In this study, thirteen women and one man with averaged age of 21.36 ± 2.13 years were
recruited. All of them were right-handed and had both sides of MPS. This study found two sides of
active and twelve sides of latent MPS in group 1. For group 2, there were four sides of active and ten
sides of latent MPS. Most active MPS found in the subjects were changed to latent MPS at end of first
treatment, excepted one subject in group 2. At end of treatment, all of active MPS were changed to
latent MPS.
