Alignment static and dynamic rearfoot does not differentiate subjects with and without patellofemoral pain syndrome
AbstractAmong the various factors involved in the etiology of femoropatelar pain syndrome (FPPS) are the changes in hindfoot alignment. This study aimed to compare the static and dynamic alignment of the rearfoot in subjects with and without FPPS. Participants were 51 female subjects, 23 with a clinical diagnosis of FPPS (FPPSG) and 28 clinically healthy (CG). It was evaluated the static angles of the rearfoot in accordance to the protocol for Postural Assessment Software (SAPO), and dynamic with the Ariel Performance Analysis System (APAS). It was computed independent t-test and ANOVA 2-ways (p≤ 0.05). No differences were observed (p= 0.08) for the rearfoot angle between between static (FPPSG = 7.91°±4.45°; CG = 5.92°±3.69°) and dynamic (FPPSG = 9.57°±3.66°; CG= 9.19°±3.08°) groups. There were also no differences between groups (p= 0.22) comparing the variation between static and dynamic situations (CG= 3.27°±4.59°; FPPSG = 1.65°±4.84°). Subjects with PFPS have no changes in the static and dynamic postural alignment of the rearfoot relative to subjects without this condition.
