Table 3 Mean (SD) gait characteristics stratifying by gait speed and past year fall history.

From: Too much or too little step width variability is associated with a fall history in older persons who walk at or near normal gait speed

  Gait Speed < 1.0   Gait Speed ≥ 1.0 m/s  
  No falls n = 185 ≥ 1 fall n = 37 p-value No falls n = 237 ≥ 1 fall n = 44 p-value
