Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

With the far infrared ray applied to the 'phantom limbs' in amputees and the corresponding normal legs in healthy subjects, the sensation of (phantom) limb will be assessed for each subject using the techniques of fMRI and meridian response.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This project will investigate two main hypotheses based on our previous studies on phantom limb sensation and phantom limb pain. The first hypothesis states that phantom limb sensation and phantom limb pain both correlate with the 'phantom limb', while the second one maintains that the phantom limb can interact with the patient's body by means of the meridian system. With the far infrared ray applied to the 'phantom limbs' in amputees and the corresponding normal legs in healthy subjects, the sensation of (phantom) limb will be assessed for each subject using the techniques of fMRI and meridian response. By analyzing the data collected from both groups, the investigators expect both hypotheses will be supported by the results of experiments in this project.
