-These are just some examples of "clean" foot strikes. The biggest thing to remember, is that if only one foot comes in to contact with a force platform, the force may be considered good. If anything else (other foot, walker, cane, etc.) comes into contact with the plate during stance, the force assignment should be removed.+These are just some examples of "clean" foot strikes.
