| Methods | Randomised controlled trial with parallel assignment | |
| Participants | Participants: 10 people with PD (5 in experimental and 5 in control group) Inclusion criteria: diagnosis verified by a neurologist, regular treatment with dopamine or other anti‐Parkinsonian drugs Exclusion criteria: history of metal implants in the head, previous surgery for PD, change in medication during study, contamination with other physical therapy during study, pregnancy |
|
| Interventions | 2 arms: (1) Physiotherapy plus anodal tDCS with 1 mA over M1 (hemisphere not stated) twice for 13 minutes with 20 minutes interruption, 3 times a week for 10 sessions (2) Physiotherapy plus sham tDCS with 1 mA over M1 (hemisphere not stated) twice for 0.5 minutes with 20 minutes interruption, 3 times a week for 10 sessions |
|
| Outcomes | Outcome measures were collected at baseline, after the end of the intervention period and at 1‐ month follow‐up Primary outcome measures: UPDRS Secondary outcome measures: Jebsen Taylor Test Parkinson's Disease Quality of Life questionnaire cortical excitability (repetitive transcranial magnetic stimulation ) |

| Notes | The study was completed in September 2012 | |

| Random sequence generation (selection bias) | Unclear risk | Not described |
| Allocation concealment (selection bias) | Low risk | Quote: "The randomization was done by an independent person who selected one of the sealed, sequentially numbered opaque envelopes minutes before the intervention began" (Monte‐Silva 2014 [pers comm]) |
