Inclusion criteria

Inclusion criteria: 1) Intervention group: The inclusion criteria for a stage II PTTD classification required subjects to have 1 or more signs related to posterior tibial tendon dysfunction, including (1) palpable tenderness of the posterior tibial tendon, (2) swelling of the posterior tibial tendon sheath and (3) pain during single-limb heel raise, and 1 or more signs of flexible flatfoot deformity including excessive non-fixed rearfoot valgus deformity during weight bearing, excessive forefoot abduction, or demonstrated loss of height in the medial longitudinal arch based on the Johnson and Strom’s classification. Flexible foot deformity were determined with navicular drop test (=10mm). The Foot Posture Index (FPI) score were measured to determine the overall pronated foot deformity (=+6). In addition, Visual analog scale (VAS) was also used to assess localized pain around tendon during palpation. 2) No intervention group: Subjects who do not have flexible foot deformity and do not have any pain in the posterior tibial tendon.

Exclusion criteria

Exclusion criteria: Subjects who have Idiopathic flatfoot, fixed foot deformity (Navicular drop test <10mm), previous foot surgery, peripheral vascular or other musculoskeletal pathology.
