Amyotrophic lateral sclerosis (ALS) is a disease of the motor neurons, the nerve cells that carry signals from the brain and spinal cord to the muscles. As those signals fade, muscles weaken and waste. It often starts subtly: a hand that cannot manage buttons, a foot that catches on the ground, speech that slurs when tired. There is currently no cure, and the disease progresses, though the speed varies a great deal from person to person.
This page is educational. ALS care is team care, neurologist, nurses, speech and occupational therapy, respiratory support, dietitians, social work, and family. Physiotherapy is one piece of that team, and its role is worth understanding because it is focused on the practical, day-to-day side of living with the disease.
What physiotherapy actually does in ALS
Movement, dosed carefully. The older fear was that exercise might harm weakened muscles. The research picture today is more balanced: structured, moderate therapeutic exercise appears safe for most people with ALS and may slow functional decline. A systematic review of clinical trials found that people in therapeutic exercise programs declined more slowly on the standard ALS functional rating scale than control groups over six months. The key words are moderate and supervised, the goal is maintaining function and cardiovascular fitness, never training to exhaustion.
Stretching and positioning. As some muscles weaken and others stiffen, joints can lose range. Regular stretching, positioning advice, and splints or supports where appropriate help manage stiffness and discomfort.
Mobility and equipment, timed right. Canes, walkers, ankle braces, wheelchairs, introduced at the right moment, these preserve independence rather than take it away. A physiotherapist’s job includes assessing transfers, home setup, and fall risk as things change, and adjusting the plan before a crisis forces the issue.
Breathing support. As respiratory muscles weaken, breathing exercises and positioning, coordinated with the medical team, become part of care.
Support for caregivers. Teaching family members safe ways to assist with transfers and movement protects everyone’s back and shoulders, and it is a bigger part of good care than most people expect.
The through-line: anticipate, do not react
ALS care works best a half-step ahead, equipment arranged before it is urgently needed, the home rearranged while changes are still easy, energy conservation strategies (planning the day around the hours you feel strongest, sitting for tasks, delegating the heavy work) in place early. Energy is a real budget in ALS, and spending it on what matters to you is a legitimate treatment goal.
A note on honesty
Physiotherapy does not stop ALS, and any provider who suggests otherwise should be questioned. What it can do is help a person stay mobile longer, stay safer, stay more comfortable, and keep participating in their own life. For many families, that is not a small thing.
