AI InsightDuring BW, the ratio of the PFPS groupwas significantly higher than compared to the healthy controls (p=0.016) without any significant difference between the groups during FW(p=0.100).Conclusion: Our study results show that BW increases the VMO muscle activation and preserve the ideal VMO/VL ratio in PFPS patients.Therefore, clinicians should consider BW training when developing rehabilitation programs for females with PFPS.

Objectives: This study aims to examine the effect of backward walking (BW) and forward walking (FW) on the myoelectric activity ratio ofthe vastus medialis oblique (VMO)/vastus lateralis (VL) in females with patellofemoral pain syndrome (PFPS).Patients and methods: Between September 2016 and December 2016, a total of 40 female participants (mean age 20.9±1.9 years;range, 19 to 26 years) were included in the study. The participants were divided into two groups as those with unilateral PFPS(PFPS group, n=20) and healthy controls (Control group, n=20). Surface electromyography (EMG) from VMO and VL muscles were collectedduring FW and BW at a speed of 3 km/h using the Myomonitor® IV EMG system.Results: There was a significant increase in the EMG activities of the VMO and VL muscles during BW compared to FW in PFPS andhealthy groups (p=0.001). During BW, the VMO activity of PFPS was significantly higher than the healthy controls (p=0.013) without anysignificant difference in the VL activity (p=0.916). During FW, there was no significant difference in the VMO and VL activities between thegroups (p=0.348 and p=0.705), respectively. The VMO/VL ratio of the PFPS group during BW was significantly higher than the FW ratio(p=0.001) without any significant difference between BW and FW of the healthy group (p=0.841). During BW, the ratio of the PFPS groupwas significantly higher than compared to the healthy controls (p=0.016) without any significant difference between the groups during FW(p=0.100).Conclusion: Our study results show that BW increases the VMO muscle activation and preserve the ideal VMO/VL ratio in PFPS patients.Therefore, clinicians should consider BW training when developing rehabilitation programs for females with PFPS.
