Day two MSK: gait Flashcards
How much of gait cycle is single limb support?
Double limb support?
80% single leg
20% double leg
How much of gait cycle is stance?
How much of gait cycle is swing?
60% stance
40% swing
Standard terminology of gait cycle vs. Rancho los amigos
Heel strike --> initial contact Foot flat --> loading Midstance --> midstance Heel off --> terminal stance Toe off --> pre swing acceleration --> initial swing Midswing --> midswing Deceleration --> terminal swing
Gait ROM requirements Hip flexion Hip extension knee flexion Knee extension DF PF
Hip flexion: 0-30 Hip extension: 0-10 knee flexion 0-60 Knee extension: 0 DF: 0-10 PF: 0-20
How do DF act in loading response eccentrically or concentrically?
eccentrically
How do PF act in late phase of loading response eccentrically or concentrically?
eccentrically
How are PF acting in midstance eccentrically or concentrically?
Eccentrically
How are PF acting in temrminal stance eccentrically or concentrically?
Concentrically
When are PF at their peak activity in the gait cycle?
Pre-swing/toe off;
Terminal swing how do hip and knee extensors act eccentrically or concentrically?
eccentrically to control rate of knee extension and hip flexion
where do ankle inverters really come into the gait cycle picture?
Terminal swing: to prepare foot for initial contact/heel strike
BOS increase of decrease with increased cadence?
increases (average is 2-4 inches)
normal cadence is what?
110-120 steps per minute
average toe out is how many degrees
7
Pelvic rotation with or opposite of thorax?
opposite to maintain balance and regulate speed
8 degrees is normal
Average step and stride length (from heel contact to heel contact)
Step: 28 inches
stride: 56 inches
Staggering and unsteadiness in gait with wide BOS is described as what
ataxic
Circumduction normally used to compensate for what three insufficiencies?
hip, knee flexion or DF
What is a double step pattern
alternate steps are different length or rate
High steps, usually involving excessive activity of gastroc is what kind of gait
Equine
What gait pattern is this describing: feet and toes are lited secondary to DF weakness and foot slap is present
steppage
Steppage vs. tabetic
tabetic is ataxic in nature
