The aim of this study is to analyze the validity, reliability, and responsiveness of the motion capture depth camera in sub-acute and chronic low back pain patients. Methods: Thirty subjects (18–65 years) with non-specific lumbar pain were screened 6 weeks following an episode. RGB-D camera measurements were compared with an inertial measurement unit. Functional tests included climbing stairs, bending, reaching sock, lie-to-sit, sit-to-stand, and timed up-and-go. Subjects performed the maximum number of repetitions during 30 s. Validity was analyzed using Spearman’s correlation, reliability of repetitions was calculated by the intraclass correlation coe_cient and the standard error of measurement, and receiver operating characteristic curves were calculated to assess the responsiveness. Results: The kinematic análisis obtained variable results according to the test. The time variable had good values in the validity and reliability of all tests (r = 0.93–1.00, (intraclass correlation coe_cient (ICC) = 0.62–0.93). Regarding kinematics, the best results were obtained in bending test, sock test, and sit-to-stand test (r = 0.53–0.80, ICC = 0.64–0.83, area under the curve (AUC) = 0.55–84). Conclusion: Functional tasks, such as bending, sit-to-stand, reaching, and putting on sock, assessed with the RGB-D camera, revealed aceptable validity, reliability, and responsiveness in the assessment of patients with low back pain (LBP).enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/Depth cameraMotion capture systemLow back painFunctional testValidationResponsivenessReliabilityDisability evaluationMovementDolor de la región lumbarEvaluación de la discapacidadMovimientoMedical Subject Headings::Persons::Persons::Age Groups::AdolescentMedical Subject Headings::Persons::Persons::Age Groups::AdultMedical Subject Headings::Persons::Persons::Age Groups::Adult::AgedMedical Subject Headings::Phenomena and Processes::Physical Phenomena::Biophysical Phenomena::Biomechanical PhenomenaMedical Subject Headings::Diseases::Nervous System Diseases::Neurologic Manifestations::Pain::Chronic PainMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Disability EvaluationMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Diseases::Nervous System Diseases::Neurologic Manifestations::Pain::Back Pain::Low Back PainMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Persons::Persons::Age Groups::Adult::Middle AgedMedical Subject Headings::Phenomena and Processes::Physiological Phenomena::Physiological Processes::MovementMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Physical Examination::Neurologic Examination::Pain MeasurementMedical Subject Headings::Phenomena and Processes::Musculoskeletal and Neural Physiological Phenomena::Musculoskeletal Physiological Phenomena::PostureMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Physical Examination::Range of Motion, ArticularMedical Subject Headings::Information Science::Information Science::Copying Processes::Video RecordingMedical Subject Headings::Persons::Persons::Age Groups::Adult::Young Adultresearch article32012763Acceso abierto10.3390/s200306891424-8220PMC7038379
