Table 2.

Comparisons between type C and type S. The Mann-Whitney U comparisons of pro-directional end-range motion between type C and type S. Motion direction and joints for comparison are shown in rows one and two, rows three and four show the joint motion as a mean ± SD of type C and type S. ^aNo data available, insufficient sample size of one group
