MS research update - Gait variability - how someone's way of walking can change with MS - 03 April 2013

Summary

This paper is a review of how the way that someone walks can vary more if they have MS. Factors that can vary include step length and the angle of the hip, knee or ankle. When walking further, other factors, including fatigue, play a part.

Background

Many people with MS have some difficulties with walking. These difficulties may have a significant impact on quality of life for someone who is more severely affected. However, for some people, the changes in their walking are more variable and subtle but may result in more stumbling or tripping than usual.

How this study was carried out

This paper is a review of previously published research on how gait (the way someone walks) varies in people with MS. It aims to draw together all the available data to explain why people with MS, on average, experience more variability in their gait than people who do not have MS.

Walking is a complicated process which involves coordinating several systems:

  • the central nervous system (to send messages from the brain to move the muscles and to monitor and coordinate movement and balance)
  • the many muscles involved in walking and the underlying skeleton (which all need to move in the correct sequence)
  • the cardiovascular system (so that the heart can pump oxygen and nutrients around the circulation to power movement)

All of the time, the brain is monitoring what is happening so that it can refine movements and keep the body upright.

What was found

The researchers divided their analysis into gait variability during a short walk or a longer walk.

Most research had looked at short walks (less than 10 metres/33 feet). It had been found that, over a year, there was quite a large (20%) natural variation in walking ability on the 25 foot walk performance test so this was considered as the background level of variability. If the variation was more than 20% over a year then this represented a significant change in someone's walking. Those with greater disability had more variation in their walking.

Particular aspects of walking that seemed to vary were step length, the time taken for each step and the angle of the hip, knee or ankle. Step width was not affected.

On longer walks (typically six minutes long), other factors came into play towards the end of the walk. In particular, people who used walking sticks or other assistance had much greater variation in step time, length and width in the last two minutes of the test as compared with the first two minutes. The authors suggest that this may be due to changes in stability and increasing fatigue.

What does it mean?

The authors suggest that variations in walking are due to a combination of factors:

  • there may be an increase in background noise in the signal passing down the nerve to the muscle
  • Fatigue (for longer walks)
  • Decreased muscle strength
  • Difficulties with balance and proprioception (the ability to unconsciously know the position of the body, its posture and how it is moving)
  • Spasticity (muscle stiffness)
  • Cognitive difficulties especially lack of attention

Gait variability is associated with falls in the elderly and the same may be true for people with MS. In addition, having a more variable gait will probably use more energy to walk a given distance as it will be necessary to correct the foot if it has been placed poorly. Using more energy is likely to lead to fatigue and fatigue, in turn, leads to increased gait variability which needs even more energy. This gives rise to a vicious cycle where walking further becomes increasingly difficult.

More about walking difficulties

Walking problems vary considerably from one person with MS to another. Common difficulties are:

  • Unsteadiness on walking or turning
  • Slower, shorter steps
  • Less confidence
  • Needing support from walls, furniture, other people or walking aids
  • Tripping and stumbling
  • A heavy feeling in the legs when stepping forward
  • Weakness of the leg when weight is on it
  • Difficulty placing the foot on the ground

The reasons behind difficulties with walking vary widely. They include spasticity (muscle stiffness), spasms and muscle weakness. Sometimes, the causes are less obvious such as numbness, which can make it difficult to feel the floor properly, or sight problems, including double vision.

Being able to walk is central to many activities of every day life so it is important to consult a health professional such as a GP, MS nurse or physiotherapist about any walking difficulties. Treatment will depend on what is causing the underlying problem.
