Movement strategies during obstacle crossing in people with Parkinson disease: A systematic review with meta-analysis.

Objective: Navigating obstacles involves adjusting walking patterns, particularly when stepping over them. This task may be particularly challenging for people with Parkinson disease (PD) for several reasons. This review aims to compare the spatiotemporal gait parameters of people with and without PD while stepping over obstacles.

Arm swing asymmetry in people with Parkinson's disease and its relationship with gait: A systematic review and meta-analysis.

Background: Individuals with Parkinson's disease present arm swing alterations that can adversely affect their locomotion.

Objective: To identify differences in arm swing asymmetry (ASA) between individuals with Parkinson's disease (PD) and healthy individuals and to investigate the relationship between ASA, temporal-spatial gait parameters, and disease progression.

Methods: A literature search was conducted in PubMed, Scopus, ProQuest, Web of Science, and EBSCOhost up to February 2023.

Food systems for sustainable development: proposals for a profound four-part transformation.

Evidence shows the importance of food systems for sustainable development: they are at the nexus that links food security, nutrition, and human health, the viability of ecosystems, climate change, and social justice. However, agricultural policies tend to focus on food supply, and sometimes, on mechanisms to address negative externalities. We propose an alternative.
