Question Answer
What are the likely causes of knee limited flexion in weight acceptance phase?weak quads, knee pain, quad hyperton, forefoot contact with tight gastroc, impaired proprioception.
Why is knee limited flexion NOT a deviation in single leg stance?because the knee is in extension then.
What the the likely causes of limited knee flexion in single leg acceptance phase?quad hyperton, knee extension contracture, impaired motor control, secondary no heel off in TST.
What are the likely causes of excess knee flexion in weight acceptance and single leg stance?secondary increased knee flexion, contracture, secondary increased DF, secondary increased hip flexion (contracture).
What are likely causes of excess knee flexion in single leg acceptance (initial and mid swing)?compensatory to aid clearance secondary to decreased hip flexion or decreased DF.
What are the likely causes of excess knee flexion in single leg acceptance (TERMINAL swing?)knee flexion contracture, weak quads, hamstring hypertone or contracture, poor selective motor control (inability to extend knee while maintaining a flexed hip).
What are the likely causes of knee hyperextension or extension thrust in weight acceptance or single leg stance?secondary excess PF, secondary forefoot contact, weak quads, quad hypertonicity.
