Exploring the Feasibility of an Exercise and Noninvasive Brain Stimulation Intervention in Breast Cancer Survivors

7 maggio 2026 aggiornato da: Florida Atlantic University
The purpose of this study is to assess the feasibility of a 4-week intervention combining exercise and transcranial alternating current stimulation (Ex+tACS) in breast cancer survivors who report experiencing cancer-related cognitive impairment. Feasibility will be assessed by measuring participant retention, adherence, satisfaction with the intervention, and safety. The researchers will also examine pre-to-post intervention changes in attention, executive function, working memory, perceived cognitive function, and physical function before, after, and four weeks post intervention completion in the Ex+tACS group compared to a control group who will receive exercise and a placebo tACS condition (CON).

Panoramica dello studio

Descrizione dettagliata

Breast cancer is one of the most common forms of cancer among women in the United States. Although advances in cancer treatments have led to improved survival rates, breast cancer survivors must contend with the negative side effects from the cancer and its treatments. One of the most common and highly distressing treatment side effects is cancer-related cognitive impairment (CRCI), which is characterized by losses in memory, attention, processing speed, and executive function, which make daily tasks such as recalling information, organizing daily routines, concentrating, and multitasking more challenging. Findings from previous studies support aerobic exercise training as an effective strategy for improving cognitive function. In addition, non-invasive brain stimulation (NIBS), a technique in which electrodes are applied to the skin to noninvasively stimulate specific regions of the brain, has also been found to be a safe and effective approach for improving cognitive outcomes. Among various NIBS techniques, transcranial alternating current stimulation (tACS), which delivers current to the brain in an alternating pattern, may be a promising strategy for improving cognitive outcomes. Few studies have explored these approaches in breast cancer survivors, and to our knowledge, the combination of exercise and tACS (Ex+tACS) has not been explored.

This study will assess the feasibility of a 4-week Ex+tACS intervention in breast cancer survivors who report cancer-related cognitive impairment. Researchers will also examine changes in attention, executive function, working memory, perceived cognitive function, and physical function before, after, and four weeks post intervention completion in the Ex+tACS group compared to a control group who will receive exercise and a placebo tACS condition (CON).

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Intervention Arm
The Exercise + transcranial alternating current stimulation (Ex+tACS) group will complete a four-week intervention consisting of 3 days/week of 30 minutes of aerobic exercise on a treadmill at a sustained moderate intensity, immediately followed by 15 min of tACS. During tACS, 6Hz alternating current stimulation will be administered to participants' prefrontal cortex (forehead region) using a tACS while the participant completes the AX Continuous Performance Test (AX-CPT).
The Ex+tACS group will complete a four-week intervention consisting of 3 days/week of 30 minutes of aerobic exercise on a treadmill at a sustained moderate intensity, immediately followed by 15 min of tACS while completing the AX Continuous Performance Test (AX-CPT).
Comparatore fittizio: Control
The Sham Comparator group will complete 30 minutes of aerobic exercise on the treadmill followed by the Sustained Attention-Continuous Performance Task (AX-CPT) with a sham transcranial alternating current stimulation (tACS) condition. The same procedures will be followed regarding the tACS, but stimulation will only last one minute, ramping up and down at the beginning and end of the 15-minute period, simulating the periodic tingling sensation that are reported with tACS.
The Control (CON) group will complete 30 minutes of aerobic exercise on the treadmill followed by the Sustained Attention-Continuous Performance Task (AX-CPT) with a sham tACS condition. After each session, both the EX+tACS and control participants will complete a questionnaire regarding experience with tACS.
