Upper-Limb Paresis Severity Is Associated With Practice Dosage During Task-Oriented Training in Subacute Stroke-An...

Area of Science:

• Neurorehabilitation
• Stroke Recovery
• Motor Plasticity

Background:

• Intensive, high-repetition practice is crucial for upper-limb task-oriented training (UL-TOT) post-stroke.
• Variability in practice dosage during UL-TOT can impact neural plasticity.
• Factors influencing practice dosage require investigation.

Purpose of the Study:

• To identify factors associated with practice dosage in individuals undergoing UL-TOT after stroke.
• To explore the relationship between clinical variables and achieved repetitions during UL-TOT.

Main Methods:

• Secondary analysis of data from 33 individuals with subacute stroke.
• Stepwise multiple linear regression used to analyze associations.
• Independent variables included age, sex, stroke characteristics, and impairment severity; practice dosage was the dependent variable.

Main Results:

• Upper-limb paresis severity was the sole significant predictor of practice dosage (β = 0.804, p < 0.001).
• The model explained 63.4% of the variance in practice dosage (adjusted R² = 0.634).

Conclusions:

• Upper-limb paresis severity is significantly associated with practice dosage in therapist-guided UL-TOT for subacute stroke.
• Findings suggest motor impairment influences training intensity.
• Further research with larger sample sizes is recommended due to the exploratory nature and small sample size.
