Sleep disturbances negatively affect balance and gait function in post-stroke patients

Area of Science:

• Neurology
• Rehabilitation Medicine
• Sleep Science

Background:

• Impaired gait and balance significantly contribute to disability post-stroke.
• Sleep disturbances are increasingly recognized as detrimental to functional recovery in stroke patients.

Purpose of the Study:

• To investigate the impact of sleep disturbances on balance and gait function in stroke patients.
• To identify sleep disturbance as a predictor of functional outcomes after stroke.

Main Methods:

• Retrospective review of 140 first-ever stroke patients.
• Group comparison based on the presence of sleep disturbances.
• Analysis of demographic data, lesion factors, initial balance, and gait function, including lesion volume and 1-month rehabilitation outcomes.
• Linear regression to identify predictors of balance and gait function.

Main Results:

• 25% of stroke patients experienced sleep disturbances and were older.
• Sleep disturbance was associated with poorer balance and gait function (e.g., Berg Balance Scale, Functional Ambulation Categories, 10-meter walk velocity).
• Initial balance and sleep disturbance predicted balance and gait outcomes at 1 month.

Conclusions:

• Sleep disturbances negatively impact functional outcomes, particularly balance and gait, in stroke patients.
• Management of sleep problems is recommended to enhance recovery and improve overall outcomes in stroke rehabilitation.
