Eligible participants are adults with idiopathic PD. Interventions include immersive or non-immersive VR-TR with remote supervision, compared with conventional physiotherapy, usual care or other active non-VR interventions. Primary outcomes are balance, gait and global motor function; secondary outcomes are quality of life and adverse events. Two reviewers will independently screen, extract data and assess risk of bias. Where possible, meta-analyses will be conducted using RevMan V.5.4, and the certainty of evidence will be appraised with Grading of Recommendations Assessment, Development and Evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>This study does not involve human participants and uses data from published studies; therefore, ethics approval is not required.
