Predicting Activities of Daily Living (ADL) Outcomes in Recovery-Phase Stroke Patients Using the Trunk Impairment...

Area of Science:

• Neurology
• Rehabilitation Medicine
• Clinical Outcomes Research

Background:

• Trunk function is crucial for activities of daily living (ADL) post-stroke.
• The prognostic value of the Trunk Impairment Scale (TIS) during stroke recovery requires further investigation.

Purpose of the Study:

• To develop and validate a model predicting discharge ADL using the TIS in stroke patients during the recovery phase.
• To assess the TIS's utility in forecasting functional outcomes for individualized rehabilitation.

Main Methods:

• Prospective cohort study of 80 first-ever stroke patients.
• Assessed trunk function (TIS), motor function (SIAS-M), stroke severity (NIHSS), and ADL (FIM-M).
• Compared three regression models and validated predictive accuracy using cross-validation and bootstrap analysis.

Main Results:

• The TIS-based model demonstrated the highest predictive accuracy for discharge ADL.
• The TIS model outperformed models based on baseline and motor function.
• Bootstrap analysis confirmed the independent prognostic contribution of the one-month TIS score.

Conclusions:

• The Trunk Impairment Scale (TIS) is a reliable predictor of ADL outcomes at discharge when assessed one month after stroke.
• The TIS can aid in tailoring rehabilitation strategies for stroke survivors.
• Integrating TIS assessment into clinical practice can enhance stroke recovery planning.
