Trial Summary

What is the purpose of this trial?

The purpose of this study is to see if 6 months of home-based walking will improve memory, and brain structure and function, compared to health education in older adults that have chronic kidney disease and mild cognitive impairment.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you have a major psychiatric disorder or unstable clinical depression, medication adjustments within 3 months of enrollment may affect eligibility.

What data supports the effectiveness of the treatment Walking Exercise for Mild Cognitive Impairment?

Research shows that exercise can significantly improve cognitive function in people with mild cognitive impairment. Studies have found that various forms of exercise, including walking, can enhance cognitive abilities and physical function, making it a promising treatment option.12345

Is walking exercise safe for people with mild cognitive impairment?

Research shows that home-based exercise programs, including walking, are generally safe for people with mild cognitive impairment. Studies found no major adverse events, and participants were able to complete the exercises successfully.46789

How is home-based walking exercise different from other treatments for mild cognitive impairment?

Home-based walking exercise is unique because it is a low-cost, low-technology treatment that can be done at home, making it accessible and easy to incorporate into daily life. Unlike other treatments that may require special equipment or settings, walking is simple and has been shown to improve cognition and mobility in older adults.48101112

Eligibility Criteria

This trial is for English-speaking adults aged 55 or older with stage 3-4 chronic kidney disease and mild cognitive impairment, but no major head trauma, dementia, severe physical limitations, uncontrolled heart conditions, high blood pressure, or psychiatric disorders requiring medical therapy. Participants must be able to undergo an MRI and not be in a supervised exercise program.

Inclusion Criteria

You have mild problems with memory and thinking, scoring between 18 and 26 on a memory and thinking test called the MOCA.
You are able to have a magnetic resonance imaging (MRI) scan.
My kidney function is moderately to severely reduced.

Exclusion Criteria

You have an unexpected illness or disability that would make it difficult for you to do memory tests or exercise.
You have a condition or device that makes it unsafe for you to have an MRI scan, such as a pacemaker, metal fragments in your body, or a history of claustrophobia.
I was diagnosed with depression or had a change in my depression medication in the last 3 months.

Treatment Details

Interventions

  • Attention control (Other)
  • Home-based walking exercise (Behavioral Intervention)
Trial OverviewThe study is testing if a 6-month home-based walking exercise can improve memory and brain health compared to receiving health education. It targets older adults with chronic kidney disease who also have mild cognitive issues.
Participant Groups
2Treatment groups
Experimental Treatment
Placebo Group
Group I: Home-based walking exerciseExperimental Treatment1 Intervention
A 6-month partially supervised walking exercise training using a tapered approach. Participants begin with exercising (walking) in person, on-site one time per week and 3 times per week at home for a minimum exercise dosage of 30 minutes of accumulated exercise per session during month 1. During month 2, participants will exercise on-site once every other week and 3-4 times per week at home a minimum exercise dosage of 30 minutes of accumulated exercise per session. During months 2-6, participants will exercise at home 4 times per week for a minimum exercise dosage of 30 minutes of accumulated exercise per session and they will receive a phone call every two weeks to help coach and address any problems. Participants will receive a Fitbit fitness tracker that will be used to deliver their personalized exercise program, exercise monitoring, feedback, and motivational messages.
Group II: Health educationPlacebo Group1 Intervention
The health education group will receive the same amount of contact hours as the intervention group. The attention control group will receive health education and stretching exercises. Participants will be in person, on-site one time per week during month 1 for about 30 minutes. During month 2, participants will attend the health education on-site once every other week for about 30 minutes. During months 2-6 participants will receive a phone call every two weeks to help remind about the health education. Participants will receive a Fitbit fitness tracker that will be used for exercise monitoring.

Findings from Research

Exercise significantly improves global cognitive function in patients with mild cognitive impairment, with a strong effect size (SMD = 0.64) based on a meta-analysis of 21 studies.
In addition to cognitive benefits, exercise also enhances balance (SMD = 0.62) and reduces symptoms of depression (SMD = -0.37), indicating its potential as a comprehensive intervention for this population.

Home-based virtual reality (VR) exercise is safe and feasible for individuals with mild cognitive impairment, with participants completing 99% of the prescribed sessions over 6 weeks without major adverse events.
While most participants enjoyed the VR program and reported physical benefits, no significant changes were observed in physical or cognitive outcomes after the 6-week intervention.

A 12-week SMARTfit dual-task training program for older adults with mild cognitive impairment led to significant improvements in cognitive tests (Trail-Making Test and Stroop Test) and physical performance (Short Physical Performance Battery).
Participants in the program reported a positive training experience, suggesting that community-based interventions like SMARTfit could be beneficial for preserving cognitive and physical function in older adults.
