“…A more anterior placed COM provides a greater challenge to stability and increases the chance of a fall in the forward direction 18 . This is due to resulting larger external flexion moments about the joints in the stance limb, increasing the demand for resistive muscular force generation 19 . Even in high-functioning, physically active older adults, a perturbation during walking results in an initial destabilisation period 25% longer and re-stabilising the COM takes longer than for young adults 20 .…”

Studying the relationships between centre of mass (COM) and centre of pressure (COP) during walking has been shown to be useful in determining movement stability. The aim of the current study was to compare COM-COP separation measures during walking between groups of older adults with no history of falling, and a history of falling due to tripping or slipping. Any differences between individuals who have fallen due to a slip and those who have fallen due to a trip in measures of dynamic balance could potentially indicate differences in the mechanisms responsible for falls. Forty older adults were allocated into groups based on their self-reported fall history during walking. The non-faller group had not experienced a fall in at least the previous year. Participants who had experienced a fall were split into two groups based on whether a trip or slip resulted in the fall(s). A Vicon system was used to collect full body kinematic trajectories. Two force platforms were used to measure ground reaction forces. The COM was significantly further ahead of the COP at heel strike for the trip (14.3±2.7cm) and slip (15.3±1.1cm) groups compared to the nonfallers (12.0±2.7cm). COM was significantly further behind the COP at foot flat for the slip group (-14.9±3.6cm) compared to the non-faller group (-10.3±3.9cm). At mid-swing, the COM of the trip group was ahead of the COP (0.9±1.6cm), whereas for the slip group the COM was behind the COP (-1.2±2.2cm). These results show identifiable differences in dynamic balance control of walking between older adults with a history of tripping or slipping and non-fallers.

“…Forty volunteer subjects were categorized into two experimental groups: (1) TKR (n = 20) and (2) healthy controls (CON; n = 20) and have been previously described [13]. The experimental protocol was approved by the Institutional Review Board and written consent was obtained from all subjects.…”

“…The control group underwent identical testing at an initial collection period (P1) and at a second period 6 months later (P2). The gait measures were generated from a testing protocol involving level walking and stair ascent, using an eight camera motion analysis system (Motion Analysis Corp., Santa Rosa, CA) and three force plates (Advanced Mechanical Technologies Inc., Newton, MA) which has been previously described [13,16,17]. Briefly, a 33 reflective marker array was applied to the subjects and used to create a 13-segment full body model [18].…”

“…Common problems reported after total ankle arthroplasty (TAA) include residual pain, superficial wound complications, and deep infections as well as limitations in walking speed and gait mechanics [24,25]. These limitations have been attributed in part to deficits in balance, proprioception, muscle strength and postural control [13,3,10,[26][27][28][29][30][31].…”
