Accepted Answer

3DGait Achieves Approximately 95% Accuracy Compared to Motion Analysis Labs

The 3DGait application demonstrates a high level of accuracy when compared to traditional motion analysis laboratories. In benchmarks, 3DGait achieved approximately 95% accuracy. Specifically, its angular measurements are within three degrees of the gold standard, and its spatial-temporal measurements are accurate to within three centimeters and 0.03 seconds, which corresponds to a single frame of video.
Angular Measurement Precision

In terms of angular measurements, 3DGait's performance is closely aligned with the established gold standard. The application consistently falls within a three-degree margin of error. This level of precision is critical for analyses that rely on the precise angles of body joints during movement.
Spatial-Temporal Measurement Accuracy

For spatial-temporal measurements, 3DGait exhibits accuracy within three centimeters for distance and 0.03 seconds for time. This temporal accuracy is equivalent to the precision of a single video frame, allowing for detailed analysis of movement speed and progression over very short intervals.
Development and Application Context

Developed by CareCam, the 3DGait app was created over a period of two to three years from inception to its first version. Its design allows for gait analysis using an iPad, requiring no internet connection or physical contact with the user. This approach simplifies the process, making it significantly less expensive and more comfortable than traditional methods that involve strapping patients to sensors and equipment. The application has been used in Singapore's age care centres, where individuals walk a short distance of six to eight meters for analysis.
