How to use this calculator
- Choose the test you used.
- Enter your first and latest results and the weeks between them.
- See percentage change and weekly rate.
How it works
Strength change is shown as a percentage of the first result. Early in a programme, gains of 1 to 3 percent a week are typical, largely from better nerve activation; muscle growth adds more over months.
Reading your result
| 20% or more | Strong progress. |
|---|---|
| 5 to 20% | Some progress. |
| Under 5% | Plateau or decline. |
Physiotherapy treatment
Strength progression is the core of physiotherapy for muscle weakness. After an assessment, your physiotherapist sets a plan built around progressive resistance and functional strengthening, progressed as your results improve. Hands-on treatment, pain relief and education are added where they help.
