Association of upper limb motor function with muscle tone changes and quality of life in the subacute phase after stroke: a prospective cohort study
To evaluate associations between muscle tone changes, upper limb motor function, and quality of life in patients undergoing subacute stroke rehabilitation.
Key Findings:
Most changes in muscle tone were not significantly associated with improvements in upper limb motor function or quality of life.
Weak negative correlations were found between changes in FMA-UE total score and relaxation time of the flexor digitorum superficialis muscle (r = -0.32, p = 0.016).
Weak negative correlations were also observed between changes in BBT and creep parameter of the latissimus dorsi muscle (r = -0.31, p = 0.017).
Interpretation:
Upper limb motor recovery may occur largely independently of changes in muscle tone and is more closely associated with quality of life.
Limitations:
The study involved a small sample size of 58 patients.
The analysis was a secondary analysis of data from a randomized controlled trial.
Conclusion:
Rehabilitation should prioritize motor control and functional performance rather than focusing primarily on tone reduction.
