Participant Flow

26 participants were screened for eligibility between March 2016 and October 2017 at two outpatient clinics (Pate Rehab, Dallas and Baylor Institute for Rehabilitation, Frisco) in Dallas, Texas. Out of the 26 screened participants, 3 did not meet inclusion criteria. 23 participants consented for the study.

Of the 23 consented participants 2 dropped out at baseline due to fatigue. 21 people completed the baseline measurements. 11 were randomized to DA AFO first week group, PLS AFO second week(1 lost to follow up) and 10 were randomized to PLS AFO first week, and DA AFO second week. 20 participants completed both arms.

At baseline Participants were assigned to wearing DA AFO first for all measurements. Upon completion of baseline measurements,11 participants were randomly assigned to practice wearing the DA AFO for the first week and the same 11 participants were randomly assigned to The PLS AFO for the second week. One person was lost to follow up in this group and so only 10 completed the protocol.

Measure
Ankle Foot Orthosis
n=20 Participants
Participants will be assigned to practice with Posterior Leaf spring AFO for a week, then they will be assigned to practice with Double adjustable AFO for another week. Posterior Leaf spring AFO: Posterior Leaf Spring AFO is an over the shelf polypropylene ankle foot orthosis to assist foot drop. Double adjustable AFO: Double adjustable AFO is a custom AFO with double action metal upright joints

SECONDARY outcome

Timeframe: at baseline,1 week with DA AFO, 1 week with PLS AFO

Using GAITRite for Self Selected Velocity (SSV) and Fast paced Velocity (FPV) walk Step symmetry was calculated as the ratio of affected step length over unaffected step length. Step symmetry was calculated for Self Selected Velocity (SSV) and Fast paced Velocity (FPV)

One participant could not complete baseline assessment due to fatigue associated with chemotherapy. IRB was contacted and a new exclusion criteria was added to exclude participants who were currently undergoing chemotherapy at the time of data collection. One participant had another stroke while at home before the final measurement during the second week of practice with the PLS AFO. This was not related to the study intervention, IRB was informed
