As the aging population grows in the United States and across the world, incidence of stroke will grow as age is a key risk factor, thus there will be a need for low-cost, easy-to-use, and scalable solutions to administer proper therapy to promote recovery. This study will evaluate a Variable Friction shoe (VF shoe), a new low-cost medical device, for foot drop in an at-home setting.", "detailedDescription"=>"The investigators propose an alternative strategy that addresses the hazard of tripping even while allowing full volitional control of the ankle: an inexpensive Variable Friction (VF) shoe. Its outsole is high-friction during the stance phase of gait and low friction during swing; further, it produces a \"click\" when a scuff occurs.\n\nThe investigator's central hypothesis is that allowing volitional motion of the ankle while mitigating the hazard of tripping coupled with gait-phased auditory biofeedback will result in improved gait for subjects with drop foot. Specifically, the investigators hypothesize that the VF shoe will show significantly greater therapeutic effects than an AFO, yet maintain the desirable orthotic effect of the AFO. The study is arranged in two Aims.\n\nExploratory Aim: Identify a systematic, methodical approach to device fitting, in-clinic and at-home training with the VF shoe and optimization of collecting outcome measures as assessments. For example, up to 10 participants will be enrolled for up to 8 visits over 12 weeks to determine the optimal data collection methods, fitting and training of use of VF shoes, and order of assessments, etc.\n\nSpecific Aim 1: Characterize the scuff-force reduction of the VF shoe over the lifetime of use. Critical to understanding the effects of the VF shoe is a characterization of the level of scuff-force reduction.\n\nSpecific Aim 2: Evaluate the effects of the VF shoe on gait in individuals with chronic stroke and drop foot. During each 12-week phase of an AB-BA clinical trial, participants will walk for at least 30-45 minutes per day for at least 5 days per week at home."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Inclusion Criteria:\n\n1. 3 months - 1-year poststroke (the period in which patients would typically be fitted with a device for foot drop)\n2.
