Exercise for Peripheral Neuropathy

(CYCLE-CIPN Trial)

This trial aims to determine if regular cycling exercise can reduce symptoms of peripheral neuropathy (nerve damage) caused by chemotherapy. Participants will engage in supervised cycling sessions twice a week for 12 weeks to assess the practicality and impact on quality of life. The researchers seek individuals with mild peripheral neuropathy who have undergone chemotherapy for stage I to III cancer and are not currently participating in similar exercise programs. As an unphased trial, this study provides a unique opportunity to contribute to understanding how exercise might enhance life quality for those affected by chemotherapy-induced nerve damage.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Research has shown that aerobic exercise, such as cycling, is safe for individuals with peripheral neuropathy. Studies have found that these exercises do not cause serious side effects. For example, cycling is safe for people with diabetes who have nerve damage and can even improve leg function. Participants in various studies, including those with diabetic nerve damage, reported no major problems from aerobic exercise. Stationary cycling is considered a safe and easy exercise option for those with nerve damage from chemotherapy. Overall, exercise is generally well-tolerated and effective for managing symptoms related to chemotherapy-induced nerve damage.¹²³⁴⁵

Researchers are excited about cycling-based aerobic exercise as a treatment for peripheral neuropathy because it offers a non-pharmaceutical approach that could improve nerve function and reduce symptoms without the side effects associated with medications. Unlike standard treatments that often involve pain relievers, antidepressants, or anticonvulsants, this exercise-based method focuses on enhancing blood flow and nerve health naturally. Additionally, aerobic exercise can potentially improve overall physical fitness and quality of life for patients, offering a holistic benefit beyond symptom management.

Research has shown that aerobic exercises, such as cycling, can alleviate symptoms for people with chemotherapy-induced peripheral neuropathy (CIPN). Cycling, in particular, improves blood flow in the legs and helps control blood sugar levels, both of which benefit neuropathy. A review of several studies concluded that exercise effectively reduces the severity of CIPN symptoms. Specifically, one study found that after an 8-week exercise program, participants experienced less pain and a moderate reduction in neuropathy symptoms. This trial will specifically evaluate the effectiveness of a cycling-based aerobic exercise intervention for managing and reducing CIPN symptoms.²³⁶⁷⁸
