Stiffness, spasms and spasticity

Status: sourced · Content checked 2026-10-06

Stiffness describes an experience. Spasticity describes a neurological examination finding. Bring the pattern and functional effects to assessment instead of having to choose the label first.

1 · Quick understanding

Spasticity and spasms can limit movement, comfort and daily activities. Weakness and muscle shortening can also contribute to stiffness.

N2

2 · Possible explanations

Use concrete language: resistance when moving, a sudden spasm, a fixed restriction, or difficulty generating movement. Ask the examiner which findings explain each problem.

3 · Useful next action

List activities affected, positions that help, triggers and changes over time. Ask for an assessment of tone, strength and joint range, and a plan for transfers or personal care if these are difficult.

4 · Treatment logic

Management may combine positioning, physiotherapy and medicines. Treatments should be chosen around the individual and their goals rather than the amount of stiffness alone.

5 · Deeper explanation

Ask what the proposed intervention targets and how comfort and useful function will be assessed. Record adverse effects as well as any change in spasms.

6 · Evidence and onward routes

Clinical information: N2. These are institutional explainers; the page is sourced, not independently medically reviewed.

For abrupt new neurological symptoms, use urgent medical assessment rather than this reading route.

Useful questions

Uncertainty

Feeling stiff does not confirm spasticity or its cause. This page does not recommend an unsupervised stretching or drug regimen.
