Neuromuscular electrical stimulation cycling exercise for persons with advanced multiple sclerosis

Area of Science:

• Neurology
• Rehabilitation Medicine
• Exercise Physiology

Background:

• Multiple sclerosis (MS) can lead to significant mobility impairments.
• Advanced MS often limits exercise options, necessitating adapted therapeutic approaches.

Purpose of the Study:

• To assess the feasibility of a modified neuromuscular electrical stimulation (NMES) cycling program for individuals with advanced MS.
• To evaluate the safety and efficacy of NMES cycling in this population.

Main Methods:

• Eight women with secondary progressive MS participated in an 18-session NMES cycling program.
• A fixed pedaling cadence was used, with gradually increasing stimulation intensity.
• Outcomes included tolerated stimulation intensity, thigh circumference, power output, cardiorespiratory response, and perceived benefits.

Main Results:

• Seven participants (Expanded Disability Status Scale 6.5-8.5) completed the program.
• Higher stimulation intensities were tolerated compared to previous studies.
• Participants reported improvements in transfer ability, leg circulation, spasticity, and strength.

Conclusions:

• Modified NMES cycling is a feasible intervention for advanced MS.
• This approach allows for greater muscle stimulation and exercise intensity.
• Individuals with preserved sensation and muscle paralysis/paresis may benefit from appropriately adjusted NMES exercise.
