle tone typical of the spastic movement disorder. However, today we know that there exists only a weak relationship between the physical signs obtained during the clinical examination in a passive motor condition and the impaired neuronal mechanisms being in operation during an active movement. By the recording and analysis of electrophysiological and biomechanical parameters during a functional movement such as locomotion, the signi®cance of, for example, impaired re¯ex behaviour or pathophysiology of muscle tone and its contribution to the movement disorder can reliably be assessed. Consequently, an adequate treatment should not be restricted to the cosmetic therapy and correction of an isolated clinical parameter but should be based on the pathophysiology and signi®cance of the mechanisms underlying the disorder of functional movement which impairs the patient. Spinal Cord (2000) 38, 389 ± 393 Keywords: spinal cord injury; spasticity; electrophysiological recordings; treatment Introduction Movement disorders are prominent features of impaired strength of electromyographic (EMG) activation of function of the motor systems and are frequently best antagonistic leg muscles as well as intrinsic and passive re¯ected during gait. -

Noxious stimuli can produce profound alterations in sympathetic pilomotor, sudomotor, and vasomotor activity, as well as disturbances in cardiac rhythm.

Late-Onset Oro-Facial Dyskinesia in Spinocerebellar Ataxia Type 2: a Case Report Floriana Giardina1†, Giuseppe Lanza2,3*† , Francesco Calì3 and Raffaele Ferri3
Giardina et al. BMC Neurology (2020) 20:156 https://doi.org/10.1186/s12883-020-01739-8 CASE REPORT Open Access Late-onset oro-facial dyskinesia in Spinocerebellar Ataxia type 2: a case report Floriana Giardina1†, Giuseppe Lanza2,3*† , Francesco Calì3 and Raffaele Ferri3 Abstract Background: Genetic familiar causes of oro-facial dyskinesia are usually restricted to Huntington’s disease, whereas other causes are often missed or underestimated. Here, we report the case of late-onset oro-facial dyskinesia in an elderly patient with a genetic diagnosis of Spinocerebellar Ataxia type 2 (SCA2). Case presentation: A 75-year-old man complained of progressive balance difficulty since the age of 60 years, associated with involuntary movements of the mouth and tongue over the last 3 months. No exposure to anti- dopaminergic agents, other neuroleptics, antidepressants, or other drugs was reported. Family history was positive for SCA2 (brother and the son of the brother). At rest, involuntary movements of the mouth and tongue were noted; they appeared partially suppressible and became more evident during stress and voluntary movements. Cognitive examination revealed frontal-executive dysfunction, memory impairment, and attention deficit. Brain magnetic resonance imaging (MRI) disclosed signs of posterior periventricular chronic cerebrovascular disease and a marked ponto-cerebellar atrophy, as confirmed by volumetric MRI analysis. A dopamine transporter imaging scan demonstrated a bilaterally reduced putamen and caudate nucleus uptake. Ataxin-2 (ATXN2) gene analysis revealed a 36 cytosine-adenine-guanine (CAG) repeat expansion, confirming the diagnosis of SCA2. Conclusions: SCA2 should be considered among the possible causes of adult-onset oro-facial dyskinesia, especially when the family history suggests an inherited cerebellar disorder. -

Gait impairments are common in patients with chronic supratentorial upper motor neuron lesions, and are a source of great disability. Clinical management aimed at improving the gait pattern in these patients is generally perceived as a challenging task, as many possible abnormalities may interact. Moreover, a multitude of treatment options exist – ranging from assistive devices and muscle stretching to pharmacological and surgical interventions – but evidence is inconclusive for most approaches and there is a lack of clear treatment guidelines. -
