Area of Science:

Neurology
Biomechanics
Rehabilitation Medicine

Background:

Gait dysfunction is a significant challenge in patients with ataxia and post-stroke hemiparesis.
Accurate assessment of gait parameters is crucial for diagnosis and rehabilitation planning.

Purpose of the Study:

To evaluate the informativity, sensitivity, and specificity of the LA-1 «Laser Analyzer of Kinematic Gait Parameters» for assessing gait in patients with ataxia and post-stroke hemiparesis.
To establish normative gait parameters in healthy individuals and identify deviations in patient groups.

Main Methods:

Gait parameters (tempo-rhythm, spatial) were measured in healthy adults (n=60) and patients with ataxia (n=30) or post-stroke hemiparesis (n=30) using the LA-1 analyzer.
Key parameters analyzed included step length, step duration, their standard deviations, and coefficients of variability.

Main Results:

The LA-1 method demonstrated high sensitivity and specificity in distinguishing between healthy individuals and patients.
Patients exhibited increased step length, duration, standard deviations, and variability, alongside decreased walking speed.
Normative gait values for healthy individuals were established.

Conclusions:

The LA-1 Laser Analyzer is a sensitive and specific tool for evaluating gait in ataxia and post-stroke hemiparesis.
The identified gait changes in patients align with previous research findings.
The LA-1 method is recommended for clinical application in assessing gait disorders.
