From: Load emphasizes muscle effort minimization during selection of arm movement direction
Directional histograms of statistically significant peaks detected in all individual directional histograms of strokes produced with the dominant (D) and nondominant (ND) arm without load and with load. The major peaks of each histogram were oriented in the diagonal directions, demonstrating that statistically significant peaks of individual histograms were also oriented mainly in these directions.
