Impaired dynamic balance is associated with falling in post-stroke patients

Area of Science:

• Neurology
• Rehabilitation Medicine
• Gerontology

Background:

• Falls are a frequent complication following stroke.
• Impaired balance, cognitive deficits, and reduced physical function contribute to fall risk in stroke survivors.

Purpose of the Study:

• To examine the impact of falls on cognitive and physical functioning in post-stroke patients.
• To identify predictors of independence in activities of daily living (ADL) among stroke patients with a history of falls.

Main Methods:

• Sixty-six stroke patients were categorized into fallers (n=34) and non-fallers (n=32).
• Cognitive function was assessed using the Mini-Mental State Examination (MMSE).
• Physical function, static and dynamic balance (postural sway, Berg Balance Scale [BBS], Modified Rivermead Mobility Index [MRMI]), and ADL independence (Modified Barthel Index [MBI]) were evaluated.

Main Results:

• Fallers demonstrated significantly lower cognitive and physical function compared to non-fallers (p < 0.05).
• In fallers, ADL (MBI) showed moderate correlations with cognition (MMSE), dynamic balance (MRMI, BBS).
• Regression analysis identified BBS as a key predictor of ADL performance (R²=0.327, p < 0.000).

Conclusions:

• Falls in stroke patients are associated with deficits in both physical and cognitive functions.
• Dynamic balance, particularly as measured by the BBS, is a critical factor for maintaining independence in daily activities for stroke survivors who fall.
• Interventions focused on enhancing dynamic balance are essential for improving self-care and overall function in this population.
