Gait, balance, and falls in Huntington disease

Area of Science:

• Neuroscience
• Movement Disorders
• Gerontology

Background:

• Huntington disease (HD) is a progressive neurodegenerative disorder.
• Gait and balance impairments are hallmark symptoms of HD, significantly affecting patient quality of life and predicting nursing home placement.
• Existing research highlights motor, cognitive, and psychiatric symptoms in HD, with falls being a major concern.

Purpose of the Study:

• To review the characteristics of gait and balance impairments in Huntington disease.
• To identify intrinsic and extrinsic factors contributing to fall risk in people with HD.
• To assess the current evidence for interventions and highlight the need for fall-specific research in HD.

Main Methods:

• Literature review of studies on gait, balance, and falls in Huntington disease.
• Analysis of spatiotemporal gait parameters, balance measures, and fall-related factors.
• Evaluation of existing exercise intervention evidence for HD-related motor deficits.

Main Results:

• Gait impairment in HD includes bradykinesia, reduced velocity, increased variability, and altered symmetry and step length.
• Balance deficits involve impairments in anticipatory (with and without base of support change) and reactive balance.
• Increased fall risk in HD is multifactorial, including gait/balance deficits and reduced cognitive reserve for dual tasking.

Conclusions:

• Exercise interventions show potential for addressing some HD-specific gait and balance deficits.
• No intervention studies have specifically targeted fall prevention in Huntington disease to date.
• Large, well-designed randomized controlled trials are essential for developing effective fall prevention strategies for individuals with HD.
