Falls and fall injury are a serious problem for people with LDs (people with LDs experience similar rates of falls as the elderly in the general population but at a younger age), whereby interventions are warranted. Labbased 3D movement analysis will be conducted with adults with LDs who fall during two visits to perform simple tasks (e.g. walking) (once prior to being provided with LSG, and once 6 weeks after wearing the LSGs at home).
