NCT07281313

Brief Summary

The goal of this clinical trial is to evaluate the effects of a high-intensity exercise program on recovery in individuals with post-stroke aphasia. The high-intensity exercise program has been specifically designed for individuals with post-stroke aphasia and includes an interval training full-body workout, which can increase cardiovascular fitness, improve muscle strength and motor performance, and maximize cognitive and language gains. The main question this study aims to answer is: • Does participation in a high-intensity exercise program lead to changes in physical health, language, cognitive, motor recovery, psychological and/or psychosocial domains? Participants will be randomly assigned to either a high-intensity exercise program (target intervention) or a low-intensity exercise program (control intervention) delivered over 12-weeks in a group setting. Outcome measures will be collected once immediately after the intervention period and once during the following 12-week maintenance period to capture short- and long-term effects of the exercise program.

Outcome Measures

Primary Outcomes (1)

  • Change on the Western Aphasia Battery (WAB) - Aphasia Quotient

    The Aphasia Quotient from the Western Aphasia Battery (a standardized language test) measures overall severity of language impairment in aphasia and ranges from 0 to 100, with lower scores indicative of more severe aphasia.

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

Secondary Outcomes (11)

  • Change on the WAB subtest scores

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

  • Change on the Curtiss-Yamada Comprehensive Language Evaluation - Revised (CYCLE-R)

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

  • Changes on Category and Letter Verbal Fluency tasks

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

  • Change on the Philadelphia Naming Test (PNT)

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

  • Changes on the California Cognitive Assessment Battery (CCAB)

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

  • +6 more secondary outcomes

Other Outcomes (12)

  • Changes on the Narrative Discourse Sample

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

  • Changes on the Functional Gait Assessment (FGA)

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

  • Change in Center for Epidemiological Studies Depression Scale (CES-D)

    (T1) Baseline: at the start of the study; (T2) Pre-treatment: 1 week prior to the start of the intervention; (T3) Post-treatment: the week immediately following the intervention; (T4) Follow-up: 3 months after the conclusion of the intervention.

Study Arms (2)

High-intensity physical exercise

EXPERIMENTAL

The participants will take part in a high-intensity Aphasia Physical EXercise (APEX) intervention designed specifically for individuals with chronic post-stroke aphasia for 12 weeks.

Behavioral: High-intensity physical exercise

Low-intensity physical exercise

ACTIVE COMPARATOR

The participants will participate in a low-intensity non-aerobic exercise program for 12 weeks.

Behavioral: Low-intensity physical exercise

Interventions

We have developed a new exercise program specifically designed for individuals with post-stroke aphasia, Aphasia Physical EXercise (APEX), to provide a safe, stroke- and aphasia-friendly physical exercise intervention to achieve optimal physical fitness and cognitive/language gains. This intervention, based on published research and clinical practice recommendations, is a high-intensity interval training full-body workout optimized to accommodate the range of motor abilities and general deconditioning observed in stroke survivors.

High-intensity physical exercise

As an active control intervention, a low-intensity non-aerobic exercise program was selected that mirrors more closely the standard-of-care physical therapy currently provided to stroke patients. This control intervention will offer the same level of participant involvement and type of interaction, but without the intensity element, i.e., it will not incorporate the cardiovascular and the strengthening components.

Low-intensity physical exercise
