^aMeta-analysis not possible as Bauer 2005 did not report mean results for gait speed and Richert 2014 included no comparison group or norm values
^bMeta-analysis not possible as Bauer 2005 did not report mean for gait speed and Erlandson 2012a, 2012b & 2014 included no comparison groups or norm values
^cOnly 2 out of 6 studies included in meta-analysis, as Beans 2013 included men only, Scott 2007 & Richert 2011 & 2014 included no comparison groups or norm values (note heterogeneity between samples of the 2 studies included meta-analysis)
^dMeta-analysis not possible, as Bauer 2005 did not report mean results for cadence or gait initiation time
