Table 1.

The progression of patient's dorsiflexion degree. AROM is active range of motion, and PROM is passive range of motion. Clinically, PROM is more objective to prevent patients from not wanting to move for some reasons, but excluding such conditions. On the other hand, AROM is the angle that patients can actually move, and our patient's AROM was almost the same as that of the healthy side after three-month treatment, which shows that the treatment effect is promising and satisfies our patient.
