You can get the necessary article in the field of rehabilitation programs after an Achilles tendon rupture surgery in PubMed, SCOPUS, Google, Google Scholar etc

Thank you both Achmad and Pier. After some more time and resarch I found the correct articles for the information I needed.

Search for Dr. Håkan Alfredson, pioneer of some key Achilles tendon rehabilitation techniques.

Thank you very much Dr. Richardson. Indeed a lot of information from Dr. Alfredson about achilles rehabilitation techniques, though most of his field of experise is tendinopathy. But stil  a good name to remember :-)
