Background: The proximal trunk stability is a major pre-requisite for balance and coordinated extremity use in daily functional activities. Objective: To evaluate the trunk control in chronic stroke patients , and to determine to what extent it affects balance abilities and functional performance of those patients. Another aim is to detect the best clinical measure that can be used to test trunk muscle control and may predict functional recovery. Patients and Methods: Forty adult post-stroke ambulant patients participated in this study. The testing protocol included assessment of trunk control by Trunk Impairment Scale (TIS), evaluation of balance ability by Biodex Balance System, and assessment of the functional performance by Functional Independence Measure (motor subscale). Results: The mean age of the study sample was 56.1 ±5.45 years. The trunk control was impaired in 39 (97.5%) out of 40 patients. Measures of trunk control were significantly correlated with measures of balance and functional ability. Univariate regression analysis and partial correlation showed that the dynamic sitting balance subscale of the TIS has the highest effect on measures of balance and functional ability. In addition, the patients’ functional performance is strongly dependent on their balance ability. Conclusion: The trunk performance is still impaired in most of chronic stroke patients and it strongly affects their balance and functional abilities. The dynamic sitting balance component of the TIS is a reliable clinical indicator of balance and functional recovery. [Egypt J Neurol Psychiat Neurosurg.  2014; 51(3): 327-331]
