Background & aim: Trunk control loss caused by hemiplegia after stroke can lead to functional disability and compromise balance and postural control during activities. The aim was to verify the association between trunk motor control and disability after stroke. Methods: Prospective cohort with patients over 18 years old, until 1 year of stroke accompanied in rehabilitation center. The Trunk Impairment Scale (TIS) was used to assessed trunk control and functional capacity was assessed by Tinetti Index (TI), Functional Independence Measure (FIM), modified Rankin scale (mRs), and Barthel's Index (BI). Continuous variables were analyzed by Student's t-test or Mann-Whitney test. Results expressed in mean ± standard deviation or median and percentiles and in percentage. Multiple linear regressions were constructed by Stepwise. Level of significance 5%. Results: Ten patients with mean age of 64 (43-74) years, 8.5 (1-26) initial NIHSS score, 8.5 (1-20) days of hospitalization. The TIS presented a negative correlation with mRs (rho=-0.785, p= 0.015), and a positive correlation with BI (r=0.762, p=0.010), FIM (rho=0.783, p=0.007) and TI (rho=0.742, p=0.014). In linear regression there was a significant association between TIS and FIM (β=0.103; p=0.016) and Barthel (β=-0.057; p=0.04). Conclusion: We conclude that the better the motor trunk control, better functional capacity and dependence degree after stroke.
