چکیده انگلیسی
The purpose of this study was to verify the performance of recently developed body-worn sensor packs against 3D motion analysis of trunk and lower-limb movements. Five sensor packs, each consisting of rate gyroscope and two 2-D accelerometers controlled by a microprocessor were attached to the trunk, thighs, and shanks of an able bodied subject. A 6-camera motion analysis system (MAS) recorded multiple trials of sit-to-stand movements and normal walking. Time domain signals from each sensor pack were significantly correlated (r=0.90-0.99;p<0.05) with a root mean square errors of less than 5° when compared against the same limb angle measurements calculated by the MAS. These data demonstrate that these external sensor packs are accurate devices for measuring trunk and lower-limb sagittal plane orientation in real-time.
