Phantom limb pain
Conditions
Interventions
Two types of training are used as interventions: real training and sham training.
1) Real training. DecNef training is performed using a decoder created using magnetoencephalographic signals from whe

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in average VAS in the 7 days after the end of the 2-month training from the average VAS in the 7 days before the training (%), comparison between real training and sham training | — |
Secondary
| Measure | Time frame |
|---|---|
| (1) Change in average SF-MPQ2 total value in the 7 days following the end of the 2-month training period from the average SF-MPQ2 total value in the 7 days prior to training (%) , comparison between real training and sham training (2) Number of days in which the VAS value after each training session is lower than 70% of the average 7-day VAS value before training , comparison between real training and sham training (3) Number of adverse events other than pain change , comparison between real training and sham training (4) The classification accuracy of magnetoencephalography during the phantom hand movements, and the changes of the classification accuracy before and after training | — |
