Spinal cord injuries affect people’s daily activities and limit their mobility and participation in the community. Adapted sports improve functioning because they supplement the rehabilitation of people who need a wheelchair for mobility. Objective: The aim of this study was to evaluate the functional performance of wheelchair basketball players with spinal cord injury. Method: This cross-sectional study was conducted with 12 athletes. To evaluate their functional performance the Modified Barthel Index, the adapted version of Texas Fitness test, and the medicine ball test were applied. The correlation of functional dependence with other functional performance tests was performed by the nonparametric Spearman test. Results: Six athletes were classified as moderately dependent and six as mildly dependent. The average time for the adapted version of Texas Fitness test was 27.3 ± 3.8 seconds. The average distance for the medicine ball test was 5.2 ± 0.9 meters. We observed a strong negative correlation between the Modified Barthel Index and the adapted version of Texas Fitness test (r = -0.9193, p < 0.0001). Conclusion: The sample group presented as mildly to moderately dependent in carrying out the activities of daily living, with upper limb strength similar to what is described in the literature, but with less agility
