Objective:

To provide empirical evidence supporting the integration of pulmonary assessment into multidisciplinary stroke rehabilitation by examining associations between pulmonary function parameters and functional domains in stroke survivors.

Approach:
    Key Findings:
    • BBS and FMA-LE scores positively correlated with VC%, FEV1%, and PEF% (r = 0.30–0.48, p < 0.05).
    • TIS scores positively associated with multiple pulmonary parameters (VC%, IC%, FVC%, FEV1%, FEV1/FVC, PEF%, MVV%; r = 0.31–0.54, p < 0.05).
    • Strongest correlation observed between TIS and PEF% (r = 0.54, p < 0.001).
    • PEF% negatively correlated with COP path length and velocity (rs = −0.30 to −0.33, p < 0.05).
    • 95% confidence ellipse area negatively correlated with IC% (rs = −0.40, p < 0.01) and PEF% (rs = −0.34, p < 0.05).
    Interpretation:

    The results support the integration of simple pulmonary screening, particularly PEF measurement, into stroke rehabilitation workflows to enhance multidisciplinary collaboration.

    Limitations:
    • The study is observational and cross-sectional, limiting causal inferences.
    • Sample size may restrict generalizability of findings.
    Conclusion:

    Integrating pulmonary assessment into stroke rehabilitation may improve long-term functional outcomes for stroke survivors.
