► A visual feedback system to correct pelvis and trunk movements has been evaluated. ► Gait pattern differed in healthy woman and woman with gait disorders. ► Gait pattern improved in woman with gait disorders while using this system. ► The feedback system may be beneficial in gait retraining e.g. in THR patients. Abnormal gait pattern of the frontal plane (i.e. Duchenne gait and Trendelenburg gait) may be caused by a variety of diseases. The aim of this pilot study was to evaluate the instantaneous effect of a visual feedback system on frontal plane pelvis and trunk movements in order to use it in patients with THR in subsequent studies. A total of 24 women (45–65 years) were included in the study. According to acute functional impairments the subjects were assigned to the control group (CG, no gait disorders, = 15, age = 59 ± 11 years, BMI = 27 ± 4) or to the intervention group (IG, = 9, age = 61 ± 4, BMI = 29 ± 5), respectively. First, in Measurement 1 (M1) kinematic reference values were captured in a standardized clinical gait analysis (MVN, XSens). Afterwards, the influence of a visual real-time feedback on gait pattern was examined while using the feedback system (M2). While there was a significant difference of IG vs. CG in M1 in the mean inclination regarding pelvis and trunk movements, this was not detected in M2. Therefore it is concluded, especially in subjects with abnormal gait pattern, that the visualization leads to an improvement of the movement pattern of pelvis and trunk in the frontal plane while using the device.
