MS is the most common cause of disability in young adults. People with Multiple Sclerosis have a life -long need for physiotherapy and exercise interventions due to the progressive nature of the disease and their greater risk of the complications of inactivity (Coote et al 2009). Current evidence suggests there is strong evidence in favour of exercise therapy compared to no exercise therapy in terms of mobility-related activities (Rietberg et al 2006). Most of this evidence comes from inpatient rehabilitation, however, delivering the service in an outpatient setting may be more cost effective, but to date there is little evidence for this provision. People with MS (35%-60%) frequently report balance and mobility as problems (MacAuley 2010). Poor balance & limited mobility lead to falls (Cattaneo et al, 2007; Finlayson et al, 2006). People with MS fall frequently (Gunn et al, 2014). Preventing falls in people with Multiple Sclerosis (PwMS) is important with falls prevalence estimated to be between 50% to 63%. This presentation will focus on a series of studies aimed at understanding falls in people with MS and preventing falls in people with MS.
