Fall prevention in older people — Stephen Lord at HCSNet

Daniel isn’t the only guy at Neuroanthropology who gets to go to good conferences; last week, while in the throes of a cold brought on by fieldwork with the 15-and-under Sydney city select rugby team, I got to go to the HCSNet Workshop on Speech, Perception and Action held at Western Sydney University.

HCSNet is funded by the Australian Research Council to promote research on human communication. I only got to go to the second day of the two-day conference (because I was cooking meals for 20 hungry rugby hopefuls the first day), but I saw a number of great presentations, including talks by Catherine Best, MARCS Auditory Laboratories, UWS, Beatriz Calvo-Merino, University College London, and Stephen Lord, Prince of Wales Medical Research Institute. I’ll blog soon on Dr. Calvo-Merino, one of the high points of the day, but today I want to make some notes on Prof. Lord’s fascinating research and talk.

Prof. Lord heads the Falls and Balance Research Group. Visit the group’s website for publications and some great information about risk factors for falling. At the conference, Lord discussed the group’s extensive applied research examining different factors that contribute to older people falling and experimental interventions to decrease the contribution of any single factor. The project has created a screening procedure for use by general practitioners to evaluate an older person’s likelihood of falling.

As regular readers know, I’m particularly interested in the way humans maintain equilibrium (see earlier posts, Kids falling down and Equilibrium, modularity, and training the brain-body, and Daniel’s post of some great parkour video, Free Running and Extreme Balance). In the longer of these posts (Equilbrium, modularity…), I specifically discussed how the ‘sense of balance’ is actually a much more complex synthesis of multiple sensory inputs, both exteroception (perception of the world) and interoception (perception of the self).
