How does multiple sclerosis contribute to difficulty walking down stairs?

In multiple sclerosis, the immune system attacks the protective covering of nerves, disrupting signals that control balance and muscle strength. As a result, people with MS often experience leg weakness and poor coordination. Research shows that balance problems and altered walking patterns are common in people with MS, making stair descent especially difficult. Going down stairs is more challenging than walking on flat ground because it requires more precise control, which increases the risk of missteps and falls. People with MS often develop different strategies to stay upright. These compensatory movements may include using other muscle groups more heavily or changing how they distribute their body weight in order to avoid falls.
