- Abstract
- Specific kinematic actions of the spine and shoulder are useful for low back pain (LBP) assessment and treatment. However, the widespread application of motion capture systems in clinical settings is limited by the tedious process and expensive equipment. As a cost-effective and portable device, Kinect has the potential to be used in clinical analysis and rehabilitation for patients with LBP. Using Kinect and a motion capture system, 10healthysubjectsperformed left/right bending and extension tasks five times successively with and without simulated motion limitations. The mean range of motion (ROM)and maximum angular velocity (MAV) were then calculated. The results revealed that the Pearson's correlation coefficient was more than 0.7 with ROM. The root-mean-square error (RMSE) of the ROM difference, with and without motion limitation, was1.2–3 (for MAV: 4.7/s–14.6/s). In conclusion, Kinect can be used as an analysis tool for kinematic variability of shoulder and trunk motion, which could help obtain low back information regarding movement patterns and strategies under various movement tasks.
