OBJECTIVES: To examine peak and cumulative patellofemoral joint force when adolescents with patellofemoral pain run in a traditional athletic shoe, compared with a flat, flexible shoe.
DESIGN: Cross-sectional.
PARTICIPANTS: Twenty-six adolescents with patellofemoral pain ran on an instrumented treadmill in a traditional athletic shoe and a flat, flexible shoe.
MAIN OUTCOME MEASURES: Cumulative and peak patellofemoral joint forces, knee flexion angle, knee extension and ankle plantarflexion moments, cadence, stride length and pain were compared between footwear conditions using paired t-tests.
RESULTS: Peak patellofemoral joint reaction force was 11 % (p < 0.001) lower while running in the flat, flexible shoe (mean ± SD 3.62 ± 1.01 N/kg), compared to the athletic shoe (4.09 ± 0.97 N/kg). Cumulative patellofemoral joint force was 15 % (p < 0.001) lower while running in the flat, flexible shoe (195.09 ± 75.97 Bw.s/km), compared to the athletic shoe (231.54 ± 87.95 Bw.s/km). Peak knee flexion angle (p < 0.001) and knee extension moment (p = 0.001) were also lower when running in the flat, flexible shoe. There was no difference in peak ankle plantarflexion moment, running cadence, stride length, or pain between conditions.
CONCLUSIONS: Flat, flexible shoes may be a suitable intervention to lower cumulative patellofemoral joint loads during running in adolescents with patellofemoral pain.
