Validation of inertial measurement units for the assessment of trunk control in subjects with spinal cord injury.

Background: Trunk control (TC) constitutes one of the main objectives in the rehabilitation of people with a spinal cord injury (SCI), but there are few clinically validated tests to assess it. Accelerometers have been proposed as sensitive and suitable procedures to assess TC.

Objective: To evaluate test-retest reliability, construct and criterion validity of accelerometer parameters to assess TC in people with SCI.
