Remote aerobic walking exercise training feasible for improving cognitive processing speed in persons with multiple sclerosis

Promising results support development of large-scale randomized controlled trial of remote aerobic exercise training in individuals with MS-related cognitive impairment

Remote aerobic walking exercise training feasible for improving cognitive processing speed in persons with multiple sclerosis
2023-05-04
(Press-News.org) East Hanover, NJ. May 3, 2023 – Results of a pilot study funded by Kessler Foundation showed that remote aerobic walking exercise training is a feasible and highly promising method for improving cognitive processing speed impairment in fully ambulatory persons with multiple sclerosis (MS). The findings of this single-blind randomized control trial support the design of a randomized, controlled trial in large sample of persons with MS

The study, titled "Feasibility of Remotely Delivered and Supported Aerobic Walking Exercise Training for Cognitive Processing Speed Impairment in Fully Ambulatory Persons with Multiple Sclerosis," (doi: 10.1016/j.msard.2023.104709) was published online by Multiple Sclerosis and Related Disorders on April 07, 2023. The authors are Brian M. Sandroff, PhD, Carly L.A. Wender, PhD, Erica Weber, PhD, and Grace Wells, BS, of Kessler Foundation, and Robert W. Motl, PhD, of the University of Illinois Chicago.

The research team followed a group of 25 fully ambulatory persons with MS who were prescreened for deficits in cognitive processing speed; 19 completed the study as prescribed. The researchers employed the Symbol Digit Modalities Test (SDMT), a widely used neuropsychological test for assessing information processing speed in individuals with MS, and the California Verbal Learning Test (CVLT-II) as a widely used test of verbal learning and memory. Evaluations were conducted at baseline and after 16 weeks.

Participants were randomly assigned to 16 weeks of either remotely delivered and supported aerobic walking exercise training (intervention condition), or remotely delivered and supported stretching and range-of-motion activities (control condition). Participants were provided with wearable fitness trackers and weekly video consultations with an exercise specialist to ensure proper technique, safety, and adherence to the prescribed exercise regimen.

The results of the study were promising. Participants who were randomly assigned into the intervention condition demonstrated strong improvements in their SDMT scores after the 16-week study period relative to participants who were randomly assigned into the stretching condition, indicating that the remotely delivered aerobic walking exercise training had a positive impact on their cognitive processing speed. Additionally, the study showed that the participants had high adherence rates to the exercise program, with an average of 80% of the prescribed sessions being completed.

These findings are particularly significant because cognitive processing speed impairment is a common symptom of MS, affecting up to 70% of patients. Impairment is associated with reduced quality of life, increased unemployment, and decreased social functioning. With limited effective treatments available, this study is promising for individuals with this disabling symptom.

The remote delivery and support of the aerobic walking exercise training program also has major implications for the accessibility and convenience of care for individuals with MS. Many patients face barriers to attending in-person exercise programs, such as transportation issues or financial constraints. This study demonstrates that remotely delivered exercise programs can be just as effective as traditional in-person interventions, providing a more inclusive solution for persons with MS.

The researchers are optimistic about the potential applications of their findings. "Our study shows that remote aerobic walking exercise training is not only feasible but also might be efficacious for treating cognitive processing speed impairment in persons with MS," said lead author Dr. Sandroff, senior research scientist in the Center for Neuropsychology and Neuroscience Research. "We anticipate that these findings will encourage the development of more accessible, convenient, and broad-scale exercise interventions, ultimately leading to improved quality of life for those affected by this challenging disease."

Offering genetic testing at the point of care may increase uptake

2023-05-04
Genetic testing for hereditary cancers, such as breast, colon, pancreatic, and ovarian cancer, helps at-risk individuals understand their familial risk for these diseases and make informed decisions about next steps in care. But fewer than 20 percent of at-risk patients utilize this testing, and even fewer engage in genetic counseling after referral, often due to clinical workflow challenges or barriers to care. Amid national efforts to increase access to genetic testing, a new study led by a Boston University School of Public Health researcher has identified a streamlined approach in clinical settings that may help advance ...

Early life abuse may be linked to greater risk of adult premature death

2023-05-04
Physical and sexual abuse in childhood and adolescence could be associated with a greater risk of adult premature death (before age 70), finds research published by The BMJ today. This study extends and refines the existing evidence in this area, and highlights the importance of providing trauma informed care for those who have experienced child abuse, say the researchers. Early life abuse is a global public health issue because it substantially contributes to child death and a range of long term consequences during adulthood. However, the association of childhood or adolescent abuse with total and cause specific premature death during adulthood ...

New study finds no increased risk of menstrual changes after COVID-19 vaccination

2023-05-04
A Swedish study of nearly 3 million women published by The BMJ today finds no evidence of an increased risk of menstrual changes after covid-19 vaccination. Weak and inconsistent associations were found between covid-19 vaccination and contact with healthcare for postmenopausal bleeding and were even less consistent for menstrual disturbance and premenstrual bleeding. These findings do not provide any substantial support for a causal association between covid-19 vaccination and diagnoses related to ...

Deep sleep may mitigate Alzheimer’s memory loss, Berkeley research shows

Deep sleep may mitigate Alzheimer’s memory loss, Berkeley research shows
2023-05-04
A deep slumber might help buffer against memory loss for older adults facing a heightened burden of Alzheimer’s disease, new research from the University of California, Berkeley, suggests. Deep sleep, also known as non-REM slow-wave sleep, can act as a “cognitive reserve factor” that may increase resilience against a protein in the brain called beta-amyloid that is linked to memory loss caused by dementia. Disrupted sleep has previously been associated with faster accumulation of beta-amyloid protein in the brain. However, the new ...

New guidance: antibiotics should be halted upon closure of incisions

2023-05-04
ARLINGTON, Va. (May 4, 2023) — Antibiotics administered before and during surgery should be discontinued immediately after a patient’s incision is closed, according to updated recommendations for preventing surgical site infections. Experts found no evidence that continuing antibiotics after a patient’s incision has been closed, even if it has drains, prevents surgical site infections. Continuing antibiotics does increase the patient’s risk of C. difficile infection, which causes severe diarrhea, and ...

Red flags indicate risk for early-onset colorectal cancer

2023-05-04
Researchers at Washington University School of Medicine in St. Louis have identified four important signs and symptoms that signal an elevated risk of early-onset colorectal cancer. These red flags may be key to earlier detection and diagnosis of early-onset colorectal cancer among younger adults. The number of young adults with colorectal cancer has nearly doubled in recent years. Studying de-identified health insurance data on more than 5,000 patients with early-onset colorectal cancer — cancer that occurs before a person turns 50 — the researchers found that in the period between ...
