NCT02488031

Brief Summary

The purpose of this research study is to investigate how the brain and motor behavior changes both in individuals with spinocerebellar ataxia and healthy individuals, and to assess whether a therapeutic intervention reduces levels of uncoordinated movement and improves motor function in spinocerebellar ataxia (SCA).

Outcome Measures

Primary Outcomes (1)

  • Change in the Location of the Movement Endpoint Relative to the Target in the Motor Task

    Assessment of the subject's ability to stay on target during the motor task. The task is a goal-directed movement that aims to match a spatial target in a specific time(time target).

    Change from Baseline to 1 month

Secondary Outcomes (3)

  • International Cooperative Ataxia Rating Scale(ICARS) Assessment

    Change from Baseline to 1 month

  • Change in Motor Unit Discharge Rate Variability

    Change from Baseline to 1 month

  • Change in Blood-oxygen-level-dependent(BOLD) Activity of Motor Cortex

    Change from Baseline to 1 month

Study Arms (2)

Error-reduction

EXPERIMENTAL

The participants in the error-reduction group will participate in a 4-week home-based training intervention during the month between their pre- and post-test visits. During pre- and post- training visits, Cooperative Ataxia Rating Scale (ICARS) and the Scale for the Assessment and Rating of Ataxia (SARA), Purdue Pegboard, Brief Test of Attention, 6-minute Walk, Hand Grip Dynamometer, Physical Performance Function, Digit Span, SARA, Montreal Cognitive Assessment, Beck Depression Inventory 2nd Ed, Stroop and biomechanical gait analysis tests will be administered. Also biomechanical assessments of dysmetria and neurophysiological assessment of brain activity will be conducted to evaluate the impact of the training on SCA individuals.

Best Medical Management

EXPERIMENTAL

The participants in the best medical management group will undergo identical testing sessions (two visits one month apart) as those in the error-reducing group but will not receive the 4-week error reducing intervention. They will be administered the International Cooperative Ataxia Rating Scale (ICARS) and the Scale for the Assessment and Rating of Ataxia (SARA) assessments and the following tests: Purdue Pegboard, Brief Test of Attention, 6-minute Walk, Hand Grip Dynamometer, Physical Performance Function, Digit Span, SARA, Montreal Cognitive Assessment, Beck Depression Inventory 2nd Ed, Stroop and biomechanical gait. Biomechanical assessments of dysmetria and neurophysiological assessment of brain activity will be conducted at both visits.

Interventions

Error-reductionBEHAVIORAL

During this time participants will use a novel, custom designed computer interface to perform goal-directed movements with each leg in a 3D virtual environment designed to emphasize accurate movements. Leg movement will be detected using the LeapMotion sensor and we will quantify time endpoint errors by comparing the timing of the foot trajectory and the required time to target. The error-reduction intervention will be a 4-week home-based program. Each participant will train 4 days a week for approximately 1 hours per day. Within a week, the task difficulty will increase by changing the presentation of the targets to be more unpredictable and by increasing movement speed.

Error-reduction

The ICARS is an assessment of the ataxia severity. The ICARS score is the total sum of the sub scores on specific movements and ranges from 0 to 100, with a score of 100 being indicative of the most severely affected outcome.

Best Medical ManagementError-reduction

The SARA is an assessment of the ataxia severity. The SARA score is the total sum of the sub scores on specific movements and ranges from 0 to 100, with a score of 100 being indicative of the most severely affected outcome.

Also known as: SARA

This is a 21 question self-report inventory for measuring severity of depression.

StroopBEHAVIORAL

This test measures selective attention and cognitive flexibility through reading aloud of color names or color of the print.

Purdue PegboardBEHAVIORAL

This test consists of a series of timed hand coordination and dexterity tasks.

6-minute WalkBEHAVIORAL

This test consists on a timed 6-minute walk test to evaluate how much distance is covered.

Best Medical ManagementError-reduction

This tests measures hand grip strength.

Best Medical ManagementError-reduction

This test is used to assess cognitive abilities.

Best Medical ManagementError-reduction

This test consists of a series of physical activities used to evaluate speed, coordination, and ease of movement.

Best Medical ManagementError-reduction

Dysmetria will be assessed using a custom-made goal-directed movement protocol where participant perform unloaded limb movement tasks and attempt to reach a space-time target. During these task muscle activity is monitored using Electromyography (EMG) recording.

Best Medical ManagementError-reduction

Neurophysiology will be assessed by monitoring brain activity using Task-based fMRI and motor unit pool activity using a specialized EMG system.

Best Medical ManagementError-reduction

Participants will wear APDM's wireless sensors on the hands, legs, trunk and forehead and walk overground a distance of 7 m for 2 minutes. APDM quantifies 80 common biomechanical outcomes of gait (e.g. stride length variability).
