Minimal depression: how does it relate to upper-extremity impairment and function in stroke?

Area of Science:

• Neurology
• Rehabilitation Medicine
• Psychiatry

Background:

• Stroke frequently leads to upper-extremity (UE) impairment and motor dysfunction.
• Depression is a common comorbidity following stroke, impacting recovery and quality of life.
• The relationship between minimal depression and UE motor function in subacute stroke requires further investigation.

Purpose of the Study:

• To determine the association between minimal depression and upper-extremity (UE) impairment and motor function in subacute stroke survivors.
• To explore potential sex-based differences in depression levels post-stroke.

Main Methods:

• Retrospective analysis of an interventional study cohort.
• Correlational analyses using the Fugl-Meyer Assessment (FM) for UE, the Arm Motor Ability Test (AMAT), and the Beck Depression Inventory (BDI-II).

Main Results:

• A non-statistically significant negative correlation was observed between Beck Depression Inventory scores and both the Fugl-Meyer Assessment (r = -0.120, p = 0.196) and the Arm Motor Ability Test (r = -0.110, p = 0.275).
• Women reported significantly higher depression scores (8.75 ± 0.78) compared to men (6.29 ± 0.46; p = 0.008).

Conclusions:

• Minimal depression levels do not appear to be associated with upper-extremity motor impairment or function in individuals with minimal to moderate UE disability after stroke.
• Post-stroke depression is more prevalent in women, highlighting the need for research into sex-specific differences.
• Understanding these relationships is crucial for optimizing therapeutic strategies for stroke survivors.
