Ask a PT Response: "Were you getting ultrasound from a PT and if so are you still seeing the PT? How did you develop tendinosis of the achilles? Before getting back to running, the underlying factor which contributed to this condition definitley needs to be addressed. Sounds like you are doing the correct things but strengthening alone will not ensure successful return to running. Stretching, postural training, mechanics correction, somatosensory/proprioceptive training, etc. should also be considered. Without physically examining you, it would be difficult for me to give you specific advice. However, with my patients that may have this condition I would usually have them perform/progress to the higher level activities which are performend after an achilles tendon repair ie: http://www.udel.edu/PT/PT%20Clinical%20Services/RehabGuidelines/AchillesRepair.pdf . I hope this helps."
