Abstract

Objectives: Analyze the effects of 3 gait retraining: forefoot landing (FFOOT), 10% step rate increase (SR10%) and forward trunk lean (FTL) on lower limb biomechanics and clinical measurements in patellofemoral pain (PFP) runners. Design: Case series report. Settings: Biomechanical laboratory and treadmill running. Participants: Eighteen recreational PFP runners randomized in 3 groups. Main outcome measures: Lower limb kinematics and muscle activation were assessed at baseline and 2-week post-training. Pain intensity and function limitation, measured by AKPS (Anterior Knee Pain Scale) and LEFS (Lower Extremity Functional Scale) assessed at baseline, post-training and 6-month follow-up. Repeated measures analysis of variance was used to compare the effects of gait retraining. Results: FFOOT and FTL increased the AKPS score at post-training(P =.001; P =.008) and 6-month follow-up(P < .001; P < .001). SR10% increased the AKPS score from baseline to 6-month followup(P =.006). Pain and LEFS score were improved after gait retraining regardless group. FFOOT presented greater gastrocnemius(P = .037) and rectus femoris pre-activation(P =.006) at post-retraining session. Gait retraining reduced the muscle activity during stance phase and increased during the late-swing regardless group. Conclusion: The three techniques presented clinical benefits, improvement of pain symptoms and functional scores, was not accompanied with significant biomechanics differences that could entirely explain this clinical improvement after the intervention.
