Rehabilitative Trial With Cerebello-Spinal tDCS in Neurodegenerative Ataxia (CStDCSAtaxia)

Rehabilitative Trial With Cerebello-Spinal tDCS for the Treatment of Neurodegenerative Ataxia

Neurodegenerative cerebellar ataxias represent a group of disabling disorders for which we 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, the investigators will evaluate whether a two-weeks' treatment with cerebellar anodal tDCS and spinal cathodal tDCS can improve symptoms in patients with neurodegenerative cerebellar ataxia and can modulate cerebello-motor connectivity, at short and long term.

Detailed Description

Neurodegenerative cerebellar ataxias represent a heterogeneous group of disabling disorders in which progressive ataxia of gait, limb dysmetria, oculomotor deficits, dysarthria and kinetic tremor are the prominent clinical manifestations. Both the hereditary and sporadic forms usually present in young adulthood, and are characterized by atrophy of cerebellar or brainstem structures. Currently, cerebellar ataxia lack effective disease-modifying 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. The present randomized, double-blind, sham-controlled study will investigate whether a two-weeks' treatment with cerebellar anodal tDCS and spinal cathodal tDCS can improve symptoms in patients with neurodegenerative cerebellar ataxia and can modulate cerebello-motor connectivity, at short and long term.

Subjects will be randomized in two groups, one receiving a 10 day (5 days/week for 2 weeks) treatment with anodal cerebellar and cathodal spinal tDCS and the other receiving sham stimulation with identical parameters. After the intervention, patients will be reassessed with a clinical and neurophysiological evaluation at 2 weeks, 1 months and 3 month after treatment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in the International Cooperative Ataxia Rating Scale (ICARS) Score From Baseline
Time Frame: Baseline - 2 weeks
International Cooperative Ataxia Rating Scale (ICARS): semi-quantitative 100-point scale, yielding a total score of 0 (no ataxia) to 100 (most severe ataxia).
Baseline - 2 weeks
Change in the Scale for the Assessment and Rating of Ataxia (SARA) Score From Baseline
Time Frame: Baseline - 2 weeks
Scale for the Assessment and Rating of Ataxia (SARA): 8-item performance based scale, yielding a total score of 0 (no ataxia) to 40 (most severe ataxia).
Baseline - 2 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in the International Cooperative Ataxia Rating Scale (ICARS) Score From Baseline
Time Frame: Baseline - 2 weeks - 1 month - 3 months
International Cooperative Ataxia Rating Scale (ICARS): semi-quantitative 100-point scale, yielding a total score of 0 (no ataxia) to 100 (most severe ataxia).
Baseline - 2 weeks - 1 month - 3 months
Change in the Scale for the Assessment and Rating of Ataxia (SARA) Score From Baseline
Time Frame: Baseline - 2 weeks - 1 month - 3 months
Scale for the Assessment and Rating of Ataxia (SARA): 8-item performance based scale, yielding a total score of 0 (no ataxia) to 40 (most severe ataxia).
Baseline - 2 weeks - 1 month - 3 months
Change in the 9 Hole Peg Test (9HPT) Score From Baseline
Time Frame: Baseline - 2 weeks - 1 month - 3 months
4 timed trials of the 9 hole peg test (9HPT) were performed and averaged (mean values are reported) for each separate hand (dominant and nondominant). The total time to complete the task is recorded for each trial and for each separate hand (dominant and nondominant). Longer times represent greater impairment.
Baseline - 2 weeks - 1 month - 3 months
Change in the 8-Meter Walking Time (8MW) Score From Baseline
Time Frame: Baseline - 2 weeks - 1 month - 3 months
4 timed trials of the 8 meter walking time (8MW) were performed and averaged (mean values are reported). Longer times represent greater impairment.
Baseline - 2 weeks - 1 month - 3 months
Change in Cerebellar Brain Inhibition (CBI) Measurements From Baseline
Time Frame: Baseline - 2 weeks - 1 month - 3 months
Cerebellar brain inhibition (CBI) is expressed as motor evoked potential amplitude (average of 10 recordings). Lower values reflect higher inhibition and thus reduced impairment.
Baseline - 2 weeks - 1 month - 3 months
Change in the Short-Form Health Survey 36 (SF36) Score From Baseline
Time Frame: Baseline - 2 weeks - 1 month - 3 months
The Italian version of the Short-Form Health Survey 36 (SF-36): consists of 36 scaled score, yielding a total score of 0 (more disability) to 100 (less disability).
Baseline - 2 weeks - 1 month - 3 months
