The paper compares three assessment methods for the measurement of the trunk range of motion (ROM) in flexion-extension movements of subjects suspected of lumbar vertebrae instability (LVI). For five male adults affected by low-back pain and with morpho-dynamic prescription for suspected LVI, ROM was computed: from the analysis of morpho-dynamic radiographs, according to the definition proposed by i) Kapandji and ii) Yang et al.; from the analysis of the flexion-extension movement captured with an optoelectronic acquisition system iii) as the maximum angular stroke in transductors’ displacement, according to a specifically designed custom protocol. Data obtained from optoelectronic acquisitions result comparable with literature values, suggesting the suitability of optoelectronic systems as non-invasive measurement tool for the trunk ROM assessing, to support the physician in the LVI diagnosis.

Abstract
The paper compares three assessment methods for the measurement of the trunk range of motion (ROM) in flexion-extension movements of subjects suspected of lumbar vertebrae instability (LVI). For five male adults affected by low-back pain and with morpho-dynamic prescription for suspected LVI, ROM was computed: from the analysis of morpho-dynamic radiographs, according to the definition proposed by i) Kapandji and ii) Yang et al.; from the analysis of the flexion-extension movement captured with an optoelectronic acquisition system iii) as the maximum angular stroke in transductors’ displacement, according to a specifically designed custom protocol. Data obtained from optoelectronic acquisitions result comparable with literature values, suggesting the suitability of optoelectronic systems as non-invasive measurement tool for the trunk ROM assessing, to support the physician in the LVI diagnosis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
