Dependent variables
Primary dependent variables consisted of peak paretic AGRF, TLA, and ankle plantarflexor moment during late stance. Secondary variables included peak non-paretic AGRF, TLA, and ankle plantarflexor moment during late stance. Peak AGRF was calculated as the peak anterior force generation between contralateral heel strike and ipsilateral toe-off averaged across all strides. Peak TLA was calculated as the maximum angle between the greater trochanter and fifth metatarsal head marker averaged across all strides. Peak ankle plantarflexor moment was calculated as the peak plantarflexor moment at terminal stance averaged across all strides. Additionally, percent paretic propulsion was calculated as the peak paretic AGRF divided by the sum of the peak AGRFs for the paretic and non-paretic limbs. A value of 50% paretic propulsion indicates equal contribution to propulsion from the paretic and non-paretic limbs. Inter-limb TLA asymmetry and peak ankle moment asymmetry were calculated as the difference between peak non-paretic and paretic limbs. A positive value indicates a larger non-paretic vs. paretic value, zero indicates symmetry between both limbs, and a negative value indicates a larger paretic vs. non-paretic value. Finally, paretic and non-paretic step lengths were calculated as the antero-posterior distance between the bottom heel markers of the trailing and leading leg, with the leading leg used as reference. Inter-limb differences in step length were calculated as paretic step length ratio [paretic/(paretic + nonparetic step length)].
