Stroke and cramps: what to know

After stroke, muscles may become tight or activate at the wrong time. This increased tone can make a limb feel stiff, pull a joint into an unusual position, or cause painful spasms. Cramps can also follow overuse during rehabilitation, prolonged sitting, dehydration, medication effects, or changes in minerals and nerve function. The location, duration, triggers, weakness, swelling, and effect on walking help a clinician work out the likely cause.

During a cramp, stop the activity, support the limb, and use the gentle stretch or positioning taught by your rehabilitation team. Keep a record of when cramps occur, what you were doing, and whether the muscle remains tight afterwards. Drink regularly unless fluid restriction has been advised. Do not start supplements, muscle relaxants, or intense stretching without clinical advice. A GP or stroke team can review medicines and refer for targeted rehabilitation if needed.

Call emergency services if cramps occur with sudden new weakness, facial change, speech difficulty, confusion, loss of balance, or new numbness. Seek prompt assessment for a swollen, red, hot, or persistently painful limb, inability to walk, severe weakness, fever, or repeated spasms that prevent sleep or basic activities. These features may point beyond an ordinary muscle cramp.

Ask whether the pattern fits spasticity, a medication effect, dehydration, or another cause; which stretches are suitable; and whether physiotherapy, occupational therapy, or medicine review could help. Mention falls, sleep disruption, and any change in walking.
