Among people with PD, recurrent falls are more frequent, with one study reporting that more than 50% of the study participants fell recurrently. In another study involving a survey of 100 people with PD, 13% reported falling more than once a week, with most of these people falling multiple times a day (Allen et al., 2013). Several risk factors for falls have been found to be more strongly associated with recurrent falls than single falls. Some of these factors are potentially modifiable, including cognitive impairment, freezing of gait, fear of falling, reduced mobility, reduced physical activity, and balance impairments (Allen et al., 2013). There is substantial variability in the falling rates reported in various studies, with the proportion of fallers (single and recurrent) ranging from 35% to 95%. Differences in the method of monitoring falls could contribute to this variability (Allen et al., 2013). Despite the fact that recurrent falls are a substantial problem for people with PD, the scope of, and risk factors for, recurrent falls in PD are not clearly understood (Allen et al., 2013).
