Trip-Related Falls by Older Adults

Our efforts to reduce fall-related injuries to older adults were initiated in the late-1980s ( Grabiner and Jahnigen, 1992). Since then, steady advances have led to the present proposal to test the effectiveness of an intervention to reduce falls by older adults in the community. Our most recent work has supported the efficacy of the intervention.

Videos: the following videos show how we induce trips in the laboratory and examples of different fall-mechanisms. For the descritpitions of the mechanisms please refer to Pavol et al., (1999).
