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
