VIRTUAL WALKING and TRANSCRANIAL DIRECT CURRENT STIMULATION (TDCS) for CHRONIC NEUROPATHIC PAIN DUE to SPINAL CORD INJURY (SCI): a FEASIBILITY STUDY
The goal of this feasibility study is to assess the feasibility of the combined treatment intervention virtual walking (VW) and transcranial direct current stimulation (tDCS) of neuropathic pain in patients with spinal cord injury. The main question aims to answer: • To assess the feasibility of combining VW and tDCS for longer-term use from the patients' point of view. Participants will: Receive a two week intervention in the Swiss Paraplegic Centre in Nottwil, where the participants undergo VW and tDCS for ten sessions, each lasting around 20 minutes. The participants keep a diary and a pain drawing of their symptoms and will fill out some questionnaires about their impression of feasibility, the pain intensity, chronicity, the impression of change, depression, anxiety, stress and adverse events. At the beginning and end of the study the participants will be interviewed about their expectations, hopes and the feasibility of the procedures from a participants point of view.
