Question About Achilles Tendon on Affected Side

Hi guys.

So I've brought this up before because I thought it happened with all strokes, but was told it didn't. I had foot drop initially after my hemorrhagic stroke, and was told it was due to my Achilles tendon disconnecting. This made sense to me. I've since had surgery to reattach it and it's helped a lot, as I no longer roll my foot (I used to have to wear shoes in the house to prevent crushing my poor toes). I used to also play the drums, but have had to stop since the stroke due to the loss of my dorsiflexion on my affected (right) side.

Any insight on this? I've Google it and see some studies, but I wasn't sure how many other survivors dealt with this.
