The Relationship between Independent Transfer Skills and Upper Limb Kinetics in Wheelchair Users

Table 4

Point-biserial correlation coefficients between TAI items and kinetic variables and Spearman’s correlation coefficients between the part 1 summary scores and kinetic variables. The table shows the relationships that were statistically significant and had a medium effect size or larger: ≥ .3 or ≤−.3.
