PURPOSE OF THE STUDY:
In this pilot study, gait analysis was performed before and after training with a 3D pedal system (BIUS1), in order to clarify whether these differences are detectable by gait analysis after a short period of training.

MATERIAL AND METHODS:
Two female and three male subjects were included in a prospective case-control pilot study. The patient and training characteristics were determined. Objective measurement data of the gait were obtained by using a three-dimensional motion analysis system with six infrared cameras and three force plates before and after training with the 3D pedal system.

RESULTS:
The mean age was 36.7 ± 8.7 years and the subjects had a BMI of 21.8 ± 2.4 kg/m². The training time per year was an average of 36.0 ± 11.2 days, with a training workload of 511.4 ± 36.7 km.
For time-distance parameters, improvements for the left and right side were obtained for cadence and cycle time after training. In total, there was a reduction in hip abduction angle, and an increase in hip inward rotation, knee outward rotation, and range of the frontal knee angle.

CONCLUSIONS:
Changes in parameters in the gait analysis after a short training interval demonstrate that a 3D pedal system is suitable to produce changes in the gait pattern detectable by gait analysis. Training effects on the supposedly weaker left side can be explained after a brief application of the BIUS1 system.
