Walking with multiple sclerosis typically looks slower, stiffer, and less fluid than a healthy gait. The specific pattern varies from person to person depending on which parts of the nervous system are affected, but the most common visible signs include shorter steps, a wider stance, stiff or dragging legs, and a noticeable slowing of pace. Between 70 and 75% of people with MS experience gait problems as the disease progresses.
The Most Visible Changes
The hallmark of MS gait is reduced speed and shorter stride length. People with MS also spend more time with both feet on the ground simultaneously, a pattern called double support. This creates a cautious, shuffling quality to walking that’s often the first thing an observer notices. The overall impression is of someone who looks unsteady or is walking carefully on a slippery surface, even on flat, dry ground.
At the joint level, several things happen that change how walking looks. The hip doesn’t extend as far back during each step, which shortens the stride. The knee doesn’t bend enough when the leg swings forward, making the leg appear stiff. And the ankle doesn’t flex properly at two critical moments: when the foot first hits the ground and when it pushes off for the next step. Together, these restrictions produce a walk that looks rigid and effortful.
When the hip, knee, and ankle all lose range of motion, the pelvis often compensates. The hip may “hike” upward on one side to help clear the foot from the ground, creating a visible tilt or rocking motion in the torso. This compensation tends to appear as disability increases and is less common in people with mild MS.
Foot Drop and Toe Dragging
One of the most recognizable features of MS gait is foot drop, where the front of the foot hangs downward because the muscles that lift it are too weak. During normal walking, you pull your toes up before your heel strikes the ground. With foot drop, the foot stays flat or pointed down, so it either slaps the ground or drags along it.
To compensate, people with foot drop often lift their knee unusually high on the affected side, creating what’s called a “steppage” gait. It looks like exaggerated marching. Others swing the leg outward in a half-circle to clear the foot, a pattern called circumduction. Both compensations are visually distinctive and increase the energy it takes to walk, which leads to faster fatigue. Toe dragging also raises the risk of tripping and falling.
Spastic Gait: The Stiff-Legged Walk
Spasticity, or increased muscle tightness, is one of the most common drivers of MS gait changes. When the muscles in the legs are overly tense, the legs resist bending. This produces a stiff, slow walk with very little knee bend. In more severe cases, the legs may cross or scissor during walking because the inner thigh muscles pull the legs together.
People with spasticity-related gait show greater reductions in walking speed and spend even more time in double support than those without spasticity. The legs may look like they’re fighting against themselves with every step, because they essentially are. The brain’s signals to relax certain muscles during specific phases of walking are disrupted, so muscles that should be loose stay contracted.
Wide-Based and Unsteady Walking
When MS damages the cerebellum (the brain region that coordinates movement) or disrupts the sensory nerves that tell your brain where your limbs are in space, the result is an ataxic gait. The most visible feature is a wider step width. People walk with their feet farther apart to create a larger base of support, much like someone walking on a moving boat.
This type of gait looks uncoordinated and unsteady. Steps may be irregular in timing and length, and the person may sway or veer to one side. The loss of position sense in the feet and legs means the brain is getting incomplete information about where the body is, so every step requires more conscious effort and visual attention. Walking on uneven surfaces or in the dark becomes especially difficult.
How Gait Speed Relates to Daily Life
Clinicians measure MS walking ability with a timed 25-foot walk test, and the benchmarks are striking in how closely they map to real-world impact. People who complete the test in under 6 seconds generally manage daily activities independently. A time of 6 to 8 seconds is associated with needing a cane, changing jobs because of MS, and requiring some help with everyday tasks like shopping or housework. At 8 seconds or longer, people typically need a walker and have significant difficulty with daily activities.
These numbers matter because gait changes in MS are often gradual. Someone might not realize how much their walking has slowed until a measurable benchmark puts it in context.
What Helps Improve MS Gait
Several approaches can meaningfully change how someone with MS walks. A prescription medication that improves nerve signal transmission has been shown to increase walking speed by about 25% in clinical trials, with a 20% improvement considered the minimum change that patients notice in daily life.
For foot drop specifically, functional electrical stimulation (FES) devices deliver small pulses to the muscles that lift the foot, timed to activate during each step. In studies, slower walkers using FES walked significantly faster with the device than without it. Ankle-foot orthoses, which are rigid braces that hold the foot at a proper angle, are another option, though research suggests they can actually slow down people who already walk at a relatively fast pace. FES tends to work better for those who need the most help.
Strength training two to three times per week, focusing on the legs, produces modest but real improvements. Studies report gait speed improvements of 9 to 12% on timed walk tests and increases of 27 to 81 meters on six-minute walk tests. The key finding across the research is that programs that successfully build leg strength tend to improve gait, while those that don’t increase strength don’t improve walking either. The most commonly targeted muscles are those controlling knee extension and flexion, hip movement, and ankle push-off, which are precisely the areas most affected by MS.
Balance training also plays a role, particularly for people with the wide-based, unsteady gait pattern driven by sensory loss or cerebellar involvement. The goal is to retrain the body’s balance reflexes and build confidence in movements that feel risky.
