Resisted ankle dorsiflexion (Ankle dorsiflexion strengthening, with band, sitting legs straight)

Start in a seated position with your legs extended.
Take the band and place it around your feet.
Next, bend your knee on the affected side so that your heel is resting on your shin.
Pull the toes of the affected side up towards your head as you maintain tension in the band.
The unaffected foot acts as an anchor to allow more tension to be created in the band.
Relax to the starting position and repeat.
