Rehab Flashcards
At least one foot in contact with ground at one time.
Walking.
Involves period when neither limb is in contact with the ground.
Running.
Distance between initial swing and initial contact of same limb.
Step.
Period from initial contact to initial contact of the same limb.
Stride.
Each stride comprises ____ steps.
Two.
Stance phase occupies ____% of the gait cycle.
60%
Five parts of stance phase.
- Initial contact
- Loading response
- Midstance
- Terminal stance
- Preswing
The swing phase is ____% of gait cycle.
40%
Swing phase starts here.
Toe off (initial swing).
Center of gravity located here.
Just anterior to T10.
Equinus deformity may cause these two gait patterns.
- Steppage
2. Backward setting of knee (recurvatum)
Hemiplegia may cause this gait pattern.
Prolongation of stance and double-limb support.
Increased energy expenditure from average transtibial amputation.
25%.
Increased energy expenditure or bilateral transtibial amputations.
41%
Increased energy expenditure from transfemoral amputation.
65%
More energy expenditure with bilateral transtibial or transfemoral amputations?
Transfemoral
Load transfer methods for amputation levels.
Direct load transfer – knee or ankle disarticulation. Prosthetic socket needed only for suspension.
Total contact method – requires intimate fit of prosthethesis in 7-10 deg flexion of knee. 5-10 deg adduction, flexion of femur for transfemoral.
Gold standard for vascular inflow measurement.
Transcutaneous partial pressure of oxygen.
Transcutaneous partial pressure of oxygen that will correlates with wound healing.
> 40 mmHg
For body-powered upper extremity prostheses the terminal device is activated by this.
Shoulder flexion and abduction.
Myoelectric upper extremity prostheses are most successful with these amputations.
Midlength transradial.
Articulated dynamic-response foot prostheses allow for these motions.
Inversion/eversion, rotation
Types of dynamic-response foot prostheses (2).
- Articulated
2. Non-articulated
The position of the prosthetic knee in relation to the patient’s line of weight bearing.
Alignment stability.
For transtibial prostheses, pistoning in swing phase is usually caused by this.
Ineffective suspension system.
For transtibial prostheses, pistoning in stance phase is usually caused by this.
Poor socket fit or volume changes in stump.
This knee prosthesis has a moving instant center of rotation that provides for different stability characteristics during the gait cycle.
Polycentric (four-bar linkage) knee.
This prosthetic knee functions like a constant-friction knee during the swing phase but “freezes” by application of a high-friction housing when weight applied to limb.
Stance-phase control knee.
This prosthetic knee allows adjustment of cadence response by changing resistance to knee flexion by means of a piston mechanism.
Fluid-control (hydraulic and pneumatic) knee.
Prosthetic foot inset causes pain here in BKA.
Proximomedial and distolateral.
Prosthetic foot outset causes pain here in BKA.
Proximolateral and distomedial.
Forward or posterior prosthetic foot placement in BKA more stable?
Forward.
Lowest level spinal cord injuries for which transfers are dependent.
C4
Spinal cord cord injuries at which transfers may need assistance.
C5
Spinal cord injuries at which transfers become independent.
C6
C5 spinal cord injuries require this wheelchair.
Mouth control.
C6 spinal cord injuries use this propulsion.
Manual.
Polio affects these cells.
Anterior horn cells of spinal cord.
Postpolio syndrome.
Aging phenomenon by which more nerve cells become inactive.
