Test-retest reliability of static postural control in people with multiple sclerosis

Area of Science:

• Neurology
• Biomedical Engineering
• Rehabilitation Science

Background:

• Multiple Sclerosis (MS) is a chronic neurological disease affecting balance and mobility.
• Postural control assessment is crucial for managing MS progression.
• Stabilometry provides objective measures of postural control.

Purpose of the Study:

• To evaluate the intraday test-retest reliability of stabilometric measurements of the Centre of Pressure (CoP).
• To determine the consistency of CoP measurements in individuals with Multiple Sclerosis (MS) under various conditions.

Main Methods:

• 18 participants with MS underwent stabilometric testing on a force platform.
• Measurements were taken with eyes open/closed on rigid and foam surfaces.
• Intraclass correlation coefficient (ICC) and coefficient of variation (CV) assessed reliability.

Main Results:

• High reliability (ICC=0.69-0.92) was observed for CoP measurements across all conditions.
• X Speed, Y Speed, and Side Length demonstrated the highest consistency.
• Intraday test-retest reliability was good to excellent.

Conclusions:

• Stabilometric measures, particularly X Speed, Y Speed, and Side Length, are reliable for assessing postural control in MS.
• These variables can be effectively used for monitoring disease progression and treatment efficacy in MS patients.
