Understanding Freezing of Gait: New Review Identifies Key Movement Differences in Parkinson’s Disease
Silva-Batista, Carlos, et al. “Systematic Review of Kinematic and Kinetic Parameters in Parkinson’s Disease, With and Without Freezing of Gait.” Clinical Biomechanics, April 2025. https://pubmed.ncbi.nlm.nih.gov/42048981/.

Freezing of gait is one of the most frustrating and potentially dangerous symptoms of Parkinson’s disease. During a freezing episode, a person's feet may suddenly feel stuck to the ground, increasing the risk of falls and reducing independence. A 2025 systematic review published in Clinical Biomechanics examined dozens of studies to better understand the movement patterns associated with freezing of gait.

Researchers analyzed kinematic and kinetic measurements collected from people with Parkinson’s disease who experience freezing episodes and compared them with individuals who do not freeze. The review evaluated factors such as stride length, walking speed, balance control and lower-limb movement patterns.

The researchers found consistent differences between the two groups. Individuals who experienced freezing of gait often demonstrated shorter steps, greater variability in movement and altered balance characteristics. These findings suggest that measurable changes in walking mechanics may occur before freezing episodes become apparent.
The review provides valuable information for clinicians developing assessment tools, rehabilitation programs and fall-prevention strategies. Understanding the mechanics of freezing may also help researchers create new interventions that target the underlying causes of this disabling symptom.

Although freezing of gait remains difficult to treat, this comprehensive review offers important insights that may guide future therapies and improve quality of life for people living with Parkinson’s disease.
