title: Comparison of lumbar muscle sEMG between health and LBP patients during dynamic back extensions.
abstract: Nonlinear sEMG signal complexity and recurrence quantification analysis (RQA) methods together with the traditional linear spectrum analysis were used to compare the differences between non-specific chronic low back pain patients and healthy subjects, and to evaluate the active physical therapy effects on LBP patients during dynamic isoinertial extension test.
