Exam 3 Study Guide Flashcards
Stage 1 pressure ulcer
Intact skin with
nonblanchable redness of a localized area, usually over a bony prominence. Darkly pigmented skin may not have visible blanching; Its color may differ from the surrounding area.
Stage 2 pressure ulcer
Partial-thickness loss of dermis presenting as a shallow, open ulcer with a red-pink wound bed without slough. May also present as an Intact or open/ruptured, serum-filled blister.
Stage 3 pressure ulcer
Full-thickness tissue loss. Subcutaneous fat may be visible, but bone, tendon, or muscles are not exposed. Slough may be present but does not obscure the depth of tissue loss. May include undermining and tunneling.
Stage 4 pressure ulcer
Full-thickness tissue loss with exposed bone, tendon, or muscle. Slough or eschar may be present on some parts of the wound bed. Often Includes undermining and tunneling.
Duration of wound healing for pressure ulcers
- Stage 1: 1-7 days
- Stage 2: 5-90 days
- Stage 3: 30-180 days
- Stage 4: 180-360 days
turning and positioning schedule

Independent transfer
a transfer by which the individual requires no human assistance to perform.
Modified independent
The patient requires an assistive device or aid, requires more than a reasonable amount of time or there is a safety risk in completing the activity.
Min assist transfer
pt does 75% or more
Mod assist transfer
pt does 50% to 74%
max assist transfer
pt does 25-49%
Dependent transfer
total assist, some sources say <24%
You can teach the pt 3 different ways to position themselves at the edge of the chair.
- Depression lift
- R and L unweighting and scooting
- Backwards lean
Motor Control
the ability to regulate or direct the mechanisms essential to movement
Stages of Motor Control
Mobility, Stability or static postural control, Controlled Mobility or dynamic postural control, and skill
Mobility
availability of range of motion to assume a posture and the presence of sufficient motor unit activation to initiate a movement
Stability or static postural control
the ability to maintain a static steady position in a weight bearing, antigravity posture
Controlled Mobility or dynamic postural control
the ability to maintain a dynamic posture/position in a weight bearing, antigravity posture (standing or sitting weight shifts, controlled movements)
Skill
Mobility is superimposed on stability in non weight bearing conditions
- Also requires a specific goal and a coordinated movement sequence to achieve the goal.
- Skills have a specific purpose, they have voluntary movement control and require a quality of performance (consistency, fluency, timing, economy of effort)
Cognitive
Attempting to understand task
Develop plan
Evaluate response
Associative
Strategy selected
Refinement of skill
Less attention required
Autonomous
Requires little to know attention Can perform other tasks in conjunction
Phases of the sit to stand
Weight shift/flexion momentum
Bottom leaves the seat
Lift/extension
Stabilization
Intrinsic feedback(patients have altered intrinsic feedback)
Feedback that comes to the individual simply through the various sensory systems as a result of the normal production of the movement
Extrinsic feedback
- Augments intrinsic feedback through cueing.
- Example: Telling a patient to lift their leg higher to clear an object while walking
Knowledge of Performance
Feedback relating to the movement pattern used to achieve a goal
Knowledge of Results (form of extrinsic feedback)
Terminal feedback regarding the outcome of the movement
NWB (non–weight-bearing)
foot does not touch ground
TTWB (toe-touch or touch-down WB)
foot contacts ground for balance only or up to 20% of body weight
PWB (partial WB)
usually 20% to 50% of body weight
WBAT (WB as tolerated)
limited only by patient tolerance (>50%)
FWB (full WB)
no restriction (100%)
Four Point Gait Pattern
- Requires use of bilateral ambulation aids
- Very slow and stable pattern (good to use in crowded areas)
- Low energy demand
- Approximates a “normal” gait pattern
3 Point Gait Pattern
- Used when one LE is full weight bearing and the other is NWB
Two Point Gait Pattern
- Used with two or one AD
- Low energy, similar to normal gait
- Requires more coordination and is less stable
“Step to” or “Swing to” Gait Pattern
- The trail LE will only advance as far as the lead LE
- More stable
- Good for cognitive stage of learning
- Slower speed, more taxing
“Step through” or “Swing through” Gait Pattern
- The trail LE with advance past the lead LE
- Increased speed and improved energy conservation
- Decreased stability, requires increased control/balance
Parallel bars advantages
o Maximal stability, support and safety to build skills
o Great place to initiate gait training, balance training and to evaluate fit of other ADs
parallel bars disadvantages
- Severely limits mobility (progress pt as soon as possible)
- Bars must be wide enough for pt to ambulate through
- Not practical
Walkers advantages
- Used when Maximal stability, support, and mobility are required
walkers disadvantages
- Difficult to store/transport, difficult or impossible to use on stairs, decreases speed of ambulation, difficult to perform a normal gait pattern, difficult to use in narrow areas
walkers w/ Trough/Platform Attachments advantages
- Used for patients who are unable to bear weight through their wrists and hands OR have severe deformities of the UE
- May help those with UE amputation or are unable to extend elbow
- Provides additional stability
walkers w/ Trough/Platform Attachments disadvantages
- Unable to use triceps
- May require additional assist
- Not as effective on stairs
- Difficulty to manage in home environment or around obstacles
Crutches advantages
greater selection of gait patterns and able to increase gait speed but still offer stability, adjustable, easily stored, can be used in narrow or crowded spaces.
Crutches disadvantages
less stable than a walker, injury to axillary vessels and nerves if not used or measured properly, need good standing balance, functional strength of the UE and trunk must be considered. Difficult for the elderly to use.
Lofstrand crutches advantages
Able to reach for objects with the crutch remaining on the UE. Eliminate pressure to the axillary vessels and nerves, more functional on stairs and in narrow confined places.
Lofstrand crutches disadvantages
provide less stability and support than axillary crutches, walker or parallel bars, require functional standing balance, UE strength for many gait patterns, forearm cuff can make it difficult to remove, elderly pts feel insecure
Canes advantages
Used to compensate for impaired balance or to improve stability/confidence. More functional on stairs and in narrow confined areas/community areas. Easily transported.
canes disadvantages
very limited BOS due to the base of the cane, not ideal for a 3 point gait pattern or anyone with a weight bearing limitation due to lack of stability.
