ALS and Motor Neurone Disease

The goal is not recovery and we will not imply otherwise. It is maintaining function at each stage, preventing avoidable complications, and staying ahead of decline with equipment and adaptation.

Overly intensive exercise can cause fatigue that costs more function than it gains. Moderate, carefully dosed activity maintains strength in muscles not yet affected without exhausting those that are.

Respiratory muscle weakness determines survival and quality of life more than limb weakness does, and it develops without obvious breathlessness at first. Early signs include disturbed sleep, morning headaches and daytime sleepiness.

Regular respiratory function monitoring, breath stacking and cough assist, and timely referral for non-invasive ventilation are central. Non-invasive ventilation prolongs survival: in the single randomised trial, median survival was 48 days longer overall and 205 days longer in people whose speech and swallowing muscles were no more than moderately affected, while people with severe bulbar weakness gained no survival benefit 2. Quality of life was also better, although that evidence is of low quality 2.

Swallowing assessment is instrumental rather than observational, because aspiration is often silent. Texture modification, safe swallowing technique and timely discussion of feeding tube options are all part of the plan.

Voice banking is offered early, while speech is still clear, so that a synthesised voice later can be the person's own. Communication aids are introduced before they are strictly needed, because learning them is harder later.

Wheelchairs, hoists, environmental controls and home adaptations take time to obtain. Ordering them at the point they become necessary means weeks or months without them.

Anticipatory provision is uncomfortable to discuss and it is the single most practical thing rehabilitation does in this condition.

Aggressive resistance training does not build muscle where the motor neurone supplying it is failing, and excessive fatigue can worsen function temporarily. Moderate activity maintains what is there without exhausting it.

The programme is therefore built around conserving energy for what matters to the person, maintaining range, and preventing the complications of reduced movement.

Equipment, communication methods and home adaptations are arranged before they are needed, because the pace of change frequently outruns the time it takes to obtain them.

This includes conversations most services postpone — breathing support, feeding, and what the person wants as the condition progresses. Having them early means they happen while the person can lead them.

The evidence is limited. A Cochrane review found only two small trials, with 43 people in total: moderate exercise was followed by better scores on a functional rating scale after three months, with no adverse effects reported, but the trials were too small to show how much exercise helps or whether it can harm 3.

A 2025 meta-analysis of 12 randomised trials with 430 people found improvements in overall function and walking distance, but no effect on fatigue or lung capacity, and cautioned that the trials were few, varied and at risk of bias 4. That supports moderate, supervised activity adjusted as the disease changes, rather than either rest or training to exhaustion.
