Dependency Coefficient in Computerized GALS Examination Utilizing Motion Analysis Techniques

The GALS (Gait, Arms, Legs and Spine), examination is a compact version of standard procedures used by rheumatologists to determine musculo-skeletal disorders in patients. Computerization of such a clinical procedure is necessary to ensure an objective evaluation. This article presents the first steps in such an approach by outlining a procedure to use motion analysis techniques as a new method for GALS examination.
A 3D motion pattern is obtained from two subject groups using a six camera motion analysis system. The range of motion associated with GALS test is consequently determined using a MATLAB program.
The ROMs for the two subject groups are determined and the validity of the approach is outlined and the symmetry of movement on both sides of the body could is quantified through introduction of dependency coefficient.
Analysis of GALS examination and diagnosis of musculo-skeletal problems could be addressed more accurate and reliable by adopting motion analysis technique. Further, introduction of dependency coefficient offers a wide spectrum of prospective applications in neuro-muscular studies.
