  • STUDY: Intermittent Exercise Helps Multiple Sclerosis Patients

    I've long promoted doing exercises in "pulses" to manage fatigue and weakness. And now we have a study that backs me up! Be sure to read about the woman who was able to walk astonishingly better with regular training. - Dave

    Intermittent Exercise Helps Multiple Sclerosis Patients

    Jim Kling

    June 7, 2010 (San Antonio, Texas) Patients with multiple sclerosis (MS) are able to exercise longer when they take intermittent rest breaks, according to a new study presented here at the Consortium of Multiple Sclerosis Centers 24th Annual Conference and the Third Joint Meeting of Americas Committee for Treatment and Research in Multiple Sclerosis.

    The approach could allow patients to get more benefit from exercise and physical therapy, researchers say.

    Fatigue is a common symptom of MS and frequently limits a patient's ability to exercise. Herb Karpatkin, DSc, MPT, a physical therapist, MS specialist, and professor at the Hunter College Program in Physical Therapy in Brooklyn, New York, and colleagues set out to determine if patients reported different levels of fatigue when they engaged in intermittent instead of continuous exercise. They enrolled 30 ambulatory patients in a study with a repeated-measures, crossover, within-subject design. Participants had Expanded Disability Status Scale scores between 2.0 and 6.5. They were asked to perform 6 minutes of continuous or intermittent walking.

    A visual analog scale of fatigue was used to measure fatigue. When patients walked for 6 minutes continuously, self-rating of fatigue went from a mean of 43.53 points to 68.73 points an increase of 25.20 points. During intermittent walking, the mean fatigue score went from 48.03 to 57.20 an increase of 9.17 points. Disease severity, duration, and the mood of the participant had no effect on the change in score.

    The intermittent approach was suggested by his patients, Dr. Karpatkin told Medscape Neurology & Neurosurgery.

    Intermittent exercise seems to have the same physical benefit as continuous exercise. A comparison hasn't been done in MS patients, but comparison studies of intermittent and continuous exercise have shown the 2 forms of exercise to be equivalent in chronic fatigue syndrome, diabetes, obesity, chronic obstructive pulmonary disease, and fibromyalgia, Dr. Karpatkin said.

    Exercise does take longer, but success is generally its own reward, he noted. "There was 1 patient who couldn't walk more than 3 or 4 minutes on a treadmill; after a few sessions, she could do 20 or 25 minutes. That's a very powerful thing for her," Dr. Karpatkin said.

    "It bodes well for us in how we prescribe exercise programs," Susan Bennett, PT, EdD, NCS, physical therapist and clinical associate professor at the University of Buffalo, New York, who attended the session, told Medscape Neurology & Neurosurgery. Still, the results are preliminary. "More research is needed," Dr. Bennett added.

    The study did not receive commercial support. Dr. Karpatkin and Dr. Bennett have disclosed no relevant financial relationships.

    I can definitely attest to that too.

    I think I learned to ride my trike in small steps. First I rode around my apartment complex, then in an empty parking lot, then on the sidewalk where I live. Every other day I went further.

    This way my body got use to the exercise.

    Now doing 3 miles is nothing. Five miles is next to nothing. In all my rides I stop intermittently for traffic lights, which I purposely try not to catch on the green sometimes just to give myself a physical and mental break.

      Definitely very true! I started with 5 minutes at a time on the elliptical. Now I am up to 25.

      I have also learned to keep my pace steady and slower, it gives me the same workout but less wobbly knee when I hope off.

      Thanks for sharing the article Dave!
