Gait
| Question | Answer |
|---|---|
| What % of the gait cycle is Stance Phase and Swing Phase? | Stance phase = 60% Swing phase = 40% |
| Which Swing phase gait has the greatest amount of knee flexion | End of Initial swing and beginning of Midswing |
| What are the ROM requirements for normal gait with Hip Flexion? | 0-30° |
| What are the ROM requirements for normal gait with Hip Extension? | 0-10° |
| What are the ROM requirements for normal gait with Knee Flexion? | 0-60° |
| What are the ROM requirements for normal gait with Knee Extension? | 0° |
| What are the ROM requirements for normal gait with Ankle DF? | 0-10° |
| What are the ROM requirements for normal gait with Ankle PF? | 0-20° |
| Which phase of gait requires the largest degree of ankle PF? How much is it? | Preswing => 20° |
| During gait, which phase is the Peak Muscle Activity of the Tibialis Anterior? | Peak activity after heel strike => eccentric lowering of foot |
| During gait, which phase is the Peak Muscle Activity of the Gastroc-soleus? | Peak activity during late stance phase with toe off => concentric heel raise |
| During gait, which phase is the Peak Muscle Activity of the Quadriceps group? | TWO periods: - periods during single support of early stance phase - just before initiation of swing phase |
| During gait, which phase is the Peak Muscle Activity of the Hamstring Group? | Peak activity during late swing phase => decelerating unsupported limb |
| What is the average adult cadence? | 110-120 steps/min |
| what is the avg degree of toe-out for an adult? | 7° |
| T/F During running, there is no double support phase? | TRUE |
| What is the avg pelvic rotation during gait? | 8° total = 4° forward w/ swing leg + 4° back w/ stance leg |
| What is the avg step length for an adult? | 28in |
| What is the avg stride length for an adult? | 56in |
| During an Antalgic gait, which side experiences a DECREASED step length? | the involved side is decreased to avoid WB and to dec PAIN |
| What type of Abnormal gait pattern exhibits a wide BOS and exaggerated movements? | Ataxic Gait |
| What issues can lead to compensated Circumduction during gait? | Weak hip flex, knee flex, ankle DF |
| What is an Equine Gait? | characterized by high steps; usually involves excessive gastroc activity |
| Describe 3 characteristics of a Parkinsonian gait | - forward trunk and knee flex - shuffling gait w/ quick and small steps - possible festinating gait |
| What is a cause of Steppage gait? | DF weakness |
| What is Tabetic Gait? | foot slap during initial contact |
| What can cause Knee Hyperextension in Stance? | - weak quads - PF contracture |
| what can cause excessive knee flexion at terminal stance? | - knee flex contracture - hip flex contracture |
