چکیده انگلیسی
The aim of this study was to develop a new method for quantifying intersegmental motion of the spine in an instrumented motion segment L4-L5 model using ultrasound image post-processing combined with an electromagnetic device. A prospective test-retest design was employed, combined with an evaluation of stability and within- and between-day intra-tester reliability during forward bending by 15 healthy male patients. The accuracy of the measurement system using the model was calculated to be ± 0.9° (standard deviation = 0.43) over a 40° range and ± 0.4 cm (standard deviation = 0.28) over 1.5 cm. The mean composite range of forward bending was 15.5 ± 2.04° during a single trial (standard error of the mean = 0.54, coefficient of variation = 4.18). Reliability (intra-class correlation coefficient = 2.1) was found to be excellent for both within-day measures (0.995-0.999) and between-day measures (0.996-0.999). Further work is necessary to explore the use of this approach in the evaluation of biomechanics, clinical assessments and interventions.
