TRUE OR FALSE: Scissoring gait is caused by hip abductor spasticity.
False, it’s hip adductor spasticity
TRUE OR FALSE: Hemiplegic gait is characterized by extension synergy of the lower extremity and the natural swing phase is affected because of stiff LE.
True
TRUE OR FALSE: In Parkinsonian Gait / Festinating Gait, the CoG falls posteriorly.
False, it falls anteriorly
The pt walks fast with a flexed posture to catch it so they won’t lose balance
TRUE OR FALSE: In the antalgic / limping gait, there is a corresponding increase in stance phase on the unaffected side. Likewise, there is a decreased stance phase due to reduced loading response on the affected side.
True
TRUE OR FALSE: The maturity of gait is usually observed at 10 years old.
False, it’s at 7 y/o
TRUE OR FALSE: Stride / gait length usually decreases in elderly persons and increases as the speed of gait increases.
True
TRUE OR FALSE: The more equal step lengths (between R and L), the more symmetrical the person’s gait is.
True
TRUE OR FALSE: An increased cadence means the step length is shorter and the duration of double support time decreases.
True
