Table 2 Contingency table and level of agreement between the current classification and the stages of Sutherland et al.

From: Gait classification for growing children with Duchenne muscular dystrophy

  1. The number of GCs per gait pattern of our classification and stage of Sutherland et al. are given in counts (top of cells) as well as expressed in percentages relative to the total number of GCs classified into the mildly affected gait pattern (cluster one), tiptoeing gait pattern (cluster two) and flexion gait pattern (cluster three) (bottom of cells). The level of agreement was calculated in two ways. For the first approach, the overall agreement (Agree 1 in lighter gray) between both classifications was calculated, corresponding the early stage with the mildly affected gait pattern (cluster one), the transitional stage with the tiptoeing gait pattern (cluster two), and the late stage with the flexion gait pattern (cluster three). For the second approach, the overall agreement (Agree 2 in darker gray) between both classifications was calculated, corresponding the early stage with the mildly affected gait pattern (cluster one), the transitional stage with the flexion gait pattern (cluster three), and the late stage with the tiptoeing gait pattern (cluster two). Abbreviations in alphabetic order: Agree = agreement; GCs = gait cycles; n = number.
