Therapeutic exercise
Low Step-Up
Functional closed-chain exercise with progressive load. Rehabilitates the ability to climb stairs, the main functional limitation in knee osteoarthritis.
How to perform
- Starting position. Stand in front of a low step (10–15 cm).
- Step 2. Place the affected foot on the step and transfer your weight, stepping up with control.
- Step 3. Avoid pushing off with the back foot — the affected leg does the work.
- Return. Step down with control and alternate sides.
When not to perform
- Acute pain on ascent
- Instability with a giving-way sensation
