Table 1 The estimated knot value and standard error of the knot for each external load

From: Effect of external load on scapular upward rotation during arm elevation: the knot concept

Loads Least mean square Standard error p-value
Unloaded 83.5 2.9 Reference
1 kg 81.2 2.9 0.33
2 kg 81.0 2.9 0.29
3 kg 76.1 2.9 0.01a
4 kg 73.4 3.1 0.001a
5 kg 75.8 3.1 0.02a
  1. a: Indicate significance after Bonferroni corrections
  2. The knot was defined as a point at which the scapular movement kinesiologically changed
