it started with ‘dropfoot’

MS foot drop happens when nerve damage in the brain or spinal cord affects the muscles that lift the front of the foot.
The foot then does not clear the ground properly, so the toes may drag or catch while walking.
That can raise the risk of trips and falls, and it often makes the leg feel more tired.
It can be more noticeable on uneven ground, stairs, or when fatigue is already strong.

How to recognise it

One common sign is scuff marks on the front of the shoes.
People may also catch their toes on small objects or uneven surfaces.
To make up for this, some swing the leg out to the side or lift the knee higher than usual.
A heel that lands first, followed by the front of the foot slapping down, is another clue.

Why it happens in MS

Foot drop can happen when nerve signals between the brain and the legs are slowed or blocked.
This affects the muscles that lift the ankle, which are called the dorsiflexors.
It may appear during a relapse, and it often improves with time or steroid treatment.
In other cases, it develops more slowly as MS progresses.

Treatment options

Functional electrical stimulation uses small electrical pulses to help trigger the nerves that lift the foot during a step.
An ankle-foot orthosis, or AFO, is a light brace or splint worn inside the shoe to keep the foot at a right angle. Physiotherapy and exercise can also help, especially stretches and resistance work with bands… these can ease tightness, improve ankle stability, and build strength for walking.

The MS Society and the MS Trust both provide clearer guidance on managing foot drop and its effect on mobility.
