*2.1. Selection Criteria*

We searched in PUB MED electronic database the most relevant studies, using as keywords: "COVID-19 lockdown", "wellbeing lifestyle", "physical activity", "neurodegenerative diseases", "healthy policies" and "telerehabilitation". A literature search was conducted on 1 September 2021. The sorting of the papers was conducted in accordance with the PRISMA flow diagram [12]. In our paper, we selected the most relevant articles, which used modern digital methods and online surveys imposed by the global pandemic COVID-19 lockdown. The articles included the patients with motor and cognitive impairments from neurodegenerative diseases, who were deprived for a long period of time by planned physical exercise or of accessing specialized social assistance services. Additionally, we included the articles focused on healthy adolescents/adults involved in planned physical exercise during the lockdown. The considered publications covered the last 2 years, since the entire world was affected by the imposed lockdown in this time period. We considered only materials published in the English language.
