rTMS Improves Functions in Spinocerebellar Ataxia

October 16, 2023 updated by: Sen-yung Liu, Changhua Christian Hospital

Repetitive Transcranial Magnetic Stimulation Improves Functional Performance in Spinocerebellar Ataxia

Spinocerebellar ataxia (SCA) is a group of inherited brain disorders. SCA often result in poor limb coordination. This study aims to discover the effects of repeated transcranial magnetic stimulation (rTMS) on balance & gait in SCA. The hypothesis of this study is that rTMS might improve SCA limb functional performance.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

rTMS has been shown that improves walking speed and balance performance, however, the optimal treatment protocols have not been approved. Past studies used different frequencies 1 Hz, 5 Hz and 10 Hz to improve functional performance. The results might be affected by the types of SCA. In this study, we will focus on the SCA type 3 to assess the effects on high frequency (10 Hz) of rTMS intervention.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes of International Cooperative Ataxia Rating Scale
Time Frame: Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
International Cooperative Ataxia Rating Scale (ICARS): quantify the level of impairment as a result of ataxia as related to hereditary ataxias. Disorders rated as subscales within the ICARS are: Postural and gait disturbances, Limb Ataxia, Dysarthria, and Oculomotor disorders.It translates the symptomatology of cerebellar ataxia into a scoring system out of 100.
Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Changes of SARA
Time Frame: Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Scale for the Assessment and Rating of Ataxia (SARA): a tool for assessing ataxia. It has eight categories with accumulative score ranging from 0 (no ataxia) to 40 (most severe ataxia).
Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Changes of Berg Balance Scale
Time Frame: Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Berg Balance Scale (BBS): a widely used assessment to determine a person's balance abilities. The test contains 14 simple tasks, scoring ranges from 0 to 56. The lower your score, the more at risk you are for losing your balance. The entire process takes about 20 minutes to complete.
Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Changes of Timed up and go
Time Frame: Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Timed up and go (TUG): Patients wear their regular footwear and can use a walking aid, if needed. Begin by having the patient sit back in a standard arm chair and identify a line 3 meters, or 10 feet away, on the floor.
Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Changes of Center of pressure trajectory
Time Frame: Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Center of pressure (COP): he trajectory of the COP, commonly known as a stabilogram, during static balance is frequently used to measure postural control. When standing still on a force platform, the COP is thought to be an indicator of the motor mechanisms involved in maintaining balance with opened-eyes or closed-eyes. Two trials for each condition were performed within 5 minutes.
Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Changes of Kinematic of Gait
Time Frame: Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
The joint angles of hip, knee, ankle are collected during walking in a 10 meters walkway.
Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
Changes of Electromyography of Gait
Time Frame: Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),
A wireless surface Electromyography (EMG) is used to collect lower extremities muscle activation signals during walking in a walkway.
Baseline (T0), 6 days after first rTMS intervention (T1), 12 days after first rTMS intervention (T2),

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Concentration of Neurofilament
Time Frame: Baseline (T0), 12 days after first rTMS intervention (T2)
neurofilament proteins is the biomarkers of axonal damage in diseases affecting the central nervous system
Baseline (T0), 12 days after first rTMS intervention (T2)
Changes of Mini-mental state examination
Time Frame: Baseline (T0)
The mini-mental state examination (MMSE) is a 30-point questionnaire that is used extensively in clinical and research settings to measure cognitive impairment. A score of 25 or higher is classed as normal. If the score is below 24, the result is usually considered to be abnormal, indicating possible cognitive impairment. In this study, it is used to rule out subjects who might have dementia.
