Active clinical trials for "Spinocerebellar Ataxias"

The aim of this study is to evaluate the efficacy and safety of C-Trelin OD Tablet 5mg(Taltirelin Hydrate) in Multicenter, randomized, double-blind, placebo-controlled clinical trial in patients with ataxia induced by spinocerebellar degeneration.

Neurodegenerative cerebellar ataxias represent a group of disabling disorders which currently lack effective therapies. Cerebellar transcranial direct current stimulation (tDCS) is a non-invasive technique, which has been demonstrated to modulate cerebellar excitability and improve symptoms in patients with cerebellar ataxias. In this randomized, double-blind, sham-controlled study followed by an open-label phase, the investigators will evaluate whether a repetition of two-weeks' treatment with cerebellar anodal tDCS and spinal cathodal tDCS, after a three months interval, may further outlast clinical improvement in patients with neurodegenerative cerebellar ataxia and can modulate cerebello-motor connectivity, at short and long term.

Spinocerebellar ataxia 38 (SCA 38) is a very rare autosomal dominant inherited disorder caused by a mutation in ELOV5 gene, specifically expressed in cerebellar Purkinje cells, encoding an enzyme involved in the synthesis of fatty acids. The present study aimed to assess the effect of cerebellar anodal transcranial direct current stimulation (tDCS) administered employing deltoid (CD-tDCS) and spinal (CS-tDCS) cathodal montage. Clinical evaluation was performed at baseline (T0), after 15 sessions of tDCS (T1) and after one month of follow-up (T2).

The study is to examine the effect of functional trunk training on trunk control and upper extremity functions in patients with autosomal recessive ataxia.

The purpose of this study is to investigate the superiority of KPS-0373 to placebo, and evaluate the safety of KPS-0373 in SCD patients.

The purpose of the clinical trial is to study the therapeutic efficacy and safety of Stemchymal® infusions for polyglutamine spinocerebellar ataxia treatment by a randomized, double-blind, placebo-controlled study design. Eligible subjects will receive Stemchymal® through intravenous infusion.

The Cerebellum contains ten percent of the total volume of the brain and receives brain, spinal cord and vestibular sensory input. The organization of vestibular and somato-sensory afferent informations are also reported to be impaired in patients with cerebellum dysfunctions. Ataxia and impaired balance control are common symptoms in individuals with spinocerebellar ataxia (SCA). Previous studies have shown that patient with cerebellar damage are usually agonist and antagonist muscle coordination problem. Past studies also found the regulation of reciprocal Ia inhibition was impaired in patients with spinaocerebellar ataxia. In chronic phase, weakness might be developed due to deconditioned. All deficits mentioned above might lead to a decrease functional ability. Therefore, increasing somato-sensory and vestibular input, normalizing the modulation of recriprocal inhibition, and improve muscle strength might be able to improve the functional abilities of individuals with SCA. Recently, whole body vibration (WBV) has been trained for health groups. Studies showed that WBV training were able to improve muscle strength, balance control, and functional ability. However, there is no evidence showed that whether the whole body vibration training can affect the brain and spinal cord for the regulation of neural circuits. Whether also can affect for maximal voluntary contraction and improve central fatigue. No previous studies that whole body vibration training for SCA. Therefore, the purpose of this research was to investigate the intracortical facilitation and inhibition, reciprocal Ia inhibition, low frequency depression, maximal voluntary contraction, interpolated twitch technique to compare the different between the SCA and health subject. Also to investigate the short term and long term effect of WBV.

Spinocerebellar ataxia (SCA) is a hereditary disorder with movement incoordination. The ataxia performed low intra-cortical facilitation mainly due to the degenerative cerebellum. Noninvasive sensory stimulations such as peripheral electrical stimulation were reported to modulate the excitability of the motor excitability. Neuromuscular electrical stimulation (NMES) was proposed as a neuromodulation tool for the aberrant motor excitability on the SCA. This study aims to investigate the effect of NMES on the motor excitability in the SCA, and the differentiation on the central or peripheral motor excitability changed by the NMES.

In individuals with spino-cerebellar atrophy (SCA), the delayed onset of antagonist muscle firing has been reported to be the cause of hypermetria. Hypermetria is a common deficit in individuals with spino-cerebellar atrophy SCA when they perform ballistic goal-directed movement. Based on the previous studies, ballistic goal-directed movements are controlled by a triphasic pattern of agonistic and antagonistic muscle activation. The origin of the EMG pattern is a central program, whereas the delayed onset of antagonistic muscle firing has been reported to be the cause of hypermetria. To develop a therapy method, the difference in temporal pattern and intensity of supraspinal excitability of agonist and antagonist bursts between healthy adults and individuals with SCA when performing rapid and slow goal-directed movements should be further investigated. Traditional rehabilitations of individuals with cerebellum lesion were limited to improve the functional performance of movement. Since the deficits of the goal-directed movement are at pre-movement programming, only feedforward training will be possible to re-establish an appropriate program. Previous showed that peripheral stimulation resulted in a facilitation of motor cortex. Our group also found that this facilitation in individuals with SCA was similar to the ones without SCA. Therefore, it is possible to adjust the control pattern of supraspinal excitability of agonist and antagonist busts of SCA patient with passively providing electrical stimulation contains normal control pattern of healthy human. The present study sought to investigate the difference in temporal pattern and intensity of supraspinal excitability of agonist and antagonist bursts between healthy adults and individuals with SCA when performing rapid and slow goal-directed movements.

This research study is testing body-worn sensors to measure movement during simple tests of coordination, in order to evaluate the progression and severity of ataxia.
