What are the causes of gait deviations?
Some of the most common causes of abnormal gait include:
- injuries to the legs or feet.
- arthritis.
- infections in the soft tissue of the legs.
- broken bones in feet and legs.
- birth defects.
- infections in the inner ear.
- cerebral palsy.
- stroke.
What is the most common gait deviation for a novice prosthetic user?
The most common gait abnormality resulting from a leg prosthetic limb length discrepancy of 2.2 cm or less occurs at the pelvis. Resulting in increased coronal plane pelvic obliquity17 when the prosthetic limb during double support is about to make floor contact.
What is prosthetic gait?
Prosthetic alignment alters gait by manipulating the position of LE and prosthetic joints with respect to ground reaction forces (GRF). In normal gait, from initial contact through loading response, ground reaction (GRF) originates at the heel, passing posteriorly to the ankle and knee joints.
What are the types of gait?
What are some types of gait disorders?
- Propulsive gait. This type of gait is seen in patients with parkinsonism.
- Scissors gait. This type of gait gets its name because the knees and thighs hit or cross in a scissors-like pattern when walking.
- Spastic gait.
- Steppage gait.
- Waddling gait.
What is a vaulting gait?
Abstract. Background: Vaulting is a gait compensatory mechanism used by transfemoral amputees to assist toe clearance during the prosthetic swing phase. It is defined by a plantar flexion of the contralateral ankle during the single-limb support phase.
What are the different types of gait?
What causes excessive knee flexion in gait?
Extension of the knee is caused by a contraction of the quadriceps. Flexion is caused by a contraction of the hamstrings, Flexion of the hip is caused by the contraction of the rectus femoris.
What is a 3 point gait?
3 point: this gait pattern is used when one side lower extremity (LE) is unable to bear weight (due to fracture, amputation, joint replacement etc). It involves three points contact with the floor, the crutches serve as one point, the involved leg as the second point, and the uninvolved leg as the third point.
What causes wide based gait?
Ataxic, or broad-based, gait: Acute cerebellar ataxia (uncoordinated muscle movement due to disease or injury to the cerebellum in the brain) Chiari malformation. Alcohol intoxication.
What causes gait deviations in lower limb amputees?
Gait deviations in lower limb amputees can be broadly broken into patient and prosthetic causes: Patient Causes: Muscle weakness. Contracture. Pain. Decreased confidence in the prosthesis or residual limb. Habitual / learned behaviours. Prosthetic Causes: Prosthetic malalignment. Poor fitting prosthetic socket.
What causes a swing deviation in a prosthetic foot?
Swing Deviation Possible Cause Foot “whips” medial or lateral during initial swing •Socket rotated on the patient Prosthetic foot hits the ground •Prosthesis is too long •Suspension is loose •Knee flexion limited
What causes poor gait with a prosthetic foot?
● Prosthetic foot heel too soft (requires a bumper) ● Heel on shoe too low ● Poor gait training Knee flexion is abrupt, instability with knee buckling ● Weak quadriceps ● Foot too posterior ● Socket too flexed, Foot too dorsiflexed ● Heel on shoe is too stiff or too high
Which is the most common transfemoral gait deviation?
Circumducted – this is the most common transfemoral gait deviation; presents when there is a lack of confidence in flexing knee, long prosthesis, excessive knee friction, excessive knee stability; weak hip flexors, or due to habit (using entire hip and pelvis to advance limb)
