The value, Avg., indicates the average for both arms. The negative value indicates that the elbow was less extended when wearing the exoskeleton. The zero value indicates that there is no significant difference between wearing and not wearing the exoskeleton (^nsp > 0.05,

^*p < 0.05,

^**p < 0.01, and

^***p < 0.001).
