Knee Range of Motion Primary · Baseline

Participants completed a biomechanical gait analysis session in all testing conditions (NoCDO, CDO Only, Medial, Lateral). Retro-reflective markers were placed on the participants skin and 12 infrared motion capture cameras (120Hz, Vicon Ltd., Oxford, UK) were used to evaluate the motion of the lower limb as participants walked at a controlled walking speed based on leg length. A minimum of three gait cycles were used to calculate mean(SD) values. Sagittal plane knee range of motion (degrees) was measured throughout the gait cycle.

Participants completed a biomechanical gait analysis session in all testing conditions (NoCDO, CDO Only, Medial, Lateral). Retro-reflective markers were placed on the participants skin and 12 infrared motion capture cameras (120Hz, Vicon Ltd., Oxford, UK) and three force plates (1200Hz, AMTI Inc., Watertown, MA) were used to evaluate the motion and loading of the lower limb as participants walked at a controlled walking speed based on leg length. A minimum of three gait cycles were used to calculate mean(SD) values. Peak knee valgus moment was measured during stance phase and normalized to the

Four Square Step Test (4SST) Primary · Baseline

The 4SST (s) is a standardized timed test of balance and agility. Participants start in the lower left quadrant of a Maltese cross setting on the floor and are timed as they move counterclockwise (forward, right, backward, left) and then clockwise (right, forward, left, backward) around the cross. Participants are instructed to move as quickly as they safely can.

Adverse events — posted to ClinicalTrials.gov

Time frame: Study participants were monitored/assessed for adverse advents throughout the duration of the study visit, up to 4 hours. Participants were also instructed to call or email the research team if any adverse events related to the study occurred after completion of the study visit, up to 6 months.. Reporting threshold: 0.05%. Adverse-event reports describe events observed during the trial — not all are caused by the drug.

Sponsor's own description

The proposed study evaluates the effect of medial and lateral wedges and carbon fiber custom dynamic orthoses (CDOs) on lower limb forces and motion during walking. Previous work has used foam wedges of different stiffness and height placed under the heel to alter CDO alignment and alter lower limb mechanics. Medial or lateral wedges have been used by individuals with unilateral knee osteoarthritis in effort to reduce knee loading. In this study, medial and lateral wedges will be placed in participants shoes, with the tall side of the wedge placed on the medial or lateral aspect of the shoes, and participants will walk at controlled and self-selected speeds and complete physical performance measures. Participants will also walk without a CDO. The proposed study will provide evidence that can be used by physicians when treating knee osteoarthritis.
