Following a spinal cord injury (SCI), sensory and motor impairments affect the ability to perform daily life tasks independently, such as transferring or grabbing an object. Intuitively to accomplish these tasks, the use of the upper and lower limbs is obvious, but the trunk is equally essential. Trunk control alterations generate deficits in the functional independence (FI), even in sitting position. However, alteration processes and clear treatment guidelines have not been issued.
