The effects of gait retraining in runners with patellofemoral pain: A randomized trial

2018 Consensus statement on exercise therapy and physical interventions (orthoses, taping and manual therapy) to treat patellofemoral pain: recommendations from the 5th International Patellofemoral Pain Research Retreat, Gold Coast, Australia, 2017

“…Esculier et al 18 reported no effects on pain and function over 5 months when gait retraining (personalised programme focused on increasing step rate, landing softer and adopting a non-rearfoot strike pattern) combined with load management education was compared with exercise and load management education, or load management education alone, in runners with patellofemoral pain (n=69). In comparison, a small RCT of 16 runners who were self-reported rearfoot strikers found that 2 weeks of gait retraining (focused on transitioning from rearfoot to forefoot strike pattern) significantly reduced patellofemoral pain immediately after retraining and at 1-month follow-up, compared with no intervention 30. Differences between the two studies extend beyond the selection of runners (eg, rearfoot strikers30 vs any footstrike pattern18), choice of running retraining techniques, choice of comparator and sample size, to approaches used to attain gait retraining effects (eg, motor retraining principles) 41 42.…”

It is recommended that robust RCTs of gait retraining of runners (and walkers) with patellofemoral pain be conducted.…”

Response to: ’Optimising the efficacy of gait retraining'

“…But is gait retraining better than other interventions, such as an educated return to running or an exercise programme? Besides our study, only Roper et al 8 have included a control group, which generically decreased running volume and increased it back to baseline after only 2 weeks. Even though gait retraining yielded better results, controls’ pain scores decreased by a non-statistically significant margin of 1.7/10 after the programme.…”

Modelagem de interação entre sinais cinemáticos durante o exercício

“…Uma maneira de estudar as RRI é pela utilização de dados cinemáticos (DUDLEY et al, 2017;KUHMAN et al, 2016), que permite medir modificações na dinâmica dos membros inferiores em corredores que alteraram para corrida descalço (HASHISH et al, 2015), aterrissagem com antepé (ROPER et al, 2016), e corrida com os dedos do pé (POHL;BUCKLEY, 2008). Outro emprego desses dados é comparar o movimento do pé de atletas com arco plantar (POWELL et al, 2011) e corredores com sobrepronação (ZHANG; AELES; VANWANSEELE, 2017).…”

“…Muitos estudos utilizaram software estatístico, como IBM SPSS Statistics (IBM Corp., Armonk, NY, EUA) (ANBARIAN; ESMAEILI, 2016;DUDLEY et al, 2017;HO et al, 2014;KUHMAN et al, 2016;PAZZINATTO et al, 2017;ROPER et al, 2016;ZHANG;AELES;VANWANSEELE, 2017), PASS (NCSS Statistical, Kaysville, UT, EUA) (CHEUNG et al, 2016;HASHISH et al, 2015) (POWELL et al, 2011). Contudo, a cinemática de tronco, pelve e membros inferiores durante a corrida é complexa e, por esse motivo, ainda não é completamente compreendida (PANDY; ANDRIACCHI, 2010).…”
