Flashcards in OS T#1: S3 Deck (49):

How do you implement Engineering Control Techniques?

By designing or modifying the workstation, work methods/tools to eliminate/ reduce exposure to excessive


When the subtalar joint goes into pronation what happens to the rest of the LE?

The LE goes into medial rotation.


When the subtalar joint goes into supination what happens to the rest of the LE?

The LE goes into lateral rotation.


What effect does flexion have on the spine?

Increases the vertebral foramen spaces and the intervertebral foramen space as well as increases the pressure on the intervertebral discs


What effect does extension have on the spine?

Decreases the vertebral foramen spaces as well as the intervertebral foramen space, decreases pressure on the intervertebral discs


Which spinal position should be avoided with spinal stenosis?



What is a Meta-analysis?

This is a pooling of data of RCTs to yield a larger sample


What is Liposclerosis?

Thickening of the tissue


What are the signs of a venous stasis ulcer?

Location:superior to medial malleolus, hemosiderosis, liposclerosis


When looking at a venous stasis ulcer what is the first thing you should do?

Find the ABI


If the ABI shows decreased arterial perfusion what is contraindicated?

Compression therapies (ABI between 0.5-0.8)


What is the difference between the lurch/ gluteus medius gait and the trendelenburgh gait?

During lurch gait patient shifts weight over the involved hit and pain may be associated, in trendelenburgh gait pt allows contralateral hip to drop and does not shift trunk.


What are the signs and symptoms of Slipped capital femoral epiphysis?

Vague hip pain, decreased hip flex, abd, and internal rot, with a lurch gait


What is the etiology of Bell's palsy?

LMNL involving the Facial nerve (CN VII), acute inflammatory process results in inflammation cutting off this nerve


What are the sings and symptoms of Bell's Palsy?

Weakness of the muscles of facial expression as well as loss of control of salivation and lacrimation. Inability to close one eye. Pt has normal sensation.


What is Arthrogryposis multiplex congenita?

A congenital deformity of the skeleton and soft tissues characterized by limitations in a joint motion and a sausage like appearance of the limbs


What is contraindicated with osteogenesis imperfecta?

PROM and traction secondary to increased risk of fractures


Therapy goals for Osteogenesis Imperfecta?

Joint protection
Maintain/improve joint mechanics
Aerobic activities (ex: swimming)


What are the TUG norms?

Less than or equal to 10 seconds is normal for adults, 11-20 seconds is normal for frail elderly, scores above 30 are indicative of impaired functional mobility and high risk of falls.


How do venous insufficiency ulcers present?

minimal pain, pain decreased with leg elevation, hemosiderin staining, liposclereosis, thin shiny and cyanotic skin.


Define Cheyne-Strokes respiration?

Progressively deeper and faster breaths which decrease into a period of apnea then cycle restarts.


When is the anterior aspect of the glenohumeral joint capsule stressed the most?

during the cocking phase (max ER Ext and abd


What is the recommended time for suctioning to be performed?

10-15 seconds


When to use transparent films?

Stage 1 or 2 ulcers
Autolytic debridement
Skin donor sites
As a cover for hydrophilic powders and hydrogels


Advantages of Transparent Films?

You can see the wound
Doesn't let fluids / bacteria in
Allows for autolytic debridement
Minimizes friction


When to use Hydrocolloids?

Protection of partial thickness wounds
Autolytic debridement of necrosis or slough
Wounds with mild exudate


What are Hydrocolloids?

Adhesive wafers that form a gel like mass over the wound


Advantages of Hydrocolloids?

Non adhesive to healing tissues
Supports autolytic debridement
Maintains a moist environment
Min- mod absorption


What are Hydrogels?

Water or glycerine based gels


When to use Hydrogels

Partial or full thickness wounds
Wounds with necrosis/ slough
Burns and wounds damaged by radiation


Advantages of Hydrogels?

Soothing and cooling
Rehydrate wound beds
Promote autolytic debridement
Conform to wound bed
Amorphous form can be used with an infection present


What are Foam Dressings?

Soft absorbent non woven dressing made from seaweed. Reacts with wound exudate to form a hydrophilic gel (comes in ropes and pads)


What are advantages of Foam dressings?

Insulate wounds
Provide padding
Manage minimal to heavy exudate
Most are non-adherent


When to use Foam Dressings?

Partial and full thickness wounds
Secondary dressing for wounds with packing to add absorption
To provide protection/ insulation


What are Alginates?

Soft absorbent non woven dressings derived from seaweed that have fluffy cotton like apperance


When to use Alginates?

Wounds with moderate to large amounts of exudate
Wounds with exudate and necrosis
Wounds that require packing
Infected and non infected exudate wounds


Advantages of using Alginates?

Absorb up to 20 times their weight in drainage
Fill dead space
Support debridement in the presence of exudate


When to use wet to dry Gauze dressing?

Mechanical debridement of wound


When to use continuously dry Gauze dressing?

Heavily exudating wounds


When to use continuously moist Gauze dressing?

Protection of clean wounds
Autolytic debridement
Delivery of topical needs


With Internal rotation and Extension of the knee which meniscus has tensile and which has compressive forces acting on it?

Medial: Tensile
Lateral: Compressive


With Internal rotation and Flexion of the knee which meniscus has tensile and which has compressive forces acting on it?

Medial: Compressive
Lateral: Tensile


What are the primary functions of the meniscus?

to relive compressive force of the knee and stabilize the joint during motion.


How does UE ergometery compare to LE ergometery?

UE uses lower VO2max and stroke volume but higher HR and BP


Post MI at what RPE level should u exercise?

less than 13


What is the first intervention to be performed with a Pt who has shoulder impingement syndrome?

Instruct the patient in proper postural alignment


When using biofeed back when do you put the electrodes close together?

When targeting a specific muscle


When using biofeedback when do you place the electrodes far apart?

When trying to achieve a general motion.


how do you test motor function of CN IX and CN X
