This article reports an investigation into the influences of gender, speed of motion and chronological age on the active movements of the lumbar spine. Data were collected from 100 able-bodied volunteers using an automated motion analysis system. Subjects performed movements at two self-selected speeds. Consistent patterns of motion coupling during the actions were detected and no significant gender-specific differences were observed. With advancing age, significant reductions in the ranges of forward and side flexion, but not axial rotation, were found. Age-related differences in the patterns of coupling between movements were also determined. The results of this study will provide therapists with data upon which to base judgments regarding movement restriction, particularly in older clients. © 1995, Australian Physiotherapy Association.
