Interventions for preventing falls in Parkinson's disease.

Area of Science:

• Neurology
• Geriatrics
• Rehabilitation Medicine

Background:

• Parkinson's disease (PD) significantly increases fall risk.
• Falls in PD can lead to fractures, reduced quality of life, and increased healthcare costs.
• Evidence-based fall prevention strategies are crucial for managing PD progression.

Purpose of the Study:

• To synthesize evidence on interventions for reducing falls in Parkinson's disease.
• To assess the effectiveness and certainty of evidence for various fall prevention strategies.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials (RCTs).
• Searched multiple databases (CENTRAL, MEDLINE, Embase) up to October 2021.
• Included RCTs reporting fall outcomes; assessed evidence certainty using GRADE.

Main Results:

• Exercise interventions probably reduce fall rates by 26% and slightly reduce the number of people falling (moderate certainty).
• Cholinesterase inhibitors may reduce fall rates by 50% but increase non-fall-related adverse events (low certainty).
• Evidence for fall-prevention education and combined exercise/education interventions is uncertain due to very low to low certainty.

Conclusions:

• Exercise is likely effective in reducing falls in mild to moderate Parkinson's disease.
• Cholinesterase inhibitors offer a potential fall reduction but require balancing against adverse events.
• High-quality RCTs are needed to clarify optimal exercise protocols, medication effects, and educational interventions.
