Ataxia, Cerebellar clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

tDCS Associated With Locomotor Training on Functional Mobility of Cerebellar Ataxia

Start date: November 1, 2018
Phase: N/A
Study type: Interventional

Cerebellar ataxia is a neurologic symptom caused by a damage or a dysfunction in cerebellum and results in loss of coordination, balance and postural control. This impairment could result in a reduction of walking speed, short and irregular steps and difficulty in coordinating between lower limbs. Pharmacological interventions are not able to modify ataxia gait pattern, therefore, new approaches to rehabilitate must be studied. Treadmill locomotor training (TLT) and cerebellar transcranial direct current stimulation (ctDCS) are physical therapy techniques able to module cerebellar afferences and modify positively ataxia gait pattern. However, there is no study involving the association of these two techniques. The purpose of this study is to evaluate the effects of ctDCS associated to TLT on functional mobility in subjects with cerebellar ataxia. A randomized, sham controlled, double blind clinical trial will be performed. The subjects will be randomly allocated into two groups: (i) ctDCS associated with TLT; (ii) ctDCS sham associated with TLT. The TLT will be performed with a speed and step length progression protocol for 25 minutes. The anodal ctDCS (2 mA, 25 minutes) or sham (2mA, 30 seconds) will be applied during TLT. The functional mobility will be the primary outcome and will be evaluated through timed up and go test (TUG). Ataxia' severity, balance and fall risky, will be the secondary outcomes and will be evaluated by the scale for the assessment and rating of ataxia (SARA), balance evaluation system test (miniBest) and TUG, respectively.
