Insights
Locomotion disorders worsen in early Huntington's disease (HD). Gait initiation and performance decline, linked to initial functional capacity and motor impairment severity in HD patients.
Area of Science:
- Neurology
- Movement Disorders
- Huntington's Disease Research
Context:
- Locomotion disorders are a significant feature of Huntington's disease (HD).
- The progression of gait and gait initiation issues in early-stage HD is not well understood.
- Previous studies focused on motor, functional, or cognitive changes, leaving a gap in understanding locomotion evolution.
Purpose:
- To quantify the rate of progression for gait and gait initiation disorders in Huntington's disease.
- To identify factors correlating with the evolution of locomotion deficits in early HD.
- To analyze changes in anticipatory postural adjustments (APA), gait speed, stride time, and stride length.
Summary:
- Evaluated 18 HD patients over at least one year, assessing APA, gait speed, stride time, and stride length.
- Observed worsening in APA, correlating with akinesia, and decreased gait speed due to increased stride time and reduced stride length.
- Stride-to-stride variability remained stable, but gait initiation and performance deteriorated.
Impact:
- Demonstrates a clear progression of gait and gait initiation problems in early HD.
- Suggests that lower initial functional capacity and greater motor impairment predict faster locomotion decline in HD patients.
- Provides crucial data for understanding disease progression and developing targeted interventions for HD-related movement disorders.
Introduction:
Locomotion disorders are important in Huntington's disease (HD). Although the rates of evolution of motor, functional or cognitive aspects of HD have been studied, the evolution of locomotion disorders in early stages of the disease remains unknown.
Objectives:
To determine the rate of evolution of the HD-associated gait and gait initiation disorders and their correlates.
Patients And Methods:
Eighteen HD patients were recorded with a minimum interevaluation interval of one year. Akinesia was studied by evaluating the anticipatory postural adjustment (APA) phase preceding the first step. We also evaluated gait speed, stride time and stride length.
Results:
We observed an alteration in the APA phase, whose evolution was correlated with that of akinesia. We also observed a decrease in gait speed, which was due both to an increase in stride time and a decrease in stride length. Stride-to-stride variability did not worsen between both evaluations.
Conclusions:
A worsening in both gait initiation and gait performance was observed in HD. Initial weak functional capacity and more severe motor impairment seem to be associated with a faster progression of locomotion parameters in these mildly impaired HD patients.
