  1. Data in bold are statistically significant, statistical significance was set at P < 0.05
  2. Calculation was done with device condition and flexion angle as factors and average muscle activation as outcome measure
  3. Separate ANOVA’s were performed for tests with the arms hanging down (Flex only) and the arms stretched forwards
  4. The ‘*’ represents the interaction among device conditions and angles in repeated measures ANOVA
