  1. Values are Mean ± Standard Error for n = 3 subjects.
  2. *Indicates a p-value of less than 0.05 showing significant differences between conditions.
  3. Statistical power, P, is reported under the p-value.
  4. Tukey Honestly Significant Difference (THSD) results are reported for metrics with significance.
  5. PM = proportional myoelectric control PMFI = proportional myoelectric control with flexor inhibition
