Individualized Neuro-Modulation Paired With Cerebellar Therapy (IMPACT)

8 de junio de 2026 actualizado por: Amy J. Bastian, Ph.D., Hugo W. Moser Research Institute at Kennedy Krieger, Inc.
The purpose of this project is to evaluate feasibility and preliminary efficacy of pairing personalized transcranial direct current stimulation (tDCS) with individualized rehabilitation therapy in people with cerebellar damage.

Descripción general del estudio

Descripción detallada

Cerebellar damage causes debilitating ataxia affecting balance, coordination, speech, and cognition. Rehabilitation therapy is the main treatment for ataxia because pharmacological therapeutics are extremely limited. Non-invasive brain stimulation has shown promise in improving motor function and has an excellent safety profile. However, optimal stimulation sites and efficacy when combined with rehabilitation remain unclear.

We hypothesize that three weeks of intensive rehabilitation therapy paired with personalized transcranial direct current stimulation (tDCS) will produce greater functional improvements in people with cerebellar damage compared to therapy with sham stimulation.

This double-blind, randomized, sham-controlled trial will enroll participants with cerebellar damage. We will determine stimulation sites using multimodal neuroimaging and electric field modeling and then check their response to stimulation. If they show MRI response to stimulation and it is well-tolerated, they will be eligible to receive 30 hours of training (one hour, twice daily), with active or sham tDCS during one of the daily sessions Primary outcomes are the Scale for Assessment and Rating of Cerebellar Ataxia (SARA) and Patient-Reported Outcome Measure of Ataxia (PROM-Ataxia), assessed pre-treatment, post-treatment, and at 3- and 6-month follow-ups.

This research addresses a critical gap in treatment options for cerebellar ataxia by testing whether personalized neuromodulation enhances rehabilitation outcomes.

Intervención / Tratamiento
Experimental: Active stimulation combined with therapy.
Once a stimulation site is determined, subjects will receive 20 minutes of active tDCS stimulation daily. Subjects will also receive one hour of therapy, twice daily. Therapy will be individualized to each subject and, will encompass three domains; 1) walking and balance control, 2) hand dexterity and arm control, 3)speech articulation, prosody, and intelligibility. Subjects will complete up to 30 therapy sessions.
Each participant will choose a domain that they would like to focus on. Choices are: 1) walking and balance control, 2) hand dexterity and arm control, or 3) speech articulation, prosody, and intelligibility.

Medida Descripción
Periodo de tiempo
Scale for the Assessment and Rating of Ataxia (SARA)
Periodo de tiempo: Assessed at pre-treatment, post-treatment, and at 3- and 6-month follow-ups.
The SARA is a tool for assessing ataxia. SARA is an 8-item performance based scale, yielding a total score of 0 (no ataxia) to 40 (most severe ataxia). The scores are based on patient performance of: gait, stance, sitting, speech disturbance, finger chase, nose-finger test, fast alternating hand movements, heel-shin slide.
Assessed at pre-treatment, post-treatment, and at 3- and 6-month follow-ups.
Patient-Reported Outcome Measure of Ataxia
Periodo de tiempo: Assessed at pre-treatment, post-treatment, and at 3- and 6-month follow-ups.
The PROM-Ataxia is a self reported questionnaire used by researchers to evaluate the daily impact and progression of cerebellar ataxia directly from the patient's perspective. The questionnaire encompasses 70 total items within 3 main domains: 1) Physical: Gait, manual dexterity, swallowing (dysphagia), and visual/ocular motor control. 2) Activities of Daily Living (ADL): Managing household chores, employment, driving, and self-care. 3)Mental: Mood, anxiety, motivation, and cognitive tasks (e.g., multitasking and comprehension).
Assessed at pre-treatment, post-treatment, and at 3- and 6-month follow-ups.
