Multiple Sclerosis Patients Show Improved Reactions with Treadmill Exercise

MS and exercise

Several studies have shown that exercise can improve movement in multiple sclerosis (MS), but new research indicates that it specifically may also  improve reaction time, a measurement of cognitive impairment. The study, titled Acute effects of varying intensities of treadmill walking exercise on inhibitory control in persons with multiple sclerosis: A pilot investigation and conducted by researchers at the University of Illinois and the State University of New York, Buffalo, appeared Nov. 10 in the journal Physiology and Behavior.

Treadmill walking could be the best form of exercise for people with MS who are fully ambulatory. However, researchers do not yet know how much walking is needed to have beneficial effects. The investigators of the current study, led by Brian M. Sandroff of the Department of Kinesiology and Community Health, University of Illinois at Urbana-Champaign, wanted to measure levels of walking against improve reaction times and to find out if there’s a correlation between the intensity of a walking exercise and increases in the level of improvement observed.

The study compared the influence of light, moderate, and vigorous treadmill walking on what is known as inhibitory control — a mental ability to react to stimuli. A fourth condition included a period of quiet rest, to compare the effects of no walking whatsoever. All of the 24 study participants undertook each of these four conditions for 20 minutes in a random order and then went through a modified flanker task, or test of reaction time, in which subjects either respond to specific relevant stimuli or ignore irrelevant stimuli. The time it took to respond correctly and appropriately was measured as reaction time.

Each of the three exercise levels improved reaction time in the flanker task when compared to quiet rest, but the different  treadmill speeds did not appear to bring different levels of benefit. In their study, researchers noted, “There were no differences in magnitude of reduction across the three exercise intensities.” They further stated, “The present results support light, moderate, and vigorous intensity treadmill walking as exercise stimuli that might particularly benefit interference control of reaction time. This represents the next step in delineating the optimal exercise stimuli for improving this cognitive function in fully-ambulatory persons with MS, and perhaps is important for informing a subsequent longitudinal exercise training intervention.”

Future studies may focus on comparing other exercises to treadmill running. Ultimately, understanding the best type of exercise and how much is optimal could help physical therapists and physicians in planning and recommending specific exercise programs to people with MS.

    Hola: Quiero contar mi historia con EM.
    Fui diagnosticada en año 1998 sólo con hormigueo en pié derecho, compresión medular.
    Así 5 años con similares síntomas 2 o 3 veces al año, mi vida seguía normal.
    En año 2003 recibo Interferón beta-1a alejó los síntomas, me fui sintiendo cada vez mejor, lo recibí durante 5 años, manejaba vehículos, moto, auto, caminaba hasta más de 6 Kilómetros, nadar en el mar, etc, sin cansancio a 10 años de mi diagnóstico y mas.
    La que era mi dra. porque él primero falleció me niega el Interferón cuando me lo iba a otorgar el Estado, me decía todo el tiempo que no creía en los Interferones.
    A los 3 años comienzo con espasticidad, comenzó lentamente a progresar.
    A mi el Avonex me cayó espectacular hice una vida muy normal sin cansancio, no dolor, sin calores, no tenía nada de nada.
    Les quise contar mi experiencia con el ejercicio.
    Saludos Pina!

      Hi, I want to tell my story with MS.
      I was diagnosed in 1998 with just tingling right foot, spinal cord compression.
      So five years with similar symptoms 2 or 3 times a year, my life was ordinary.
      In 2003 receiving interferon beta-1a away the symptoms, I was feeling better and better, I got it for 5 years, driving vehicles, motorcycle, car, walked up over 6 kilometers, swim in the sea, etc, without fatigue 10 years of my diagnosis and more.
      Which was my dr. because He first denied me died when I Interferon would grant the State, I kept saying he did not believe in the interferons.
      At 3 years beginning with spasticity, slowly he began to progress.
      My Avonex fell dramatically made me a very normal life with no fatigue, no pain, no heat, there was nothing.
      They wanted to tell my experience with exercise.
      Pina Greetings!
