Fiabilidad relativa y absoluta del test de elevación progresiva de carga isoinercial en pacientes afectados por dolor de espalda bajo crónico no específico: un estudio test-retest de 12 semanas

The procedure used for determining the functional capacity by means of the progressive isoinertial lifting test shows high temporal consistence. Thus, it can be used as a method to assess functional capacity of patients with chronic non-specific low back pain enrolled in interventions of less than 12 weeks.
