Final Exam - new stuff

Question 1

orthosis positioning

Answer 1

Safe position / antideformity position 
PIP/DIP extension 0
MCP joint flexion at least 70
Wrist extension 20-30
Thumb in palmar abduction 

Functional positioning / resting
Wrist 10-15 extension
MCP joints 15-20 flexion 
PIPs flexion 20-25
DIPs flexion 10 

Consider bony, nerve, and venous anatomy
Incorporate arches
⅔ of the way down the forearm

Question 2

What is the difference between dynamic, static progressive and serial casting for mobilization orthosis fabrication?

Answer 2

Static: Primarily to support, stabilize, protect, immobilize, prevent contractures, modify tone

Serial static: Splint is remolded or replaced to lengthen tissues, restores mobility

Static progressive: Lengthens tissues via a non-dynamic component (Velcro, turnbuckle), restores mobility. Uses a low load force

Dynamic: Has moving parts (elastic component) to permit, control, or restore movement, can act as a substitute for weak muscles

Question 3

high risk groups for cumulative trauma disorders (CTD’s)

Answer 3

New on the job w/ no major previous exposure to repetitive tasks
After a break from this type of activity (vacation or sick leave)
Older workers (35-55 yo)
Gender, females are 10 x more common than men
Type of work, ex: manufacturing could lead to shoulder pain

Question 4

commonly used CTD terms

Answer 4

Repetitive strain injury (RSI), occupational cervico-brachial disorder, overuse syndrome, work related disorders, repetitive trauma disorders, regional musculo-skeletal disorders

Question 5

characteristics of CTD and be able to determine the presence of CTD’s

Answer 5

Condition in soft tissue structures (tendons, tendon sheaths (tenosynovitis), nerves, muscles or blood vessels, trigger points, myofascial pain, bursitis)
Cause or accelerated by repeated stresses and/or awkward motions
Not caused by a single incident (sprain is a single incident)
Each work activity has the potential to cause micro tears in soft tissue structures
Criteria to determine CTD in the workplace can be tendon or nerve related or both*
Symptoms: pain, numbness, tingling; symptoms lasting more than 1 week and/or occuring more than 20 x in the last year; no evidence of acute traumatic onset; no evidence of systemic disease; onset of symptoms occurring with present job

Question 6

levels of CTD

Answer 6

Level 1 - most severe
Level 2
Level 3 - least severe

Question 7

appropriate treatment for CTD conditions

Answer 7

Management of osis or itis: anti-inflammatory medications; NSAID, corticosteroid
Patient education, activity modification, stretches, splint, icing, proximal exercises to strengthen surrounding muscles, regenerative injections, adhering to restrictions

Rotator cuff tendonitis: NO overhead reaching

Short term treatment strategies:
Goal central sensitization
Acute/sub-acute denervation or peripheral
Goal for muscular or ligament strains
Work on posture and activity modification

Question 8

What is BTE? How is it used?

Answer 8

Used for both assessment (strength and endurance) and treatment (work simulation)
ADLs and IADLs
Can be used in ortho, industrial, and neuro settings
Has various settings for: isotonic (eccentric and concentric), isometric, isokinetic (speed remain the same, but resistance can change), PROM, active assisted ROM

Question 9

How is work defined when using BTE

Answer 9

Work = Force x Distance
Power = work/time
In relation to BTE = resistance, repetitions, time

Question 10

What patient populations would the BTE be appropriate for

Answer 10

Evals: work capacity eval
Treatment: acute or work conditioning
Ergonomic analysis
How: torque control, ratchet switch, height adjustment, work head adjustment, work head position, dynamic and static
Can assess: manual dexterity, handling/grasping, ROM, strength, endurance, effects of vibration, effects of repetitions, work tolerance
Do NOT use for pts with degenerative neurological conditions

Question 11

Identify CTDs

Answer 11

Condition in soft tissue structures (tendons, tendon sheaths (tenosynovitis), nerves, muscles or blood vessels, trigger points, myofascial pain, bursitis)
Cause or accelerated by repeated stresses and/or awkward motions
Not caused by a single incident (sprain is a single incident)
Each work activity has the potential to cause micro tears in soft tissue structures

Question 12

Symptoms of carpal tunnel

Answer 12

Pain, tingling, & numbness in the thumb, index, middle, & radial side of ring finger
Tingling in median nerve distribution
Symptoms are worse at night
Hands feel weak in the morning
Pts drops objects more than usual
Difficulty grasping or pinching objects
Difficulty with tasks requiring dexterity, coordination & strength, such as buttoning a shirt, writing with a pen, or opening a jar lid
The muscles at the base of your thumb are smaller and weaker than they used to be.

Question 13

conservative treatment for carpal tunnel

Answer 13

Splinting; for positioning when sleeping & in the daytime splint if the symptoms persist during ADL activities. Splinting reduces swelling. Can be off the shelf (less effective, but less restrictive) or custom made
Medications, injections of corticosteroids
Ergonomics: rest wrist and hands from repetitive activity intermittently, alternate tasks to reduce pressure on the wrist, delegate tasks that aggravate to co workers or family members, modify and change daily activities that aggravate
Patient education
