Validez de constructo y utilidad clínica del Trunk control test versión argentina en sujetos con secuela de lesión medular espinaln secuela de lesión medular espinal

Introduction: Individuals with adequate trunk control have a greater likelihood of independently performing activities of daily living, regardless of the level or severity of their injury. However, there are currently no valid and reliable tools in Argentina to assess trunk control in this population. This study aimed to determine the construct validity and clinical utility of the Argentine version of the Trunk Control Test (TCT). Materials and Methods: Participants were enrolled through non-probabilistic convenience sampling until the target sample size was reached or up to two years after approval. The required sample size was 50 participants. Inclusion criteria were: individuals aged 15 to 75 years with a diagnosis of spinal cord injury. Exclusion criteria included: other neurological diagnoses, sensory organ impairments, conditions preventing test administration, and/or psychiatric disorders. Results: The sample consisted of 50 individuals, with the median total TCT score approaching the maximum value. Regarding hypothesis testing for construct validity, six moderate, one weak, and four low correlations were found; no differences were observed between known groups. Conclusion: The Argentine version of the TCT showed a moderate correlation with independence and gait. It does not discriminate between individuals with paraplegia or tetraplegia, or between those with complete and incomplete injuries. The administration time was 8 minutes.
