Abstract

The aim of this study was to compare the functional capacity of women with patellofemoral pain (PFP) according to their body mass index (BMI). Forty-eight women with PFP aged 18 to 35 years were divided into three groups: PFP normal weight, PFP overweight and PFP obesity. The level of pain, the level of physical activity and the self-reported functional capacity were obtained through the visual analogue pain scale (VAS), from the Baecke and Anterior Knee Pain Scale (AKPS) questionnaires, respectively. Then, the objective functional capacity was obtained by the participants' performance during the forward step-down test, single-leg hop test and prone and side bridge tests. Finally, the peak torque of the knee extensor and hip abductor muscles was obtained using an isokinetic dynamometer. For comparison between groups, one-way analysis of variance (ANOVA) (parametric data) and Kruskal-wallis test (nonparametric data) were performed. The significance level was α <0.05. There were no significant difference in pain level (F(2,45)=0.842; p=0.437) and physical activity (F(2.45)=0.394, p=0.677) between the groups. The PFP obesity group had lower self-reported functional capacity compared to the PFP normal weight group (p=0.006; d=1.21); lower performance in the forward step down test compared to the PFP normal weight (p<0.001; d=1.76) and PFP overweight (p<0.016; d=1.39) groups; lower performance in the single-leg hop test compared to the PFP overweight group (p=0.014; d=1.12). In relation to the bridges test, the PFP obesity group had lower performance in the left side bridge test compared to the PFP normal weight (U=32.50; p<0.001; d=1.65) and PFP overweight groups (U=48.00; p<0.01; d=1.26) and had lower performance on the right side bridge test compared to the PFP normal weight group (U=29.00; p <0,001; d=1.75). Finally, the PFP obesity group had lower peak isometric knee extensor torque compared to the PFP normal weight group (p=0.001; d=1.29) and lower isometric hip abductor torque compared to the PFP normal weight group (p<0.001; d=1.72) and PFP overweight (p=0.002; d =1.26). It was concluded that there was no difference in the level of pain and physical activity between the groups, but obesity had a negative influence on the self-reported and objective functional capacity of women with PFP.
